    I.    INTRODUCTION
    Alaska Statute 09.55.548(b) provides that when a medical malpractice
    claimant’s losses have already been compensated in part by a collateral source (such as
    an insurer), the claimant’s damages award will be reduced by the value of the collateral
    source compensation, except when the collateral source is a “federal program that by law
    must seek subrogation.” This case presents the questions of whether and how the statute
    applies when the claimant’s losses are compensated by an employer’s self-funded health
    benefit plan governed by the federal Employee Retirement Income Security Act
    (ERISA).1
    We conclude that an ERISA plan does not fall within the statute’s “federal
    program” exception. Therefore AS 09.55.548(b) requires a claimant’s damages award
    to be reduced by the amount of compensation received from an ERISA plan. But we also
    conclude that the distinction the statute draws between different types of medical
    malpractice claimants is not fairly and substantially related to the statute’s purpose of
    ensuring claimants do not receive a double recovery — an award of damages predicated
    on losses that were already compensated by a collateral source. Because insurance
    contracts commonly require the insured to repay the insurer using the proceeds of any
    tort recovery, claimants with health insurance are scarcely more likely to receive a
    double recovery than other malpractice claimants. The statute therefore violates the
    equal protection guarantee of the Alaska Constitution.

    II.    FACTS AND PROCEEDINGS
    A.     Facts
    Plaintiff Charina McCollum alleges that in May 2015 Dr. Thomas
    Knolmayer, M.D., mistakenly cut the wrong duct during a surgery to remove
    McCollum’s diseased gallbladder. As a result McCollum was medevacked from
    Anchorage to Seattle, where she was given a drain to evacuate bile from her abdomen
    until she could have duct repair surgery. Due to problems with bile drainage in June
    2015 she was again medevacked from Anchorage to Seattle and the drain was replaced.
    In August 2015 the duct was surgically repaired.
    McCollum’s husband Jason McCollum was employed by Lowe’s
    Companies, Inc., and most of McCollum’s health care expenses were paid by a health
    plan administered by Lowe’s. The terms of the Lowe’s Plan include a right to
    subrogation, under which the Plan “may, at its discretion, . . . commence a proceeding
    or pursue a claim against any party” for the recovery of all benefits paid by the Plan. The
    Plan’s terms also give it a right to reimbursement from any damages award McCollum
    might recover for her injury:
    The Plan shall be entitled to recover 100% of the benefits
    paid, without deduction for attorneys’ fees and costs or
    application of the common fund doctrine, make whole
    doctrine or any other similar legal theory, without regard to
    whether the Covered Person is fully compensated by his or
    her recovery from all sources. The Plan shall have an
    equitable lien which supersedes all common law or statutory
    rules, doctrines and laws of any State prohibiting assignment
    of rights which interferes with or compromises in any way
    the Plan’s equitable subrogation lien. The obligation exists
    regardless of how the judgment or settlement is classified and
    whether or not the judgment or settlement specifically
    designates the recovery or a portion of it as including
    medical, disability or other expenses. If the Covered
    -3-                                      7631
    Person’s recovery is less than the benefits paid, then the Plan
    is entitled to be paid all of the recovery achieved.
    B.     Proceedings
    In February 2016 McCollum filed a complaint for medical malpractice
    against Knolmayer and Alaska Trauma and Acute Care Surgery, LLC.
    1.     The superior court’s first order on preemption
    McCollum moved for a ruling of law on the recoverability of her medical
    expenses that had been paid by the Lowe’s Plan. Alaska Statute 09.55.548(b) provides
    that “a claimant may only recover damages from the defendant that exceed amounts
    received by the claimant as compensation for the injuries from collateral sources,” with
    the exception of “death benefits paid under life insurance” or collateral sources that are
    “federal program[s] that by law must seek subrogation.” McCollum’s motion argued that
    as an employer-funded benefit plan, the Lowe’s Plan is governed by ERISA, which
    preempts state laws relating to employee benefit plans. McCollum asked the court “to
    hold that ERISA [preempts] the application of AS 09.55.548(b) in this case, and that
    [McCollum] is not precluded from requesting medical damages that include the
    expenditures of the” Lowe’s Plan.
    Knolmayer opposed McCollum’s motion, arguing that ERISA does not
    preempt AS 09.55.548(b). Knolmayer claimed that although ERISA does preempt some
    state laws, “state laws that do not affect coverage or impose requirements upon ERISA
    plans are not preempted.”
    In reply McCollum argued that AS 09.55.548(b) is preempted because it
    affects the Lowe’s Plan’s contractual subrogation and reimbursement rights. To support
    this argument McCollum pointed to a letter from the Plan’s representative, the PHIA
    Group, to McCollum’s counsel stating that “at the time of settlement or resolution of any
    underlying claims, [the Plan] will seek full reimbursement of all related claims paid by
    -4-                                      7631
    the Plan.” At oral argument, McCollum explained that because AS 09.55.548(b) limits
    the amount that McCollum can recover from the defendants, it also potentially limits the
    amount the Lowe’s Plan can recover from McCollum. She argued that because
    AS 09.55.548(b) would result in the Lowe’s Plan recovering less from claimants in
    Alaska than from claimants in states without similar statutory provisions, the statute
    impairs ERISA’s goal of uniform health plan administration across the country.
    Knolmayer, on the other hand, argued that AS 09.55.548 “only governs the defendant’s
    liability to the plaintiff. It does not prevent the [P]lan in any way from seeking
    reimbursement from the plaintiff after this lawsuit has concluded.”
    On October 1, 2018, the court issued an order holding that ERISA does not
    preempt AS 09.55.548(b). The order stated that under AS 09.55.548(b), the plaintiff’s
    award is reduced by the amount the insurer paid in medical expenses; that amount is then
    “set aside by the court to reimburse the insurer.” According to the superior court,
    because the statute did not “prevent the [Plan] from seeking or receiving
    reimbursement,” it did not affect the operation of ERISA plans and therefore was not
    preempted by ERISA.
    2.     The superior court’s order on partial reconsideration
    Knolmayer sought partial reconsideration of the October 1 order. He did
    not challenge the court’s conclusion that ERISA does not preempt AS 09.55.548. But
    he sought reconsideration of the court’s holding that the amount deducted from the
    plaintiff’s recovery would be “set aside” to reimburse the insurer. Knolmayer argued
    that this “set-aside” would contradict the statute’s purpose of reducing the size of
    medical malpractice awards, as well as contradict the common law by allowing the
    subrogated insurer to obtain a recovery that the plaintiff herself could not recover.
    McCollum opposed the motion. She argued that under Knolmayer’s interpretation of
    AS 09.55.548(b), the Lowe’s Plan would be able to “seize” her entire recovery, thus
    -5-                                     7631
    “eviscerat[ing]” the “basic principle of tor[t] law that individuals have basic interests
    protected by law in the event of civil wrong.”
    The court granted partial reconsideration on June 25, 2019. It agreed with
    Knolmayer that AS 09.55.548(b) “forecloses collection of the Plan’s subrogated interest
    against Defendants by Plaintiff.”2 It therefore vacated “those portions of its Order that
    set out a post-trial procedure for earmarking covered medical costs and awarding them
    to the non-party Plan.” However, the court noted that “nothing in AS 09.55.548(b)
    prevents the Plan from recovering on its subrogated interest as a party itself.” The court
    stated that unless the Lowe’s Plan joined as a party, McCollum could not “pursue the
    covered medical costs, regardless of the contract between [McCollum] and the Plan.”
    But the court determined that “[t]he Plan’s subrogation right has not been eliminated by
    the statute,” and that the Plan was still free to join the present action or to bring its own
    action against the defendants.
    3.     The superior court’s clarification order
    McCollum then moved for clarification of the court’s reconsideration order,
    asking whether the Lowe’s Plan could assign its subrogated claim to her. The defendants
    opposed, urging the court to find that even if McCollum received an assignment of the
    Lowe’s Plan’s subrogated claim, her recovery on the claim would still be limited by
    AS 09.55.548(b). The court denied the motion as a request for an advisory opinion.
    In October 2019 McCollum filed a notice to the court that she had “agreed
    to an assignment from” the Lowe’s Plan and that the “actual assignment w[ould] be
    completed in the near future.” Knolmayer responded, arguing that the Plan had to join
    the action as a party itself in order to recover the Plan’s expenditures. McCollum replied
    2
    Emphasis in original.
    -6-                                       7631
    by asking the court whether the proposed assignment would be valid, stating that if it
    would not be, she would instead seek involuntary joinder of the Lowe’s Plan.
    In November 2019 McCollum moved to join the Lowe’s Plan’s
    representative, the PHIA Group, as a co-plaintiff. The defendants opposed, arguing that
    the Lowe’s Plan had exercised its option to ratify McCollum’s action instead of joining
    it and could not be forced to join. They further argued that any claim brought by the
    Plan would be barred by the statute of limitations. In May 2020 the court denied
    McCollum’s motion for joinder.
    On April 30, 2020, the court issued an “Order Vacating & Clarifying
    Orders Re: ERISA Preemption of AS 09.55.548 & Denying Plaintiff’s Motion.” The
    order stated that because of the parties’ confusion regarding the earlier rulings on ERISA
    preemption, “the Court vacates its previous orders (issued October 1, 2018 and June 25,
    2019) and clarifies its holding for the record: ERISA does not preempt AS 09.55.548,
    and AS 09.55.548 applies to this case.” The court held that AS 09.55.548(b) did not
    prevent McCollum from recovering the medical expenses paid by the Lowe’s Plan
    because the Plan falls under the statute’s exception for federal programs that by law must
    seek subrogation. The court reasoned that because the Plan is an employee welfare
    benefit program governed by ERISA, it is a “federal program.” And it reasoned that
    according to the terms of McCollum’s contract with the Plan and the Plan’s letter to
    McCollum’s counsel, “the plan is also required to seek subrogation and
    reimbursement.”3     Thus, “[b]ecause Ms. McCollum’s federally-governed health
    insurance plan constitutes a ‘federal program that by law must seek subrogation’ under
    the statute, evidence of any compensation or payments from her plan is not admissible
    and her damages may not be reduced based on payments received from those sources.”

    4.     Petition for review
    In May 2020 Knolmayer petitioned for review of the superior court’s
    April 30 order, specifically the court’s “holding that [the Lowe’s Plan] is a ‘federal
    program that by law must seek subrogation’ under AS 09.55.548(b).”
    We granted the petition, posing the following questions to the parties and
    inviting the participation of amici curiae:4
    •      First, is the Lowe’s Plan part of a “federal program required by law to seek
    subrogation” for purposes of AS 09.55.548(b)?
    •      If not, does AS 09.55.548(b) bar a medical malpractice plaintiff from
    recovering damages paid by a contractually subrogated insurer?
    •      Can an insurer assign a contractually subrogated claim to a plaintiff for
    collection purposes in a medical malpractice lawsuit, and was there an
    effective assignment in this case?
    •      Does AS 09.55.548(b) as applied to a plaintiff whose insurer has a
    contractual right to collect from the plaintiff’s recovery violate the due
    process or equal protection guarantees of the Alaska Constitution? Or does
    AS 09.55.548(b) require that such contractual subrogation rights be
    invalidated?5
    III.   STANDARD OF REVIEW
    Deciding the correct interpretation of AS 09.55.548, whether the statute’s
    operation may be avoided by the use of assignment, whether this statute is preempted by

    IV.   DISCUSSION
    A.     AS 09.55.548(b)’s Bar On Recovering Damages Compensated By A
    Collateral Source Raises Difficult Questions About Allocation Of Loss
    When The Collateral Source Has Rights Of Subrogation And
    Reimbursement.
    This case concerns how AS 09.55.548(b) affects the recovery of damages
    in a medical malpractice case when the plaintiff’s medical expenses have been paid in
    part by an employer’s self-funded health benefit plan governed by ERISA.
    Historically, a plaintiff’s damages award against a tortfeasor could not be
    “diminished or mitigated on account of payments received by plaintiff from a source
    other than the defendant.”7 The so-called “collateral source rule” was “based on the
    principle that a tort-feasor is not entitled to have his [or her] liability reduced merely
    because plaintiff was fortunate enough to have received compensation for his [or her]
    injuries or expenses from a collateral source.”8 The rule prevented the admission of

    “evidence that the plaintiff was compensated by a collateral source for all or a portion
    of the damages caused by the defendant’s wrongful act.”9
    The Alaska legislature modified the collateral source rule in medical
    malpractice cases in 1976 by enacting AS 09.55.548(b), which provides in relevant part:
    Except when the collateral source is a federal program that by
    law must seek subrogation and except death benefits paid
    under life insurance, a claimant may only recover damages
    from the defendant that exceed amounts received by the
    claimant as compensation for the injuries from collateral
    sources, whether private, group, or governmental, and
    whether contributory or noncontributory.
    This statute prevents a plaintiff from recovering damages for expenses that have already
    been paid by a collateral source — typically an insurer — and thereby receiving a
    windfall. An exception is made for payments from a “federal program that by law must
    seek subrogation.”10 This exception reflects that a federal program like Medicaid is
    legally required to seek recovery of its expenditures attributable to a tort, either by
    pursuing its subrogated claim against the tortfeasor directly or by seeking reimbursement
    9
    22 AM. JUR. 2D. Damages § 779 (2022).
    10
    “Subrogation” is “the substitution of another person in place of the creditor
    to whose rights he or she succeeds in relation to the debt, and gives to the substitute all
    the rights, priorities, remedies, liens, and securities of the person for whom he or she is
    substituted.” 16 GEORGE JAMES COUCH, ET AL., COUCH ON INSURANCE § 222:5 (3d ed.
    2021). We have explained that “[w]hen an insurer pays expenses on behalf of an insured
    it is subrogated to the insured’s claim. The insurer effectively receives an assignment of
    its expenditure by operation of law and contract.” Weston, 445 P.3d at 1021 n.16
    (quoting Dixon v. Blackwell, 
    298 P.3d 185
    , 193 n.38 (Alaska 2013)). The subrogated
    claim belongs to the insurer. 
    Id.
     The insurer may allow the insured to include the claim
    in a suit against a third-party tortfeasor and recoup proceeds directly from the damages
    award, 
    id.,
     or the insurer “may pursue a direct action against the tortfeasor, discount and
    settle its claim, or determine that the claim should not be pursued.” Ruggles, 984 P.2d
    at 512.
    -10-                                       7631
    from the claimant’s recovery.11 Allowing the claimant to recover payments made by a
    subrogated federal program that is obligated to exercise its recovery rights does not result
    in a windfall for the plaintiff, because it is the federal program that ultimately recovers
    this amount.
    Yet Medicaid is not the only collateral source that seeks to recover its
    expenditures on an insured when a tortious third party is responsible. The contract
    between a health plan and an insured commonly gives the health plan express rights of
    subrogation and may also oblige the insured to reimburse the insurer’s payments with
    any damages the insured has recovered from a tortious third party.12 That is the case
    here, where the Lowe’s Plan has a contractual right “to recover 100% of the benefits paid
    . . . without regard to whether the Covered Person is fully compensated by his or her
    recovery from all sources . . . [and] regardless of how the judgment or settlement is
    11
    See 42 U.S.C. § 1396a(a)(25)(B) (mandating that states and local agencies
    seek recovery for Medicaid expenses); AS 47.07.025 (requiring Alaska Medicaid
    recipients to assign their rights to third-party payment for medical care to the State and
    permitting the State to garnish a recipient’s wages or salary to ensure reimbursement).
    The parties assume that Medicare imposes a similar obligation. Although Medicare
    clearly possesses a right to seek reimbursement, see 42 U.S.C. § 1395y(b)(2)(B)(iii), and
    subrogation, see 42 U.S.C. § 1395y(b)(2)(B)(iv), the parties have not pointed to any law
    that gives Medicare a legal obligation to do so.
    12
    See 16 COUCH ET AL., supra note 10, § 226:3 (“Traditionally, an insurer
    who paid its insured’s claim then looked to recover the payments from any third party
    who might have caused the insured’s loss. However, because of various limitations on
    the concept of ‘subrogation,’ . . . as well as to avoid the need to undertake the expense
    of prosecuting its own action against a third party, insurers have in past decades become
    increasingly concerned with their ability to recover back their payments directly from
    their own insureds, by means of ‘reimbursement.’ ”); see also id. § 222:2 (distinguishing
    “subrogation” as “attempts by insurers to recover from a third party” from
    “reimbursement,” which refers to “attempts by the insurer to recover from the entity
    which received the policy proceeds — the insured or a beneficiary — once that entity
    has, in fact, recovered from the third party who is responsible for causing the loss”).
    -11-                                       7631
    classified.” In these cases, the plain language of AS 09.55.548(b) causes the health
    plan’s medical payments to be deducted from the plaintiff’s damages award twice: first
    by the court, applying AS 09.55.548(b), and a second time by the health plan exercising
    its contractual right of reimbursement. This “double deduction” means that the plaintiff,
    instead of receiving a windfall, comes up short.
    The combination of AS 09.55.548(b) and insurers’ contractual rights of
    subrogation and reimbursement can create harsh results for the injured person to the
    advantage of the person’s insurer, which recovers the cost of providing insurance, and
    the tortfeasor, who does not have to pay the full cost of the negligence. For example, a
    severely injured person unable to continue working a strenuous, high-paying job might
    have incurred $500,000 in medical bills, covered by his insurer, and lost $500,000 in
    future income. Under AS 09.55.548(b) the person may not recover the $500,000 paid
    by the insurer. Thus the defendant, who has caused $1 million in damages, is on the
    hook for half the cost of its negligence. As for the $500,000 the person could recover
    as compensation for lost income, the insurer may exercise its contractual right of
    reimbursement and take the entire amount. This person would end up far worse than
    someone who had no insurance at all, who would be able to recover all damages and,
    after paying medical debts, could keep the compensation for lost income.13 Knolmayer
    takes the position that this result is not unfair; it is the result of a legislative policy choice
    to reduce damages awards and the insured’s choice to accept these terms of health
    insurance coverage.
    13
    McCollum maintains that this harsh result is likely to occur in her case. If
    AS 09.55.548(b) precludes her from recovering the $349,049.87 the Plan paid for her
    medical expenses and she is limited to $250,000 in non-economic damages by

    To avoid the risk of such a harsh result, McCollum and amici advance
    several theories of how AS 09.55.548(b) should be interpreted and applied in this case.
    They argue that because McCollum’s health benefit plan is governed by ERISA, it falls
    within the exception for “federal program[s] that must by law seek subrogation,” so
    AS 09.55.548(b) does not preclude her from recovering damages that were compensated
    by the Plan. She argues that AS 09.55.548(b) was not intended to result in a “double
    deduction” for medical malpractice plaintiffs and thus cannot be interpreted to preclude
    her from recovering damages for which the Plan has a right of reimbursement. If these
    interpretations of AS 09.55.548(b) are rejected, she argues that the Plan may assign its
    subrogated claim to her and has done so in this case, allowing her to recover the damages
    that AS 09.55.548(b) would otherwise preclude her from recovering. Alternatively,
    McCollum and amici argue that ERISA preempts the application of AS 09.55.548(b) to
    McCollum’s case.
    Each of these theories raises questions about just how the legislature
    intended AS 09.55.548(b) to operate when the collateral source has rights of subrogation
    and reimbursement — and in particular, who will bear the loss caused by the injury.
    Lurking underneath these questions is the constitutional question of whether the
    legislature’s approach to allocating the loss is consistent with Alaska Constitution’s
    guarantees of equal protection and due process.
    B.     AS 09.55.548(b) Does Not Eliminate Collateral Sources’ Subrogated
    Claims.
    Resolving the parties’ arguments requires us to decide how the legislature
    intended AS 09.55.548(b) to operate and, in particular, how the legislature intended to
    affect collateral sources’ subrogation rights. Put simply, the question is whether the
    legislature intended to preclude only the injured person from recovering the amount of
    collateral source payments or to preclude also the collateral sources themselves from
    -13-                                     7631
    recovering those amounts. Answering this question is the first step to deciding: (1) the
    scope of the “federal program” exception; (2) whether the Lowe’s Plan has a claim it
    could assign to McCollum for collection; (3) whether ERISA preempts AS 09.55.548(b);
    and (4) the legislature’s ultimate purpose in enacting the statute, which is essential to our
    constitutional analysis.
    Knolmayer contends that the legislature did not intend to abrogate collateral
    sources’ subrogation rights. Rather, he contends the legislature intended merely to
    preclude claimants from recovering amounts that equitably belong (under subrogation
    principles)14 to insurers, so that insurers may pursue these amounts from tortfeasors
    directly. McCollum and amici appear to agree with this interpretation. Although the
    parties do not dispute this point, we must independently consider this threshold issue.
    Whether the legislature intended to preserve, eliminate, or otherwise modify
    collateral sources’ subrogation rights is an issue of statutory interpretation. We interpret
    statutes “according to reason, practicality, and common sense, taking into account the
    plain meaning and purpose of the law as well as the intent of the drafters.”15 “Statutory
    construction begins with the language of the statute construed in light of the purpose of
    its enactment.”16 We decide questions of statutory interpretation “on a sliding scale”:
    “the plainer the language of the statute, the more convincing any contrary legislative
    history must be . . . to overcome the statute’s plain meaning.”17 “We give popular or
    14
    See Ruggles, 984 P.2d at 512 (observing that “[w]hen an insurer pays

    common words their ordinary meaning, if the words are not otherwise defined in the
    statute.”18
    The statutory text applies the recovery limitation only to a “claimant.”19 And
    the text clearly distinguishes between a “claimant” and a “collateral source” from which
    a claimant receives compensation. Nothing on the face of the statute suggests a limitation
    on the right of a subrogated insurer to pursue its subrogated claim directly against a
    tortfeasor.
    However, applying the traditional common law rules of subrogation to this
    statutory text supports a colorable argument that collateral sources too are limited from
    recovering these amounts. “[A] subrogated insurer stands in [the] shoes of an insured,
    and has no greater rights than the insured, for one cannot acquire by subrogation what
    another, whose rights he or she claims, did not have.”20 For that reason, the subrogated
    insurer “is subject to all the limitations applicable to the original claim of the subrogor
    [i.e., the insured].”21 By precluding the claimant from recovering damages for losses
    compensated by a collateral source, AS 09.55.548(b) arguably precludes the subrogated
    collateral source from recovering these damages too. And under traditional principles of
    subrogation, the subrogated insurer would have no right to other categories of damages,

    such as pain and suffering or loss of income, that the claimant can still recover.22
    Although the text of AS 09.55.548 does not expressly limit a collateral source’s
    subrogation rights, these subrogation principles raise the possibility that the legislature
    intended to limit recovery by collateral sources as well as claimants.
    The legislative history does not decisively answer this question either.
    Alaska Statute 09.55.548(b) originated as one of 27 recommendations by a Medical
    Malpractice Insurance Commission convened by Governor Jay Hammond.23 In Reid v.
    Williams we described AS 09.55.548(b) as “part of a comprehensive medical malpractice
    reform package intended to alleviate a perceived crisis in medical malpractice insurance
    costs.”24
    It seems fairly clear that the Commission intended to limit the recovery of
    both injured persons and their insurers. The Commission’s final draft of the provision
    that would eventually become AS 09.55.548(b) was similar in many respects to the
    legislation enacted, but the Commission’s draft expressly provided that
    “[n]otwithstanding other provisions of state law, and except as provided in this
    subsection, a collateral source does not have a right of subrogation.”25
    22
    See 16 COUCH ET AL., supra note 10, § 223:94 (“Under the principle that
    an insurer who pays its insured’s claim is only subrogated to the insured’s rights against
    a third party that relate to the same loss compensated by the insurer, it becomes crucial
    to determine whether a settlement or judgment in an action between the insured and the
    third party is, in fact, related to the same loss the insurer has compensated.”).

    -16-                                      7631
    The proviso eliminating collateral source subrogation rights is consistent
    with the Commission’s explanation for what became AS 09.55.548(b). The Commission
    stated:
    [I]t was discovered that frequently a person would be allowed
    an award predicated upon out-of-pocket losses which, in fact,
    were wholly or partially compensated from other or collateral
    sources. The result is potential for double recovery, and the
    presentation of the additional complications of subrogation
    and collateral source liens.
    In determining how to approach eliminating the double
    recovery or subrogation problem, it was determined that
    overall cost would be reduced if the patient was required to
    first utilize the first party coverages to which he is entitled,
    which are much more efficient forms of distribution than
    allowing the full measure of damages in an expensive third
    party proceeding, and then deny the patient the right of
    alleging, in the malpractice action, the items of damage which
    were compensated by collateral sources.[26]
    This discussion indicates that the Commission designed the provision that
    became AS 09.55.548(b) to lower the size of damages awards by targeting: (1) “double
    recovery” by claimants whose losses were already compensated, and (2) the
    “complications of subrogation and collateral source liens.”
    Finally, the proviso eliminating collateral source subrogation rights also can
    explain the “federal program” exception.27 The Commission likely understood that any
    attempt to abolish the subrogation rights of a “federal program that by law must seek

    See AS 09.55.548(b) (providing an exception to the collateral source rule

    -17-                                      7631
    subrogation” would be preempted by federal law.28 Therefore the Commission allowed
    claimants to recover damages that had been compensated by a federal program, ensuring
    that the program’s subrogation rights would remain intact. In sum, it seems clear from
    the Commission’s draft legislation and its report that the Commission intended to
    eliminate the subrogation rights of collateral sources.
    What complicates matters is the fact that the legislature then amended the
    bill based on the Commission’s draft legislation to get rid of the sentence expressly
    eliminating collateral source subrogation rights.29 It is possible that the legislature viewed
    that sentence as redundant in light of the common law rules for subrogation: because the
    claimant could not recover amounts compensated by a collateral source, the principles of
    equitable subrogation would normally preclude the subrogated collateral source from
    doing so.30 Yet it seems unlikely that the legislature eliminated a proviso expressly
    enacting the legislature’s desired policy simply because that policy could be implied by
    the interaction between other statutory provisions and the common law.
    Therefore it seems more plausible that the legislature’s amendment was
    intended to be meaningful. In other words, the legislature may have made a different
    policy choice than the Commission. Rather than reduce the liability of a physician found
    to be negligent by eliminating all recovery of collateral source payments, the legislature

    312 U.S. 52
    , 67 (1941) (explaining, in case
    concerning federal Alien Registration Act, that state law is preempted if it “stands as an
    obstacle to the accomplishment and execution of the full purposes and objectives of
    Congress”).

    -18-                                       7631
    may have intended to eliminate the potential for double recoveries by injured persons
    while allowing their insurers to recover the losses caused by the negligent physician.31
    Unfortunately, there appears to be no explanation of this change in the legislative history.
    It is fair to ask why, if the legislature intended to permit collateral sources
    to pursue subrogated claims directly against the tortfeasor, the legislature retained the
    “federal program” exception. The legislature may have been concerned that even limiting
    the insured’s recovery would be enough to create preemption problems. By limiting the
    plaintiff’s recovery, AS 09.55.548(b) would in some cases impair a federal program’s
    ability to assert a subrogation lien on damages recovered by the insured; the federal
    program would therefore have to secure its interest by pursuing a claim directly against
    the tortfeasor. The legislature may have feared that this degree of interference would
    result in preemption. Alternatively, the legislature may not have viewed the federal
    program exception in terms of preemption at all. Instead, the exception may reflect the
    view that when a federal program is required by law to seek subrogation, there will be no
    31
    This would be a reasonable policy choice, even as part of a statutory
    scheme that seeks to limit malpractice awards overall. Allowing health insurers to
    recover such costs would theoretically lower the cost of health insurance overall,
    effectuating a different allocation of the loss than the Commission chose. As the
    Commission itself observed, “every change in the tort law required the conscious
    recognition that the burden of loss was being wholly or partially shifted to a new or
    different class of persons[,] and the Commission struggled hardest on the equities of who
    should bear the loss.” COMMISSION REPORT, supra note 23, at 10-11. The legislature
    could reasonably reach different conclusions on that question than the Commission. The
    federal district court for the Southern District of New York, interpreting New York’s
    similarly worded statute, pointedly described its understanding of that legislature’s policy
    choice: “Section 4545 prevents double recoveries; it was not intended to deprive
    insurers of their basic subrogation rights . . . . Certainly, § 4545 was not intended to
    create a windfall for the tortfeasor, granting it the benefit of the injured party’s insurance,
    for which it did not pay, as a reward, in effect, for committing a tort and injuring
    another.” In re Sept.

    -19-                                        7631
    chance of double recovery, so the rationale for modifying the collateral source rule does
    not apply to these claimants. Either way, interpreting AS 09.55.548(b) to preserve
    collateral source subrogation rights does not create an irrational result, so it is a plausible
    interpretation of the statute.32 And because the legislature amended the Commission’s
    draft of the legislation in such a significant way, we cannot confidently ascribe the
    Commission’s intent regarding collateral source subrogation rights to the legislature.
    Courts in other jurisdictions have concluded, when interpreting statutes
    worded similarly to AS 09.55.548(b), that those statutes did not abrogate insurers’ rights
    of subrogation. The Supreme Court of Florida, for example, reached this conclusion with
    respect to Florida Statute 627.7372(1), which requires the trial court to “instruct the jury
    to deduct from its verdict the value of all benefits received by the claimant from any
    collateral source.”33 The court reasoned that the statute “does not bar a cause of action
    by either the plaintiff insured or his insurer, it merely limits the plaintiff’s recovery to
    monies to which he is equitably entitled.”34 Thus the court saw no reason “why a health
    insurer should not be entitled to a single recovery of costs caused by the tortfeasor.”35

    The federal district court for the Southern District of New York reached the
    same conclusion with respect to New York’s statute modifying the collateral source rule.36
    The New York statute, like Alaska’s, requires reducing the plaintiff’s damages award by
    the amounts “replaced or indemnified . . . from any collateral source.”37 The court
    rejected the argument that because a subrogated insurer “stands in the shoes” of its
    insured and has only the “derivative and limited rights of the insured,” the statute
    abrogates insurers’ right of subrogation.38 The court reasoned that “[t]he principle of
    subrogation is so embedded in the common law, and would be so radically affected, that
    a very clear legislative intent to disrupt it is required,” yet “[t]he statute contains
    absolutely no language that effects th[at] disruption.”39 Observing the clarity with which
    the statute modified the collateral source rule, the court concluded that “the absence of

    any similar clarity” about eliminating insurers’ subrogation rights weighed against
    interpreting the statute to do so.40
    As that court observed, subrogation is rooted in the common law,41 a
    “creature of equity” with the purpose to “work[] out . . . an equitable adjustment between
    the parties by securing the ultimate discharge of a debt by the person who in equity and
    good conscience ought to pay it.”42 “[S]tatutes will not be interpreted as changing the
    common law unless they effect the change with clarity.”43 We see no clear intent in the
    text or legislative history to abrogate collateral sources’ subrogation rights, and therefore
    we must conclude the legislature intended to preserve them.                    Accordingly
    AS 09.55.548(b) limits the injured party from recovering the amount of collateral source
    payments received but does not preclude the collateral source itself from seeking these
    amounts in a direct action against the tortfeasor.

    from recovering damages compensated by a collateral source such as, in McCollum’s
    case, an insurer: “a claimant may only recover damages from the defendant that exceed
    amounts received by the claimant as compensation for the injuries from collateral sources,
    whether private, group, or governmental, and whether contributory or noncontributory.”

    INTERPRETATION OF LEGAL TEXTS 318 (West 2012).
    -22­                                       7631
    of subrogation or reimbursement, but only “federal program[s] that by law must seek
    subrogation and . . . death benefits paid under life insurance.”44 The existence of an
    exception for death benefits and federal programs that by law must seek subrogation
    indicates that the legislature did not intend to exclude compensation paid by other kinds
    of collateral sources from the statute’s limitation on recovery.45
    McCollum argues that the statute’s proviso for depleted coverage allows
    plaintiffs to recover past medical expenses paid by collateral sources. She focuses on the
    following language in AS 09.55.548(b):
    The court may take into account the value of claimant’s rights
    to coverage exhausted or depleted by payment of these
    collateral benefits by adding back a reasonable estimate of
    their probable value, or by earmarking and holding for
    possible periodic payment under (a) of this section that
    amount of the award that would otherwise have been
    deducted, to see if the impairment of claimant’s rights actually
    takes place in the future.
    McCollum argues that this language means that the trial court has “the option of replacing
    collateral sources ‘exhausted or depleted’ in the post-trial offset hearing if it is established
    that the ‘claimant’s rights’ were actually ‘impaired’ by either reimbursement or
    subrogation.”
    This interpretation is not persuasive. “[C]overage exhausted or depleted by
    payment of these collateral benefits” refers to a situation in which the claimant has a
    limited amount of insurance coverage and the collateral benefits at issue have
    44
    AS 09.55.548(b).

    The principle of expressio unius est exclusio alterius “establishes the
    inference that, where certain things are designated in a statute, ‘all omissions should be
    understood as exclusions.’ ” Alaska State Comm’n for Hum. Rts. v. Anderson,

    -23-                                        7631
    substantially used up that coverage. The statutory text simply does not refer to
    subrogation or reimbursement.
    McCollum also argues, relying on the legislative history of AS 09.55.548(b),
    that the legislature had no intent to force injured persons to bear the loss of the injury so
    as to protect negligent physicians. Therefore, she argues, interpreting AS 09.55.548(b)
    to preclude a claimant like her from recovering damages compensated by a collateral
    source with a contractual right to reimbursement is contrary to legislative purpose. As
    explained further below, we agree with McCollum that the legislature’s purpose in
    enacting AS 09.55.548(b) was to eliminate the potential for a claimant to receive the
    windfall of double recovery, not to force her to shoulder the loss of injury.46 But despite
    this overall purpose, we cannot ignore the plain language of the statute. The legislature
    clearly was aware that collateral sources could have rights of subrogation and exempted
    only certain types of collateral source compensation from the statute. McCollum does not
    point to any legislative history that would suggest the legislature meant something
    different.47
    McCollum also relies on decisions from other jurisdictions to argue that
    AS 09.55.548(b) cannot be interpreted to allow a double deduction. But these decisions
    interpreting laws that modify the collateral source rule in other states are not a persuasive
    guide to interpreting AS 09.55.548(b). In Toomey v. Surgical Services, P.C. the Iowa
    Supreme Court ruled that a statute modifying the collateral source rule precluded the

    recovery of a statutory workers’ compensation lien that would have resulted in the
    claimant receiving a double deduction.48 This conclusion flowed from that court’s
    attempt to harmonize the two statutes.49 In this case, Lowe’s reimbursement right is
    contractual, not statutory, and McCollum does not point us to another statute that would
    require us to interpret AS 09.55.548(b) contrary to its plain terms in order to effectuate
    legislative intent. The Iowa law at issue in Loftsgard v. Dorrian, the second case
    McCollum cites, expressly permitted plaintiffs to present evidence of collateral source
    indemnification or subrogation rights.50 Our statute has no comparable language. These
    decisions therefore do not tell us what the Alaska legislature intended when enacting
    AS 09.55.548(b).
    In re Sept. 11 Litigation51 does not support McCollum’s argument either.
    In that case a federal district court ruled that New York’s similarly worded statute does
    not bar insurers from directly pursuing their subrogated claims against tortfeasors.52 But
    it does not suggest that a claimant could recover these amounts and therefore does not
    suggest that AS 09.55.548(b) should be interpreted that way. Alaska Statute 09.55.548(b)
    does not permit medical malpractice plaintiffs to recover damages already paid by a
    subrogated insurer.

    D.     The Lowe’s Plan Does Not Fall Within The Statutory Exception For
    Federal Programs Required By Law To Seek Subrogation.
    The superior court ruled that the Lowe’s Plan is a “federal program that by
    law must seek subrogation” for purposes of AS 09.55.548(b). This ruling allows
    McCollum to recover damages compensating for the medical expenses covered by the
    Lowe’s Plan, which the Lowe’s Plan may then recoup from McCollum pursuant to its
    contractual right of reimbursement. Knolmayer argues that AS 09.55.548(b)’s federal
    program exception does not apply to self-funded health benefit plans governed by ERISA,
    including the Lowe’s Plan. On this point we agree with Knolmayer.
    1.     The plain meaning of “federal program that by law must seek
    subrogation” does not encompass a privately funded, privately
    administered benefit plan with contractual rights of subrogation
    and reimbursement.
    According to the plain meaning of the statutory text, the Lowe’s Plan is not
    a federal program. “Federal” refers to the federal government;53 “program” is defined by
    Merriam-Webster as “a plan or system under which action may be taken toward a goal.”54
    The United States Supreme Court has referred to Medicare and Medicaid — each an
    amalgamation of federal legislation and regulations that provide for federal funding of
    individual health benefits through administration by federal agencies — as “federal
    programs.”55 By contrast, the Lowe’s Plan is created and funded by Lowe’s Companies,
    Inc., a private corporation, and is administered by its agent. “[N]o agency of the United
    States administers ERISA plans; private employers may administer their own ERISA

    plans or may contract for administration of plans from an independent company.”56 A
    privately funded and operated entity does not fall within the common understanding of
    the term “federal program.”
    McCollum offers an array of arguments for why the Lowe’s Plan is a
    “federal program.” First, she argues that if the legislature intended to limit the exception
    to Medicaid, it would have done so explicitly. Although true that the phrase “federal
    program” is broader than Medicaid alone, that does not mean that the legislature intended
    it to encompass an entity that was not created, funded, or administered by the federal
    government.
    Second, it is not the case, as McCollum argues, that the Lowe’s Plan is a
    “federal program” simply by virtue of being governed by ERISA. ERISA is a federal
    law, but that does not mean that every plan or “program” established under its authority
    is a “federal program” in the straightforward sense of the term: a program of the federal
    government.     Many private actors are comprehensively regulated by the federal
    government — airlines, auto manufacturers, banks — yet are not themselves commonly
    thought of as “federal programs.” McCollum argues that the Lowe’s Plan is a federal
    program because ERISA gives it “the force of federal law.” She points to the fact that
    ERISA allows insured parties, fiduciaries, and plan administrators to sue to enforce the
    terms of ERISA and of specific ERISA plans.57 Yet the existence of a federal cause of

    relief (i) to redress such violations or (ii) to enforce any provisions of this subchapter or
    the terms of the plan.”). See, e.g., Sereboff v. Mid Atl. Med. Servs., Inc.,

    -27-                                        7631
    action to enforce a contract does not make the parties to the contract themselves “federal
    program[s].” Ultimately, the ordinary meaning of the phrase “federal program” does not
    encompass a privately funded and administered health benefit plan.
    The Lowe’s Plan does not satisfy the second element of AS 09.55.548(b)’s
    exception either: it is not an entity that “by law must seek subrogation.” The terms of the
    Plan state that “[t]he Plan may, at its discretion, . . . commence a proceeding or pursue a
    claim against any party or coverage for the recovery of all damages to the full extent of
    the value of any such benefits or conditional payments advanced by the Plan.” Further,
    if the insured party brings her own suit, “[t]he Plan shall be entitled to recover 100% of
    the benefits paid.” McCollum argues that these provisions mean that although the Lowe’s
    Plan has the discretion to seek either subrogation or reimbursement, it is required by law
    to seek one or the other. Not so: the terms assert the Plan’s contractual right to recovery,
    not its obligation to pursue recovery. There is a clear distinction between having the right
    to do something and being compelled by law to do something
    Amicus curiae Premera Blue Cross argues that the assumption that the
    Lowe’s Plan will seek either reimbursement or subrogation is “built into” Lowe’s
    financial reporting to the U.S. Department of Labor,58 pointing to the plan administrator’s
    duty to make sure that the terms of ERISA plans are enforced.59 But although prudent

    financial management of the Lowe’s Plan may call for the Plan administrator to pursue
    subrogation and reimbursement whenever available, financial dictates are not legal
    dictates. And even if the terms of the Lowe’s Plan could be read to require the
    administrator to always seek subrogation or reimbursement, these requirements are still
    only contractual, not legal. “ ‘Law’ connotes a policy imposed by the government, not
    a privately-negotiated contract.”60 The Lowe’s Plan administrator is not required “by
    law” to seek subrogation.
    2.    The legislative history and apparent purpose of AS 09.55.548(b)
    do not support interpreting “federal program that by law must
    seek subrogation” beyond its plain meaning.
    McCollum and Premera argue that the phrase “federal program required by
    law to seek subrogation” should be construed broadly to encompass any entity that by
    virtue of federal law has subrogation and reimbursement rights, such as health benefit
    plans governed by ERISA. Premera focuses on the seeming purpose of the “federal
    program” exception, arguing that the legislature “intended to make an exception for when
    federal law intervened to require reimbursement out of a tort recovery.” Otherwise,
    Premera reasons, the law would impair “claimants’ ability to obtain even a single
    recovery for loss.” McCollum echoes this point, arguing that legislative history indicating
    an intent to balance claimants’ interests against those of insurers and doctors warrants
    interpreting the “federal program” exception broadly enough to include ERISA plans.
    Neither McCollum nor Premera points to any legislative history material that directly

    explains the intent of the “federal program” exception. Instead, their arguments focus on
    the broader purposes of the statute.
    As explained above, the “federal program” exception in AS 09.55.548(b)
    may have originally stemmed from the recognition that any attempt to impair the
    subrogation rights of federal programs would be preempted. And federal programs like
    Medicaid are not the only entities with federally protected subrogation rights. In 1990 the
    U.S. Supreme Court ruled in FMC Corp. v. Holliday that ERISA preempted a
    Pennsylvania statute expressly abolishing insurers’ rights of subrogation and
    reimbursement.61 Accordingly, Premera argues that the “federal program” exception
    should be interpreted to include payments made by ERISA plans that require
    reimbursement because the reimbursement requirement is enforceable by federal law.
    This interpretation, Premera argues, would be consistent with the overall legislative
    purpose of eliminating double recoveries because an ERISA plan is virtually certain to
    exercise its reimbursement rights, precluding any windfall to the claimant.
    But there is scant support for the notion that the legislature considered
    ERISA plans and drafted AS 09.55.548(b) around them. The legislature passed
    AS 09.55.548(b) in 1976.62 ERISA was enacted only two years prior, ERISA itself does
    not address rights of subrogation and reimbursement,63 and the law’s broad preemptive

    scope was not established until years later. It was not until 1990 that the Supreme Court
    decided FMC Corp. So there is little reason to think that the legislature was aware that
    AS 09.55.548(b) might be preempted when applied to claimants covered by ERISA health
    benefit plans. That is why the language of AS 09.55.548(b) exempts payments made by
    a “federal program required by law to seek subrogation” rather than payments by “any
    entity with federally protected rights of subrogation.” Although interpreting the “federal
    program” exception to include ERISA plans may be consistent with the purpose of that
    exception, there is no evidence that is what the legislature intended. Absent such
    evidence, it is not reasonable to interpret “federal program that by law must seek
    subrogation” to include a private entity with a contractual right to seek subrogation.64
    Therefore the Lowe’s Plan — a self-funded health benefit plan governed by
    ERISA, with contractual rights of subrogation and reimbursement — is not a “federal
    program that by law must seek subrogation.” Compensation paid to McCollum by the
    Lowe’s plan is not exempt from AS 09.55.548(b)’s recovery limitation on that ground.

    That AS 09.55.548(b) Precludes Her From Recovering By Having The
    Collateral Source Assign Its Subrogated Claim To Her.
    In the superior court, McCollum suggested that the Lowe’s Plan could
    assign its subrogated claim to her, enabling her to recover the damages that
    AS 09.55.548(b) would otherwise preclude her from recovering. Our order granting the

    petition for review asked the parties to discuss whether an insurer may assign a
    contractually subrogated claim to a plaintiff for collection purposes in a medical
    malpractice lawsuit.65 We conclude that even if a subrogated insurer may assign its claim
    to the insured for collection purposes,66 the claim is still subject to the limitation imposed
    by AS 09.55.548(b). The claimant cannot use assignment to circumvent the statute’s
    limitation on her recovery.
    To resolve this question, it is helpful to consider precisely what occurs when
    an insurer is subrogated to the insured’s claim. As we explained in Ruggles ex rel. Estate
    of Mayer v. Grow, “[w]hen an insurer pays expenses on behalf of an insured it is
    subrogated to the insured’s claim. The insurer effectively receives an assignment of its
    expenditure by operation of law and contract.”67 Accordingly, the insured’s claim is
    assigned to the insurer at the precise moment the insurer pays the costs stemming from
    the incident.68 From that point on, “the subrogated claim belongs to the insurer.”69 “If the
    insurer does not object, the insured may include the subrogated claim in its claim against

    66
    Knolmayer argues that the Lowe’s Plan did not assign its subrogated claim
    to McCollum and that any assignment now would be barred by the statute of limitations
    applicable to malpractice claims. McCollum argues that the Lowe’s Plan effectively
    assigned its subrogated claim to her when it ratified her suit against Knolmayer, so that
    her timely suit includes the Lowe’s Plan’s subrogated claim. We assume without
    deciding that the Plan’s ratification of McCollum’s suit was an effective assignment of
    its subrogated claim.

    a third-party tortfeasor.”70 In other words, a partially subrogated insurer may ratify a
    claim brought by its insured.71 By enacting AS 09.55.548(b) the legislature made
    ratification fruitless because the statute precludes the insured from recovering the amounts
    to which the insurer is entitled.
    McCollum argues, in effect, that a claimant can evade the statutory bar by
    having the subrogated insurer assign the claim to the claimant instead of ratify the
    claimant’s pursuit of the claim. The distinction between “assign” and “ratify” in this
    context is semantic: in both cases, the insurer permits the injured person to pursue the
    insurer’s claim in exchange for the right to recoup the proceeds of the claim from the
    insured. It is quite unlikely that the legislature, which clearly understood the concepts of
    subrogation and ratification when it adopted AS 09.55.548(b),72 intended to allow
    claimants to evade the bar on recovery through the use of this semantic distinction.
    Therefore a claimant cannot recover damages compensated by a collateral source by
    having the collateral source assign its subrogated claim to the claimant.
    F.     ERISA Does Not Preempt AS 09.55.548(b)’s Bar On Claimants’
    Recovery Of Collateral Source Payments.
    Although our order granting the petition for review did not ask the parties
    to address preemption, the parties have devoted a substantial portion of their briefing to
    this question. McCollum and Premera argue that because AS 09.55.548(b) limits a

    claimant’s recovery, the claimant’s insurer may not be able to fully recover its
    expenditures by relying on its contractual reimbursement rights. In these cases the insurer
    would have to pursue its subrogated claim directly against the tortfeasor in order to fully
    recover its interest. Because the statute has the potential to impair insurers’ contractual
    reimbursement rights in this way, McCollum argues, ERISA preempts the statute’s
    application when the collateral source is an employer’s self-funded health benefit plan
    like the Lowe’s Plan. Under this theory McCollum must be allowed to recover from
    Knolmayer the compensation she has received from the Lowe’s Plan, which the Lowe’s
    Plan will in turn recover from her through its contractual right of reimbursement.
    “ERISA pre-empts ‘any and all State laws insofar as they may now or
    hereafter relate to any employee benefit plan’ covered by ERISA.”73 The U.S. Supreme
    Court has explained that ERISA’s pre-emption clause is “conspicuous for its breadth.”74
    The test for ERISA preemption has three steps. First, ERISA preempts
    “every state law that ‘relate[s] to’ an employee benefit plan governed by ERISA,” so a
    court must determine whether a given law “relates to” an ERISA plan.75 If the law does
    not “relate to” a plan governed by ERISA, it is not preempted. Second, under the “saving
    clause,” state laws that would otherwise be struck down are “saved” from ERISA
    preemption if they “regulat[e] insurance.”76 Third, under the “deemer clause,” an ERISA
    plan “shall not be deemed an insurance company, an insurer, or engaged in the business

    of insurance for purposes of state laws ‘purporting to regulate’ insurance companies or
    insurance contracts.”77 Thus, even a state law that is “saved” as a law regulating
    insurance is nonetheless preempted as applied to an ERISA plan. ERISA plans are
    “bound by state insurance regulations insofar as they apply to the plan’s insurer,” but may
    not be directly regulated by such regulations.78
    In the first step of the preemption analysis we ask whether AS 09.55.548(b)
    relates to an ERISA plan.79 The U.S. Supreme Court has held that a law relates to an
    ERISA plan “if it has ‘a connection with or reference to such a plan.’ ”80
    1.     AS 09.55.548(b) does not “refer to” ERISA.
    In FMC Corp. v. Holliday the U.S. Supreme Court ruled that ERISA
    preempted Pennsylvania’s antisubrogation law.81 The statute at issue maintained that
    there would be no right to subrogation or reimbursement “with respect to . . . benefits . . .
    paid or payable” by “[a]ny program, group contract or other arrangement for payment of
    benefits,” which “includ[e], but [are] not limited to, benefits payable by a hospital plan
    corporation or a professional health service corporation.”82 This language — into which
    an ERISA plan, as a “program . . . for payment of benefits,” falls — led the Court to

    79
    The superior court erred by applying this test to determine whether
    McCollum’s claim related to ERISA, rather than whether AS 09.55.548(b) does so. The
    preemption analysis properly focuses on the state law, not a plaintiff’s claim.

    conclude that the law “ha[d] a ‘reference’ to benefit plans governed by ERISA.”83 The
    FMC Corp. decision thus suggested that any statute that applies to ERISA plans satisfies
    the first step of the preemption analysis.
    But the Court has retreated somewhat from such a sweeping rule. Its most
    recent decisions on ERISA preemption articulate a different test: “[a] law refers to
    ERISA if it ‘acts immediately and exclusively upon ERISA plans or where the existence
    of ERISA plans is essential to the law’s operation.’ ”84 The Court’s recent decision in
    Rutledge v. Pharmaceutical Care Management Association provides a useful
    illustration.85 The Arkansas law at issue in Rutledge effectively required pharmacy
    benefit managers to reimburse pharmacies at a price equal to or higher than that which the
    pharmacies paid to buy the drug from wholesalers.86 Rejecting the pharmacies’ argument
    that the law referred to ERISA plans simply because it applied to them, the Court held that
    this law did not refer to ERISA “because it applie[d] to [pharmacy benefit managers]
    whether or not they manage an ERISA plan.”87 Nor was ERISA “essential to the law’s

    . Pharmacy benefit managers (PBMs), the Court explained, are
    “intermediaries between prescription-drug plans and the pharmacies that beneficiaries
    use. When a beneficiary of a prescription-drug plan goes to a pharmacy to fill a
    prescription, the pharmacy checks with a PBM to determine that person’s coverage and
    copayment information. After the beneficiary leaves with his or her prescription, the
    PBM reimburses the pharmacy for the prescription, less the amount of the beneficiary’s
    copayment. The prescription-drug plan, in turn, reimburses the PBM.”

    operation” for largely the same reason: the law regulated pharmacy benefit managers
    regardless of whether the plans they served fell under ERISA.88
    Accordingly the Court has ruled that laws of general applicability — those
    that do not exclusively affect ERISA plans — do not refer to ERISA plans for preemption
    purposes. In New York State Conference of Blue Cross and Blue Shield Plans v.
    Travelers Insurance Co., the Court considered a law imposing a surcharge on hospital
    billing rates for patients covered by insurers others than Blue Cross/Blue Shield,
    presuming such surcharges would be passed on to insurance buyers, including ERISA
    plans.89 The Court rejected the argument that the law referred to an ERISA plan because
    “[t]he surcharges are imposed upon patients and [health maintenance organizations
    (HMOs)], regardless of whether the commercial coverage or membership, respectively,
    is ultimately secured by an ERISA plan.”90 And in California Division of Labor
    Standards Enforcement v. Dillingham Construction, N.A., the Court weighed a law
    permitting public works contractors to pay lower wages to apprentices in approved
    apprenticeship programs.91 “Because it seems that approved apprenticeship programs
    need not necessarily be ERISA plans,” the Court found the law did not “refer to” ERISA
    plans.92
    Alaska Statute 09.55.548(b) does not act immediately and exclusively upon
    ERISA plans. The law does not apply “exclusively” to ERISA plans but to all collateral

    sources other than federal programs that by law must seek subrogation and death benefits
    under life insurance. Nor is ERISA essential to the law’s operation: if ERISA were
    abolished AS 09.55.548(b) would function without a problem. Instead the statute is like
    the pharmacy reimbursement law in Rutledge, the prevailing wage statute in Dillingham,
    or the billing surcharge law in Travelers, all of which were “indifferent” to ERISA.93
    AS 09.55.548(b) does not relate to ERISA under this test.
    2.     AS 09.55.548(b) does not have an impermissible connection with
    ERISA.
    The U.S. Supreme Court’s case law on what constitutes an impermissible
    connection with ERISA plans is more complicated but follows a similar trajectory. In
    FMC Corp. the Court held a Pennsylvania law abolishing collateral source subrogation
    rights had an impermissible connection with ERISA plans because the statute would
    require plans “to design their programs in an environment of differing state regulations.”94
    This, in turn, “would complicate the administration of nationwide plans, producing
    inefficiencies that employers might offset with decreased benefits.”95 The Court
    concluded that such inefficiencies were sufficient to establish a connection to ERISA,

    reflecting its belief that ERISA’s “pre-emptive scope was as broad as its language.”96 A
    state law, the Court explained, has a connection with ERISA benefit plans if it “risk[s]
    subjecting plan administrators to conflicting state regulations.”97
    The Court clarified the scope of this holding in a series of decisions
    culminating in Rutledge, in which it explained what it means for a law to have an
    “impermissible connection” with an ERISA plan.98 The Court noted that ERISA is
    “primarily concerned with pre-empting laws that require providers to structure benefit
    plans in particular ways, such as by requiring payment of specific benefits . . . or by
    binding plan administrators to specific rules for determining beneficiary status.”99 ERISA
    also preempts a state law “if ‘acute, albeit indirect, economic effects of the state law force
    an ERISA plan to adopt a certain scheme of substantive coverage.’ ”100 In analyzing
    preemption, “th[e] Court asks whether a state law ‘governs a central matter of plan
    administration or interferes with nationally uniform plan administration.’ ”101 If so, the
    law is preempted.102
    “Crucially, not every state law that affects an ERISA plan or causes some
    disuniformity in plan administration has an impermissible connection with an ERISA

    plan,” especially “if a law merely affects costs.”103 Therefore the Court ruled in Travelers
    that ERISA did not preempt the surcharge on hospital billing rates for non-Blue
    Cross/Blue Shield insurers, which the Court presumed would be passed on to insurance
    buyers, among them ERISA plans.104 Although the financial effects of the law would
    incentivize ERISA plans to choose Blue Cross/Blue Shield over alternatives, the Court
    held such an indirect economic influence did not create an impermissible connection
    because it did not “bind plan administrators to any particular choice.”105 In other words,
    “ERISA does not pre-empt state rate regulations that merely increase costs or alter
    incentives for ERISA plans without forcing plans to adopt any particular scheme of
    substantive coverage.”106 Accordingly in Rutledge the Court determined that a law
    regulating pharmacy benefit managers by requiring them to reimburse pharmacies at a
    minimum rate “[was] merely a form of cost regulation.”107 Although such costs may be
    passed on to ERISA plans, the Court explained that “cost uniformity was almost certainly
    not an object of pre-emption.”108 “Nor is the effect of [the law] so acute that it will
    effectively dictate plan choices.”109        The Court concluded that the pharmacy

    reimbursement law was a simple cost regulation and did not have an impermissible
    connection with an ERISA plan.110
    Because AS 09.55.548(b) does not abrogate collateral sources’ subrogation
    rights, it does not have the kind of “impermissible connection” with ERISA described by
    the U.S. Supreme Court. The Court’s preemption analysis is concerned with whether a
    state law affects ERISA plans by “dictat[ing] the choices”111 of the plan or “forcing plans
    to adopt [a] particular scheme of substantive coverage.”112 Reducing plaintiffs’ recovery
    by the amount of collateral source payments does potentially increase costs for ERISA
    plans. If AS 09.55.548(b) results in a claimant recovering an amount of damages less
    than the value of collateral source payments, then the ERISA plan will be unable to
    completely recoup its costs through reimbursement. For example, if a plaintiff receives
    $100,000 from her plan but is limited to collecting $80,000 from a tortfeasor by
    AS 09.55.548(b), the ERISA plan will be short $20,000 following reimbursement.
    But ERISA plans may still recover the full amount expended by pursuing
    the subrogated claim directly against the tortfeasor. Though there will be legal costs
    associated with seeking recovery through subrogation, “ERISA does not pre-empt state
    rate regulations that merely increase costs or alter incentives for ERISA plans.”113 Just
    as the surcharge on non-Blue Cross/Blue Shield insurers passed on costs to ERISA plans

    but did not “bind plan administrators to any particular choice,”114 AS 09.55.548(b) may
    increase the cost to ERISA plans of obtaining full recovery but does not prevent them
    from doing so. For that reason AS 09.55.548(b) is quite unlike the Pennsylvania anti-
    subrogation law struck down in FMC Corp. v. Holliday.115 There, the law did dictate
    choices: ERISA plans were barred from seeking recovery of expenses via subrogation
    or reimbursement.116 By contrast, as explained above the Alaska Legislature rejected the
    Medical Malpractice Commission’s proposal to abolish collateral sources’ subrogation
    rights.117 Therefore AS 09.55.548(b) “does not bind plan administrators to any particular
    choice.”118 The economic effects of the statute — the costs associated with collateral
    sources recovering costs via subrogation instead of reimbursement in some instances —
    are not so severe as to effectively “force an ERISA plan to adopt a certain scheme of
    substantive coverage.”119
    For that reason we conclude that AS 09.55.548(b) does not have an
    impermissible connection with ERISA plans. And because the statute neither refers to
    nor has an impermissible connection with ERISA plans, it is not preempted.

    G.     AS 09.55.548(b) Violates The Alaska Constitution’s Equal Protection
    Guarantee.
    In our order granting Knolmayer’s petition for review, we asked the parties
    to address whether AS 09.55.548(b) violates the equal protection guarantee of the Alaska
    Constitution when applied to a plaintiff whose insurer has a contractual right to
    reimbursement from the plaintiff’s recovery. Having considered the parties’ and amici
    curiae’s briefing on this point, we conclude that AS 09.55.548(b) is unconstitutional as
    applied to such claimants.120
    Article 1, section 1 of the Alaska Constitution provides “that all persons are
    equal and entitled to equal rights, opportunities, and protections under the law.” “We
    interpret the equal protection clause ‘to be “a command to state and local governments
    to treat those who are similarly situated alike.” ’ ”121 “The guarantee of equal protection
    under the Alaska Constitution is more robust than that under the United States
    Constitution and so ‘affords greater protection to individual rights than’ its federal
    counterpart.”122

    “Under our equal protection analysis, ‘we first decide which classes must
    be compared.’ ”123 “As a matter of nomenclature we refer to that portion of a [statute] that

    After identifying the classes to be compared, we then apply “a flexible three­

    “the purposes served by a challenged statute.”128 Third, we evaluate “the state’s interest

    scrutinized at these second and third steps depends on the standard chosen by the court
    at the first step.130

    1.     The statute classifies claimants based on the existence and origin
    of collateral source compensation.
    A legislative classification “is defined by the terms of the statute at issue.”131
    Alaska Statute 09.55.548(b) creates two classifications. First, it distinguishes between
    those claimants who receive compensation from collateral sources and those who do not.
    Claimants who receive compensation for their injuries from collateral sources are subject
    to a limitation on their recovery: they cannot recover amounts from the tortfeasor that
    correspond to the amounts of compensation received from the collateral source. By
    contrast, claimants who do not receive collateral source compensation are not so limited
    in their recovery. Second, the statute distinguishes between those whose collateral source
    compensation comes from a “federal program that by law must seek subrogation” and
    those whose compensation comes from all other kinds of collateral sources.132 The former
    group are exempt from the recovery limitations that otherwise apply to those who receive
    compensation from collateral sources.133
    131
    Watson v. State, 
    487 P.3d 568
    , 571 (Alaska 2021).
    132
    The statute also distinguishes those who receive life insurance payments,
    but that distinction is not relevant to our constitutional analysis. See AS 09.55.548(b)
    (“Except when the collateral source is a federal program that by law must seek
    subrogation and except death benefits paid under life insurance, a claimant may only
    recover damages from the defendant that exceed amounts received by the claimant as
    compensation for the injuries from collateral sources . . . .”).
    133
    Knolmayer argues that the classification “between medical malpractice
    plaintiffs with certain collateral sources and those without is a classification that is the
    result of a series of choices made by Ms. McCollum,” including the decision to accept
    health coverage from her husband’s employer’s self-funded health benefit plan, along
    with the accompanying subrogation and reimbursement terms of the plan. But the
    classification between those who receive collateral source compensation from a “federal”
    program, those who receive collateral source compensation from other sources, and those

    2.     These classifications are subject to minimum scrutiny.
    The interests affected by AS 09.55.548(b) are financial, so the lowest level
    of scrutiny applies to the statute’s classifications. We explained in Reid v. Williams —
    also concerning whether AS 09.55.548(b) violated the equal protection clause — that “[a]
    medical malpractice plaintiff’s right to damages is an economic interest, which
    traditionally receives only minimal protection under our equal protection analysis.”134
    This is because the alleged discrimination did not involve a protected class and thus
    merited only “minimal judicial protection.”135 The recovery limits set by AS 09.55.548(b)
    “impose[] only economic burdens, and allocate[] these burdens using criteria that are not
    133
    (...continued)
    who receive no collateral source compensation at all is expressly drawn by the text of
    AS 09.55.548(b). And the suggestion that these classifications are immaterial because
    a person is free to choose a particular health insurance plan and the precise terms and
    conditions that go with it is not persuasive. Almost half of Alaskans, like McCollum,
    receive health insurance through their employer. Health Insurance Coverage of the

    Id.
     These individuals generally are not
    choosing among health care plans based on their preferences; rather, the health care
    coverage they receive is based on where they are employed or what federal eligibility
    guidelines they meet. Their power to select among plans or negotiate plan provisions is
    negligible at best. In reality, most people have little freedom to choose the terms and
    conditions of their health insurance coverage, and the classifications drawn by
    AS 09.55.548(b) are significant in light of that reality.

    presumptively suspect,” so our scrutiny as to the legislature’s aims is “minimal.”136 Thus,
    we must ask whether the classifications created by AS 09.55.548(b) bear “a ‘fair and
    substantial relation’ to attaining ‘legitimate’ government objectives.”137
    3.     The legislative purpose of AS 09.55.548(b) is to reduce the size of
    malpractice awards by eliminating double recoveries.
    The next step of the analysis is to determine the purpose of AS 09.55.548(b).
    We have once before addressed this issue in Reid.138 In that case an injured claimant
    argued that AS 09.55.548(b)’s recovery limitation violated equal protection because it
    unreasonably distinguished between negligent doctors, who were protected by the
    statute’s recovery limitations, and other tort defendants, who are subject to a different
    statute modifying the collateral source rule.139 Applying the “fair and substantial”
    relationship test, we upheld the statute.140 We reasoned that AS 09.55.548(b) was part of
    a broad package of medical malpractice reforms designed to “control medical malpractice
    insurance costs and increase the availability of health care.”141 And we concluded that the
    statute bore a fair and substantial relationship to that goal.142 The special problem of
    medical malpractice insurance and the availability of health care justified the legislature’s

    decision to pare down the collateral source rule more aggressively in medical malpractice
    cases than in other tort cases.
    Our conclusion in Reid that AS 09.55.548(b) had the purpose of reducing
    damages awards against medical providers is not the end of the story in this case. Given
    the differential treatment we focused on in Reid — between physicians and other
    tortfeasors — it was sufficient to consider the statute’s purpose at a high level of
    generality. In other words, all we had to consider was why the legislature treated medical
    malpractice suits differently from other tort lawsuits. To consider the justification for
    how AS 09.55.548(b) treats different classes of medical malpractice claimants based on
    the existence and nature of collateral source compensation, we must dig deeper by closely
    examining the statutory scheme and legislative history.143
    As explained above, the overall goal was to adjust the legal framework for
    medical malpractice claims to control the cost of malpractice insurance.144 Yet it is clear
    that neither the Commission nor the legislature sought to reduce damages awards at all
    costs. For instance, the Commission rejected an absolute limit on the discovery period
    143
    See Com. Fisheries Entry Comm’n v. Apokedak, 
    606 P.2d 1255
    , 1264 n.39
    (Alaska 1980) (disavowing notion that “the judiciary is required to hypothesize or invent
    purposes” for equal protection review because “[c]lose examination of the statutory
    scheme will usually yield several concrete legislative purposes having a substantial basis
    in reality, even if these purposes are not specifically identified in a statutory purpose
    clause”).
    144
    See COMMISSION REPORT, supra note 23, at 15 (proposing changes to
    medical malpractice law “because Alaska would soon be faced with the same frequency
    and severity of problems which [were] genuinely threatening the system in many of the
    other states” and because “many carriers ha[d] designated certain tort law reforms as a
    necessary precondition to underwriting malpractice in a state”).
    -48-                                      7631
    in malpractice cases in part to avoid overly burdening the plaintiff.145 It declined to raise
    the burden of proof in medical malpractice cases because doing so “would make it more
    difficult for the legitimate cases to be adjudicated.”146 And it professed it sought to do “no
    violence to the legitimate rights of persons injured as a result of negligent conduct.”147
    With respect to the provision that became AS 09.55.548(b), the Commission
    explained that it was “unwilling to place arbitrary roadblocks that would preclude the
    legitimate claimant from having recourse to counsel and the courts for redress,” but had
    “discovered that frequently a person would be allowed an award predicated upon out-of­
    pocket losses which, in fact, were wholly or partially compensated from other or collateral
    sources.”148 The clear goal was to reduce damages awards by “eliminating the double
    recovery or subrogation problem.”149
    Knolmayer argues that the legislature had a different, more aggressive
    purpose: to reduce malpractice awards in all cases regardless of the claimant’s potential
    for a double recovery. Echoing the Commission’s observation that “every change in the
    tort law required the conscious recognition that the burden of loss was being wholly or
    partially shifted to a new or different class of persons,”150 Knolmayer argues that the
    legislature sought to reduce the size of damages awards by forcing the injured person to
    bear the loss. He maintains that the legislature’s decision to preserve collateral source

    subrogation rights — a different policy choice than the Commission had endorsed — is
    evidence of a legislative purpose to allow collateral sources to be made whole at the
    expense of their insured.
    Yet it is hard to view the legislature’s decision to preserve collateral source
    subrogation rights as a policy of protecting negligent physicians at the expense of the
    injured person. By preserving collateral source subrogation rights the legislature
    increased the likelihood that the negligent physician would be liable for the full measure
    of harm caused. Under the Commission’s draft legislation, neither the injured claimant
    nor the collateral source could recover compensated medical expenses from the
    tortfeasor.151 Under the version of AS 09.55.548(b) ultimately enacted, a subrogated
    collateral source may collect these amounts directly from the tortfeasor. This shift in the
    statute’s operation — restoring the physician’s liability for the full amount of harm caused
    — undercuts Knolmayer’s argument that AS 09.55.548(b) was intended to shift the
    burden of loss to the claimant. Instead it confirms the view that the legislative purpose
    was to prevent claimants from receiving awards “predicated upon out-of-pocket losses
    which, in fact, were wholly or partially compensated” — i.e. the “potential for double
    recovery” — while preserving insurers’ right to recover these amounts from the
    tortfeasor.152
    Another change the legislature made to the Commission’s draft legislation
    supports the conclusion that the legislature’s purpose for AS 09.55.548(b) was solely to
    eliminate double recoveries rather than shift the burden of loss to the injured person. The
    legislature added a provision to protect against depletion of the claimant’s insurance
    coverage by being forced to rely on the collateral source payments:
    151
    H.B. 574, 9th Leg. 2d Sess. (1976).
    152
    COMMISSION REPORT, supra note 23, at 19.
    -50-                                       7631
    The court may take into account the value of claimant’s rights
    to coverage exhausted or depleted by payment of these
    collateral benefits by adding back a reasonable estimate of
    their probable value, or by earmarking and holding for
    possible periodic payment under (a) of this section that
    amount of the award that would otherwise have been
    deducted, to see if the impairment of claimant’s rights actually
    takes place in the future.[153]
    With this provision, the legislature intended to avoid a situation in which the claimant
    would be adversely affected by being forced to rely on compensation from her insurance
    provider rather than from the tortfeasor. This protection is hard to square with
    Knolmayer’s argument that the purpose of AS 09.55.548(b) was to force injured
    claimants to bear the loss.
    Knolmayer’s argument also relies on a contrast between AS 09.55.548(b)
    and AS 09.17.070, which modified the collateral source rule for other kinds of tort claims.
    The latter statute exempts payments from “collateral sources that do not have a right of
    subrogation by law or contract” from that statute’s recovery limitations.154 Knolmayer
    suggests that the express mention of subrogation in AS 09.17.070 indicates that the
    legislature consciously chose in AS 09.55.548(b) to limit claimants’ damages irrespective
    of the effect of subrogation on their recovery. But AS 09.17.070 was enacted ten years
    153
    AS 09.55.548(b).
    154
    AS 09.17.070(a) provides:
    After the fact finder has rendered an award to a
    claimant, and after the court has awarded costs and
    attorney fees, a defendant may introduce evidence of
    amounts received or to be received by the claimant as
    compensation for the same injury from collateral
    sources that do not have a right of subrogation by law
    or contract.
    -51-                                      7631
    after AS 09.55.548(b) and is therefore not a strong guide as to the legislative purpose
    behind the earlier statute.155 Knolmayer argues further that the legislature amended
    AS 09.55.548 in 1992, after the enactment of AS 09.17.070. But the 1992 amendment
    to AS 09.55.548 was merely a corrective amendment to subsection (a) and had nothing
    to do with the collateral source provisions of subsection (b).156          Thus neither
    AS 09.17.070 nor the 1992 amendments to AS 09.55.548(a) shed light on the legislative
    purpose behind AS 09.55.548(b).
    Given the stated purpose, structure, and drafting history of what became
    AS 09.55.548(b), there is no reason to think that the legislature’s purpose was to reduce
    malpractice damages awards by shifting the burden of loss onto the injured person.
    Instead we conclude that the purpose behind AS 09.55.548(b) was to reduce malpractice
    damages awards by eliminating double recoveries.
    4.     The statutory classifications lack a fair and substantial
    relationship to the legitimate purpose of eliminating double
    recoveries.
    We must therefore consider whether the distinctions drawn by
    AS 09.55.548(b) — limiting the recovery of those who receive compensation from a non-
    federal collateral source — have a fair and substantial relationship to the purpose of
    preventing double recoveries. Under this test, “less important governmental objectives
    will suffice and a greater degree of over/or underinclusiveness in the means-to-ends fit

    will be tolerated.”157 “As a minimum, we require that the legislation be based on a
    legitimate public purpose and that the classification ‘be reasonable, not arbitrary, and . . .
    rest upon some ground of difference having a fair and substantial relation to the object of
    the legislation.’ ”158 In other words, “a substantial relationship between means and ends
    is constitutionally adequate.”159
    The equal protection decisions that Knolmayer cites in defense of
    AS 09.55.548(b) are not controlling here. In Reid we concluded that paring down the
    collateral source rule more for medical malpractice claims than for other tort claims was
    justified by the special problem of the malpractice insurance crisis.160 But we did not
    examine the precise mechanisms by which AS 09.55.548(b) modified the collateral source
    rule for these claims, nor was the issue of subrogation squarely addressed. In C.J. v.
    State, Department of Corrections161 and L.D.G., Inc. v. Brown,162 we upheld statutory
    caps on non-economic damages, deeming them sufficiently related to the legislative
    purpose of lowering liability insurance premiums.163 But the blunt legislative purpose
    behind the damages caps — reducing damages awards by limiting compensation for a
    type of loss viewed as subjective and difficult to measure regardless of whether particular

    claimants are fully compensated164 — is not the purpose behind AS 09.55.548(b). Rather
    AS 09.55.548(b) was intended to reduce damages awards by eliminating double
    recoveries. Because of this statute’s distinct purpose, we must independently assess its
    means-to-ends fit.
    Preventing medical malpractice claimants from receiving double recoveries
    in order to limit the size of malpractice damages awards is a legitimate public purpose.
    But the distinctions drawn by AS 09.55.548(b) do not bear a fair and substantial
    relationship to this goal. The statutory classifications are premised on the assumption that
    claimants who receive compensation for their injuries from non-federal collateral sources
    would receive a double recovery if permitted to recover damages for those injuries from
    the tortfeasor. But this assumption does not reflect reality.165 A claimant like McCollum
    is obligated by the terms of her insurance contract to reimburse her insurer out of any
    recovery.166 These terms are commonplace in health insurance contracts.167 So in the vast
    164
    See C.J., 151 P.3d at 381-82 (crediting legislative judgment that
    noneconomic damage awards are “susceptible to over-estimates of the dollar value of a
    victim’s noneconomic loss” but observing “there will be severely injured persons who
    are under-compensated as a result of this legislation”).
    165
    The legislature clearly was aware of the role of contractual subrogation in
    the medical malpractice context. See COMMISSION REPORT, supra note 23, at 19
    (discussing “subrogation problem”). Yet the legislature may have wrongly assumed a
    subrogated insurer could never recoup its costs from an insured who could not recover
    those costs directly from the tortfeasor in the first place. See 16 COUCH ET AL., 
    supra note 10
    , § 223:145 (“Accordingly, an insurance contract providing generally that the
    insurer is subrogated to the rights of the insured does not itself permit an insurer to
    recover from a third-party tortfeasor until the insured has been made whole by the
    combination of insurance payments and the amount recovered from the tortfeasor, and
    there must be specific language to the contrary to avoid the make whole rule.”).
    166
    It is true, as Knolmayer suggests, that McCollum could have refused
    (continued...)
    -54-                                      7631
    majority of cases, allowing claimants to recover damages from the tortfeasor
    corresponding to the amount of medical expenses paid by their insurers would not create
    a double recovery. Rather, those amounts would flow straight to the insurer through its
    166
    (...continued)
    medical benefits from the Lowe’s Plan and instead sought the entire amount of her
    medical costs from Knolmayer, thereby avoiding the potential for a double deduction
    caused by AS 09.55.548(b). But the possibility that a medical malpractice claimant
    might try to avoid the harmful effects of the statute with such a risky wager has little
    bearing on whether the distinctions drawn by the statute are substantially related to its
    purpose.

    contractual reimbursement right. There is little reason to think insurers will simply leave
    easy money on the table.
    For that reason, malpractice claimants who receive compensation from non­
    federal collateral sources are scarcely more likely to receive a double recovery than those
    covered by Medicaid, which is required by law to seek subrogation, or those whose
    medical expenses were not paid by any collateral source. It is true that not all claimants
    who receive collateral source compensation for their injuries will have to pay it back.168
    A small number of claimants may receive compensation for their injuries from collateral
    sources that are not health plans, such as family members or charity.169 It is also possible
    that some health benefit plans do not give the plan a right of reimbursement, although it
    is hard to imagine why a health plan would forgo that straightforward approach to
    improving its bottom line. But for the most part malpractice claimants who receive
    collateral source compensation for their injuries are not poised to make a double recovery
    when suing a negligent medical provider in tort.
    In a world where subrogation and reimbursement provisions are the norm,
    the statute’s differential treatment of medical malpractice claimants based on the existence
    and type of collateral source compensation is not fairly and substantially related to the
    168
    The statute modifying the collateral source rule for general tort claims
    tracks this distinction, which is key to the likelihood of double recovery. See
    AS 09.17.070(a) (“[A] defendant may introduce evidence of amounts received or to be
    received by the claimant as compensation for the same injury from collateral sources that
    do not have a right of subrogation by law or contract.” (emphasis added)).
    169
    However, it is worth noting that another major source of collateral source
    compensation — workers’ compensation — also gives the collateral source subrogation
    and reimbursement rights that minimize the likelihood of double recovery. See
    AS 23.30.015(b), (g), (i) (permitting an employer or employer’s insurer to recoup its
    workers’ compensation expenditures directly from the third party or from an employee’s
    tort recovery).
    -56-                                      7631
    legitimate purpose of preventing double recoveries.170 We therefore conclude that
    AS 09.55.548(b)’s limitation on recovery of collateral source compensation violates
    Alaska’s equal protection clause when applied to a claimant who receives compensation
    from a collateral source that exercises a right of reimbursement against the claimant’s
    recovery.171
