    LINDEBALD, in her official capacity as
    Director of Washington State Health Care
    Authority,
    Respondent/Cross-Appellant.
    LEE, C.J. — Sarepta Therapeutics, Inc., appeals the superior court’s order denying its
    petition for judicial review under the Washington Administrative Procedure Act (APA), chapter
    34.05 RCW, wherein Sarepta challenged the Washington Health Care Authority’s (HCA)
    application of its prior authorization rules to Sarepta’s drug, EXONDYS 51 (Exondys). The HCA
    cross-appeals the superior court’s order denying its motion to dismiss Sarepta’s petition for lack
    of standing. We hold that Sarepta lacks standing to file its petition for judicial review. Therefore,
    the superior court erred by denying the HCA’s motion to dismiss. Accordingly, we reverse the
    superior court’s order denying Sarepta’s motion to dismiss for lack of standing and dismiss
    Sarepta’s appeal.
    No. 54870-4-II
    FACTS
    A.     BACKGROUND—APPROVAL OF EXONDYS
    Duchenne Muscular Dystrophy (DMD) is a “genetic disorder characterized by the
    progressive loss of skeletal muscle and degeneration.” Clerk’s Papers (CP) at 131. DMD
    primarily affects young boys. “The primary symptoms of [DMD] are caused by a lack of
    dystrophin in the muscle. Children with [DMD] lose the ability to walk independently and most
    become reliant on wheelchairs for mobility by the age of 13.” CP at 131.
    On September 19, 2016, the Food and Drug Administration (FDA) approved Sarepta’s new
    drug application for Exondys pursuant to its accelerated approval regulations. Exondys is a drug
    that treats patients with specific mutations of DMD. “The provision of EXONDYS 51 has been
    shown to result in the production of truncated dystrophin, which hopes to have a positive effect on
    muscle degeneration [by] slowing or halting the progression of [DMD].” CP at 131 (boldface
    omitted). Only 13 percent of all DMD patients have the specific mutation which Exondys treats.
    B.     MEDICAID DRUG REBATE PROGRAM AND HCA’S PRIOR AUTHORIZATION REQUIREMENT
    “Congress created the Medicaid program in 1965 by adding Title XIX to the Social
    Security Act.” Pharmaceutical Research & Mfrs. of America v. Walsh, 
    538 U.S. 644
    , 650, 
    123 S. Ct. 1855
    , 
    155 L. Ed. 2d 889
     (2003). However, before 1990, Medicaid did not specifically address
    outpatient prescription drug coverage. 
    Id. at 651
    . Instead, the Secretary of the Health and Human
    Services would approve individual State plans regulating the coverage of outpatient prescription
    drugs as part of controlling Medicaid costs. 
    Id.
     These individual state plans controlled the
    coverage of outpatient prescription drugs through the use of formularies excluding specific drugs
    from coverage or through prior authorization requirements. 
    Id. at 651-52
    .
    2
    No. 54870-4-II
    In 1990, Congress included the Medicaid Drug Rebate Program (MDRP) in the Omnibus
    Reconciliation Act of 1990. 42 U.S.C. § 1396r-8; Walsh, 
    538 U.S. at 652
    . Under the MDRP, drug
    manufacturers must enter into rebate agreements in order for their drugs to be eligible for coverage
    by Medicaid. 42 U.S.C. § 1396r-8(a)(1). Once a drug manufacturer enters into a rebate agreement
    with either the Secretary or a state, their drugs are considered “covered outpatient drugs” and are
    reimbursable under State Medicaid programs. 42 U.S.C. § 1396r-8(a)(1), (k)(2). Reimbursement
    for covered outpatient drugs is subject to various limitations. 42 U.S.C. § 1396r-8(d). Congress
    specifically included the use of formularies under certain circumstances and the use of prior
    authorization programs. 42 U.S.C. § 1396r-8(d)(1), (4), (5).
    “A State may subject to prior authorization any covered outpatient drug.” 42 U.S.C. §
    1396r-8(d)(1)(A). 42 U.S.C. § 1396r-8(d)(5) provides:
    A State plan under this subchapter may require, as a condition of coverage
    or payment for a covered outpatient drug . . . the approval of the drug before its
    dispensing for any medically accepted indication (as defined in subsection (k)(6))
    only if the system providing for such approval—
    (A) provides response by telephone or other telecommunication
    device within 24 hours of a request for prior authorization; and
    (B) except with respect to the drugs on the list referred to in
    paragraph (2), provides for the dispensing of at least 72-hour supply of a
    covered outpatient prescription drug in an emergency situation (as defined
    by the Secretary).
    The purpose of creating the MDRP was to reduce the cost of prescription drugs to the
    Medicaid program and to ensure that Medicaid recipients had access to a variety of prescription
    drug choices:
    The Committee believes that Medicaid, the means-tested entitlement program that
    purchases basic health care for the poor, should have the benefit of the same
    discounts on single source drugs that other large public and private purchasers
    enjoy. The Committee bill would therefore establish a rebate mechanism in order
    3
    No. 54870-4-II
    to give Medicaid the benefit of the best price for which a manufacturer sells a
    prescription drug to any public or private purchaser. Because the Committee is
    concerned that Medicaid beneficiaries have access to the same range of drugs that
    the private patients of their physicians enjoy, the Committee bill would require
    States that elect to offer prescription drugs to cover all of the products of any
    manufacturer that agrees to provide price rebates.
    H.R. REP. NO. 101-881 at 96-97 (1990), reprinted in 1990 U.S.C.C.A.N. 2017, 2108-09. The
    House Bill report states, “[T]he bill would not affect any authority States have under current law
    to impose prior authorization controls on prescription drugs.” 1990 U.S.C.C.A.N. 2017, 2110.
    The report further explained,
    States that elect to offer prescription drug coverage under their Medicaid
    programs would be required to cover all of the drugs of any manufacturer entering
    into and complying with such an agreement with the Secretary. This requirement
    would take effect April 1, 1991. As under current law, States would have the option
    of imposing prior authorization requirements with respect to covered prescription
    drugs in order to safeguard against unnecessary utilization and assure that
    payments are consistent with efficiency, economy, and quality of care. However,
    the Committee does not intend that States establish or implement prior
    authorization controls that have the effect of preventing competent physicians from
    prescribing in accordance with their medical judgment. This would defeat the
    intent of the Committee bill in prohibiting States from excluding coverage of
    prescription drugs of manufacturers with agreements—i.e., assuring access by
    Medical beneficiaries to prescription drugs where medically necessary.
    1990 U.S.C.C.A.N. 2017, 2110.        “Congress effectively ratified the Secretary’s practice of
    approving state plans containing prior authorization requirements when it created its rebate
    program.” Walsh, 583 U.S. at 652.
    The legislature has delegated the authority of administering Washington’s Medicaid
    program to the HCA. RCW 74.09.530(1)(a). As a part of its administration, the HCA is required
    to “take any necessary actions to control costs without reducing the quality of care when
    reimbursing for or purchasing drugs.” RCW 70.14.050(1). To further this purpose, the legislature
    4
    No. 54870-4-II
    requires the HCA to establish “an evidence-based prescription drug program.”                        RCW
    70.14.050(1).
    The HCA has implemented regulations in the Washington Administrative Code (WACs)
    establishing an evidence-based prior authorization program for health care services and equipment,
    including prescription drugs.1 WAC 182-501-0165(3). Prior authorization determinations are
    based on findings of medical necessity. WAC 182-501-0165(3). Specifically, WAC 182-501-
    0165(3) provides that “[t]he [HCA] authorizes, on a case-by-case basis, [prescription drug
    requests] when [the HCA] determines the service or equipment is medically necessary as defined
    in WAC 182-500-[0]070.” “Medically necessary” is defined as
    a term for describing requested service which is reasonably calculated to prevent,
    diagnose, correct, cure, alleviate or prevent worsening of conditions in the client
    that endanger life, or cause suffering or pain, or result in an illness or infirmity, or
    threaten to cause or aggravate a handicap, or cause physical deformity or
    malfunction. There is no other equally effective, more conservative or substantially
    less costly course of treatment available or suitable for the client requesting the
    service. For the purposes of this section, "course of treatment" may include mere
    observation or, where appropriate, no medical treatment at all.
    WAC 182-500-0070 (medical necessity rule).
    Medical necessity determinations are based on submitted medical evidence 2 and an
    evidence-based rating system. WAC 182-501-0165(3). The evidence-based rating system is
    1
    Prescription drugs are considered health care services. WAC 182-501-0050 (“For the purposes
    of this section, health care services includes treatment, equipment, related supplies, and drugs.”).
    2
    The HCA considers the following medical evidence:
    (4) The agency reviews available evidence relevant to a medical, dental, or
    behavioral health service or equipment to:
    (a) Determine its efficacy, effectiveness, and safety;
    (b) Determine its impact on health outcomes;
    5
    No. 54870-4-II
    codified under WAC 182-501-0165(6) (hierarchy of evidence rule). Under the hierarchy of
    evidence rule, “[t]he [HCA] uses a hierarchy of evidence to determine the weight given to available
    data.” WAC 182-501-0165(6)(a). And “[b]ased on the quality of available evidence, the [HCA]
    determines if the requested service is effective and safe for the client by classifying it as an ‘A,’
    ‘B,’ ‘C,’ or ‘D’ level of evidence.” WAC 182-501-0165(6)(b).
    An “A” level classification “[s]hows the requested service or equipment is a proven benefit
    to the client’s condition.” WAC 182-501-0165(6)(b)(i). A “B” level classification “[s]hows the
    requested service or equipment has some proven benefit.” WAC 182-501-0165(6)(b)(ii). A “C”
    level classification “[s]hows only weak and inconclusive evidence regarding safety, or efficacy, or
    both.” WAC 182-501-0165(6)(b)(iii). And a “D” level classification “[i]s not supported by any
    (c) Identify indications for use;
    (d) Evaluate pertinent client information;
    (e) Compare to alternative technologies; and
    (f) Identify sources of credible evidence that use and report evidence-based
    information.
    (5) The agency considers and evaluates all available clinical information
    and credible evidence relevant to the client’s condition. The provider responsible
    for the client’s diagnosis, or treatment, or both, must submit with the request
    credible evidence specifically related to the client’s condition including, but not
    limited to:
    (a) A physiological description of the client’s disease, injury, impairment,
    or other ailment;
    (b) Pertinent laboratory findings;
    (c) Pertinent X-ray and/or imaging reports;
    (d) Individual patient records pertinent to the case or request;
    (e) Photographs, or videos, or both, if requested; and
    (f) Objective medical/dental/behavioral health information such as
    medically/dentally acceptable clinical findings and diagnoses resulting from
    physical or behavioral health examinations.
    WAC 182-501-0165(4), (5).
    6
    No. 54870-4-II
    evidence regarding its safety and efficacy, for example that which is considered investigational or
    experimental.” WAC 182-501-0165(6)(b)(iv). Based on the evidence classification, the agency:
    (i) Approves “A” and “B” rated requests if the service or equipment:
    (A) Does not place the client at a greater risk of mortality or morbidity than
    an equally effective alternative treatment; and
    (B) Is not more costly than an equally effective alternative treatment.
    (ii) Approves a “C” rated request only if the provider shows the requested
    service is the optimal intervention for meeting the client’s specific condition or
    treatment needs, and:
    (A) Does not place the client at a greater risk of mortality or morbidity than
    an equally effective alternative treatment;
    (B) Is less costly to the agency than an equally effective alternative
    treatment; and
    (C) Is the next reasonable step for the client in a well-documented tried-
    and-failed attempt at evidence-based care.
    (iii) Denies “D” rated requests unless:
    (A) The requested service or equipment has a humanitarian device
    exemption from the [FDA]; or
    (B) There is a local institutional review board (IRB) protocol addressing
    issues of efficacy and safety of the requested service that satisfies both the agency
    and the requesting provider.
    WAC 182-501-0165(6)(c).
    C.     HCA’S MEDICAL NECESSITY DETERMINATIONS FOR EXONDYS
    In May and June 2019, the HCA received requests for prior authorization for Exondys from
    three Medicaid patients with DMD. In June 2019, the HCA denied each of the requests for prior
    authorization because it determined that Exondys was not medically necessary for the three
    patients. The HCA concluded that Exondys had a level “D” evidence rating and that “[g]iven the
    lack of effectiveness noted in the FDA label, the low quality of the clinical trials, an unchanged
    trajectory of change for the 6MWT, and continued significant functional decline in multiple
    functional domains, the best available evidence does not support the efficacy of and therefore
    medical necessity of [Exondys].” CP at 147. In other words, because each of the three Medicaid
    7
    No. 54870-4-II
    patients failed to show clinical responsiveness to Exondys, and because they continued to decline
    while taking the drug, the HCA concluded that Exondys was not medically necessary.
    On August 27, 2019, the HCA amended its earlier denial letters by changing the evidence
    rating of Exondys to “C.” The HCA also explained that the denials were based on each patient’s
    failure to show clinical responsiveness to Exondys.
    In October 2019, the Medicaid patients’ treating physician requested a peer-to-peer
    consultation with the HCA’s medical officer who made the initial medical necessity
    determinations. The treating physician provided new information demonstrating that the Medicaid
    patients were obtaining minor therapeutic benefits from using Exondys. Based on this information,
    the HCA’s medical officer determined that Exondys was medically necessary for the three patients
    and provided instructions to the HCA to approve the requests for prior authorization.
    D.        PROCEDURAL HISTORY
    On July 12, 2019, Sarepta filed a petition for judicial review under the APA. Specifically,
    Sarepta sought declaratory judgment invalidating the HCA’s hierarchy of evidence rule as it
    applies to reimbursement for Exondys.3 Later, Sarepta amended the petition to also include a
    challenge to the validity of the medical necessity rule.
    The HCA filed a motion to dismiss Sarepta’s petition for judicial review, arguing that
    Sarepta lacked standing under the APA. The superior court denied the HCA’s motion to dismiss
    for lack of standing. The superior court also denied Sarepta’s petition for judicial review on the
    merits.
    3
    RCW 34.05.570(2)(a) provides, “A rule may be reviewed by petition for declaratory judgment
    filed pursuant to this subsection.”
    8
    No. 54870-4-II
    Sarepta appeals and the HCA cross-appeals.
    ANALYSIS
    The HCA cross-appeals the superior court’s order on the amended petition,4 arguing that
    the superior court erred by denying the HCA’s motion to dismiss because Sarepta lacked standing
    to bring its petition for judicial review under the APA. We agree.
    A.     LEGAL PRINCIPLES
    We review standing de novo. Center for Biological Diversity v. Dep’t of Fish & Wildlife,
    14 Wn. App. 2d 945, 981, 
    474 P.3d 1107
     (2020). The petitioner bears the burden of establishing
    standing. KS Tacoma Holdings, LLC v. Shorelines Hr'gs Bd., 
    166 Wn. App. 117
    , 127, 
    272 P.3d 876
    , review denied, 
    174 Wn.2d 1007
     (2012).
    Judicial review of an agency action is governed by the APA. Patterson v. Segale, 
    171 Wn. App. 251
    , 257-58, 
    289 P.3d 657
     (2012). A party has standing to obtain judicial review of an
    agency action if that person is aggrieved or adversely affected by the agency action. RCW
    34.05.530. A party is aggrieved or adversely affected when three conditions are present:
    (1) The agency action has prejudiced or is likely to prejudice that person;
    (2) That person's asserted interests are among those that the agency was
    required to consider when it engaged in the agency action challenged; and
    (3) A judgment in favor of that person would substantially eliminate or
    redress the prejudice to that person caused or likely to be caused by the agency
    action.
    4
    The HCA’s cross-appeal alleges that the superior court erred by denying its motion to dismiss
    of lack of standing. Because standing is required for a party to obtain judicial review under the
    APA, we address the HCA’s cross-appeal before Sarepta’s appeal on the merits of the petition.
    See RCW 34.05.530.
    9
    No. 54870-4-II
    RCW 34.05.530(1)-(3).5 All three requirements must be established for a person to have standing.
    Allan v. Univ. of Wash., 
    140 Wn.2d 323
    , 326-27, 
    997 P.2d 360
     (2000).
    The first and third requirements of this standing test are collectively referred to as the
    “‘injury-in-fact’ test.” Patterson, 171 Wn. App. at 258 (quoting Allan, 140 Wn.2d at 327). Under
    the “injury-in-fact” test, the petitioner must show that the agency decision caused some specific
    and perceptible harm. Freedom Found. v. Bethel School Dist., 14 Wn. App. 2d 75, 86, 
    469 P.3d 364
     (2020), review denied, 
    196 Wn.2d 1033
     (2021). In other words, there must be an invasion of
    a legally protected interest. Snohomish County Pub. Transp. Benefit Area v. Pub. Emp't Relations
    Comm'n, 
    173 Wn. App. 504
    , 513, 
    294 P.3d 803
     (2013).
    Where “a party alleges a threatened injury, ‘as opposed to an existing injury,’ the party
    must prove that the threatened injury is ‘immediate, concrete, and specific’” in order to have
    standing under the APA. City of Burlington v. Liquor Control Bd., 
    187 Wn. App. 853
    , 869, 
    351 P.3d 875
    , review denied, 
    184 Wn.2d 1014
     (2015) (quoting Trepanier v. City of Everett, 
    64 Wn. App. 380
    , 383, 
    824 P.2d 524
     (1992)). “Conjectural or hypothetical injuries are insufficient to
    confer standing.” Freedom Found., 14 Wn. App. 2d at 86. Finally, the petitioner must show that
    5
    In addition to the standing requirements under RCW 34.05.530, RCW 34.05.570(2)(b)(i)
    requires a person challenging an agency rule to show that the rule or its threatened application
    “interferes with or impairs or immediately threatens to interfere with or impair the legal rights or
    privileges of the petitioner.” Furthermore, challenges to agency rules are brought through a
    declaratory judgment action. RCW 34.05.570(2)(a). A justiciable controversy is required to bring
    a declaratory judgment action. To-Ro Trade Shows v. Collins, 
    144 Wn.2d 403
    , 410-11, 
    27 P.3d 1149
     (2001), cert. denied, 
    535 U.S. 931
     (2002). A justiciable controversy requires (1) an actual,
    present, and existing dispute, (2) between parties with opposing interests, (3) involving direct and
    substantial interests, and (4) for which a judicial determination will be final and conclusive. 
    Id. at 411
    . Neither party argues these additional standards should apply or that they would compel a
    different result. And under any of the applicable standards, Sarepta has failed to establish standing
    to bring this action challenging the HCA’s rules.
    10
    No. 54870-4-II
    a favorable decision will likely—not merely speculatively—redress the injury. Patterson, 171
    Wn. App. at 259.
    The second requirement is referred to as the “zone of interests” test. Allan, 140 Wn.2d at
    327. “The zone of interest test limits judicial review of an agency action to litigants with a viable
    interest at stake, rather than individuals with only an attenuated interest in the agency action.” City
    of Burlington, 187 Wn. App. at 862. In order to satisfy the “zone of interests” test, the party
    seeking standing must demonstrate that “the Legislature intended the agency to protect the party's
    interests when taking the action at issue.” St. Joseph Hosp. and Health Care Ctr. v. Dep’t of
    Health, 
    125 Wn.2d 733
    , 739-40, 
    887 P.2d 891
     (1995); City of Burlington, 187 Wn. App. at 863.
    B.     SAREPTA’S STANDING—ZONE OF INTERESTS
    The HCA argues that Sarepta fails to establish standing because Sarepta has not met its
    burden to show that the zone of interests test is satisfied. Specifically, the HCA contends that the
    legislature did not intend to protect a drug manufacturer’s financial interests in establishing the
    administration of Washington’s Medicaid program. Sarepta argues that because it has entered a
    Medicaid Drug Rebate Agreement under the MDRP, its interest in having its drugs reimbursed by
    the HCA is established under the terms of the MDRP. We agree with the HCA.
    As an initial matter, the Washington legislature clearly did not intend to protect the interests
    of drug manufacturers when it directed the HCA to establish an evidence-based prescription drug
    program under RCW 70.14.050. The legislature directed the HCA to “take any necessary actions
    to control costs without reducing the quality of care when reimbursing for or purchasing drugs.”
    RCW 70.14.050(1). Based on the plain language of the statute, the legislature’s intent was for the
    HCA to balance controlling costs with ensuring quality of care. The legislature did not intend for
    11
    No. 54870-4-II
    the HCA to protect Sarepta’s financial interests when making rules to administer the prescription
    drug program. Therefore, Sarepta has failed to satisfy the zone of interests test under the
    Washington statutes. See St. Joseph Hosp., 
    125 Wn.2d at 739-40
    .
    However, Sarepta argues that its standing derives from the MDRP, not the Washington
    statutes. Sarepta contends that the MDRP guarantees coverage when a drug manufacturer enters
    into a rebate agreement under the terms of the MDRP. Because the HCA is responsible for
    ensuring the state Medicaid program complies with federal Medicaid requirements, Sarepta asserts
    that the HCA was required to protect Sarepta’s interests under the MDRP when administering its
    prescription drug program.
    Sarepta misinterprets the effect of an agreement under the MDRP and conflates coverage
    of drugs with reimbursement of drugs. And Sarepta’s argument fails to acknowledge Congress’s
    legislative intent when establishing the MDRP. Sarepta’s financial interests are no more protected
    under the MDRP than they are under RCW 70.14.050. Because Congress did not intend for
    prescription drug programs to protect the financial interests of drug manufacturers, Sarepta is not
    within the zone of interests protected by the MDRP.
    First, Sarepta’s argument fails to acknowledge Congress’s legislative intent when
    establishing the MDRP. The text of the MDRP does not contain an explicit statement of purpose
    or intent like that contained in RCW 70.14.050. Therefore, the plain language of the statute is
    ambiguous in establishing Congress’s intent in passing the legislation. However, the legislative
    history is not ambiguous. The house bill report clearly shows that Congress’s intent in establishing
    the MDRP was to control Medicaid costs by reducing the costs of prescription drugs. 1990
    U.S.C.C.A.N. 2017, 2108 (“The Committee believes that Medicaid, the means-tested entitlement
    12
    No. 54870-4-II
    program that purchases basic health care for the poor, should have the benefit of the same discounts
    on single source drugs that other large public and private purchasers enjoy.”). Congress further
    intended to ensure Medicaid patients have access to the same range of drugs as patients that do not
    require Medicaid. 1990 U.S.C.C.A.N. 2017, 2108-09. The legislative history of the MDRP does
    not establish Congress’s intent to protect the drug manufacturer’s financial interests when
    establishing the MDRP.
    Second, despite Congressional intent, Sarepta argues that agreements under the MDRP
    entitle Sarepta to reimbursement for its drugs, which creates a protected interest for drug
    companies who have agreements under the MDRP. Sarepta’s argument conflates the concepts of
    coverage and reimbursement under the MDRP. Furthermore, Sarepta’s argument misrepresents
    the effect of a rebate agreement under the MDRP.
    Sarepta’s argument is that because state prescription drug programs are required to cover
    all of a drug manufacturer’s prescription drugs, the state prescription drug program is required to
    pay for all covered drugs prescribed for its intended use. This is an incorrect reading of the MDRP.
    The MDRP does not specifically define the meaning of “covered” and the definition of a
    “covered outpatient drug” does not contain any language related to reimbursement or payment for
    a drug. See 42 U.S.C. § 1396r-8(k)(2). However, reading the MDRP as a whole shows there is a
    difference between coverage of a drug and reimbursement/payment for a drug. For example, 42
    U.S.C. § 1396 r-8(d)(5) references prior authorization as a condition of “coverage or payment,”
    indicating that there is a difference between coverage of a drug and payment for a drug. Sections
    of the MDRP also reference “upper payment limits” and “maximum allowable cost limitation”
    established by State programs, implying that there is a point at which the State would not be
    13
    No. 54870-4-II
    required to pay for covered drugs. See 42 U.S.C. § 1396r-8(e)(3) (“This section shall not supersede
    or affect provisions . . . relating to any maximum allowable cost limitation established by a State
    for payment by the State for covered outpatient drugs, and rebates shall be made under this section
    without regard to whether or not payment by the State for such drugs is subject to such a limitation
    or the amount of such a limitation.”); see also 42 U.S.C. § 1396r-8(e)(4), (e)(5).
    The language of the MDRP does not establish that coverage for prescription drugs requires
    payment for prescription drugs. The MDRP only establishes that the covered prescription drugs
    are eligible for reimbursement or payment under Medicaid programs. Therefore, Sarepta has
    incorrectly interpreted the MDRP to guarantee payment for prescription drugs; the MDRP only
    allows coverage for prescription drugs.
    Third, Sarepta argues that its agreement under the MDRP creates an interest that must be
    protected because drug manufacturers agree to provide rebates in exchange for a guarantee that
    that State Medicaid programs cover their drugs. As explained above, coverage is not the same as
    payment. And rebate agreements under the MDRP are not the equivalent of negotiated contracts
    as Sarepta implies.    Rebate agreements under the MDRP are a mandatory prerequisite for
    prescription drugs to be eligible for Medicaid coverage. 42 U.S.C. § 1396r-8(a)(1). In other words,
    to the extent that a rebate agreement is akin to a contract, drug manufacturers enter into rebate
    agreements in exchange for their drugs being eligible for Medicaid coverage, not to guarantee
    payment for their drugs.
    Because the MDRP only makes the drugs covered and does not guarantee drug
    manufacturers payment for their drugs under Medicaid, the MDRP does not establish that Sarepta
    has an interest that the HCA was required to protect when it established rules for the administration
    14
    No. 54870-4-II
    of its Medicaid prescription drug program. Therefore, Sarepta has failed to establish that the
    MDRP places Sarepta’s financial interests within the zone of interests required to be considered
    by the HCA.
    Sarepta’s MDRP agreement does not establish standing to petition for judicial review under
    the APA. Therefore, Sarepta has failed to establish standing under the APA to bring its petition
    for judicial review of the HCA’s application of its hierarchy of evidence rule in determining
    reimbursement for Exondys.
    CONCLUSION
    Sarepta does not have standing to petition for judicial review of HCA’s prior authorization
    rules under the APA because Sarepta has failed to satisfy the zone of interests requirement.
    Therefore, the superior court erred by denying the HCA’s motion to dismiss for lack of standing.
    Accordingly, we reverse the superior court’s order denying the HCA’s motion to dismiss for lack
    of standing and dismiss Sarepta’s appeal.
