    VICE CHIEF JUSTICE PELANDER authored the opinion of the Court, in
    which CHIEF JUSTICE BALES, and JUSTICES BRUTINEL, TIMMER, and
    BOLICK joined.
    VICE CHIEF JUSTICE PELANDER, opinion of the Court:
    ¶1             Under Arizona’s comparative fault regime, “[i]n assessing
    percentages of fault” in a personal injury action, “the trier of fact shall
    consider the fault of all persons who contributed to the alleged injury.”
    A.R.S. § 12-2506(B). In allocating fault, the trier may consider a nonparty’s
    negligence or fault if the defendant, pursuant to Arizona Rule of Civil
    Procedure 26(b)(5), gives notice that “a nonparty was wholly or partially at
    fault.” Id. In view of these statutory directives, we today hold that the
    common law “original tortfeasor rule” (“OTR”) does not preclude a
    defendant from alleging and proving, or the trier of fact from considering
    and finding, fault of a nonparty physician who treated the plaintiff for
    injuries allegedly sustained from the defendant’s tort.
    ¶2            We further hold that under the OTR, an actor who negligently
    causes an injury that reasonably necessitates medical treatment may also be
    liable for any enhanced harm proximately resulting from the actor’s
    2
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    negligence, including subsequent injury and related damages negligently
    but foreseeably caused by a medical provider. Any such liability, however,
    results not from automatically imputing the medical negligence to the
    original tortfeasor, but instead depends on the trier of fact’s assessment and
    allocation of fault between the parties and nonparties, in accordance with
    Arizona’s statutes.
    I.
    ¶3            In November 2010, a car driven by Courtney Cramer rear-
    ended a vehicle in which Tammy Munguia was a passenger. Munguia
    complained of headaches that same day and began chiropractic treatment
    a few days later. Because of persistent low back pain, Munguia had an MRI,
    which revealed several disc protrusions in her lumbar spine.
    ¶4            Approximately eight months after the accident, John
    Ehteshami, M.D., examined Munguia and recommended spinal fusion
    surgery to treat her back pain. In September 2011, Dr. Ehteshami performed
    that operation, which did not cure Munguia’s symptoms and might have
    exacerbated her condition.
    ¶5            After the unsuccessful surgery, Munguia filed this personal
    injury action against Cramer. At Cramer’s request, Zoran Maric, M.D.,
    conducted an independent medical examination and found no objective
    evidence that Munguia sustained any spinal injuries as a result of the car
    accident. Dr. Maric opined that the spinal fusion performed by Dr.
    Ehteshami was medically unnecessary and “effectively disabled” Munguia.
    ¶6             Based on that information, Cramer filed a notice naming Dr.
    Ehteshami as a nonparty at fault. See Ariz. R. Civ. P. 26(b)(5). Munguia
    moved for partial summary judgment to strike that notice, arguing that
    (1) the notice was untimely, and (2) under the OTR, Cramer, as the original
    tortfeasor, was liable for the foreseeable risks arising from her tort,
    including subsequent medical negligence. The trial court rejected the first
    argument but granted the motion based solely on the second ground.
    Relying on the Restatement (Second) of Torts § 457 (Am. Law Inst. 1965)
    (“Second Restatement § 457”) and some out-of-state cases holding that
    “adoption of comparative fault has not superseded” the OTR, the court
    ruled that Cramer “may not name Dr. Ehteshami as a non-party at fault,”
    3
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    but “may still dispute at trial whether Munguia reasonably sought medical
    care and/or reasonably selected her doctor.”
    ¶7            The court of appeals declined jurisdiction of Cramer’s special
    action. We granted review because the case presents an unsettled legal
    question that is of statewide interest and likely to recur. See Piner v. Superior
    Court, 
    192 Ariz. 182
    , 184 ¶ 7, 
    962 P.2d 909
    , 911 (1998) (granting review to
    address significant legal issue despite court of appeals having declined
    special action jurisdiction). We have jurisdiction under article 6, section 5(3)
    of the Arizona Constitution and A.R.S. § 12-120.24.
    II.
    ¶8           We review de novo the trial court’s grant of partial summary
    judgment. Weitz Co. v. Heth, 
    235 Ariz. 405
    , 409 ¶ 11, 
    333 P.3d 23
    , 27 (2014).
    Because the pertinent facts are undisputed, we must determine whether
    Munguia was entitled to judgment as a matter of law, precluding Cramer
    from naming Dr. Ehteshami as a nonparty at fault. See Ariz. R. Civ. P. 56(a).
    ¶9            Cramer argues that the trial court, by striking her notice,
    erroneously “took the issue of comparative fault from the jury,” in violation
    of A.R.S. § 12-2506. She also asserts that Second Restatement § 457, on
    which the trial court relied, “could never trump that controlling Arizona
    statute and case law” and, in any event, has been superseded by
    Restatement (Third) of Torts, Liability for Physical and Emotional Harm
    § 35 (Am. Law Inst. 2009) (“Third Restatement § 35”).
    ¶10           Munguia counters that Arizona courts have long embraced
    the OTR embodied in Second Restatement § 457 (as retained and broadened
    in Third Restatement § 35), a rule she characterizes as one of causation that
    was not displaced or abrogated by the Uniform Contribution Among
    Tortfeasors Act (“UCATA”). A.R.S. §§ 12-2501 through -2509. Under the
    OTR, Munguia asserts, Cramer “cannot escape or reduce her liability by
    claiming harm was caused by non-party Dr. Ehteshami,” but rather she is
    independently liable “for any and all enhanced harm proximately resulting
    from her actions” and “foreseeably caused by a successive tortfeasor.”
    ¶11          We agree with Cramer that UCATA applies and controls the
    outcome here. As first enacted in 1984, the Act allowed a tortfeasor who
    paid more than the percentage of damages attributed to it by the factfinder
    4
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    to seek contribution from co-tortfeasors. A.R.S. § 12–2501; Watts v. Medicis
    Pharm. Corp., 
    239 Ariz. 19
    , 26 ¶ 20, 
    365 P.3d 944
    , 951 (2016). The legislature
    amended the Act three years later by generally “eliminating plaintiffs’
    ability to recover jointly from any or all liable defendants.” Watts, 239 Ariz.
    at 26 ¶ 20, 365 P.3d at 951. With certain exceptions not applicable here, see
    § 12-2506(D), (F)(1), “the liability of each defendant for damages is several
    only.” § 12-2506(A). Thus, “Arizona’s pure comparative fault scheme
    protects defendants from bearing more than their fair share of liability for
    a plaintiff’s injuries under the harsh common-law rule of joint and several
    liability.” Watts, 239 Ariz. at 26 ¶ 20, 365 P.3d at 951 (citing State Farm Ins.
    Co. v. Premier Manufactured Sys., Inc., 
    217 Ariz. 222
    , 224–25 ¶¶ 8–12, 
    172 P.3d 410
    , 412–13 (2007)).
    ¶12           “UCATA requires apportionment of damages based on
    degrees of fault.” 
    Id.
     at 26 ¶ 22, 365 P.3d at 951. Under § 12-2506(A), “[e]ach
    defendant is liable only for the amount of damages allocated to that
    defendant in direct proportion to that defendant’s percentage of fault.”
    “Fault” is broadly defined as “an actionable breach of legal duty, act or
    omission proximately causing or contributing to injury or damages
    sustained by a person seeking recovery.” § 12-2506(F)(2). UCATA is thus
    based on the concept of fault, which necessarily presupposes a duty, breach
    of duty, and causation. Watts, 239 Ariz. at 26 ¶ 22, 365 P.3d at 951.
    ¶13           Under A.R.S. § 12-2506(B), the trier of fact assesses
    percentages of fault after considering the fault of all persons who
    contributed to the alleged injury. That mandate applies “regardless of
    whether the person was, or could have been, named as a party to the suit.”
    § 12-2506(B); see Dietz v. Gen. Elec. Co., 
    169 Ariz. 505
    , 509, 511, 
    821 P.2d 166
    ,
    170, 172 (1991) (holding that “[w]hen an employer negligently contributes
    to an employee’s injury, the joint tortfeasors may require the employer’s
    negligence to be considered for the assessment of fault under A.R.S. § 12-
    2506,” even though the employee, having received workers’ compensation
    benefits, could not sue the employer and would have to repay the employer
    from any third-party recovery).
    ¶14            UCATA thus contemplates and permits the naming of
    nonparties whose alleged fault the trier of fact may consider in
    apportioning liability. “Negligence or fault of a nonparty may be
    considered . . . if the defending party gives notice before trial, in accordance
    with requirements established by court rule, that a nonparty was wholly or
    5
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    partially at fault.” § 12-2506(B); see Ariz. R. Civ. P. 26(b)(5) (identifying
    procedural requirements for parties’ providing notice of nonparty at fault
    pursuant to § 12-2506(B)); Rosner v. Denim & Diamonds, Inc., 
    188 Ariz. 431
    ,
    433, 
    937 P.2d 353
    , 355 (App. 1996) (“Rule 26(b)(5) merely prescribes the
    method by which § 12-2506 is implemented and effectuated.”). 1 And under
    § 12-2506(C), “the relative degrees of fault of all defendants and
    nonparties[] shall be determined and apportioned as a whole at one time
    by the trier of fact.”
    ¶15             Our case law has consistently recognized and applied these
    principles. We have repeatedly held that under UCATA, the trier of fact
    must consider the fault of all parties and properly named nonparties in
    assessing and allocating percentages of fault. See, e.g., Premier Manufactured
    Sys., Inc., 217 Ariz. at 228 ¶ 30, 
    172 P.3d at 416
     (stating that § 12-2506(F)(2)’s
    “broad definition of fault” requires the trier of fact “to compare fault among
    all tortfeasors”); Piner, 
    192 Ariz. at
    188–89 ¶¶ 26–27, 
    962 P.2d at 915-16
    (holding that although UCATA “left intact the rule of indivisible injury,
    relieving the plaintiff of apportioning damage according to causal
    contribution,” § 12-2506 requires that “the factfinder [in an indivisible
    injury case] is to compute the total amount of damage sustained by the
    plaintiff and the percentage of fault of each tortfeasor”); Sanchez v. City of
    Tucson, 
    191 Ariz. 128
    , 133 ¶ 25, 
    953 P.2d 168
    , 173 (1998) (noting that under
    UCATA the state could name non-parties at fault and have the trier of fact
    1      The trial court rejected Munguia’s argument that Cramer’s notice of
    nonparty at fault should be stricken as untimely under Rule 26(b)(5).
    Munguia did not argue the timeliness issue in response to Cramer’s petition
    for special action in the court of appeals, in response to Cramer’s petition
    for review in this Court, or in any cross-petition for review here. Therefore,
    the issue was not preserved and is not before us, even though Munguia
    alternatively argued in her supplemental brief in this Court that Cramer’s
    notice of nonparty at fault was untimely. See State v. Ikirt, 
    160 Ariz. 113
    , 117,
    
    770 P.2d 1159
    , 1163 (1987) (failure to file a cross-petition for review of issue
    raised in but not decided by court of appeals “acts as a waiver”); cf. Dombey
    v. Phx. Newspapers, Inc., 
    150 Ariz. 476
    , 482, 
    724 P.2d 562
    , 568 (1986) (noting
    that generally a party waives an issue raised in neither the court of appeals
    nor in petition for review filed in this Court); Ariz. R. Civ. App. P. 23(f)(2).
    Nor do we address whether the medical malpractice requirements in A.R.S.
    §§ 12-2603 and -2604 apply to Cramer’s notice of nonparty at fault and, if
    so, whether the notice is compliant.
    6
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    apportion liability among them); Dietz, 
    169 Ariz. at 508, 510
    , 
    821 P.2d at 169, 171
     (observing that under UCATA, the trier of fact must “consider the fault
    of all persons who contributed to the alleged injury,” and each tortfeasor is
    “responsible for paying for his or her percentage of fault and no more”)
    (quoting § 12-2506(B)).
    ¶16             Munguia unpersuasively argues that § 12-2506(B) does not
    control because this case involves successive, not joint, tortfeasors, and
    Cramer is “severally liable for the full amount of damages” (including any
    that Dr. Ehteshami might have caused), but may seek contribution from
    him under A.R.S. § 12-2501. The argument is refuted by our case law. See
    Piner, 
    192 Ariz. at
    189 ¶ 30, 
    962 P.2d at 916
     (stating in case of successive
    tortfeasors and indivisible injury that “the jurors must be instructed to
    allocate fault in accordance with § 12-2506”); Dietz, 
    169 Ariz. at 510
    , 
    821 P.2d at 171
     (finding that § 12-2506 prevailed over § 12-2501 and noting that,
    “[w]ith a few specified exceptions, contribution will become virtually
    unnecessary in actions filed after the effective date of § 12-2506”). The cases
    on which Munguia relies are materially distinguishable because they were
    anchored in well-established common law doctrines that implicated the
    statutory exceptions to several liability in § 12-2506(D). See Young v. Beck,
    
    227 Ariz. 1
    , 5 ¶¶ 16-17, 
    251 P.3d 380
    , 384 (2011) (recognizing the family
    purpose doctrine as a “form of vicarious liability” that falls within the
    agency exception in § 12-2506(D)(2)); Wiggs v. City of Phx., 
    198 Ariz. 367
    , 371
    ¶¶ 13-14, 
    10 P.3d 625
    , 629 (2000) (same regarding the common-law, non-
    delegable duty doctrine, which UCATA did not abolish).
    ¶17           In striking Cramer’s notice of nonparty at fault, the trial court
    did not address Arizona’s statutory requirements or related case law and
    erred in preventing the trier of fact from considering any potential fault of
    Dr. Ehteshami. Neither the court’s ruling nor Munguia’s argument can be
    reconciled with UCATA’s clear directives. Section 12-2506(D) identifies
    various circumstances under which “a party is responsible for the fault of
    another person, or for payment of the proportionate share of another
    person.” But those exceptions do not apply here. And the statutes contain
    no exception to UCATA’s several-liability rule when (1) a medical
    provider’s post-accident services, even if medically necessary and
    foreseeable, are allegedly negligent and cause the claimant to sustain new
    or enhanced injury, or, more broadly, (2) when a non-party at fault is a
    medical practitioner. Cf. Dumas v. Louisiana, 
    828 So. 2d 530
    , 537 (La. 2002)
    7
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    (noting that state’s pure comparative fault statute “makes no exceptions for
    liability based on medical malpractice”).
    ¶18             Having named Dr. Ehteshami as a nonparty at fault, Cramer
    is entitled to have the trier of fact consider Dr. Ehteshami’s alleged
    negligence “[i]n assessing percentages of fault.” § 12-2506(B). The trier
    “shall . . . determine[] and apportion[] as a whole at one time” the relative
    degrees of fault of Cramer and Dr. Ehteshami. § 12-2506(C). As Cramer
    acknowledges, she bears the burden of proving any fault on Dr.
    Ehteshami’s part.
    III.
    ¶19         The trial court based its ruling on Second Restatement § 457,
    entitled “Additional Harm Resulting From Efforts to Mitigate Harm
    Caused by Negligence,” which sets forth the OTR:
    If the negligent actor is liable for another’s bodily injury, he is
    also subject to liability for any additional bodily harm
    resulting from normal efforts of third persons in rendering
    aid which the other’s injury reasonably requires, irrespective
    of whether such acts are done in a proper or a negligent
    manner.
    The comments to that section indicate that when a negligent actor causes
    an injury that may require medical services, it is reasonably foreseeable that
    such services could be performed negligently, thereby adding to the
    original injury. In such cases, the original tortfeasor “is responsible for any
    additional injury resulting from the other’s exposure” to the risk of
    negligently performed medical services. Id. cmt. b.
    ¶20           Our court of appeals has referred to and arguably relied on,
    but not expressly adopted, Second Restatement § 457. See Ritchie v. Krasner,
    
    221 Ariz. 288
    , 299 ¶ 29, 
    211 P.3d 1272
    , 1283 (App. 2009) (finding § 457
    “instructive” on whether substantial evidence supported jury’s
    determination that independent medical examiner’s negligence increased
    the risk of, and proximately caused, workers’ compensation claimant’s
    death); Barrett v. Harris, 
    207 Ariz. 374
    , 379 ¶¶ 17–18, 
    86 P.3d 954
    , 959 (App.
    2004) (stating that “[a]lthough § 457 can apply to successive acts of medical
    malpractice,” no evidence showed that doctor’s consultation advice

    Opinion of the Court
    proximately caused infant’s death, and therefore “§ 457 did not apply to
    impute liability” to the doctor); Transcon Lines v. Barnes, 
    17 Ariz. App. 428
    ,
    430 n.1, 434, 
    498 P.2d 502
    , 504 n.1, 508 (1972) (noting in dicta, without
    deciding, that § 457 supported original tortfeasors’ liability for enhanced
    damages (claimant’s later death)). But as Barrett noted, “[n]o Arizona
    opinion has applied [Second] Restatement § 457.”

    86 P.3d at
    959 n.4.
    ¶21            This Court has not addressed, let alone adopted, Second
    Restatement § 457.2 “In Arizona, if there is no statute or case law on a
    particular subject, we have traditionally followed the Restatement of
    Laws,” Martinez v. Woodmar IV Condos. Homeowners Ass’n, 
    189 Ariz. 206
    ,
    208, 
    941 P.2d 218
    , 220 (1997), and generally will embrace the Restatement if
    it prescribes “a sound and sensible rule,” Webster v. Culbertson, 
    158 Ariz. 159
    , 162, 
    761 P.2d 1063
    , 1066 (1988). Here, however, UCATA and our case
    law clearly permit Cramer’s notice of nonparty at fault and, assuming
    evidentiary support exists, require the trier of fact to consider Dr.
    Ehteshami’s alleged negligence in assessing and allocating fault and to
    determine liability. Thus, to the extent Second Restatement § 457 can be
    read to preclude those procedures and to support the trial court’s ruling, it
    is directly contrary to Arizona law and we reject it. See Ft. Lowell-NSS Ltd.
    P’ship v. Kelly, 
    166 Ariz. 96
    , 102, 
    800 P.2d 962
    , 968 (1990) (“Absent Arizona
    law to the contrary, this court will usually apply the law of the
    Restatement.”).
    ¶22             Based on UCATA, we likewise reject Munguia’s assertion that
    the OTR should apply to automatically hold the original tortfeasor severally
    liable for all damages she proximately caused “because the fault, if any, of
    the negligent medical care is imputed to the original tortfeasor and is
    subsumed within the original tortfeasor’s fault.” That argument cannot be
    squared with UCATA’s provisions defining “fault” and requiring the trier
    2       Inasmuch as Arizona courts have not adopted Second Restatement
    § 457 or any other form of the OTR, Munguia’s assertion that “UCATA did
    not clearly and plainly abrogate the [OTR]” misses the mark. And contrary
    to her argument, we find no indication that the legislature “intended to
    codify” the OTR when it enacted § 12-2501, the contribution statute, in 1984.
    Moreover, as stated, the trial court’s interpretation and application of § 457
    to strike Cramer’s notice of nonparty at fault is plainly inconsistent with
    § 12-2506.

    of fact to consider, determine, and apportion the fault of all parties and
    properly named nonparties. § 12-2506(B), (C), (F)(2). Although we agree
    with Munguia’s contention that the OTR is a rule of causation (treating the
    original tortfeasor as proximately causing certain later inflicted harm), not
    joint and several liability, that characterization does not alter our
    conclusion. UCATA displaced our prior common law under which
    multiple tortfeasors whose negligence proximately caused a particular
    injury would be jointly and severally liable. The OTR is a doctrine of
    causation and does not preclude applying UCATA. Cf. Larsen v. Nissan
    Motor Corp. in U.S.A., 
    194 Ariz. 142
    , 146 ¶ 10, 
    978 P.2d 119
    , 123 (App. 1998)
    (observing that “the causation element is factored in as ‘a necessary
    condition precedent to consideration of a person’s fault’ under [UCATA]”)
    (quoting Zuern v. Ford Motor Co., 
    188 Ariz. 486
    , 492, 
    937 P.2d 676
    , 682 (App.
    1996)).
    IV.
    ¶23          The Restatement (Second) of Torts has been updated and
    revised by the Restatement (Third) of Torts. As it relates to the OTR, the
    Third Restatement generally reiterates Second Restatement § 457. See Third
    Restatement § 35, cmt. a. Entitled “Enhanced Harm Due to Efforts to
    Render Medical or Other Aid,” Third Restatement § 35 provides:
    An actor whose tortious conduct is a factual cause of harm to
    another is subject to liability for any enhanced harm the other
    suffers due to the efforts of third persons to render aid
    reasonably required by the other’s injury, so long as the
    enhanced harm arises from a risk that inheres in the effort to
    render aid.
    See also 1 Dan B. Dobbs et al., The Law of Torts, § 211, at 740 (2d ed. 2011)
    (noting that the “original actor may be liable, for example, not only for the
    harm he directly causes, but also for the additional harm inflicted by . . .
    negligent medical treatment of [the first] injury,” citing cases and Third
    Restatement § 35).
    ¶24            The Third Restatement emphasizes that adoption of several-
    only liability statutes like UCATA does not require or imply any change to
    the OTR. Third Restatement § 35 cmt. d. As Comment (d) explains, this is
    because “[m]odern adoption of pure several liability limits the liability of
    10
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    each defendant liable for the same harm to that defendant’s comparative
    share of the harm.” Id. (emphasis added) (citing Restatement (Third) of
    Torts, Apportionment of Liability § 11). “Several liability, however, does
    not provide rules about when defendants are liable for harm that they
    caused.” Id. (emphasis added). Instead, as Comment (d) clarifies, when
    “the [state’s] governing law imposes several liability, each of the defendants
    is held liable for the amount of damages reflecting the enhanced harm
    discounted by the comparative share of responsibility assigned by the
    factfinder to that defendant.” Id. (emphasis added).
    ¶25             Thus, the OTR, now set forth in Third Restatement § 35, can
    be read in conjunction with the governing law of the state. When the state’s
    law generally provides for several-only liability, as does UCATA, the OTR
    provides guidelines only regarding when a defendant may be subject to
    liability for future, enhanced harm that stems from the original negligent
    conduct—e.g., when the original tortfeasor’s conduct created a reasonably
    foreseeable risk that future medical services may be necessary and that
    those services may be performed negligently. But the Third Restatement
    makes clear that the OTR yields to a state’s law governing the
    apportionment of fault (and consequently, damages) based on the
    factfinder’s determination of each potential tortfeasor’s comparative share
    of responsibility. See 2 Dobbs, § 494, at 93 (noting that “under the traditional
    rule, a tortfeasor who causes injury is jointly and severally liable for any
    aggravation caused by a negligent health care provider, but under the
    several liability regime, the initial tortfeasor is liable only for his
    comparative fault share”); see also Dumas, 
    828 So. 2d at 537
     (holding that
    under state’s pure comparative fault statutes, the fault of both the
    defendant/tortfeasor and nonparty medical providers who treated the
    original injury “should be determined” and each tortfeasor “will be liable
    only for his portion of fault”). These fault-related issues, including
    causation, generally are questions of fact for a jury to resolve. See § 12-
    2506(B), (C), (F)(2); Third Restatement § 35, illus. 4; see also Gipson v. Kasey,
    
    214 Ariz. 141
    , 143 ¶ 9, 
    150 P.3d 228
    , 230 (2007).
    ¶26           In sum, we harmonize the common law doctrine with
    Arizona’s statutory scheme by adopting the OTR set forth in the Third
    Restatement § 35, but only to the extent it does not conflict with UCATA.
    Doing so is consistent with our embracing the Restatement (Third) of Torts,
    Liability for Physical and Emotional Harm § 32, the corollary to Third
    Restatement § 35, in Espinoza v. Schulenberg, 
    212 Ariz. 215
    , 217 ¶¶ 7-9, 129
    11
    CRAMER V. STARR (MUNGUIA/BEJARANO)
    Opinion of the Court
    P.3d 937, 939 (2006) (adopting the “rescue doctrine” set forth in Third
    Restatement § 32 and noting that “injury to a rescuer is a foreseeable result
    of the original negligence”).
    ¶27            Subject to UCATA, the OTR can serve a useful purpose in
    cases like this. As stated earlier, the rule cannot be used to automatically
    impute to the original tortfeasor the subsequent negligence of a medical
    provider or other person who renders aid reasonably required by the
    original tortfeasor’s act. But because UCATA defines fault as an actionable
    breach of duty that proximately caused the plaintiff’s injury, § 12-
    2506(F)(2), plaintiffs remain free to argue under Third Restatement § 35 that
    an original tortfeasor proximately caused subsequent, enhanced injury and
    shares all or at least some responsibility for that injury. See Third
    Restatement § 35, cmt. d (noting that the “subsequent negligence of one
    rendering assistance to an injured person is not a superseding cause of any
    enhanced harm, thereby including such harm within the initial tortfeasor’s
    scope of liability”).
    ¶28          UCATA does not immunize or shield Cramer from liability
    for the enhanced harm allegedly caused by Dr. Ehteshami’s negligence. If
    Munguia shows that the conditions of Third Restatement § 35 are met,
    Cramer will have proximately caused the enhanced harm, and her liability
    for such harm will be determined, consistent with UCATA, by the jury’s
    assessment of comparative fault. See Third Restatement § 35.
    V.
    ¶29           The trial court erred in striking Cramer’s notice of nonparty
    at fault based on Second Restatement § 457. We reverse that order and
    remand the case to the trial court for further proceedings consistent with
    this opinion.
