    JUSTICE TIMMER, opinion of the Court:
    ¶1           Medicare Part C, 42 U.S.C. §§ 1395w-21 et seq., permits
    enrollees to obtain Medicare-covered healthcare services from private
    healthcare organizations and their third-party contractors. The Employee
    Retirement Income Security Act (“ERISA”), 29 U.S.C. §§ 1001 et seq.,
    regulates health plans offered by private employers to employees. We
    today hold that the administrative appeals process provided under the
    Medicare Act preempts arbitration of Medicare-related coverage disputes
    between private healthcare administrators and providers, even though
    arbitration would otherwise be required by the parties’ contracts and the
    Federal Arbitration Act (“FAA”), 9 U.S.C. §§ 1 et seq. We remand to the
    court of appeals to decide whether ERISA similarly preempts arbitration of
    ERISA-related coverage disputes.
    I. BACKGROUND
    ¶2           Congress passed the Medicare Act in 1965 to provide a federal
    health insurance program for qualified enrollees, most of whom are either
    ∗Chief Justice Scott Bales and Justice Clint Bolick recused themselves from
    this case. Pursuant to article 6, section 3 of the Arizona Constitution, the
    Honorable Rebecca White Berch, retired Justice, and the Honorable Garye
    L. Vásquez, Judge of the Arizona Court of Appeals, Division Two, were
    designated to sit in this matter.

    Opinion of the Court
    elderly or disabled. 42 U.S.C. §§ 1395 et seq. For many years, enrollees
    could obtain healthcare benefits only through Parts A and B of the Act,
    which is administered by the Centers for Medicare and Medicaid Services
    (“CMS”), a division of the Department of Health and Human Services
    (“HHS”). See Douglas v. Indep. Living Ctr. of S. Cal., Inc., 
    132 S. Ct. 1204
    , 1207-
    08 (2012).
    ¶3            In 1997, Congress enacted Part C, commonly known as the
    Medicare Advantage Program, to permit enrollees to obtain Part A and Part
    B coverage through private organizations, known as Medicare Advantage
    Organizations (“MA Organization” or “Organization”). 42 U.S.C.
    §§ 1395w-21, 1395w-27. CMS contracts with MA Organizations through a
    bidding process. 
    Id. § 1395w-24(A).
    Among other things, Organizations
    agree to comply with all Medicare laws, CMS rules, and federal coverage
    guidelines. 
    Id., § 1395y(a)(1)(A);
    42 C.F.R. § 422.101(a), (b)(1)-(3), (c). MA
    Organizations offer Medicare benefits, not private insurance. Cf. Pagarigan
    v. Superior Court, 
    126 Cal. Rptr. 2d 124
    , 134 (Ct. App. 2002) (noting that the
    relationship between MA Organizations and Part C enrollees is “not
    between an insurer and its policyholder, but rather, between Medicare . . .
    and Medicare beneficiaries”).
    ¶4           CMS pays an MA Organization a fixed monthly “capitation”
    fee for each Medicare beneficiary served by the Organization. 42 U.S.C.
    § 1395w-23. The Organization thereafter assumes the financial risk of
    providing health care services to those enrollees. 
    Id. § 1395w-25(b).
    MA
    Organizations can either provide services directly or contract with third-
    party healthcare providers to provide services. 42 C.F.R. §§ 422.100(a),
    422.202.
    ¶5            Petitioners Maricopa Integrated Health System (“MIHS”) and
    Aurora Behavioral Health Care – Tempe and Aurora Behavioral Health
    System, LLC (“Aurora”) (collectively, “Providers”) operate acute inpatient
    psychiatric hospitals. They entered into Facility Participation Agreements
    (“Agreements”) with respondent United Behavioral Health, Inc. (“UBH”),
    an MA Organization that issues and administers various types of health
    insurance plans, including Medicare Advantage plans and ERISA-
    regulated plans. MIHS and Aurora provide mental health and substance
    abuse treatment services to Medicare enrollees enrolled with UBH (“MA
    3
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    Plan Members”). Aurora also provides these services to members of
    ERISA-regulated plans administered by UBH (“ERISA Plan Members”).
    ¶6           The Agreements require MIHS and Aurora to obtain
    authorization from UBH before providing healthcare services to MA Plan
    Members and ERISA Plan Members. Providers must accept UBH’s
    payment for services as “payment in full” for services rendered to enrollees
    and cannot collect from them for unpaid services deemed medically
    unnecessary by UBH, unless enrollees agree to pay for these services.
    ¶7            The dispute in these cases concerns whether continued
    inpatient treatment by Providers was medically necessary, and therefore
    compensable, for several MA Plan Members and ERISA Plan Members
    initially hospitalized for mental health evaluations or treatment. UBH
    denied authorization for extended inpatient care as not medically
    necessary. Providers nonetheless continued providing inpatient care and
    sought reimbursement, which UBH denied.
    ¶8             Providers demanded arbitration with the American
    Arbitration Association pursuant to arbitration provisions in the
    Agreements, which are governed by the FAA. UBH filed separate lawsuits
    against MIHS and Aurora to stay the arbitration proceedings and determine
    arbitrability, with conflicting results. In the case against MIHS, the trial
    court found that the dispute was subject to arbitration and refused to stay
    the arbitration proceedings. In the case against Aurora, the court stayed the
    arbitration proceedings, ruling that the dispute concerned coverage and
    must be resolved through Medicare and ERISA administrative procedures.
    ¶9           The court of appeals consolidated the cases for purposes of
    appeal. It held that although the FAA presumptively favors arbitration,
    Congress overrode this presumption in the Medicare context by adopting
    an extensive administrative appeals process to resolve coverage disputes.
    United Behavioral Health v. Maricopa Integrated Health System, 
    237 Ariz. 559
    ,
    563, 565 ¶¶ 13, 24, 
    354 P.3d 1118
    , 1122, 1124 (App. 2015). The court
    determined that Providers’ claims are coverage disputes that turn on
    construction of Medicare benefit plans and applicable Medicare standards.
    
    Id. at 567
    ¶¶ 
    33–34, 354 P.3d at 1126
    . It therefore concluded that
    administrative review is Providers’ exclusive remedy, making the disputes
    4
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    concerning MA Plan Members nonarbitrable. 
    Id. ¶ 35;
    id. at 565 
    24, 354 P.3d at 1124
    .
    ¶10           The court of appeals did not decide whether ERISA claims are
    subject to arbitration. 
    Id. at 567
    ¶¶ 36, 
    40, 354 P.3d at 1126
    . The record was
    unclear whether Aurora has standing to assert ERISA claims, so the court
    remanded for the trial court to make that determination. 
    Id. at ¶
    40.
    ¶11            We granted Providers’ petition for review because it presents
    issues of statewide importance. We have jurisdiction pursuant to article 6,
    section 5 of the Arizona Constitution and A.R.S. § 12-120.24.
    II. DISCUSSION
    A. Scope of the arbitration provisions
    ¶12           The arbitration provisions in the Agreements are sufficiently
    broad to encompass the disputes here. They require the parties to arbitrate
    disputes “about their business relationship” (MIHS Agreement) and
    “arising out of their business relationship” (Aurora Agreement). Although
    the Agreements do not explicitly define “business relationship,” they
    implicitly do so by setting forth the terms and conditions under which
    Providers participate in UBH’s networks. Because Providers’ entitlement
    to payment for unauthorized services concerns the terms and conditions of
    the parties’ relationship, the arbitration provisions, unless preempted,
    apply to these disputes.
    B. Preemption
    ¶13            The Agreements provide that because they affect interstate
    commerce, the FAA applies. The FAA establishes “a liberal federal policy
    favoring arbitration agreements” and requires courts to enforce these
    agreements “unless the FAA’s mandate has been overridden by a contrary
    congressional command.” CompuCredit Corp. v. Greenwood, 
    132 S. Ct. 665
    ,
    669 (2012). Contrary to Providers’ argument, this “command” does not
    have to be expressly stated. Congressional intent may be deduced from the
    statute’s text, history, or “an inherent conflict between arbitration and the
    statute’s underlying purposes.” Shearson/Am. Express, Inc. v. McMahon, 
    482 U.S. 220
    , 227 (1987).
    5
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    ¶14           UBH contends that Congress provided exclusive procedures
    in the Medicare Act and in ERISA for resolving coverage disputes that
    preempt arbitration here. UBH, as the party resisting arbitration, bears the
    burden to prove preemption. See 
    CompuCredit, 132 S. Ct. at 672
    n.4.
    Whether arbitration is preempted is a question of law we decide de novo.
    See Hutto v. Francisco, 
    210 Ariz. 88
    , 90 ¶ 7, 
    107 P.3d 934
    , 936 (App. 2005).
    1. The Medicare Act
    ¶15            Congress has decreed that all claims “arising under” the
    Medicare Act must be resolved through HHS administrative review
    procedures. See Heckler v. Ringer, 
    466 U.S. 611
    , 614–15 (1984) (citing 42
    U.S.C. § 405(g)). A claim arises under the Medicare Act if “both the
    standing and the substantive basis for the presentation” of the claim is the
    Medicare Act or if the claim is “inextricably intertwined” with a claim for
    Medicare benefits. 
    Id. at 614–15.
    Funneling such claims through the Act’s
    administrative procedures promotes uniformity and consistency in
    administering Medicare. Cf. Weinberger v. Salfi, 
    422 U.S. 749
    , 765 (1975)
    (“Exhaustion is generally required as a matter of preventing premature
    interference with agency processes, so that the agency may function
    efficiently and so that it may have an opportunity to correct its own errors,
    to afford the parties and the courts the benefit of its experience and
    expertise, and to compile a record which is adequate for judicial review.”).
    If a claim is “wholly collateral” to the Medicare Act’s review provisions and
    outside HHS’s expertise, it is not subject to administrative review. See
    Thunder Basin Coal Co. v. Reich, 
    510 U.S. 200
    , 212 (1994) (citing 
    Heckler, 466 U.S. at 618
    ).
    ¶16            Providers’ claims are based not on the Medicare Act but on
    state contract law. Thus, we consider (1) whether the claims are inextricably
    intertwined with claims for Medicare benefits, as UBH argues, or instead
    are wholly collateral to the Medicare Act, as Providers contend, and (2) if
    inextricably intertwined, whether the Act provides administrative review
    procedures for disputes between an MA Organization and its Providers
    that do not directly involve enrollees.
    (a) Are Providers’ claims inextricably intertwined with claims for
    Medicare benefits?
    6
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    ¶17            Providers rely on cases from other jurisdictions to argue that
    the dispute here concerns a “wholly collateral” payment claim for which no
    administrative review exists. RenCare, Ltd. v. Humana Health Plan of Tex.,
    Inc., 
    395 F.3d 555
    (5th Cir. 2004), is representative of these cases. The issue
    there was whether RenCare, a provider, was required to exhaust
    administrative remedies before suing Humana, an MA Organization, to
    recover payment for kidney dialysis services provided to Humana
    enrollees. 1 
    Id. at 556–57.
    RenCare had waived the right to seek
    reimbursement from Humana enrollees, making RenCare’s sole remedy to
    recover payment from Humana. 
    Id. at 558.
    The Fifth Circuit found that
    RenCare’s claim was not inextricably intertwined with a claim for Medicare
    benefits because Humana had approved the services for which RenCare
    sought payment, no Humana enrollee sought benefits or was at risk of
    paying for services, and the government had no financial stake in the
    outcome. 
    Id. The court
    concluded that “[w]ith neither [Humana enrollees]
    nor the government having any financial interest in the resolution of this
    dispute, RenCare’s claims are not intertwined, much less ‘inextricably
    intertwined,’ with a claim for Medicare benefits.” 
    Id. at 559;
    see also Christus
    Health Gulf Coast v. Aetna, Inc., 
    237 S.W.3d 338
    , 344 (Tex. 2007) (concluding
    that hospitals did not need to exhaust administrative remedies to assert a
    claim against an MA Organization that concerned payment for
    indisputably covered services).
    ¶18           Providers’ claims are distinguishable from the payment
    disputes in RenCare and Christus Health. Unlike the MA Organizations in
    those cases, UBH did not refuse to pay for covered services; it disputed that
    the extended services at issue were medically necessary and thus covered.
    These are coverage disputes that cannot be resolved by applying the
    Agreements’ payment provisions. Cf. 42 C.F.R. § 422.566 (providing that an
    MA Organization’s refusal to provide medical services to an enrollee is an
    “organization determination” governed by the Act); Lone Star OB/GYN
    Assocs. v. AETNA Health Inc., 
    579 F.3d 525
    , 531 (5th Cir. 2009) (holding that
    a coverage claim includes a determination of what benefits are covered
    1       When RenCare was decided, Medicare Part C referred to
    “Medicare+Choice plans.” In 2003, Congress renamed those plans
    “Medicare Advantage plans.”     See Medicare Prescription Drug,
    Improvement, and Modernization Act, Pub. L. No. 108-173, § 201 (a)-(c)
    (2003).
    7
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    under the terms of a plan). Resolution turns on whether UBH correctly
    applied Medicare standards to determine that continued in-patient care for
    the MA Plan Members was not covered—a matter inextricably intertwined
    with a claim for benefits and falling within HHS’s expertise. Cf. Cmty.
    Health Ctr. v. Wilson-Coker, 
    311 F.3d 132
    , 134 (2d Cir. 2002) (“Medicare . . . is
    administered, for the most part, by intermediaries, who must apply a
    uniform set of standards established by federal law . . . .” (internal citation
    omitted)); Ex parte Blue Cross and Blue Shield of Ala., 
    90 So. 3d 158
    , 167 (Ala.
    2012) (distinguishing RenCare because the provider’s claims against the MA
    Organization were not based exclusively on the parties’ payment plan, but
    instead involved questions of coverage and compliance with the Medicare
    Act that had affected enrollees and could affect future enrollees).
    ¶19          We conclude that Providers’ claims are inextricably
    intertwined with claims for Medicare benefits and therefore arise from the
    Medicare Act.
    (b) Are Medicare administrative review procedures available to
    Providers?
    ¶20           Providers also rely on RenCare and Christus Health to argue
    that the Medicare Act’s administrative procedures are unavailable to them,
    and therefore the Act cannot preempt arbitration. The RenCare court
    concluded that the Act’s administrative review process “focuses on
    enrollees, not health care providers, and is designed to protect enrollees’
    rights to Medicare 
    benefits.” 395 F.3d at 559
    . If the enrollee has no further
    obligation to pay for furnished services, the court ruled, “a determination
    regarding these services is not subject to appeal.” 
    Id. (quoting 42
    C.F.R.
    § 422.562(c)(2)). No enrollee had requested an organization determination
    or appealed from one, 
    id., and no
    Humana enrollee had been denied a
    covered service or was required to pay for a service, 
    id. at 559–60.
    The court
    therefore found that Humana’s refusal to pay RenCare was not an
    organization determination that could be appealed through the Act’s
    mandatory administrative procedures. 
    Id. at 560;
    see also Christus 
    Health, 237 S.W.3d at 343
    (relying on RenCare to conclude that Medicare’s
    administrative procedures are not applicable to a medical provider’s
    contractual claim for payment from MA Organization for provided
    services).
    8
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    ¶21             Although the Act’s administrative procedures focus on
    enrollees’ interests, they also apply to contract providers in a dispute with
    an MA Organization when that dispute, at bottom, challenges an
    organization determination that denied services as medically unnecessary.
    “Any provider that furnishes, or intends to furnish, services to the enrollee”
    can request an organization determination, and any provider “who has
    furnished a service to the enrollee and formally agreed to waive any right
    to payment from the enrollee for that service” or that has “an appealable
    interest” is a party to the organization determination with full appeal rights.
    42 C.F.R. §§ 422.566(c)(ii), 422.574(b), (d), 422.578—.626; see also
    Establishment of the Medicare+Choice Program, 63 Fed. Reg. 34968, 35026 (Jun.
    26, 1998) (interpreting federal law to permit certain providers to be parties
    to organization determinations and to exercise appeal rights). Providers
    waived their rights to payment from enrollees in the Agreements and
    provided uncompensated services to enrollees. Under § 422.574(b) and (d),
    therefore, Providers were parties to the organization determination with
    full appeal rights.
    ¶22            Relying on 42 C.F.R. § 422.562(c)(2), the court in RenCare
    concluded that appeal rights are extinguished if an enrollee has no interest
    in the 
    outcome. 395 F.3d at 559
    . That regulation provides that “[i]f an
    enrollee has no further liability to pay for services that were furnished by
    an MA organization, a determination regarding these services is not subject
    to appeal.” We understand this provision as applying only to an enrollee’s
    appeal rights. It is included among general provisions addressing an MA
    Organization’s responsibilities and an enrollee’s rights; it does not focus on
    contract providers. And although it makes sense to disallow an enrollee’s
    appeal when that enrollee has no financial interest at stake, it does not
    follow that a contract provider who remains unpaid for services rendered
    should be denied appeal rights merely because the enrollee bears no
    liability. Most importantly, if § 422.562(c)(2) applies to extinguish a contract
    provider’s administrative appeal rights, the provision would conflict with
    regulations making a contract provider a party to an organization
    determination with full appeal rights when that provider has waived the
    right to payment from the enrollee. See 42 C.F.R. §§ 422.574(b), .578—.626;
    see also Nitro-Lift Techs., L.L.C. v. Howard, 
    133 S. Ct. 500
    , 504 (2012) (noting
    the time-honored interpretive principle that a specific statute governs a
    general one). The provisions are harmonized by interpreting § 422.562(c)(2)
    as applying only to an enrollee’s appeal rights.
    9
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    ¶23            We are also persuaded by policy considerations to conclude
    that the Act’s mandatory administrative procedures apply to Providers.
    Although neither the enrollees nor the government has a direct financial
    stake in this dispute, HHS directs and controls how MA Organizations
    administer benefits, and it therefore has an interest in developing the law
    on what is “medically necessary.” 2 See 42 C.F.R. §§ 422.1 et seq.; Shalala v.
    Ill. Council on Long Term Care, Inc., 
    529 U.S. 1
    , 12–13 (2000) (noting that
    channeling Medicare benefit coverage claims to HHS assures that the
    agency has a greater opportunity to apply, interpret, or revise its own
    policies and regulations); 
    Heckler, 466 U.S. at 605
    (“The Medicare Act
    authorizes the Secretary to determine what claims are covered by the Act
    ‘in accordance with the regulations prescribed by him.’”). If contract
    providers are precluded from pursuing administrative review of adverse
    coverage decisions, these matters will be resolved in arbitration (assuming
    it is either required or selected) or in state or federal courts. In these
    scenarios, HHS would be prevented from applying its expertise to coverage
    issues, thereby risking inconsistent results and an uneven development of
    the law.
    ¶24           Providers also argue that we should defer to CMS’s view that
    the Act’s administrative procedures do not apply to resolve disputes
    between contract providers and MA Organizations. (UBH, in contrast,
    maintains that contract providers can challenge organization
    determinations through the Act’s administrative review procedures.)
    Providers cite the Medicare Managed Care Manual, Chapter 13, § 70.1,
    which states, without explanation, that non-contract providers can be
    parties to an organization determination and have appeal rights but that
    “contract providers do not have appeal rights.” And in other cases, CMS’s
    designee has refused to consider an appeal involving a request by a contract
    provider for payment from an MA Organization, contending that only non-
    2       In 2006, Congress amended the Medicare Act Part C to provide that
    an MA Organization’s costs directly affect the Organization’s bid for a CMS
    contract the next year, which in turn impacts the government’s capitation
    payment amounts. See 42 U.S.C. § 1395w-24(b). If Providers prevail in this
    case and UBH is required to reimburse them for unpaid services, the
    government’s capitation rates for the next year will increase. Thus, unlike
    the situation in RenCare, the government here has an indirect financial stake
    in Providers’ claims.
    10
    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    contract providers have appeal rights. These positions are accurate
    regarding pure payment disputes that do not involve coverage issues
    between contract providers and MA Organizations. But they conflict with
    the regulations if the payment dispute concerns an organization
    determination regarding coverage, see supra ¶ 21, and do not persuade us
    to reach a different result. Cf. Cent. Laborers’ Pension Fund v. Heinz, 
    541 U.S. 739
    , 748 (2004) (“[N]either an unreasoned statement in the manual nor
    allegedly longstanding agency practice can trump a formal regulation with
    the procedural history necessary to take on the force of law.”).
    ¶25            Finally, Providers argue that UBH admitted that arbitration
    was available to resolve the disputes here. UBH denied benefit coverage
    for a patient after completing an internal appeal process. (The record does
    not show whether the patient was an MA Plan Member.) In a letter to MIHS
    communicating this decision, UBH enclosed an informational form
    concerning a provider’s rights that stated: “Is arbitration available? Yes,
    you may seek arbitration to address disputes not resolved after completion
    of the formal Provider Dispute process, as described in your contract with
    us and/or applicable state law.” It is unclear whether this provision applies
    to coverage disputes. The UBH provider manual states that the “Provider
    Dispute Resolution process” applies to payment disputes “regulated by the
    Agreement, rather than the Member’s Benefit Plan.” Even so, the above-
    quoted language is, at most, “what Wigmore calls a ‘quasi admission,’
    which is ‘nothing but an item of evidence’ and ‘is therefore not in any sense
    final or conclusive.’” Reed v. Hinderland, 
    135 Ariz. 213
    , 216, 
    660 P.2d 464
    , 467
    (1983) (quoting 4 Wigmore, Evidence § 1059 at 27 (Chadbourn rev. 1972)).
    ¶26           We conclude that Providers can avail themselves of the
    Medicare Act’s administrative review procedures. Providers must present
    their claims to HHS. 3 If HHS refuses to allow Providers to pursue these
    remedies on the basis that they do not apply to contract providers, this
    would foreclose the Providers’ ability to use the Act’s administrative
    review procedures, and Providers could then exercise their arbitration
    3      At oral argument before this Court, UBH acknowledged that
    Providers have administrative appeal rights but suggested that appeal of
    the claims here may be time-barred. We do not address the time-bar issue
    or whether UBH would be estopped from asserting that defense, as these
    issues have not been briefed and are not before us.

    rights. Cf. 
    Shalala, 529 U.S. at 19
    (stating that there is no requirement to
    channel review through the agency if it would “mean no review at all”);
    
    Heckler, 466 U.S. at 617
    (explaining that presentment of claim for benefits to
    HHS is nonwaivable but HHS can waive full pursuit of administrative
    remedies); Koerpel v. Heckler, 
    797 F.2d 858
    , 862 (10th Cir. 1986) (noting that
    the exhaustion of administrative remedies requirement can be excused “if
    exhaustion would be futile.”).
    2. ERISA
    ¶27           Providers argue that the court of appeals misapplied the FAA
    by concluding that whether Aurora’s claims concerning ERISA Plan
    Members can be arbitrated requires a determination that Aurora has
    standing to assert these claims. UBH responds that requiring the trial court
    to determine standing is permissible as it would not involve the merits of
    an arbitrable dispute.
    ¶28            When asked to decide whether a dispute is subject to
    arbitration governed by the FAA, a court is limited to deciding whether an
    arbitration agreement exists and whether it encompasses the dispute. See
    Chiron Corp. v. Ortho Diagnostic Sys., Inc., 
    207 F.3d 1126
    , 1130 (9th Cir. 2000).
    It must carefully avoid deciding the merits of an arbitrable claim or any
    defenses to it. See Republic of Nicaragua v. Standard Fruit Co., 
    937 F.2d 469
    ,
    478 (9th Cir. 1991) (“Our role is strictly limited to determining arbitrability
    and enforcing agreements to arbitrate, leaving the merits of the claim and
    any defenses to the arbitrator.”).
    ¶29            To decide whether Aurora’s ERISA-related claim is arbitrable,
    the court of appeals was tasked with deciding whether ERISA preempted
    arbitration through a “contrary congressional command.” See 
    CompuCredit, 132 S. Ct. at 669
    . Whether Aurora has standing to pursue its claim has no
    bearing on whether Congress intended to preempt arbitration for ERISA-
    related claims. The standing issue, and any other defenses UBH might have
    to Aurora’s claim, must be left to the arbitrator if the claim is subject to
    arbitration. Republic of 
    Nicaragua, 937 F.2d at 478
    . The court must assume
    that Aurora has asserted a viable claim and determine whether ERISA
    provides mandatory, exclusive procedures for adjudicating that claim. We
    remand to the court of appeals for this purpose.

    UNITED BEHAVIORAL HEALTH V. MARICOPA
    UNITED BEHAVIORAL HEALTH V. AURORA
    Opinion of the Court
    C. Request for attorney fees
    ¶30           Providers request an award of attorney fees pursuant to
    A.R.S. § 12-341.01. Because Providers are not the successful parties, we
    decline the request. If Aurora is ultimately successful before the court of
    appeals regarding the ERISA-related claims, it may renew its request before
    that court.
    III. CONCLUSION
    ¶31           Providers’ coverage claims are inextricably intertwined with
    claims for Medicare benefits, and they therefore are subject to the Medicare
    Act. The Act provides mandatory administrative review procedures for
    these disputes, which preempt arbitration. The trial court in Aurora’s case
    correctly stayed arbitration of the Medicare-related claims; the trial court in
    MIHS’s case incorrectly refused to stay the arbitration.
    ¶32            The court of appeals erred by deciding that whether Aurora’s
    ERISA-related claims are arbitrable depends on whether Aurora has
    standing to assert this claim. The court should decide on remand whether
    this claim is arbitrable without considering the standing issue or whether
    any valid defenses to the claim exist.
    ¶33           We vacate the court of appeals’ opinion and remand for
    further proceedings on Aurora’s claims concerning ERISA Plan Members.
    We affirm the trial court judgment in the Aurora lawsuit with respect to
    Providers’ claims concerning the MA Plan Members. We reverse the trial
    court judgment in the MIHS lawsuit and remand for entry of judgment
    staying arbitration proceedings.
