    Before: SRINIVASAN , Chief Judge, GARLAND and
    MILLETT, Circuit Judges.
    Opinion for the Court filed by Chief Judge SRINIVASAN .
    SRINIVASAN, Chief Judge: Many hospitals provide
    outpatient care at off-site facilities known as “off-campus
    provider-based departments,” or PBDs. Certain services
    offered by hospitals at off-campus PBDs, such as routine clinic
    visits, can also be provided by independent physician practices
    unaffiliated with a hospital. Although off-campus PBDs and
    independent physician practices can offer the same service,
    Medicare until recently reimbursed those providers at different
    rates: because off-campus PBDs are considered hospitals for
    regulatory purposes, they were paid a higher rate applicable to
    hospitals instead of a lower rate applicable to physician
    practices. The result was that, for the same outpatient service,
    off-campus PBDs obtained up to twice as much per patient in
    Medicare reimbursements as did physician practices.
    The Department of Health and Human Services
    determined that the payment differential gave rise to an
    economic incentive that induced unnecessary growth in the
    volume of outpatient care provided at off-campus PBDs. HHS
    thus reduced the rate it paid hospitals for the most common off-
    campus PBD service, “patient evaluation and management,” to
    3
    equal the rate paid to physician practices for that service. HHS
    justified that reimbursement cut as an exercise of its statutory
    authority to adopt “method[s] for controlling unnecessary
    increases in the volume” of covered outpatient services. 42
    U.S.C. § 1395l(t)(2)(F).
    A group of hospitals brought these consolidated actions,
    claiming that HHS’s rate reduction for off-campus PBDs falls
    outside of the agency’s statutory authority. The district court
    agreed and set aside the regulation implementing the rate
    reduction. Because we conclude that the regulation rests on a
    reasonable interpretation of HHS’s statutory authority to adopt
    volume-control methods, we now reverse.
    I.
    A.
    Medicare Part B health insurance covers outpatient
    hospital care, including same-day surgery, preventive and
    screening services, and physician visits. See 42 U.S.C.
    §§ 1395j, 1395k. The Department of Health and Human
    Services (HHS) sets the rates at which Medicare will reimburse
    hospitals for providing such services according to an intricate
    statutory system known as the Outpatient Prospective Payment
    System (OPPS). See 42 U.S.C. § 1395l(t).
    Under the OPPS, hospitals are not reimbursed for the
    actual costs incurred in providing care. Instead, to help control
    Medicare expenditures, the statute calls for HHS to set
    predetermined payment amounts for each covered outpatient
    service. See H.R. Rep. No. 106-436, at 33 (1999). Hospitals
    then receive that amount for every instance in which they
    provide the service. OPPS rates are revised each year via
    notice-and-comment rulemaking and are published before they
    4
    go into effect. See Amgen, Inc. v. Smith, 
    357 F.3d 103
    , 106
    (D.C. Cir. 2004).
    HHS generally sets the rates using a complex statutory
    formula. First, each covered outpatient service (or group of
    related services) is assigned an Ambulatory Payment
    Classification (APC). 42 U.S.C. § 1395l(t)(2)(B). HHS then
    establishes “relative payment weights” for each APC based on
    the median cost of providing the relevant services.
    Id. § 1395l(t)(2)(C).
    In that relative weighting process, HHS may
    decide, for instance, that given the cost to the hospital, a certain
    service should be reimbursed at twice the rate of a different
    service. Next, each APC’s relative weight is multiplied by a
    number known as the “conversion factor.”
    Id. § 1395l(t)(3)(D).
    The same conversion factor applies to all APCs.
    Id. Multiplying an
    APC’s relative payment weight by the
    conversion factor produces a dollar amount, which is the base
    “fee schedule amount” for that APC.
    Id. § 1395l(t)(4)(A).
    That
    amount is subject to a variety of possible further adjustments,
    such as adjustments reflecting regional wage differences,
    id. § 1395l(t)(4)(A),
    or “outlier adjustments” for hospitals facing
    unusually high operating costs,
    id. § 1395l(t)(5).
    When setting rates each year, HHS is required to reassess
    its choices: what services or groups of services should make
    up each APC, what an APC’s relative payment weight should
    be, and what statutory adjustments (such as for labor cost
    differences) should be applied.
    Id. § 1395l(t)(9)(A).
    Changes
    to any of those inputs will alter the payment rate for a particular
    service. Any change HHS makes in those respects, however,
    must not cause overall projected expenditures for the next year
    to increase or decrease.
    Id. § 1395l(t)(9)(B).
    Under this
    “budget-neutrality” requirement, an increase or decrease in
    projected spending must be offset by other changes.
    5
    HHS must also update the conversion factor each year in
    order to keep up with inflation in general health care costs.
    Id. § 1395l(t)(3)(C)(ii),
    (t)(3)(C)(iv). Increases to the conversion
    factor, of course, proportionately increase overall OPPS
    outlays. But adjustments to the conversion factor need not be
    implemented in a budget-neutral manner—indeed, it would
    make little sense to do so in light of the objective of keeping
    pace with inflation.
    The OPPS is designed to advance Congress’s goal of
    controlling Medicare Part B costs in two ways. First, the OPPS
    encourages hospital efficiency by setting payment rates
    prospectively and basing the amount on median cost. Second,
    because of the budget-neutrality requirement, overall OPPS
    expenditure growth should closely track annual increases to the
    conversion factor. Those increases are modest and their
    amount is prescribed by statute.
    Although HHS has significant control over the rate it will
    pay hospitals for a specific service under the OPPS system, the
    agency has little control over how frequently hospitals will
    provide that service. Consequently, even if payment rates
    remain constant, an increase in the amount of services provided
    will cause an increase in overall Medicare expenditures.
    Congress addressed that possibility in subparagraph (2)(F)
    of the OPPS statute, the provision centrally in issue in this case.
    Subparagraph (2)(F) directs HHS to “develop a method for
    controlling unnecessary increases in the volume of covered
    [outpatient] services.”
    Id. § 1395l(t)(2)(F).
    Relatedly,
    Congress also authorized HHS to reduce the conversion factor,
    thereby shrinking projected overall expenditures, if it
    “determines under methodologies described in [sub]paragraph
    (2)(F) that the volume of services paid for . . . increased beyond
    6
    amounts established through those methodologies.”
    Id. § 1395l(t)(9)(C).
    B.
    Some hospitals provide outpatient care at facilities known
    as off-campus provider-based departments (PBDs), which are
    located away from the physical site of the hospital. Off-
    campus PBDs are considered part of the hospital for regulatory
    purposes. See 42 C.F.R. § 413.65. For that reason, services
    provided at off-campus PBDs are reimbursed through the
    OPPS system. HHS thus has generally paid hospitals the same
    amount for outpatient care provided at an off-campus PBD as
    for outpatient care provided in the main hospital.
    At least some services provided at off-campus PBDs can
    also be provided by freestanding physician offices, i.e., medical
    practices unaffiliated with a hospital. Physician offices are
    generally reimbursed at a lower rate for a given service than
    hospitals, because hospitals receive a separate “facility” rate
    inapplicable to freestanding physician practices. See Medicare
    Program: Proposed Changes to Hospital Outpatient
    Prospective Payment and Ambulatory Surgical Center
    Payment Systems and Quality Reporting Programs, 83 Fed.
    Reg. 37,046, 37,142 (July 31, 2018).
    Consider the amounts Medicare paid for a service
    commonly provided by off-campus PBDs: “evaluation and
    management of a patient,” or E&M. In 2017, the E&M
    reimbursement rate for off-campus PBDs under the OPPS was
    $184.44 for new patients and $158.24 for established patients.
    By contrast, the 2017 E&M rate for freestanding physician
    offices—paid under a separate system known as the Physician
    Fee Schedule—was $109.46 for new patients and $73.93 for
    established patients. See
    id. Hospital-affiliated outpatient
                                  7
    departments thus received between 68% and 114% more in
    reimbursements per patient for the same service.
    According to the Medicare Payment Advisory
    Commission (MedPAC), which was established by Congress
    to advise HHS, see Pub. L. No. 105-33 § 4022, 111 Stat. 251,
    350, hospitals reacted to the incentive created by the payment
    differential between off-campus PBDs and independent
    physician practices. Almost a decade ago, hospitals began
    buying freestanding physician practices and converting them
    into off-campus PBDs, without much change in the facility or
    the patients served. MedPAC, Report to the Congress:
    Medicare Payment Policy 53, 59–61, 75–76 (Mar. 2014),
    https://go.usa.gov/xdCzV. MedPAC documented substantial
    increases in the provision of E&M services at hospital
    outpatient departments and little to no growth in the provision
    of the same services at physician offices. See
    id. at 42.
    From
    2011 to 2016, the provision of E&M services at off-campus
    PBDs grew by 43.8%. MedPAC, Report to the Congress:
    Medicare Payment Policy 73 (2018), https://go.usa.gov/xdCzu.
    By comparison, the provision of E&M services at freestanding
    physician practices grew by only 0.4%.
    Id. In 2015,
    Congress attempted to address the substantial
    growth in services provided at off-campus PBDs by enacting
    section 603 of the Bipartisan Budget Act of 2015, Pub. L. No.
    114-74, 129 Stat. 584, 597–98 (codified at 42 U.S.C.
    § 1395l(t)(21)).     Section 603 adopted something of a
    compromise approach. On one hand, it did not touch the
    reimbursement rates for existing off-campus PBDs. On the
    other hand, it established that off-campus PBDs coming into
    existence after the statute’s enactment would no longer be paid
    under the OPPS, but instead would be paid under the
    “applicable payment system under this part,” which HHS
    interpreted to be a rate equivalent to the Physician Fee
    8
    Schedule. 42 U.S.C. § 1395l(t)(21)(C). That change applied
    to every service—not just E&M services—provided at new off-
    campus PBDs.
    After section 603’s enactment, though, HHS still
    continued to observe steady growth in the volume of hospital
    outpatient services. 83 Fed. Reg. at 37,139. For the years 2016
    through 2018, the volume and intensity of services grew
    annually by 6.5%, 5.8%, and 5.4%, respectively.
    Id. And in
    its proposed OPPS rule setting rates for 2019, the agency
    projected that, without changes, volume would again increase
    by 5.3% in that year, leading to $75.3 billion in overall OPPS
    expenditures.
    Id. Outlays had
    been nearly $20 billion less only
    a few years earlier.
    Id. HHS determined
    that, despite the 2015 enactment of
    section 603, “the differences in payment for . . . services”
    continued to be “a significant factor in the shift in services from
    the physician’s office to the hospital outpatient department, . . .
    unnecessarily increasing hospital outpatient department
    volume.”
    Id. at 37,142.
    HHS believed that the “higher
    payment that is made under the OPPS, as compared to payment
    under the [Physician Fee Schedule], [was] likely to be
    incentivizing providers to furnish care in the hospital outpatient
    setting.”
    Id. at 37,141.
    Thus, although section 603 had
    removed the incentive for hospitals to purchase physician
    practices and convert them into off-campus PBDs on a going-
    forward basis, the statute did not remove the incentive to
    provide care in off-campus PBDs already in existence.
    In its rule proposing 2019 OPPS rates, HHS announced
    that it “consider[ed] the shift of services” it had observed to be
    “unnecessary if the beneficiary can safely receive the same
    services in a lower cost setting but is instead receiving services
    in the higher paid setting due to payment incentives.”
    Id. at 9
    37,142. The agency concluded that E&M services, which are
    routine clinic visits, fit the bill, and thus that “the growth in
    clinic visits paid under the OPPS is unnecessary.”
    Id. Having found
    an “unnecessary increase[] in the volume of
    covered [outpatient] services,” HHS proposed to exercise its
    subparagraph (2)(F) authority to “develop a method for
    controlling” the increase. 42 U.S.C. § 1395l(t)(2)(F); 83 Fed.
    Reg. at 37,142. Specifically, the agency proposed to cut E&M
    reimbursement rates to off-campus PBDs to the amount HHS
    pays to freestanding physician offices for providing the same
    service. “[C]apping the OPPS payment at the [Physician Fee
    Schedule]-equivalent rate,” the agency explained, “would be
    an effective method to control the volume of these unnecessary
    services because the payment differential that is driving the
    site-of-service decision [would] be removed.” 83 Fed. Reg. at
    37,142.
    Notably, HHS proposed to implement the E&M
    reimbursement cut in a non-budget-neutral manner. In other
    words, the agency would reduce payments without offsetting
    increases in reimbursements for other covered outpatient
    services.
    Id. at 37,142–43.
    Although the OPPS statute
    generally requires annual rate adjustments to be budget-neutral,
    see 42 U.S.C. § 1395l(t)(9)(B), the agency did not believe that
    requirement applied to methods for controlling volume under
    subparagraph (2)(F). 83 Fed. Reg. at 37,142–43. HHS chose
    not to apply the reimbursement cut in a budget-neutral manner
    because doing so “would not appropriately reduce the overall
    unnecessary volume of covered [outpatient] services, and
    instead would simply shift the movement of the volume within
    the OPPS system in the aggregate.”
    Id. at 37,143.
    HHS
    estimated that the proposed rule would reduce Medicare’s
    expenditures by approximately $610 million in 2019 alone,
    10
    with an additional $150 million saved by Medicare
    beneficiaries in the form of reduced coinsurance payments.
    Id. After receiving
    comments, the agency adopted its proposal
    as a final rule, with the only change that the E&M
    reimbursement cut would be phased in over two years. See
    Medicare Program: Changes to Hospital Outpatient
    Prospective Payment and Ambulatory Surgical Center
    Payment Systems and Quality Reporting Programs, 83 Fed.
    Reg. 58,818, 59,004–15 (Nov. 21, 2018).
    C.
    The American Hospital Association and various hospitals
    (whom we will refer to collectively as the Hospitals)
    challenged the 2019 rule in these actions, which were
    consolidated in the district court for purposes of addressing the
    parties’ cross-motions for summary judgment. See Am. Hosp.
    Ass’n v. Azar, 
    410 F. Supp. 3d 142
    , 146 (D.D.C. 2019). The
    Hospitals first argued that HHS’s reduction in reimbursement
    for E&M services exceeded the agency’s statutory authority
    because the reduction does not qualify as a “method for
    controlling unnecessary increases in . . . volume” under
    subparagraph (2)(F) of the OPPS statute. See
    id. at 150–51.
    The Hospitals also argued that HHS’s decision to cut
    reimbursement to preexisting off-campus PBDs contravened
    Congress’s decision to leave preexisting facilities unaddressed
    in section 603 of the Bipartisan Budget Act of 2015. See
    id. The district
    court agreed with the Hospitals’ first
    argument.
    Id. at 161.
    The court accordingly vacated as ultra
    vires the part of the challenged rule that reduced E&M
    reimbursement rates.
    Id. This appeal
    followed.
    11
    II.
    We must first consider whether we have jurisdiction to
    review the Hospitals’ claim. Subparagraph (12)(A) of the
    OPPS statute provides that “[t]here shall be no administrative
    or judicial review of” certain specified actions HHS takes in
    implementing the OPPS, including “the establishment of . . .
    methods described in paragraph (2)(F).”           42 U.S.C.
    § 1395l(t)(12)(A). The government contends that HHS’s cut
    to E&M reimbursement qualifies as such a “method.” Thus,
    the government argues, judicial review of that reimbursement
    cut is precluded by statute, and we should dispose of the case
    on that basis at the threshold without examining HHS’s
    authority to implement the rate reduction.
    We are unpersuaded. Although subparagraph (12)(A)
    forecloses judicial review of the agency’s “establishment of
    methods described in paragraph (2)(F),” the Hospitals’ claim is
    that the payment reduction at issue is not a “method[] described
    in paragraph (2)(F)” within the meaning of the statute. As a
    result, to determine whether the judicial-review bar applies in
    this case, we must decide whether the challenged agency action
    counts as a “method for controlling unnecessary increases in
    the volume of covered [outpatient] services.”
    Id. § 1395l(t)(2)(F).
    And that latter question is the merits issue
    presented here.
    Subparagraph (12)(A) therefore is a preclusion-of-review
    provision that “merges consideration of the legality of [agency]
    action with consideration of the court’s jurisdiction in cases in
    which the challenge to the [agency’s] action raises the question
    of the [agency’s statutory] authority.” 
    Amgen, 357 F.3d at 113
    –14 (quoting COMSAT Corp. v. FCC, 
    114 F.3d 223
    , 226–
    27 (D.C. Cir. 1997)). In such cases, if the court “find[s] that
    [the agency] has acted outside the scope of its statutory
    12
    mandate, we also find that we have jurisdiction.” 
    COMSAT, 114 F.3d at 227
    . Put differently, “the jurisdiction-stripping
    provision does not apply” if the agency’s action fails to qualify
    as the kind of action for which review is barred. Southwest
    Airlines Co. v. TSA, 
    554 F.3d 1065
    , 1071 (D.C. Cir. 2009). As
    a practical matter, then, the court can simply skip to the merits
    question in its analysis. See, e.g., id.; 
    Amgen, 357 F.3d at 114
    ;
    
    COMSAT, 114 F.3d at 227
    .
    This court has already construed the provision at issue here
    as “merging” the preclusion and merits analysis in that way. In
    Amgen, we stated that subparagraph (12)(A)’s preclusion on
    review of “other adjustments” to rates by HHS “extends no
    further than the Secretary’s statutory authority to make” such
    
    adjustments. 357 F.3d at 112
    . Accordingly, we concluded that
    subparagraph (12)(A) “precludes judicial review of any
    adjustment made by the Secretary pursuant to [his statutory]
    authority . . . but not of those for which such authority is
    lacking.”
    Id. at 113.
    We then proceeded to the merits question,
    ultimately holding that the challenged adjustment was within
    the agency’s statutory authority and that we thus lacked
    jurisdiction.
    Id. at 114,
    118. The government contends that
    Amgen’s treatment of subparagraph (12)(A) was dicta, but
    regardless, we fully agree with Amgen’s approach, under which
    we analyze the merits to decide whether we have jurisdiction.
    The government attempts to sidestep that result by
    pressing us to analyze the Hospitals’ claim under the ‘ultra
    vires review’ doctrine often attributed to Leedom v. Kyne, 
    358 U.S. 184
    (1958). That doctrine, which we have likened to a
    “Hail Mary pass,” “permits, in certain limited circumstances,
    judicial review of agency action for alleged statutory violations
    even when a statute precludes review.” Nyunt v. Chairman,
    Broad. Bd. of Governors, 
    589 F.3d 445
    , 449 (D.C. Cir. 2009).
    The government submits that the Hospitals’ challenge presents
    13
    such a circumstance and thus must satisfy the stringent
    requirements set out in DCH Regional Medical Center v. Azar,
    
    925 F.3d 503
    , 509 (D.C. Cir. 2019)—among them, that the
    agency plainly acted in excess of its delegated powers and
    contrary to a specific, clear, and mandatory prohibition in the
    statute.
    Id. The Hospitals’
    challenge does not implicate the Kyne
    framework. We are not asked to remedy a “statutory
    violation[] even when a statute precludes review.” 
    Nyunt, 589 F.3d at 449
    . Instead, the Hospitals argue that the “same agency
    error . . . simultaneously ma[kes] the jurisdictional bar
    inapplicable and compel[s] setting aside the challenged agency
    action.” DCH 
    Regional, 925 F.3d at 510
    (quotation marks
    omitted). Put differently, the Hospitals’ claim is that
    subparagraph (12)(A)’s bar on judicial review does not apply
    if their merits argument is correct, not that their merits
    argument is so obviously correct that we should consider it
    despite an applicable bar on our review. DCH Regional itself
    recognized the distinction between cases involving a “Kyne
    exception” and cases such as this one in which “the relevant
    statutory bar . . . [is] effectively coextensive with the merits.”
    Id. at 509–10.
    In sum, subparagraph (12)(A)’s bar on judicial review is
    inapplicable unless HHS’s challenged action qualifies as a
    “method for controlling unnecessary increases in . . . volume”
    under subparagraph (2)(F). Subparagraph (12)(A) then
    ultimately does not preclude judicial scrutiny of HHS’s action
    for consistency with subparagraph (2)(F). To be sure,
    subparagraph (12)(A) still forecloses inquiry into “whether
    [the] challenged agency decision is arbitrary, capricious, or
    procedurally defective.” 
    Amgen, 357 F.3d at 113
    . But such
    claims are not before us here. As to the claim the Hospitals do
    raise, the question whether the Hospitals are correct and the
    14
    question whether the preclusion provision bars review of their
    claim are one and the same. We thus turn to assessing whether
    HHS had statutory authority to implement the challenged E&M
    reimbursement reduction.
    III.
    A.
    We examine that question under the traditional Chevron
    framework, under which we defer to the agency’s reasonable
    interpretation of an ambiguous statute. See Chevron, U.S.A.,
    Inc. v. Nat. Res. Def. Council, Inc., 
    467 U.S. 837
    (1984). HHS
    is generally entitled to Chevron deference on judicial review of
    its interpretations of the Medicare statute. See Good Samaritan
    Hosp. v. Shalala, 
    508 U.S. 402
    , 414 (1993); Baystate Franklin
    Med. Ctr. v. Azar, 
    950 F.3d 84
    , 92 (D.C. Cir. 2020). The
    Hospitals urge us not to apply Chevron in this case for several
    reasons, none of which is persuasive.
    First, we disagree that HHS forfeited any right to Chevron
    deference. To the contrary, HHS explained in the district court
    why its interpretation was entitled to Chevron treatment,
    invoked the doctrine twice in its opening brief in our court, and
    argued for it again in its reply brief. And in any event, our
    decisions hold that Chevron deference is not subject to
    forfeiture based on an agency’s litigation conduct if the
    agency’s challenged action “interpret[ed] a statute it is charged
    with administering in a manner (and through a process)
    evincing an exercise of its lawmaking authority.”
    SoundExchange, Inc. v. Copyright Royalty Bd., 
    904 F.3d 41
    , 54
    (D.C. Cir. 2018). That is the case here. See 83 Fed. Reg. at
    59,009, 59,011.
    15
    Second, the Hospitals contend that HHS’s interpretation of
    subparagraph (2)(F) in the challenged rule is inconsistent with
    earlier agency pronouncements, such that the rule is arbitrary
    and unworthy of Chevron deference. See Encino Motorcars,
    LLC v. Navarro, 
    136 S. Ct. 2117
    , 2126 (2016). But HHS has
    never taken a definitive position on the scope of subparagraph
    (2)(F). The Hospitals point to one sentence in the agency’s first
    OPPS rulemaking cautioning that “[a]dditional study, analysis,
    and possible legislative modification would be necessary
    before [the agency] could consider implementing” a volume-
    control method involving direct changes to reimbursement.
    Medicare Program; Prospective Payment System for Hospital
    Outpatient Services, 63 Fed. Reg. 47,552, 47,586 (Sept. 8,
    1998). Even assuming that statement amounted to an
    announcement of agency policy, which is far from clear, its
    meaning is ambiguous. As the district court concluded in its
    decision, the agency might well have thought that a “possible
    legislative modification would be necessary” because its
    proposed volume-control method would have required
    amending a separate statutory formula pertaining to its
    proposal, not because it believed that direct rate changes could
    never qualify as a “method for controlling” volume under
    (2)(F). See Am. Hosp. 
    Ass’n, 410 F. Supp. 3d at 157
    n.8.
    Nor, contrary to the Hospitals’ contention, has HHS long
    viewed subparagraph (2)(F) to require volume-control methods
    to be budget-neutral. It is true that the agency previously
    implemented a volume-control method called “packaging,”
    which bundles related services together into a single payment
    group, in a budget-neutral manner. See Medicare Program:
    Changes to the Hospital Outpatient Prospective Payment
    System and CY 2008 Payment Rates, 72 Fed. Reg. 66,580,
    66,615 (Nov. 27, 2007). That example, though, does not
    establish that HHS viewed (2)(F) as requiring budget-
    neutrality. The agency implemented “packaging” via other
    16
    statutory authorities, including its power to alter the
    composition of APC groups and their scaled
    weights. See id.at 66,611, 66,615; 42 U.S.C. § 1395l(t)(2)(B)–
    (C), (t)(9)(A). Those adjustment authorities require budget-
    neutrality. See 42 U.S.C. § 1395l(t)(9)(B). HHS implemented
    packaging in a budget-neutral way not because it was a (2)(F)
    method, but because it involved other statutory adjustments
    that call for budget-neutrality. See 72 Fed. Reg. at 66,615
    (budget-neutrality implicated because of “changes in APC
    weights and codes” and resulting “shifts in median costs” of
    those APCs).
    Finally, we reject the Hospitals’ argument that Chevron
    does not apply when, as here, our consideration of the agency’s
    statutory authority merges with our consideration of the
    applicability of a preclusion provision. See Part 
    II, supra
    . That
    result would mean that Congress’s decision to enact a
    preclusion provision operated to enhance judicial scrutiny and
    restrict the agency’s leeway. In precluding judicial review of
    certain HHS actions, though, Congress necessarily intended the
    opposite outcome. See 
    Amgen, 357 F.3d at 112
    (noting “havoc
    that piecemeal [judicial] review of OPPS payments could bring
    about”).
    B.
    Having rejected the Hospitals’ arguments against applying
    Chevron, we proceed to review HHS’s interpretation of
    subparagraph 1395l(t)(2)(F) under Chevron’s two-step
    framework. We first ask whether “Congress has directly
    spoken to the precise question at issue.” 
    Chevron, 467 U.S. at 842
    . If so, our work is done, for we “must give effect to the
    unambiguously expressed intent of Congress.”
    Id. at 843.
    But
    if the statute is “silent or ambiguous with respect to th[at]
    specific issue,”
    id., we assume
    “Congress has empowered the
    17
    agency to resolve the ambiguity,” and we defer to the agency’s
    interpretation as long as it is reasonable. Util. Air Reg. Grp. v.
    EPA, 
    573 U.S. 302
    , 315 (2014).
    The question at issue is whether HHS may reduce the
    OPPS reimbursement for a specific service, and may
    implement that cut in a non-budget-neutral manner, as a
    “method for controlling unnecessary increases in the volume
    of” the service. 42 U.S.C. § 1395l(t)(2)(F). In our view,
    Congress did not “unambiguously forbid” the agency from
    doing so. Barnhart v. Walton, 
    535 U.S. 212
    , 218 (2002); Nat’l
    Ass’n of Clean Water Agencies v. EPA, 
    734 F.3d 1115
    , 1125
    (D.C. Cir. 2013). We further conclude that the agency
    reasonably read subparagraph (2)(F) to allow a service-
    specific, non-budget-neutral reimbursement cut in the
    circumstances we consider here. We therefore hold that the
    agency acted within its statutory authority.
    1.
    At step one of Chevron, “the court begins with the text,
    and employs ‘traditional tools of statutory construction’ to
    determine whether Congress has spoken directly to the issue.”
    Prime Time Intern. Co v. Vilsack, 
    599 F.3d 678
    , 683 (D.C. Cir.
    2010) (quoting 
    Chevron, 467 U.S. at 842
    –43 & n.9). Applying
    those tools, we conclude that the OPPS statute does not directly
    foreclose HHS’s challenged rate reduction.
    To begin with, a service-specific, non-budget-neutral rate
    reduction falls comfortably within the plain text of
    subparagraph (2)(F). Reducing the payment rate for a
    particular OPPS service readily qualifies, in common parlance,
    as a “method for controlling unnecessary increases in the
    volume” of that service. The lower the reimbursement rate for
    a service, the less the incentive to provide it, all else being
    18
    equal. Reducing the reimbursement rate thus is naturally suited
    to addressing unnecessary increases in the overall volume of a
    service provided by hospitals. As for whether a rate reduction
    under subparagraph (2)(F) can be non-budget-neutral, the
    provision simply says nothing about budget-neutrality. The
    text Congress enacted thus lends considerable support to the
    agency’s reading of the statute at Chevron step one. See Air
    Transp. Ass’n of Am. v. FAA, 
    169 F.3d 1
    , 4 (D.C. Cir. 1999)
    (because operative “language d[id] not preclude the [agency’s]
    interpretation,” the contrary “inference petitioner would draw
    as to the statute’s meaning [was] not inevitable”).
    The broader statutory context bolsters the agency’s view
    that subparagraph (2)(F) authorizes service-specific rate cuts.
    Under our decision in Amgen, the agency can alter the
    reimbursement rate for a particular service under its
    subparagraph (2)(E) authority to make “adjustments [it]
    determine[s] to be necessary to ensure equitable payments,” 42
    U.S.C. § 1395l(t)(2)(E); 
    see 357 F.3d at 117
    (upholding use of
    equitable-adjustment authority to change “payment amount for
    a single drug”). If the agency can adjust payment rates in
    furtherance of the expansive purpose of achieving equitable
    payments, it stands to reason that the agency can also adjust
    rates to accomplish the more focused goal of controlling
    unnecessary volume growth. Indeed, as the Amgen court saw
    it, HHS’s robust “discretion” to adjust payment rates is a
    central feature of the statutory 
    scheme. 357 F.3d at 114
    (quoting H.R. Rep. No. 105-149, at 1323 (1997) and H.R.
    Conf. Rep. No. 105-217, at 785 (1997)).
    The statutory context also supports construing
    subparagraph (2)(F) to allow non-budget-neutral adjustments.
    If the statute otherwise permits the agency to make a
    discretionary rate reduction as a method of volume control, it
    would be anomalous for the law to require the rate cut to be
    19
    implemented budget-neutrally. That would require HHS to
    redistribute the costs traceable to the provision of unnecessary
    services throughout the OPPS, resulting in no net savings to
    Medicare and largely negating the point of reducing
    reimbursement in the first place. See 83 Fed. Reg. at 37,142–
    43.
    The Hospitals warn that, on that reading, nothing
    “prevents [HHS] from engaging in cost-control measures that
    will disproportionately affect only some service providers and
    beneficiaries.” Hospitals Br. 7. But budget-neutrality offers
    little protection against such outcomes. If HHS reduces
    reimbursements for cardiac catheterizations and then
    redistributes the savings across the OPPS, that still hurts
    cardiologists much more than orthopedists even if cardiologists
    would get some money back in the form of slightly elevated
    reimbursements for other services they provide. The agency’s
    ability to advance Congress’s apparent goals in both budget-
    neutrality and subparagraph (2)(F)—namely, keeping growth
    in overall OPPS expenditures modest and predictable year to
    year, see generally supra pp. 5–6—would be undermined, not
    advanced, by requiring the savings from (2)(F) volume-control
    methods to be redistributed across the OPPS.
    The Hospitals also contend that, budget-neutrality aside,
    subparagraph (2)(F) unambiguously does not encompass
    service-specific rate adjustments. The Hospitals argue in that
    regard that subparagraph (2)(F) does no more than enable the
    agency to develop an “analytical mechanism for determining
    whether there is an unnecessary increase in volume.” Hospitals
    Br. 31 (formatting modified). That argument rests on reading
    subparagraph (2)(F) in conjunction with subparagraph (9)(C),
    which provides that:
    20
    If    the    Secretary     determines     under
    methodologies described in paragraph (2)(F)
    that the volume of services paid for under this
    subsection     increased    beyond     amounts
    established through those methodologies, the
    Secretary may appropriately adjust the update
    to the conversion factor otherwise applicable in
    a subsequent year.
    42 U.S.C. § 1395l(t)(9)(C).
    According to the Hospitals, subparagraph (9)(C) is the
    exclusive way for HHS to implement subparagraph (2)(F). On
    that understanding, (2)(F) empowers the agency to “develop a
    method” for diagnosing whether there has been too much
    growth in outpatient service volume, and if the agency decides
    there has, then it can respond by—and only by—using its
    (9)(C) authority to reduce the across-the-board conversion
    factor. (Recall that the conversion factor is the number by
    which relative payment weights for services are translated into
    actual reimbursement amounts.           See supra pp. 4–5.)
    Subparagraph (2)(F), under the Hospitals’ argument, does not
    itself authorize the agency to act on an unnecessary increase in
    volume upon finding that one exists, much less to do so on a
    service-specific basis. Rather, the agency can act only by
    reducing the overall conversion factor under (9)(C).
    That interpretation of subparagraph (2)(F) is difficult to
    square with the provision’s language. Subparagraph (2)(F)
    directs the agency to develop “a method for controlling
    unnecessary increases” in volume, not just a method for
    assessing whether unnecessary increases exist. And we think
    it unlikely that Congress would have confined the agency’s
    volume-control arsenal to the very blunt instrument of reducing
    the across-the-board conversion factor. The Hospitals identify
    21
    no reason to suppose that Congress would have been concerned
    only about overall OPPS volume growth, which the conversion
    factor can suitably address, but not about unwarranted growth
    in the volume of a single service, which the conversion factor
    cannot.     Cutting the conversion factor would reduce
    reimbursement equally for every OPPS service, a poorly
    tailored, ineffectual “method” of controlling undesirable
    volume growth in a specific service.
    The Hospitals respond that HHS’s reading of (2)(F)
    renders subparagraph (9)(C) redundant, because cutting the
    conversion factor fits textually as a “method for controlling”
    unnecessary volume. We do not see the redundancy.
    Subparagraph (9)(C) appears to come into play only after the
    agency first attempts to address unnecessary volume increases
    through methodologies implemented under subparagraph
    (2)(F): “If the Secretary determines under methodologies
    described in paragraph (2)(F) that” volume has “increased
    beyond amounts established through those methodologies, the
    Secretary may appropriately adjust the update to the conversion
    factor applicable in a subsequent year.”             42 U.S.C.
    § 1395l(t)(9)(C) (emphases added). Because the (9)(C)
    authority thus kicks in only after the (2)(F) authority has been
    attempted and found inadequate, the former necessarily is not
    redundant of the latter.
    At any rate, even if subparagraph (9)(C) did amount to
    surplusage under HHS’s reading of (2)(F), that would not
    necessarily compel rejecting the agency’s interpretation of
    (2)(F) at Chevron step one. “[A]t times Congress drafts
    provisions that appear duplicative of others—simply, in
    Macbeth’s words, ‘to make assurance double sure.’” Fla.
    Health Scis. Ctr., Inc. v. Sec’y of Health & Human Servs., 
    830 F.3d 515
    , 520 (D.C. Cir. 2016) (citation omitted)). There may
    have been particular reason for Congress to do so here. In
    22
    specifying how HHS is to calculate the conversion factor, the
    statute envisions that the conversion factor will generally be
    “increased” each year, 42 U.S.C. § 1395l(t)(3)(C), (t)(3)(C)(ii).
    In that light, Congress could have thought it desirable to
    confirm the agency’s power to reduce the conversion factor in
    response to volume growth, as subparagraph (9)(C) does.
    Next, the Hospitals argue that subparagraph (2)(F)’s
    silence on budget-neutrality is itself evidence that Congress
    could not have intended the provision to allow direct rate
    adjustments. As noted, subparagraph (2)(F) does not address
    whether volume-control “method[s]” under that provision must
    be implemented in a budget-neutral fashion. Yet the OPPS
    statute nearly always specifies, one way or the other, whether
    a rate-adjustment authority must be exercised budget-neutrally.
    See Am. Hosp. 
    Ass’n, 410 F. Supp. 3d at 159
    (citing
    provisions).     To the Hospitals, subparagraph (2)(F)’s
    comparative silence indicates that Congress did not intend the
    provision to authorize changes to payment rates.
    But subparagraph (2)(F) undisputedly authorizes actions
    other than direct rate adjustments, and for at least some of those
    actions, a budget-neutrality requirement would make no sense.
    For example, the Hospitals do not dispute that subparagraph
    (2)(F) would allow HHS, as a volume-control method, to
    require additional paperwork from hospitals seeking
    reimbursement for certain outpatient procedures. That kind of
    volume-control method, of course, is insusceptible to a budget-
    neutrality mandate. Thus, (2)(F)’s silence on budget-neutrality
    tells us little about whether (2)(F) includes the authority to
    reduce a particular OPPS rate.
    Lastly, the Hospitals make a similar argument based on
    paragraph 1395l(t)(4), which sets out how “[t]he amount of
    payment made from the Trust Fund under this part for a
    23
    covered [outpatient] service . . . furnished in a year is
    determined.” 42 U.S.C. § 1395l(t)(4). Paragraph (4) makes no
    mention of subparagraph (2)(F). But it expressly allows
    payment amounts to be “adjusted” under other provisions, such
    as subparagraphs (2)(D) and (2)(E), which authorize various
    adjustments including labor-cost adjustments and equitable
    adjustments. That, the Hospitals contend, is strong evidence
    that Congress did not intend direct modification of OPPS
    payment rates via subparagraph (2)(F).
    Text and precedent, however, indicate that not all changes
    to OPPS rates must flow through paragraph (4). A number of
    provisions in the OPPS statute authorize HHS to set or adjust
    reimbursement rates for specific outpatient services but are
    unaddressed by paragraph (4). See 42 U.S.C. § 1395l(t)(14)
    (providing separate formula for calculating “amount of
    payment under this subsection for a specified covered
    outpatient drug”);
    id. § 1395l(t)(15)
    (prescribing “amount [to
    be] provided for payment for [an ungrouped] drug or biological
    under this part”);
    id. § 1395l(t)(16)(D)
    (requiring payment
    reduction for a certain surgical procedure performed by certain
    hospitals);
    id. § 1395l(t)(16)(F)(i)–(ii)
    (requiring payment
    reductions for various imaging services);
    id. § 1395l(t)(22)
    (authorizing Secretary to make “revisions to payments” “made
    under this subsection for covered [outpatient] services” in order
    to decrease opioid prescriptions). Consequently, paragraph (4)
    is best understood to set out only the general mechanism—not
    the exclusive mechanism—by which specific OPPS rates for
    covered services are “determined.”
    Our decision in Amgen supports that understanding of
    paragraph (4). In that case, HHS used its equitable-adjustment
    authority under subparagraph (2)(E) to reduce a “transitional
    pass-through” payment for a drug to zero 
    dollars. 357 F.3d at 107
    . The drug’s manufacturer complained that HHS could not
    24
    make that sort of equitable adjustment because paragraph (t)(6)
    lays out a specific formula for determining the “amount of the
    [transitional pass-through] payment.”         See 42 U.S.C.
    § 1395l(t)(6)(A), 1395l(t)(6)(D).       Amgen rejected that
    argument, holding that (t)(6)’s seemingly “mandatory”
    provisions establish only “default OPPS rate calculations
    subject to later 
    adjustment.” 357 F.3d at 115
    . Under Amgen,
    then, although (t)(6) specifies in detail how pass-through
    payments must be calculated without mentioning subparagraph
    (2)(E), the agency can nonetheless adjust the results of the
    (t)(6) formula using its (2)(E) authority. The same, we think,
    is true—or at least, not unambiguously untrue—of (t)(4) and
    (2)(F), respectively.
    We thus conclude that the OPPS statute does not
    unambiguously foreclose HHS’s adoption of a service-specific,
    non-budget-neutral rate cut as a “method for controlling
    unnecessary increases in” volume. 42 U.S.C. § 1395l(t)(2)(F).
    The statute is at least ambiguous as to whether that sort of rate
    adjustment lies within the agency’s (2)(F) authority.
    2.
    At Chevron step two, we ask whether the agency’s
    interpretation “is based on a permissible construction of the
    statute.” Nat’l Ass’n of Clean Water Agencies v. EPA, 
    734 F.3d 1115
    , 1128 (D.C. Cir. 2013) (quoting 
    Chevron, 467 U.S. at 843
    ). “A ‘reasonable’ explanation of how an agency’s
    interpretation serves the statute’s objectives is the stuff of
    which a ‘permissible’ construction is made.” Northpoint Tech.,
    Ltd. v. FCC, 
    412 F.3d 145
    , 151 (D.C. Cir. 2005) (citation
    omitted).
    The challenged rule meets that standard. The agency
    explained that recent growth in the volume of E&M services
    25
    provided at off-campus PBDs was “unnecessary because it
    appears to have been incentivized by the difference in payment
    for each setting rather than patient acuity.” 83 Fed. Reg. at
    59,007. The agency further concluded that reducing payments
    in order to eliminate that incentive “would be an effective
    method to control the volume of these unnecessary services
    because the payment differential that is driving the site-of-
    service decision will be removed.”
    Id. at 59,009.
    That interpretation of subparagraph (2)(F) is both
    “textually defensible” and “fits ‘the design of the statute as a
    whole and . . . its object and policy.’” Good Samaritan 
    Hosp., 508 U.S. at 418
    , 419 (quoting Crandon v. United States, 
    494 U.S. 152
    , 158 (1990)). It is reasonable to think that Congress,
    which cared enough about unnecessary volume to instruct the
    agency to “develop a method for controlling” it, would have
    wanted the agency to avoid causing unnecessary volume
    growth with its own reimbursement practices. We thus defer
    to the agency’s conclusion that (2)(F) allowed it to address that
    problem by reducing a specific rate.
    Sustaining HHS’s challenged reduction in this case would
    not necessarily leave the agency free “to set any payment rate
    for any service, without regard to the fine-grained statutory
    scheme enacted by Congress.” Hospitals Br. 45. It is one thing
    for HHS to use its subparagraph (2)(F) authority to eliminate a
    volume-growth incentive created, in the agency’s view, by a
    differential in its own payment rates. It may be another thing
    for the agency to reduce payment for a service under (2)(F)
    merely because doing so would decrease volume that HHS
    decides is “unnecessary.” We have no occasion to decide
    whether an action of that kind would rest on a reasonable
    interpretation of the OPPS statute. Cf. Nat. Res. Def. Council
    v. EPA., 
    777 F.3d 456
    , 469 (D.C. Cir. 2014) (agency’s
    interpretation cannot be “untethered to Congress’s approach”
    26
    at Chevron step two); 
    Amgen, 357 F.3d at 117
    (equitable
    adjustments may not “work basic and fundamental changes in
    the scheme Congress created in the Medicare Act” (quotation
    omitted)).
    In short, we conclude under Chevron that HHS’s reduction
    in reimbursement for E&M services provided by off-campus
    PBDs qualifies as a “method for controlling unnecessary
    increases in the volume of covered [outpatient] services.” 42
    U.S.C. § 1395l(t)(2)(F). Because the challenged rate cut is thus
    a “method[] described in paragraph (2)(F),” judicial review
    of that action is precluded by the statute.            See
    id. § 1395l(t)(12)(A).
    Consequently, neither we nor the district
    court has jurisdiction over the Hospitals’ challenge.
    IV.
    The Hospitals argue in the alternative that HHS’s decision
    to reduce E&M reimbursement to off-campus PBDs
    contravenes section 603 of the Bipartisan Budget Act of 2015.
    As explained, Congress enacted that provision in response to
    reports that the payment differential between off-campus PBDs
    and freestanding physician practices had induced hospitals to
    purchase those practices. Section 603 established that services
    performed at off-campus PBDs would no longer be paid under
    the OPPS but instead would be paid under a scheme
    approximating the Physician Fee Schedule. See 42 U.S.C.
    § 1395l(t)(1)(B)(v), 1395l(t)(21)(C). But the law exempted
    “department[s] of a provider . . . that [furnished covered
    outpatient services] prior to November 2, 2015.”
    Id. § 1395l(t)(21)(B)(ii).
    In the Hospitals’ view, Congress’s
    decision to leave the rates paid to preexisting off-campus PBDs
    unaddressed in section 603 means that the statute should be
    read to bar HHS from cutting reimbursement rates for those
    facilities.
    27
    Because the Hospitals’ section 603 argument targets
    agency action we have already determined qualifies as a
    “method[] described in paragraph (2)(F),” we are doubtful we
    have jurisdiction to consider it. See
    id. § 1395l(t)(12)(A).
    In
    any event, we reject the argument on the merits. (The law of
    our circuit allows a court to assume hypothetical statutory
    jurisdiction even if we cannot assume Article III jurisdiction.
    See Kramer v. Gates, 
    481 F.3d 788
    , 791 (D.C. Cir. 2007).)
    Nothing in the text of section 603 indicates that preexisting off-
    campus PBDs are forever exempt from adjustments to their
    reimbursement. Rather, the text of the law exempts those
    providers from the change mandated by section 603 itself,
    leaving the exempted providers subject to all the provisions of
    the OPPS statute, including subparagraph (2)(F). It bears
    noting, moreover, that section 603’s exemption of preexisting
    off-campus PBDs from the reimbursement reductions effected
    by that statute retains practical effect for all OPPS services
    except the one type of service (E&M services) addressed by the
    challenged rule.
    Trying a different approach, the Hospitals contend that
    section 603 demonstrates Congress’s judgment that increases
    in volume at preexisting off-campus PBDs are not
    “unnecessary” in the sense contemplated by subparagraph
    (2)(F). But even assuming that were true for increases in
    volume occurring by 2015, when section 603 was enacted, it
    would not mean that Congress considered acceptable the
    continued volume increases later taking place in 2016, 2017, or
    2018, on which HHS relied in adopting the challenged rule.
    See 83 Fed. Reg. at 37,139; MedPAC, Report to the Congress:
    Medicare       Payment      Policy     73     (Mar.     2018),
    https://go.usa.gov/xdCzu. Section 603 thus does not stand in
    the way of the agency’s challenged rate reduction under (2)(F).

    For the foregoing reasons, we reverse the judgment of the
    district court.
    So ordered.
