    Seattle, Washington
    Before: Susan P. Graber and William A. Fletcher, Circuit Judges, and Leslie E.
    Kobayashi,* District Judge.
    Opinion by Judge Graber
    GRABER, Circuit Judge:
    Renal dialysis is a life-saving treatment for those with serious kidney
    afflictions, including acute kidney injury and end-stage renal disease ("ESRD").
    *
    The Honorable Leslie E. Kobayashi, United States District Judge for
    the District of Hawaii, sitting by designation.
    Plaintiffs DaVita, Inc., and Star Dialysis (collectively, "DaVita") provide dialysis
    treatment to many patients and seek payment from any applicable group health
    plan. One of DaVita’s patients is a beneficiary of Defendant Amy’s Kitchen’s
    Employee Benefit Health Plan ("Amy’s Plan" or "the Plan"), a health plan offered
    and administered by Defendant Amy’s Kitchen, Inc. ("Amy’s Kitchen"). The
    patient has ESRD and has received routine maintenance dialysis from DaVita.
    Amy’s Plan covers all types of dialysis, regardless of the underlying diagnosis, but
    the Plan’s reimbursement rate for dialysis differs from the rate it pays for many
    other services. The Plan paid DaVita according to the Plan’s terms.
    Dissatisfied with the payment amounts that it received from Amy’s Plan,
    DaVita brought this action, arguing that the Plan’s dialysis provisions violate (1)
    the Medicare as Secondary Payer provisions ("MSP") of the Social Security Act,
    (2) the Employee Retirement Income Security Act of 1974 ("ERISA"), and (3)
    state law. The district court dismissed the federal claims and declined to exercise
    supplemental jurisdiction over the state-law claims. With respect to the MSP
    claim, the court held that, because the Plan reimburses at the same rate for all
    dialysis services, regardless of underlying diagnosis and regardless of Medicare
    eligibility, the Plan does not violate the MSP. Reviewing de novo and taking the
    allegations in the complaint as true, Daewoo Elecs. Am., Inc. v. Opta Corp., 875
    
    2 F.3d 1241
    , 1246 (9th Cir. 2017), we agree with the district court’s conclusions and
    therefore affirm.
    FACTUAL AND PROCEDURAL HISTORY
    Doctors classify chronic kidney disease into five stages. The last stage,
    Stage 5, is known as kidney failure or ESRD. More than 700,000 people in the
    United States have ESRD. To survive, a person with ESRD requires either a
    kidney transplant or routine maintenance dialysis, a treatment that performs the
    functions of a kidney. 42 C.F.R. § 406.13(b); see also Kidney Disease Statistics
    for the United States, Nat’l Insts. of Health (December 2016),
    https://www.niddk.nih.gov/health-information/health-statistics/kidney-disease.
    Most persons with ESRD never receive a kidney transplant, so they receive regular
    maintenance dialysis for the remainder of their lives. According to DaVita, a
    person with ESRD typically receives dialysis three times a week. Persons with
    ESRD are eligible for Medicare pursuant to 42 U.S.C. § 426-1 after the first three
    months of regular dialysis treatment.
    People with ESRD are not the only recipients of dialysis. The other
    common recipients of dialysis are those with "acute kidney injury," described by
    the National Kidney Foundation as "a sudden episode of kidney failure or kidney
    damage that happens within a few hours or a few days." Acute Kidney Injury,
    Nat’l Kidney Found. (Oct. 30, 2020), https://www.kidney.org/atoz/content/
    3
    AcuteKidneyInjury. Acute kidney injury has many different causes and correlated
    diseases.
    Id. Recently, for example,
    a study cited by the National Kidney
    Foundation concluded that "people hospitalized with COVID-19 are at significant
    risk of [acute kidney injury]." Kidney Disease and COVID-19, Nat’l Kidney
    Found., https://www.kidney.org/coronavirus/kidney-disease-covid-19 (last visited
    Nov. 16, 2020). Treatment of acute kidney injury restores long-term kidney
    function. Accordingly, unlike persons with ESRD, persons with acute kidney
    injury generally recover enough kidney function so that they no longer need
    dialysis. Similarly, unlike persons with ESRD, persons with acute kidney injury
    are not eligible for Medicare pursuant to 42 U.S.C. § 426-1.
    When a patient with ESRD is enrolled in both Medicare and a group health
    plan, the MSP allocates primary-payer responsibility between Medicare and the
    plan. Once the individual becomes eligible for Medicare, which occurs after three
    months of dialysis treatment, the plan remains the primary payer and Medicare
    becomes the secondary payer during a 30-month coordination period. 42 U.S.C.
    § 1395y(b)(1)(C)(i). When the coordination period ends, the plan may be the
    secondary payer thereafter.
    Id. § 1395y(b)(1)(C). The
    MSP also imposes two substantive requirements on group health plans
    with respect to persons with ESRD. First, during the coordination period, a plan
    may not "take into account" a person’s eligibility for Medicare due to ESRD.
    Id. 4
    § 1395y(b)(1)(C)(i). Second, a plan may not "differentiate in the benefits it
    provides between individuals having [ESRD] and other individuals covered by
    [the] plan on the basis of the existence of [ESRD], the need for renal dialysis, or in
    any other manner."
    Id. § 1395y(b)(1)(C)(ii). Amy’s
    Kitchen sells organic foods throughout the United States and
    employs more than 2,400 people. Many employees are eligible to enroll in Amy’s
    Plan, which is an "employee benefit plan" pursuant to ERISA. Amy’s Plan is a
    preferred provider organization health plan. A beneficiary may visit any medical
    provider, some of which are "in-network" and some of which are "out-of-network."
    For many medical services, the Plan provides no coverage at all, whether that
    service is given by an in-network or an out-of-network provider. But for most
    services covered by the Plan, the processing of claims depends on whether the
    beneficiary visits an in-network provider or an out-of-network provider. Visiting
    an in-network provider generally results in lower copayments and other advantages
    for beneficiaries. The Plan typically pays in-network providers according to a rate
    determined by contract and pays out-of-network providers, in the words of the
    Plan, the "Customary, Usual, and Reasonable Charge" for the service.
    "Patient 1" is a beneficiary of Amy’s Plan who has ESRD. Patient 1 began
    receiving regular dialysis treatment in 2016 from DaVita. At the time, DaVita was
    5
    an in-network provider, and the Plan reimbursed DaVita at the appropriate
    contractual rate.
    In 2017, Amy’s Plan modified its terms of coverage by implementing a
    "Dialysis Benefit Preservation Program." The Plan explained that it had found
    evidence of "significant inflation" of prices charged by dialysis providers; the use
    of inflated revenues "to subsidize reduced prices to other types of payers as
    incentives"; and "the specific targeting of the Plan and other non-governmental and
    non-commercial plans by the dialysis providers as profit centers." The Plan
    implemented the program because of its
    fiduciary obligation to preserve Plan assets against charges which (i)
    exceed reasonable value due to factors not beneficial to covered persons
    . . . and (ii) are used by the dialysis providers for purposes contrary to
    the covered persons’ interests, such as subsidies for other plans and
    discriminatory profit-taking.
    The Program applies to all claims for "reimbursement of products and
    services provided for purposes of outpatient dialysis, regardless of the condition
    causing the need for dialysis." The Plan no longer uses the in-network/out-of-
    network distinction for dialysis-related reimbursements. Instead, "[a]ll dialysis-
    related claims will be subject to cost review by the plan administrator to determine
    whether the charges indicate the effects of market concentration or discrimination
    in charges."
    With respect to dialysis-related claims, the plan administrator shall
    determine the Usual and Reasonable Charge based upon the average
    6
    payment actually made for reasonably comparable services and/or
    supplies to all providers of the same services and/or supplies by all
    types of plans in the applicable market during the preceding calendar
    year, based upon reasonably available data, adjusted for the national
    Consumer Price Index medical care rate of inflation.
    The "Usual and Reasonable Charge" differs from the "Customary, Usual, and
    Reasonable Charge" that applies to reimbursements for some other types of
    medical treatment.
    DaVita alleges that the reimbursements that it received beginning in 2017
    were far less than the reimbursements that it received in 2016. DaVita brought this
    action, alleging claims on its own behalf and as an assignee of Patient 1’s claims.
    DaVita alleges that the Plan’s 2017 implementation of the dialysis-specific
    program violated the MSP, ERISA, and state law. The district court dismissed
    with prejudice all federal claims and declined to exercise supplemental jurisdiction
    over the state-law claims. DaVita timely appeals.
    DISCUSSION
    A.     MSP Claim
    The MSP imposes two substantive requirements on group health plans with
    respect to persons with ESRD. A group health plan:
    (i) may not take into account that an individual is entitled to or eligible
    for benefits under this subchapter under section 426-1 of this title
    [during the 30-month coordination period]; and
    (ii) may not differentiate in the benefits it provides between individuals
    having end stage renal disease and other individuals covered by such
    7
    plan on the basis of the existence of end stage renal disease, the need
    for renal dialysis, or in any other manner[.]
    42 U.S.C. § 1395y(b)(1)(C). Amy’s Plan uniformly reimburses all dialysis
    treatments whether or not the beneficiary is eligible for Medicare and whether or
    not the beneficiary has ESRD. And dialysis is a treatment received by many
    people: some are eligible for Medicare and some are ineligible; some have ESRD
    and some do not have ESRD. DaVita nevertheless argues that, because the Plan
    allegedly pays less for dialysis treatments than for other treatments, the Plan
    violates both of the MSP’s requirements. For the reasons that follow, we disagree.
    1.     "Take Into Account"
    The MSP prohibits a plan from taking into account whether the covered
    individual is eligible for or enrolled in Medicare during the coordination period,
    after which time the plan may be the secondary payer. See
    id. § 1395y(b)(1)(C)(i) (providing
    that a plan "may not take into account that an individual is entitled to or
    eligible for [Medicare] benefits" (emphasis added)). The Plan plainly did not take
    into account Patient 1’s eligibility for, or enrollment in, Medicare. The Plan
    uniformly reimburses all dialysis treatment, whether or not the beneficiary is
    eligible for Medicare or enrolled in Medicare.
    Notably, many persons who receive dialysis are ineligible for Medicare:
    those with acute kidney injury are not, by virtue of that injury, eligible for
    Medicare, and even those who have ESRD are eligible for Medicare only after the
    8
    first three months of dialysis treatment. Yet the Plan takes no notice whatsoever of
    whether the claimant is eligible for Medicare. Claims are paid at the same rate
    whether the claimant has acute kidney injury, is in the first months of ESRD
    treatment, or is eligible for Medicare.
    Nor does it matter, for purposes of the MSP, that the Plan calculates its
    reimbursement rate by taking into account, along with other factors, the amount
    that Medicare pays for dialysis treatment of other individuals. The MSP bars
    consideration of the individual claimant’s eligibility for Medicare, a factor that the
    Plan ignores.
    Finally, our reading of the "take into account" provision renders neither that
    provision nor the differentiation provision superfluous. Both provisions serve
    functions that the other does not. The "take into account" provision prohibits a
    plan from taking Medicare eligibility into account during the 30-month
    coordination period and permits a plan to become the secondary payer after the
    coordination period. Nothing in the differentiation provision concerns who pays
    first. Similarly, the differentiation provision prohibits a plan from differentiating
    against any person who has ESRD, including a person who is ineligible for
    Medicare.
    In sum, Amy’s Plan did not "take into account" Patient 1’s eligibility for
    Medicare and thus comported with the MSP’s first requirement.
    9
    2.     Differentiation
    The MSP provides that a plan "may not differentiate in the benefits it
    provides between individuals having end stage renal disease and other individuals
    covered by such plan on the basis of the existence of end stage renal disease, the
    need for renal dialysis, or in any other manner." 42 U.S.C. § 1395y(b)(1)(C)(ii).
    Under the Plan, individuals with ESRD receive identical benefits, including
    dialysis benefits, as those who do not have ESRD. Renal dialysis is a potential
    treatment for all persons, not just for those with ESRD, and the Plan uniformly
    reimburses a provider for renal dialysis whether or not the patient has ESRD.
    Accordingly, the Plan does not—in any way or for any reason—"differentiate in
    the benefits it provides between individuals having end stage renal disease and
    other individuals covered by such plan."
    Id. The second half
    of the statutory text does not change that conclusion. Plans
    may not provide differing benefits to persons with ESRD "on the basis of the
    existence of end stage renal disease, the need for renal dialysis, or in any other
    manner."
    Id. The clause is
    grammatically challenging to interpret, because "on the
    basis of" appears to apply to "the need for renal dialysis" but cannot meaningfully
    apply to "in any other manner." See DaVita, Inc. v. Marietta Mem’l Hosp. Empl.
    Health Benefit Plan, 
    978 F.3d 326
    , 361 (6th Cir. 2020) (Murphy, J., concurring in
    part and dissenting in part) ("This list likely contains a typo because it makes no
    10
    sense to say ‘on the basis of . . . in any other manner.’" (ellipsis in original)). The
    corresponding regulation slips in an "or" to address the grammatical issue,
    prohibiting differentiation "on the basis of the existence of ESRD, or the need for
    renal dialysis, or in any other manner." 42 C.F.R. § 411.161(b)(1) (emphasis
    added). But we need not dwell on the nuances. Even the broadest possible reading
    of the second half of the statutory text—prohibiting differentiation in the provision
    of benefits for any reason and in any manner—does not change our interpretation
    of the requirement as a whole.
    A plan may not provide differing benefits to persons with ESRD than to
    other insureds, no matter the reason and no matter the manner. For example, a
    plan may not provide differing benefits to persons with ESRD simply because an
    individual has ESRD, or because an individual with ESRD needs renal dialysis, or
    because an individual with ESRD has a greater statistical chance of needing other
    services. See 42 U.S.C. § 1395y(b)(1)(C)(ii) (prohibiting differentiation "on the
    basis of the existence of end stage renal disease, the need for renal dialysis, or in
    any other manner"). And a plan may not provide differing benefits to persons with
    ESRD by, for example, terminating their coverage, charging higher premiums,
    exacting higher co-payments, or requiring longer waiting times. 42 C.F.R.
    § 411.611(b)(2)(i)-(iii). But the pertinent question remains whether the plan
    provides differing benefits to persons with ESRD than to all other insureds.
    11
    Because Amy’s Plan provides identical benefits, including dialysis benefits, to all
    insured persons, the Plan does not run afoul of the MSP.
    We do not hold that all facially neutral plans comply with the MSP. A
    facially neutral provision that, in effect, operated to differentiate "between
    individuals having end stage renal disease and other individuals covered by such
    plan" would not comport with the MSP. 42 U.S.C. § 1395y(b)(1)(C)(ii). For
    example, a plan would violate the MSP if it provided different coverage for routine
    maintenance dialysis—that is, dialysis received only by persons with ESRD—than
    for all other dialysis. See 42 C.F.R. § 411.161(b)(2)(v) (listing, as an example of a
    prohibited differentiation, a plan’s "[f]ailure to cover routine maintenance dialysis
    . . . when a plan covers other dialysis services"). So, too, would a plan violate the
    MSP if it declined to cover an ESRD-specific medication even though it covered
    comparable non-ESRD-specific medications. That is, provisions that affect only
    those with ESRD necessarily provide differing benefits to those with ESRD as
    compared to other insureds.
    But Amy’s Plan has no such differentiating effect. The Plan treats all
    dialysis the same, and persons with ESRD are not the exclusive recipients of
    dialysis. Many persons who do not have ESRD receive dialysis as treatment for
    12
    acute kidney injury.1
    DaVita concedes that dialysis is not exclusively a treatment for ESRD. But
    DaVita emphasizes that most people who receive dialysis have ESRD, so that
    Amy’s Plan has a remarkably disproportionate effect on persons with ESRD.
    DaVita encourages us to hold that the MSP’s prohibition on differing treatment
    bars not only actual differentiation (whether by name or by exclusive effect) but
    also all provisions that have a disproportionate effect, or disparate impact, on
    persons with ESRD.
    In assessing whether the MSP encompasses a disparate-impact theory, we
    find helpful the Sixth Circuit’s recent decision in 
    Marietta, 978 F.3d at 347
    –52.
    Applying the Supreme Court’s guidance in Texas Department of Housing &
    Community Affairs v. Inclusive Communities Project, Inc., 
    576 U.S. 519
    (2015),
    the Sixth Circuit held that the MSP encompasses a disparate-impact theory.
    
    Marietta, 978 F.3d at 350
    –51. Judge Murphy disagreed with the majority’s
    conclusion, writing separately to state his view that "a plan that uniformly offers
    the same benefits to all groups does not violate [the MSP’s differentiation] clause."
    1
    In 2000, about 12,000 persons in the United States with acute kidney injury
    received dialysis. Pavkov ME, Harding JL, Burrows NR., Trends in
    Hospitalizations for Acute Kidney Injury — United States, 2000–2014, Morbidity
    & Mortality Wkly. Rep., March 16, 2018, 67:289–293, Table,
    https://www.cdc.gov/mmwr/volumes/67/wr/mm6710a2.htm. That number rose to
    18,000 by 2006.
    Id. And in 2014,
    the number climbed to more than 28,000.
    Id. 13
    Id. at 360 
    (Murphy, J., dissenting in part). We agree with the Sixth Circuit that the
    Supreme Court’s decision in Inclusive Communities provides the appropriate
    framework for considering whether a statute encompasses a disparate-impact
    theory, but we disagree with the Marietta majority’s conclusion.
    Inclusive Communities considered whether the Fair Housing Act ("FHA")
    encompassed a disparate-impact theory of 
    liability. 576 U.S. at 533
    –34. The
    Court began its analysis by discussing "two other antidiscrimination statutes that
    preceded it"—Title VII of the Civil Rights Act of 1964, and the Age
    Discrimination in Employment Act of 1967 ("ADEA")—that the Court previously
    had held encompassed disparate-impact liability.
    Id. at 530–33;
    see Griggs v.
    Duke Power Co., 
    401 U.S. 424
    (1971) (Title VII); Smith v. City of Jackson, 
    544 U.S. 228
    (2005) (ADEA). The Court discussed the obvious similarities in text and
    structure between the relevant provisions of Title VII and the ADEA, on the one
    hand, and the relevant provisions of the FHA, on the other. Inclusive
    
    Communities, 576 U.S. at 534
    –35. Title VII provides:
    It shall be an unlawful employment practice for an employer—
    (1) to fail or refuse to hire or to discharge any individual, or otherwise
    to discriminate against any individual with respect to his compensation,
    terms, conditions, or privileges of employment, because of such
    individual’s race, color, religion, sex, or national origin; or
    (2) to limit, segregate, or classify his employees or applicants for
    employment in any way which would deprive or tend to deprive any
    individual of employment opportunities or otherwise adversely affect
    14
    his status as an employee, because of such individual’s race, color,
    religion, sex, or national origin.
    42 U.S.C. § 2000e-2(a) (emphases added); see Inclusive 
    Communities, 576 U.S. at 530
    –31 (quoting this text). The ADEA provides:
    It shall be unlawful for an employer—
    (1) to fail or refuse to hire or to discharge any individual or otherwise
    discriminate against any individual with respect to his compensation,
    terms, conditions, or privileges of employment, because of such
    individual’s age;
    (2) to limit, segregate, or classify his employees in any way which
    would deprive or tend to deprive any individual of employment
    opportunities or otherwise adversely affect his status as an employee,
    because of such individual’s age; or
    (3) to reduce the wage rate of any employee in order to comply with
    this chapter.
    29 U.S.C. § 623(a) (emphases added); see Inclusive 
    Communities, 576 U.S. at 532
    (quoting this text). The first relevant FHA provision states:
    It shall be unlawful for any person or other entity whose business
    includes engaging in residential real estate-related transactions to
    discriminate against any person in making available such a transaction,
    or in the terms or conditions of such a transaction, because of race,
    color, religion, sex, handicap, familial status, or national origin.
    42 U.S.C. § 3605(a) (emphasis added); see Inclusive 
    Communities, 576 U.S. at 534
    (quoting this text). The second relevant FHA provision states that it is
    unlawful:
    To refuse to sell or rent after the making of a bona fide offer, or to refuse
    to negotiate for the sale or rental of, or otherwise make unavailable or
    15
    deny, a dwelling to any person because of race, color, religion, sex,
    familial status, or national origin.
    42 U.S.C. § 3604(a) (emphasis added); see Inclusive 
    Communities, 576 U.S. at 533
    (quoting this text).
    The Court noted that the only textual difference is that Title VII and the
    ADEA use the phrase "or otherwise adversely affect" while the FHA uses the
    phrase "or otherwise make unavailable or deny."2 Inclusive 
    Communities, 576 U.S. at 532
    –33. But the Court held that the different wording was irrelevant
    because both formulations, and the word "discriminate," are "results-oriented
    language," which "counsels in favor of recognizing disparate-impact liability."
    Id. at 534.
    The Court explained further:
    It is true that Congress did not reiterate Title VII’s exact language in
    the FHA, but that is because to do so would have made the relevant
    sentence awkward and unclear. A provision making it unlawful to
    "refuse to sell[,] ... or otherwise [adversely affect], a dwelling to any
    person" because of a protected trait would be grammatically obtuse,
    difficult to interpret, and far more expansive in scope than Congress
    likely intended.
    Id. at 535
    (alterations and ellipsis in original).
    2
    In its briefing to us, DaVita also cites the disparate-impact provision in the
    Americans with Disabilities Act of 1990 ("ADA"), 42 U.S.C. § 12112. But that
    statute’s text, which prohibits many forms of "discriminat[ion]," does not differ
    meaningfully from the relevant text of Title VII or the ADEA.
    Id. § 12112(a); see
    also
    id. § 12112(b)(3) (defining
    ways that an entity may impermissibly
    discriminate to include "utilizing standards, criteria, or methods of administration
    . . . that have the effect of discrimination on the basis of disability" (emphasis
    added)).
    16
    The Supreme Court next found later amendments to the FHA, enacted in
    light of intervening court decisions, to be of "crucial importance."
    Id. In particular, "all
    nine Courts of Appeals to have addressed the question had
    concluded that the Fair Housing Act encompassed disparate-impact claims."
    Id. When Congress amended
    the FHA, it chose to retain the relevant statutory text
    and, moreover, added three new clauses that made sense only if the FHA
    encompassed a disparate-impact theory of liability.
    Id. at 536–39.
    Finally, the Court held that "[r]ecognition of disparate-impact claims is
    consistent with the FHA’s central purpose."
    Id. at 539.
    "The FHA, like Title VII
    and the ADEA, was enacted to eradicate discriminatory practices within a sector of
    our Nation’s economy." Id.; see also
    id. at 528–30
    (recounting the long history of
    discriminatory housing).
    The Court made clear that its conclusion that the FHA encompassed a
    disparate-impact theory resulted from considering all of the factors just discussed:
    "The Court holds that disparate-impact claims are cognizable under the Fair
    Housing Act upon considering its results-oriented language, the Court’s
    interpretation of similar language in Title VII and the ADEA, Congress’
    ratification of disparate-impact claims in 1988 against the backdrop of the
    unanimous view of nine Courts of Appeals, and the statutory purpose."

    (noting the unanimous holdings of the courts of
    appeal that the ADEA's prohibition encompasses disparate impacts).
    Applying the teaching of Inclusive Communities, we begin, as did the Sixth
    Circuit, with the statutory text:
    [A group health plan] may not differentiate in the benefits it provides
    between individuals having end stage renal disease and other
    individuals covered by such plan on the basis of the existence of end
    stage renal disease, the need for renal dialysis, or in any other manner.
    42 U.S.C. § 1395y(b)(1)(C)(ii) (emphases added). The Sixth Circuit’s majority
    focused exclusively on the final five words of the provision: "or in any other
    manner." 
    Marietta, 978 F.3d at 348
    –51. The court noted that, like the important
    statutory passage in the FHA, that passage is "at the end of a series of prohibitions
    that deal with disparate treatment" and "is exceedingly broad."
    Id. at 350
    (emphasis omitted). From those observations, the Sixth Circuit concluded that the
    MSP’s "non-differentiation provision permits a disparate impact claim."
    Id. at 351.
    We respectfully suggest that the Marietta majority’s analysis of whether the
    statute gives rise to a disparate-impact claim was incomplete. Not every list of
    actions followed by a broad catch-all clause means that Congress intended to
    encompass a disparate-impact theory. Inclusive Communities requires both a more
    detailed study of the statutory text and a consideration of other relevant factors.
    First, continuing with the textual analysis, a different aspect of the provision
    strongly suggests that Congress did not intend to create a disparate-impact theory
    18
    of liability. In particular, Congress chose to prohibit actions that "differentiate"
    rather than "discriminate." Just as the FHA’s use of the word "discriminate"
    suggested disparate-impact liability to the Supreme Court in light of the identical
    wording of Title VII and the ADEA, Inclusive 
    Communities, 576 U.S. at 534
    ,
    Congress’ decision not to use the word "discriminate" in the MSP strongly
    suggests that it did not intend to encompass disparate-impact liability. The
    presumption that different words carry different meanings is ordinarily weak when
    applied, as here, to different Acts, because "[w]e do not presume that when
    Congress legislates it has firmly in mind every term of every pre-existing statute."
    Agredano v. Mutual of Omaha Cos., 
    75 F.3d 541
    , 544 (9th Cir. 1996). But
    Congress certainly was aware of the important term "discriminate," which long has
    carried a particular meaning. We find it significant that Congress chose to avoid
    that common term in favor of a different verb, "differentiate." See Hall v. United
    States, 
    566 U.S. 506
    , 516 (2012) ("We assume that Congress is aware of existing
    law when it passes legislation." (internal quotation marks omitted)); see also Bare
    v. Barr, 
    975 F.3d 952
    , 968 (9th Cir. 2020) ("We must presume that Congress
    intended a different meaning when it uses different words in connection with the
    same subject." (internal quotation marks omitted)).
    Read as a whole, then, the statutory text does not suggest that Congress
    intended to sweep in actions that disproportionately affect persons with ESRD
    19
    under a disparate-impact theory. We may agree with the Sixth Circuit that the
    phrase "or in any other manner" is "results-oriented" in a sense. 
    Marietta, 978 F.3d at 350
    & n.15. But the statutory text makes clear that the pertinent inquiry remains
    whether the plan's provisions "result" in different benefits for persons with ESRD,
    not whether the plan's provisions disproportionately affect persons with ESRD or
    otherwise "discriminate" against persons with ESRD.
    Nor is there any indication that Congress acquiesced in a disparate-impact
    theory that has been widely adopted by the federal courts. If anything, the MSP’s
    statutory history and additional provisions suggest the opposite conclusion. For
    example, until just a couple of months ago, no court had held that the MSP
    encompasses a disparate-impact theory of liability. See, e.g., Nat'l Renal All., LLC
    v. Blue Cross & Blue Shield of Ga., Inc., 
    598 F. Supp. 2d 1344
    , 1354–55 (N.D.
    Ga. 2009) (rejecting, as failing to state a claim, an assertion that a plan’s uniform
    reimbursement for all dialysis constituted differentiation under the MSP).
    Additionally, and unlike the FHA, no other provision in the MSP assumes that the
    differentiation provision encompasses disparate-impact liability. Indeed, nearly
    every provision in the MSP concerns topics other than ESRD. In sum, one factor
    that was "of crucial importance," Inclusive 
    Communities, 576 U.S. at 535
    , in
    concluding that the FHA encompasses disparate impacts is, at best, completely
    absent with respect to the MSP.
    20
    Finally, we consider the statute’s "central purpose."
    Id. at 539.
    This factor,
    too, strongly suggests that Congress did not intend a disparate-impact theory of
    liability in the MSP. All of the anti-discrimination statutes cited by DaVita and the
    Sixth Circuit sought to address, as their sole or central purpose, a history of
    discrimination against a minority class of persons. As their titles suggest, the Fair
    Housing Act, Title VII of the Civil Rights Act, the Age Discrimination in
    Employment Act, and the Americans with Disabilities Act all aimed, as their
    central purpose, to address longstanding and entrenched discriminatory practices.
    By sharp contrast, there is little evidence, either in the legislative history of
    the MSP or in other sources, that persons with ESRD have been subjected to
    historical or entrenched societal discrimination akin to the discrimination faced by
    the classes of persons protected by the FHA, Title VII, the ADEA, and the
    ADA.3 As we hold in DaVita v. Virginia Mason Memorial Hospital, No. 19-
    35692, - F.3d – (9th Cir. 2020), ensuring equal health-care benefits for insureds
    who have ESRD, in limited circumstances, is one of the purposes of the Medicare
    3
    DaVita directs us primarily to a Senate Report in 1981—eight years before
    Congress added the differentiation provision—that expressed "concern[]" that
    employers might engage in "job discrimination" against persons entitled to
    Medicare. S. Rep. No. 97-139, at 736 (1981). Congress directed the relevant
    Secretary to "investigate promptly complaints of this nature[] and report his
    findings to the Congress."
    Id. That level of
    concern pales in comparison to, for
    example, Congress’ deep concern with the entrenched historical discrimination in
    housing on the basis of race. Inclusive 
    Communities, 576 U.S. at 528
    –30.
    21
    as Secondary Payer provisions. But the tightly cabined nature of the anti-
    differentiation provision of the MSP suggests a carefully circumscribed concern,
    not a remedy for widespread injustice. Moreover, the "central purpose," Inclusive
    
    Communities, 576 U.S. at 539
    , of the MSP provisions remains a congressional aim
    to save Medicare money. See Zinman v. Shalala, 
    67 F.3d 841
    , 845 (9th Cir. 1995)
    (noting that "the overarching statutory purpose" of the Medicare as Secondary
    Payer provisions is to "reduc[e] Medicare costs").
    Although this case concerns a plan’s reimbursement rates for dialysis, a
    disparate-impact theory presumably could give rise to a broad array of challenges.
    Notably, approximately half of persons with ESRD have diabetes or cardiovascular
    disease, and cardiovascular disease "contributes to more than half of all deaths
    among patients with ESRD." Kidney Disease Statistics for the United States, Nat’l
    Insts. of Health (December 2016), https://www.niddk.nih.gov/health-
    information/health-statistics/kidney-disease. Accordingly, a plan that provided less
    preferential coverage for those ailments might disproportionately affect persons
    with ESRD. Embracing a disparate-impact theory of liability would create
    uncertainty for insurers as to permissible provisions related to those illnesses. We
    doubt that Congress intended, in a statute aimed almost entirely at saving Medicare
    money, to require group health plans to ensure that its plans have no
    disproportionate effects on persons with ESRD. Rather, we conclude that
    22
    Congress meant what it said: a plan may not "differentiate in the benefits it
    provides between individuals having [ESRD] and other individuals covered by
    such plan." 42 U.S.C. § 1395y(b)(1)(C)(ii).
    In sum, consideration of the relevant factors described in Inclusive
    Communities confirms our reading of the statutory text. Congress prohibited
    group health plans from offering different benefits to persons with ESRD than to
    others, but it did not bar other differences that merely have a disproportionate
    effect on persons with ESRD.
    Although congressional intent is clear, we also note that the MSP’s
    implementing regulations provide no support for a disparate-impact claim. In both
    
    Smith, 544 U.S. at 239
    , and 
    Griggs, 401 U.S. at 433
    –34, the Supreme Court
    interpreted the pertinent statutory provision as encompassing a disparate-impact
    theory partly because the relevant agency had interpreted the statute in that
    manner. Similarly, although the Court in Inclusive Communities did not discuss
    the agency’s interpretation in its analysis, the Court noted at the outset that "the
    Secretary of Housing and Urban Development issued a regulation interpreting the
    FHA to encompass disparate-impact liability," including by establishing a multi-
    step "burden-shifting 
    framework." 576 U.S. at 527
    (abbreviation omitted).
    23
    The relevant regulations here tell a different story. Perhaps most
    convincingly, the agency expressly approved a plan provision that would have a
    clearly disproportionate effect on those with ESRD:
    (c) Uniform Limitations on particular services permissible. A plan is
    not prohibited from limiting covered utilization of a particular service
    as long as the limitation applies uniformly to all plan enrollees. For
    instance, if a plan limits its coverage of renal dialysis sessions to 30 per
    year for all plan enrollees, the plan would not be differentiating in the
    benefits it provides between plan enrollees who have ESRD and those
    who do not.
    42 C.F.R. § 411.161(c). Persons with ESRD typically require three dialysis
    sessions a week, so the hypothetical limitation would apply to all persons with
    ESRD. Persons with acute kidney injury, by contrast, rarely require 30 sessions of
    dialysis. In other words, even though the regulation’s hypothetical limitation
    would have an overwhelmingly disparate effect on persons with ESRD, the agency
    expressly approved the limitation as consistent with the MSP’s differentiation
    provision.
    Similarly, the agency’s illustrative examples in § 411.161(b)(2)4 all comport
    with our understanding of the statutory text. For example, a group health plan may
    4
    The regulation provides:
    (2) [Group health plan] actions that constitute differentiation in
    plan benefits (and that may also constitute "taking into account"
    Medicare eligibility or entitlement) include, but are not limited
    to the following:
    (continued)
    24
    not provide "less comprehensive health plan coverage" to "persons who have
    ESRD" and may not charge "individuals with ESRD higher premiums." 42 C.F.R.
    § 411.161(b)(2)(ii)-(iii). As is most relevant here, a plan may not decline to cover
    "routine maintenance dialysis" if it covers "other dialysis services," and a plan
    must pay identically for dialysis for persons with ESRD as for dialysis for persons
    who do not have ESRD.
    Id. § 411.161(b)(2)(iv)-(v). That
    is, a plan may not cover
    (i) Terminating coverage of individuals with ESRD, when there
    is no basis for such termination unrelated to ESRD (such as
    failure to pay plan premiums) that would result in termination for
    individuals who do not have ESRD.
    (ii) Imposing on persons who have ESRD, but not on others
    enrolled in the plan, benefit limitations such as less
    comprehensive health plan coverage, reductions in benefits,
    exclusions of benefits, a higher deductible or coinsurance, a
    longer waiting period, a lower annual or lifetime benefit limit, or
    more restrictive preexisting illness limitations.
    (iii) Charging individuals with ESRD higher premiums.
    (iv) Paying providers and suppliers less for services furnished to
    individuals who have ESRD than for the same services furnished
    to those who do not have ESRD, such as paying 80 percent of the
    Medicare rate for renal dialysis on behalf of a plan enrollee who
    has ESRD and the usual, reasonable and customary charge for
    renal dialysis on behalf of an enrollee who does not have ESRD.
    (v) Failure to cover routine maintenance dialysis or kidney
    transplants, when a plan covers other dialysis services or other
    organ transplants.
    42 C.F.R. § 411.161(b).
    25
    an exclusively-ESRD treatment differently than a comparable non-ESRD
    treatment; but nothing suggests that a plan must cover all dialysis treatments to the
    same extent as, say, chemotherapy or insulin treatments.
    We acknowledge one potential exception to the foregoing analysis. One of
    the regulation’s examples of impermissible differentiation is a plan’s failure to
    cover kidney transplants when the plan covers other organ transplants.
    Id. § 411.161(b)(2)(v). DaVita
    cites an article published in 2015 on the topic of
    kidney transplants, Educational Guidance on Patient Referral to Kidney
    Transplantation, U.S. Dept. of Health & Hum. Servs., (Sept. 2015),
    https://optn.transplant.hrsa.gov/resources/guidance/educational-guidance-on-
    patient-referral-to-kidney-transplantation. "With advances in surgical technique,
    immunosuppression, and post-transplant care, criteria for kidney transplantation
    have evolved dramatically."
    Id. Given the long
    waiting times for finding a
    suitable kidney donor, the article recommends that doctors consider referring some
    patients, especially those with rapidly progressive kidney disease, for evaluation
    for a kidney transplant even if the patient is in stage 4 of chronic kidney disease,
    one stage shy of ESRD (stage 5).
    Id. DaVita asserts that
    some patients receive a
    kidney transplant before their disease progresses to ESRD. The regulation
    therefore suggests, in DaVita’s view, that a disparate-impact theory is available.
    26
    The regulatory history does not reveal, when the agency promulgated the
    regulation in 1995, whether persons with stage 4 kidney disease received
    transplants; if so, whether the agency was aware of that fact; and if so, what the
    agency’s reason for including the example was. We need not investigate those
    questions, though, because even if we assume that the agency included one
    example that would support a disparate-impact claim, it suggests, at most, that the
    regulation is inconsistent with respect to the availability of a disparate-impact
    claim. See 
    Marietta, 978 F.3d at 351
    ("Put simply, the non-differentiation
    regulations do more to confuse than to clarify."). Whether we view the
    implementing regulations for the MSP as foreclosing entirely a disparate-impact
    theory or as inconsistent on the question, those regulations are wholly unlike the
    implementing regulations for Title VII, the ADEA, and the FHA, which clearly
    allowed disparate-impact claims. The regulations therefore provide no support for
    a disparate-impact claim.
    In conclusion, a plan that provides identical benefits to someone with ESRD
    as to someone without ESRD does not "differentiate" between those two classes.
    That simplistic approach must yield for treatments that apply exclusively to ESRD
    patients, because differential coverage of ESRD-specific treatments is no different
    than differential treatment of persons with ESRD. But for treatments that apply
    27
    both to those with ESRD and those without ESRD, a plan’s provision of identical
    benefits does not "differentiate" on any basis at all.
    Because Amy’s Plan provides identical benefits, including dialysis benefits,
    to persons with ESRD as to all other insureds and does not consider an individual’s
    eligibility for Medicare, Amy’s Plan comports with the MSP.5
    B.     ERISA Claims
    ERISA authorizes a beneficiary to bring claims seeking "to recover benefits
    due to him under the terms of his plan." 29 U.S.C. § 1132(a)(1)(B). Separate
    ERISA provisions authorize a beneficiary to bring equitable claims, seeking either
    injunctive or equitable relief.
    Id. § 1132(a)(1)(A) &
    (a)(3). DaVita asserts both
    types of claims.
    As DaVita acknowledges, it cannot bring ERISA claims on its own behalf.
    See
    id. § 1132(a)(1)(B) (allowing
    a claim for benefits "by a participant or
    beneficiary");
    id. § 1132(a)(3) (allowing
    equitable claims "by a participant,
    beneficiary, or fiduciary"); Spinedex Physical Therapy USA Inc. v. United
    Healthcare of Ariz., Inc., 
    770 F.3d 1282
    , 1289 (9th Cir. 2014) ("As a non-
    participant health care provider, Spinedex cannot bring claims for benefits on its

    Because both the 2016 version and the 2017 version of Amy’s Plan
    comported with the MSP, it is irrelevant that the 2017 amendment modified only
    the dialysis provisions of Amy’s Plan. See Curtiss-Wright Corp. v.
    Schoonejongen, 
    514 U.S. 73
    , 78 (1995) ("[P]lan sponsors are generally free under
    ERISA, for any reason at any time, to adopt, modify, or terminate welfare plans.").
    28
    own behalf."). DaVita seeks, instead, to bring claims on behalf of Patient 1, who
    signed a form assigning some causes of action to DaVita.
    The assignment form plainly encompasses a claim seeking to recover
    benefits, so DaVita may bring that claim. See 
    Spinedex, 770 F.3d at 1288
    –91
    (holding that a valid assignment of rights allows a third party to bring the
    beneficiary’s claim). But the complaint fails to state a claim. All of DaVita’s
    arguments stem from its argument, which we reject, that the Plan violates the MSP.
    Under the clear terms of the Plan, Patient 1 received all the "benefits due to him [or
    her] under the terms of [the] plan." 29 U.S.C. § 1132(a)(1)(B).
    We conclude that DaVita may not bring the equitable claims, however,
    because the assignment form did not encompass an assignment of equitable claims.
    "The question of what rights and remedies pass with a given assignment depends
    upon the intent of the parties." DB Healthcare, LLC v. Blue Cross Blue Shield of
    Ariz., Inc., 
    852 F.3d 868
    , 876 (9th Cir. 2017) (internal quotation marks omitted).
    To make that determination, "we look at the language and context of the
    authorization[]."
    Id. at 877.
    By signing the assignment form, Patient 1 agreed to thirteen numbered
    items. The fifth item included this sentence:
    I hereby assign to DaVita all of my right, title and interest in any cause
    of action and/or any payment due to me (or my estate) under any
    employee benefit plan, insurance plan, union trust fund, or similar plan
    ("Plan"), under which I am a participant or beneficiary, for services,
    29
    drugs or supplies provided by DaVita to me for purposes of creating an
    assignment of benefits under ERISA or any other applicable law.
    The Sixth Circuit recently held that a nearly identical assignment did not
    assign equitable claims, and we agree with its analysis on this point. 
    Marietta, 978 F.3d at 344
    –45. The wording of the assignment itself suggests only an assignment
    of a claim for benefits: Patient 1 assigned "all of [Patient 1’s] right, title and
    interest in any cause of action . . . under any employee benefit plan . . . for
    purposes of creating an assignment of benefits under ERISA or any other
    applicable law." (Emphasis added). The most natural reading of that sentence is
    that Patient 1 assigned all possible causes of action for the payment of benefits.
    The assignment of "any cause of action" is not superfluous because it refers to the
    causes of action available "under ERISA or any other applicable law," such as state
    contract law.
    The broader context of the sentence confirms that interpretation. The title of
    numbered item five is "Assignment of Benefits; Lien." And all of the remaining
    sentences of the same paragraph—such as how the patient should handle
    payments, the "automatic lien," and the pursuit of "collections"—pertain strictly to
    payments. Zooming out further still, the overall purpose of the document similarly
    focuses exclusively on responsibility for payments, affirming that the patient "is
    personally responsible for payments"; noting that the patient is "assigning rights to
    payments from my insurer"; and "authorizing DaVita to obtain the necessary
    30
    information to obtain such payments." (Emphases added.) As in 
    Spinedex, 770 F.3d at 1292
    , "the entirety of the Assignment indicates that [Patient 1] intended to
    assign to [DaVita] only [his or her] rights to bring suit for payment of benefits."
    See also DB 
    Healthcare, 852 F.3d at 876
    –77 (holding that an assignment implicit
    in "I Hereby Authorize My Insurance Benefits to Be Paid Directly to the
    Physician" encompassed only a claim for benefits and not equitable claims).
    AFFIRMED.
