HEALTH BENEFIT PLAN ET AL. v. DAVITA INC. ET AL.
CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR
THE SIXTH CIRCUIT
No. 20–1641. Argued March 1, 2022—Decided June 21, 2022
Petitioner Marietta Memorial Hospital Employee Health Benefit Plan is
an employer-sponsored group health plan that offers all of its partici-
pants the same limited coverage for outpatient dialysis. Respondent
DaVita—a major provider of dialysis services—sued the Marietta
Plan, arguing that the Plan’s limited coverage for outpatient dialysis
violated the Medicare Secondary Payer statute. The statute makes
Medicare a “secondary” payer to an individual’s existing insurance
plan for certain medical services, including dialysis, when that plan
already covers the same services. 42 U. S. C. §§1395y(b)(1)(C), (2), (4).
To prevent plans from circumventing their primary-payer obligation
for end-stage renal disease treatment, the statute imposes two con-
straints relevant here. First, a plan “may not differentiate in the ben-
efits 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.” §1395y(b)(1)(C)(ii). Second, a plan “may not take into ac-
count that an individual is entitled to or eligible for” Medicare due to
end-stage renal disease. §1395y(b)(1)(C)(i); see §426–1. The District
Court dismissed DaVita’s claims that the Marietta Plan violated both
statutory constraints. A divided panel of the U. S. Court of Appeals
for the Sixth Circuit reversed. Among other things, the Court of Ap-
peals ruled that the statute authorized disparate-impact liability and
that the limited payments for dialysis treatment had a disparate im-
pact on individuals with end-stage renal disease.
Held: Section 1395y(b)(1)(C) does not authorize disparate-impact liabil-
ity, and the Marietta Plan’s coverage terms for outpatient dialysis do
not violate §1395y(b)(1)(C) because those terms apply uniformly to all

covered individuals. Pp. 4–7.
(a) Section 1395y(b)(1)(C)(ii) prohibits a plan from differentiating in
benefits between individuals with and without end-stage renal dis-
ease. Because the Marietta Plan’s terms apply uniformly to individu-
als with and without end-stage renal disease, the Plan does not “dif-
ferentiate in the benefits it provides between individuals” with and
without end-stage renal disease. DaVita argues that the statute au-
thorizes liability even when a plan limits benefits in a uniform way if
the limitation on benefits has a disparate impact on individuals with
end-stage renal disease. But the text of the statute cannot be read to
encompass a disparate-impact theory. The statutory provision simply
coordinates payments between group health plans and Medicare; the
statute does not dictate any particular level of dialysis coverage.
Pp. 4–7.
(b) DaVita’s contention that a plan that provides limited coverage
for outpatient dialysis impermissibly “take[s] into account” the Medi-
care eligibility of plan participants with end-stage renal disease fails
for the same reason. Because the Marietta Plan provides the same
outpatient dialysis benefits to all Plan participants, whether or not a
participant is entitled to or eligible for Medicare, the Plan cannot be
said to “take into account” whether its participants are entitled to or
eligible for Medicare. Pp. 7.

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE SIXTH CIRCUIT
[June 21, 2022]
JUSTICE KAVANAUGH delivered the opinion of the Court.
The question in this case is whether a group health plan
that provides limited benefits for outpatient dialysis—but
does so uniformly for all plan participants—violates the
Medicare Secondary Payer statute. We agree with peti-
tioner Marietta and the United States as amicus curiae that
the answer is no. We therefore reverse the judgment of the
U. S. Court of Appeals for the Sixth Circuit and remand the
case for further proceedings consistent with this opinion.
I
A
Medicare provides health insurance coverage for those
who are 65 or over, or are disabled. In 1972, Congress ex-
tended Medicare coverage to individuals with end-stage re-
nal disease, regardless of age or disability. See Social Se-
curity Amendments of 1972, §299I, 86 Stat. 1463; 42
U. S. C. §426–1. That benefit now covers hundreds of thou-
sands of Americans with end-stage renal disease. In the
aggregate, the costs of healthcare for individuals with end-
stage renal disease are high, and Medicare spends about
2 MARIETTA MEMORIAL HOSPITAL EMPLOYEE HEALTH
BENEFIT PLAN v. DAVITA INC.
Opinion of the Court
$50 billion annually on treatments for those individuals.
During the initial years of the Medicare program after its
enactment in 1965, Medicare acted as the first payer for
many medical services, regardless of whether a Medicare
beneficiary was also covered under another insurance plan,
such as an employer-sponsored group health plan. In 1980
and 1981, in part due to rising Medicare costs, Congress en-
acted and amended the Medicare Secondary Payer statute.
That statute as amended makes Medicare a “secondary”
payer to an individual’s existing insurance plan for certain
medical services, including dialysis, when that plan already
covers the same services. See Medicare and Medicaid
Amendments of 1980, §953, 94 Stat. 2647; Medicare and
Medicaid Amendments of 1981, §2146, 95 Stat. 800; 42
U. S. C. §§1395y(b)(1)(C), (2), (4).
Given the significant costs of healthcare for those with
end-stage renal disease, Congress recognized that a plan
might try to circumvent the statute’s primary-payer obliga-
tion by denying or reducing coverage for an individual who
has end-stage renal disease, thereby forcing Medicare to in-
cur more of those costs. To prevent such circumvention, the
statute imposed two specific constraints on group health
plans. First, a plan “may not differentiate in the benefits it
provides between individuals having end stage renal dis-
ease and other individuals covered by such plan on the ba-
sis of the existence of end stage renal disease, the need for
renal dialysis, or in any other manner.” §1395y(b)(1)(C)(ii).
Second, as relevant here, a plan “may not take into account
that an individual is entitled to or eligible for” Medicare due
to end-stage renal disease. §1395y(b)(1)(C)(i); see §426−1.
B
DaVita is one of the two major dialysis providers in the
United States. DaVita provides dialysis to hundreds of
thousands of individuals each year, including individuals
insured by their employers’ group health plans.

Opinion of the Court
The Marietta Memorial Hospital Employee Health
Benefit Plan is an employer-sponsored group health plan.
The Plan offers the same terms of coverage for outpatient
dialysis to all of its participants. But under the Plan, out-
patient dialysis services are subject to relatively limited re-
imbursement rates.
In 2018, DaVita sued the Plan, arguing that the Plan’s
limited coverage for outpatient dialysis both (i) differenti-
ates between individuals with and without end-stage renal
disease and (ii) takes into account the Medicare eligibility
of individuals with end-stage renal disease in violation of
the Medicare Secondary Payer statute. §1395y(b)(1)(C).
The District Court dismissed DaVita’s claims, concluding
that the Plan does not violate the anti-differentiation or
take-into-account provisions of the Medicare Secondary
Payer statute because the Plan’s terms, including its terms
for outpatient dialysis treatments, apply uniformly to all
Plan participants.
A divided panel of the U. S. Court of Appeals for the Sixth
Circuit reversed. See 978 F. 3d 326 (2020). Among other
things, the Court of Appeals ruled that the statute author-
ized disparate-impact liability, and the Court concluded
that the limited payments for dialysis treatment had a dis-
parate impact on individuals with end-stage renal disease.
Judge Eric Murphy dissented in relevant part. He rea-
soned that the Plan’s terms do not violate the statute be-
cause the Plan “offers the same benefits to all participants.”
Id., at 358 (opinion concurring in judgment in part and dis-
senting in part).
The Sixth Circuit’s interpretation of the Medicare Sec-
ondary Payer statute departed from the holdings of district
courts that had considered the question. See DaVita, Inc.
v. Amy’s Kitchen, Inc., 379 F. Supp. 3d 960 (ND Cal. 2019);
Dialysis of Des Moines, LLC v. Smithfield Foods Healthcare
Plan, 2019 WL 8892581 (ED Va., Aug. 5, 2019); National

Inc., 598 F. Supp. 2d 1344 (ND Ga. 2009). Moreover, sev-

cuit agreed with Judge Murphy’s dissent and largely re-
jected the Sixth Circuit’s analysis. See DaVita Inc. v. Amy’s
Kitchen, Inc., 981 F. 3d 664 (2020).
This Court granted certiorari to resolve the disagreement
between the Courts of Appeals. 595 U. S. ___ (2021).

A
We first consider DaVita’s differentiation argument. To
reiterate, the relevant statutory provision states: A plan
“may not differentiate in the benefits it provides between
individuals having end stage renal disease and other indi-
viduals 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).
That statutory language prohibits a plan from differenti-
ating in benefits between individuals with and without end-
stage renal disease. For example, a group health plan may
not single out plan participants with end-stage renal dis-
ease by imposing higher deductibles on them, or by covering
fewer services for them. See 42 CFR §§411.161(b)(2)(i)–(iv).
If a plan does not differentiate in the benefits provided to
individuals with and without end-stage renal disease, then
a plan has not violated that statutory provision, and the dif-
ferentiation inquiry ends there.1
——————
1 If and only if a plan differentiates in benefits between those with and
those without end-stage renal disease, the next question would be
whether the plan differentiates “on the basis of ” (i) the existence of the
disease, (ii) the need for renal dialysis, or (iii) in any other manner. 42
U. S. C. §1395y(b)(1)(C)(ii). Those three circumstances, especially the
somewhat ungrammatically phrased catchall “in any other manner,” ap-
pear to cover the waterfront of possible bases on which a plan might dif-
ferentiate in the benefits provided to those with end-stage renal disease.
In other words, if there is differentiation, the differentiation is likely on
an impermissible basis. Therefore, the only meaningful question under
Cite as: 596 U. S. ____ (2022) 5
Opinion of the Court
The Marietta Plan provides the same benefits, including
the same outpatient dialysis benefits, to individuals with
and without end-stage renal disease. Indeed, DaVita does
not dispute that the Plan’s terms apply uniformly to all
Plan participants. Therefore, the Plan does not “differenti-
ate in the benefits it provides between individuals” with
and without end-stage renal disease. 42 U. S. C.
§1395y(b)(1)(C)(ii).
In response, DaVita primarily argues that the statute au-
thorizes liability even when a plan limits benefits in a uni-
form way if the limitation on benefits has a disparate im-
pact on individuals with end-stage renal disease.
To begin with, the text of the statute cannot be read to
encompass a disparate-impact theory. That text requires
inquiry into whether a plan provides different benefits to
(i) those with end-stage renal disease and (ii) those without
end-stage renal disease. The text does not ask about “the
effects of non-differentiating plan terms that treat all indi-
viduals equally.” 978 F. 3d, at 363 (opinion of Murphy, J.);
see also Amy’s Kitchen, 981 F. 3d, at 674−675. In light of
that plain text, it comes as no surprise that the Centers for
Medicare and Medicaid Services have never adopted a dis-
parate-impact theory in their longstanding regulations im-
plementing this statute.
The disparate-impact theory not only is atextual but also
would be all but impossible to fairly implement. The prem-
ise of the disparate-impact theory is that the plan’s benefits
for outpatient dialysis are inadequate. But what level of
benefits would be adequate, and how would courts deter-
mine the level of benefits that qualifies as adequate?
Neither the statute nor DaVita offers a basis for deter-
mining when coverage for outpatient dialysis could be con-
sidered inadequate. And neither the statute nor DaVita
——————
this statutory provision appears to be whether the plan differentiates in
benefits between those with and those without end-stage renal disease.
6 MARIETTA MEMORIAL HOSPITAL EMPLOYEE HEALTH
BENEFIT PLAN v. DAVITA INC.
Opinion of the Court
supplies an objective benchmark or comparator against
which to measure a plan’s coverage for outpatient dialysis.
Absent some benchmark or comparator, courts would
have great difficulty trying to make an apples-to-
apples comparison of a plan’s coverage for outpatient dialy-
sis against its coverage for other services. Group health
plans cover services for many different health issues at var-
ied rates. Those rates may reflect negotiations with third
parties, the needs of a particular plan’s beneficiaries, and
other factors such as geography. Courts would be entirely
at sea in trying to determine an appropriate benchmark or
comparator for outpatient dialysis. Put simply, DaVita’s
approach is a prescription for judicial and administrative
chaos, and further demonstrates that DaVita’s disparate-
impact theory is not a correct interpretation of the statute.2
DaVita’s position would ultimately require group health
plans to maintain some (undefined) minimum level of ben-
efits for outpatient dialysis. But this statutory provision
simply coordinates payments between group health plans
and Medicare. As the Government itself acknowledges, the
statute does not dictate any particular level of dialysis cov-
erage by a group health plan. See Brief for United States
as Amicus Curiae 13. If Congress wanted to mandate that
group health plans provide particular benefits, or to require
that group health plans ensure parity between different
kinds of benefits, Congress knew how to write such a law.
It did not do so in this statute. To the extent that Congress
——————
2 DaVita’s related proxy theory—that singling out outpatient dialysis
is simply a proxy for singling out individuals with end-stage renal dis-
ease because those individuals disproportionately receive outpatient di-
alysis—likewise finds no support in the statutory text. The statute re-
quires that a plan provide the same dialysis benefits regardless of
whether an individual has end-stage renal disease. If a plan provides
the same benefits to all individuals, the plan does not “differentiate in
the benefits it provides” to individuals with and without end-stage renal
disease. §1395y(b)(1)(C)(ii) (emphasis added). This statute is a coordi-
nation-of-benefits statute, not a traditional antidiscrimination statute.

Opinion of the Court
wants to create such a system going forward, Congress of
course may do so.
In sum, the Marietta Plan does not “differentiate in the
benefits it provides” to those with end-stage renal disease
and those without end-stage renal disease.
B
DaVita also contends that a plan that provides limited
coverage for outpatient dialysis impermissibly “take[s] into
account” the Medicare eligibility of plan participants with
end-stage renal disease in violation of the statute. To reit-
erate, that statutory provision states that a plan “may not
take into account that an individual is entitled to or eligible
for” Medicare. 42 U. S. C. §1395y(b)(1)(C)(i); see also §426–
1. For example, a plan may not terminate coverage, limit
coverage, or charge higher premiums for an individual who
has Medicare coverage due to end-stage renal disease. See
42 CFR §§411.108(a)(3), (5)−(6).
As already discussed, the Marietta Plan’s terms, includ-
ing its terms of coverage for outpatient dialysis, are uniform
for all individuals. Because the Plan provides the same out-
patient dialysis benefits to all Plan participants, whether or
not a participant is entitled to or eligible for Medicare, the
Plan cannot be said to “take into account” whether its par-
ticipants are entitled to or eligible for Medicare.
* * *
Because the Marietta Plan’s terms as relevant here apply
uniformly to all covered individuals, the Plan does not “dif-
ferentiate in the benefits it provides” to individuals with
end-stage renal disease or “take into account” whether an
individual is entitled to or eligible for Medicare. We there-
fore reverse the judgment of the U. S. Court of Appeals for
the Sixth Circuit and remand the case for further proceed-
ings consistent with this opinion.
It is so ordered.

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF
APPEALS FOR THE SIXTH CIRCUIT
[June 21, 2022]
JUSTICE KAGAN, with whom JUSTICE SOTOMAYOR joins,
dissenting in part.
Today the Court crafts for the Medicare Secondary Payer
Act (MSPA) a massive and inexplicable workaround. The
MSPA instructs that a group health plan “may not differ-
entiate in the benefits it provides between individuals hav-
ing 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 man-
ner.” 42 U. S. C. §1395y(b)(1)(C)(ii). The majority holds
that the plan here does not so “differentiate” because it
draws distinctions only between dialysis and other treat-
ments—not between individuals with end stage renal dis-
ease and individuals without it. See ante, at 6, n. 2. That
conclusion flies in the face of both common sense and the
statutory text.*
One fact is key to understanding this case: Outpatient di-
alysis is an almost perfect proxy for end stage renal disease.
Virtually everyone with end stage renal disease—and
——————
*Like the majority, I am unpersuaded by DaVita’s arguments concern-
ing disparate-impact liability and the MSPA’s separate take-into-ac-
count clause. See ante, at 5, 7. But I part ways with the majority as to
DaVita’s “proxy” theory (which the majority relegates to a footnote). See
ante, at 6, n. 2.
2 MARIETTA MEMORIAL HOSPITAL EMPLOYEE HEALTH
BENEFIT PLAN v. DAVITA INC.
KAGAN, J., dissenting in part
hardly anyone else—undergoes outpatient dialysis.
Ninety-seven percent of people diagnosed with end stage re-
nal disease—all those who do not obtain a preemptive kid-
ney transplant—undergo dialysis. See National Institutes
of Health, United States Renal Data System, 2021 Ann.
Data Rep.: End Stage Renal Disease, ch. 1, figure 1.2,
https://adr.usrds.org/2021/end-stage-renal-disease. And
99.5% of DaVita’s outpatient dialysis patients have or de-
velop end stage renal disease. See Brief for Respondents 6.
Because that is so, common sense suggests that we
should not care whether a health plan differentiates in ben-
efits by targeting people with end stage renal disease, or
instead by targeting the use of dialysis. When “status and
conduct” are proxies for each other, “[o]ur decisions have
declined to distinguish” between them. Christian Legal
Soc. Chapter of Univ. of Cal., Hastings College of Law v.
Martinez, 561 U. S. 661, 689 (2010). So, for example, we
have explained that a penalty for “homosexual conduct” is
a penalty for “homosexual persons.” Lawrence v. Texas, 539
U. S. 558, 575 (2003). And likewise, a “tax on wearing yar-
mulkes is a tax on Jews.” Bray v. Alexandria Women’s
Health Clinic, 506 U. S. 263, 270 (1993). The same goes
here: A reimbursement limit for outpatient dialysis is in re-
ality a reimbursement limit for people with end stage renal
disease. And so a plan singling out dialysis for disfavored
coverage “differentiate[s] in the benefits it provides be-
tween individuals having end stage renal disease and other
individuals.” §1395y(b)(1)(C)(ii). That is so even if, as pe-
titioner Marietta notes, dialysis is also a treatment for some
miniscule number of people with acute kidney injury. See
Reply Brief 13. That a proxy is only 99.5% (not 100%) ac-
curate should make no difference. A tax on yarmulkes re-
mains a tax on Jews, even if friends of other faiths might
occasionally don one at a Bar Mitzvah.
And if common sense were not enough, statutory text
would come to the rescue. Congress was well aware of the
Cite as: 596 U. S. ____ (2022) 3
KAGAN, J., dissenting in part
relationship between end stage renal disease and dialysis—
and the text it wrote reflects that knowledge. The statute
proscribes not just differentiation “on the basis of the exist-
ence of end stage renal disease,” but also “on the basis of . . .
the need for renal dialysis, or in any other manner.”
§1395y(b)(1)(C)(ii). The back half of that provision prevents
exactly the circumvention the majority today allows. It
bars plans from differentiating between people with and
without end stage renal disease even when that differenti-
ation is accomplished indirectly—by targeting their treat-
ment, or by relying on some other proxy for the condition.
So contra the majority, the statutory text does indeed pro-
hibit differentiation as to services—and not only as to indi-
viduals. See ante, at 6, n. 2.
That reading also fits with the statute’s purpose. As the
majority recognizes, the MSPA’s renal disease provisions
were designed to prevent plans from foisting the cost of di-
alysis onto Medicare. See ante, at 2. Yet the Court now
tells plans they can do just that, so long as they target dial-
ysis, rather than the patients who rely on it, for disfavored
coverage. Congress would not—and did not—craft a statute
permitting such a maneuver. Now Congress will have to fix
a statute this Court has broken. I respectfully dissent.
