not allowed to enroll in MA plans but could be enrolled in MA plans in limited circumstances.

For example, Medicare beneficiaries with ESRD could remain in MA plans if they were
diagnosed with ESRD while already enrolled in an MA plan. In 2019, there were 534,000

Medicare beneficiaries with ESRD, of whom approximately 25% (131,000) were in MA plans.
The CY2021 policy change, which Congress required in the 21st Century Cures Act (Cures Act; P.L. 114-255), is expected to
increase the number of MA enrollees with ESRD by 83,000 (more than 60%) over six years, with half the increase in
CY2021.
Congress enacted the Cures Act change for several reasons. Most ESRD patients undergo thrice-weekly dialysis treatments to
stay alive, and many have other chronic health conditions that require medical care, such as diabetes, heart disease, or
hypertension. Patient advocates and lawmakers have said that ESRD patients, because of their complex medical conditions,
could benefit from joining MA plans, which are required to ensure continuity of care and integration of services. In addition,
MA plans include a cap on annual enrollee out-of-pocket spending, which is not a feature of original, or fee-for-service
(FFS), Medicare. Because ESRD patients have high medical bills, they may realize savings by enrolling in an MA plan.
Private insurers that sponsor MA plans have expressed concern about expanded ESRD enrollment due, in part, to the higher
cost of covering such enrollees. Congress and the Centers for Medicare & Medicaid Services (CMS) attempted to address the
cost issue by requiring organ acquisition costs associated with kidney transplants for ESRD patients to be paid by FFS
Medicare rather than by MA plans. Still, MA plan sponsors told CMS the proposed changes in payment to comply with the
Cures Act would not adequately account for the increased costs.
On June 2, 2020, CMS issued a final rule to govern MA plan operations for CY2021 that implemented the Cures Act
provisions. One portion of the rule has drawn scrutiny and a lawsuit from ESRD patient advocates. As part of the regulation,
CMS codified existing, less-formal network guidance that limits the length of time and the geographic distance MA plans can
require enrollees to travel to obtain services from network providers and medical facilities. However, the rule waived the time
and distance limits for one set of providers, outpatient dialysis facilities (dialysis clinics), which had long been subject to
such limits. CMS justified the change on the grounds that relaxing the standards would help MA plans offer their enrollees a
broader array of dialysis services, including home-based dialysis. CMS also pointed to the statutory and regulatory
requirement that plans must provide access to Medicare required dialysis services with reasonable promptness and in a
manner that ensures continuity of benefits, consistent with “the prevailing community pattern of health care delivery in the
area.” Commercial insurers, which favor the rule, said it would encourage market competition. By contrast, dialysis providers
and patient groups said the rule could allow MA plans to drop outpatient dialysis facilities —which serve approximately 90%
of Medicare ESRD patients undergoing dialysis—from their plan networks in favor of home-based dialysis, which currently
is not widely used by ESRD beneficiaries. These opponents also argued that eliminating time and distance standards for
outpatient dialysis could put an excessive burden on ESRD enrollees, especially low-income and minority enrollees, if they
were required to either switch dialysis modalities (if that were an option) or travel longer distances for treatments. On June
24, 2020, a dialysis patient group filed suit in federal court to halt the rule on the grounds it discriminated against patie nts
who needed outpatient dialysis.

MA Coverage of ESRD and Network Requirement Changes

Introduction
Starting in calendar year (CY) 2021, al Medicare beneficiaries with end stage renal disease
(ESRD) are al owed to enroll in Medicare Advantage (MA) plans, which are an alternative way to
receive Medicare-covered benefits and, often, supplemental services. Prior to CY2021,
beneficiaries with ESRD, in general, were not al owed to enroll in MA plans but could be
enrolled in MA plans in limited circumstances. For example, Medicare beneficiaries with ESRD
were al owed to remain in MA plans if they were diagnosed with ESRD while enrolled in one. In
2019, there were 534,000 Medicare beneficiaries with ESRD, of whom approximately 25%
(131,000) were in MA plans. The CY2021 policy change, which Congress required in the 21st
Century Cures Act (Cures Act; P.L. 114-255),1 is expected to increase the number of MA
enrollees with ESRD by 83,000 (more than 60%) over six years, with half the increase in
CY2021.2
Congress enacted the Cures Act change for several reasons. Most ESRD patients undergo thrice-
weekly dialysis treatments to stay alive, and many have other chronic health conditions that
require medical care, such as diabetes, heart disease, or hypertension. Patient advocates and
lawmakers have said that ESRD patients, because of their complex medical conditions, could
benefit from joining MA plans, which are required to ensure continuity of care and integration of
services.3 In addition, MA plans include a cap on annual enrollee out-of-pocket spending, which
is not a feature of original, or fee-for-service (FFS), Medicare.4 Because ESRD beneficiaries have
high medical bil s, they may realize savings by enrolling in an MA plan.
Private insurers that sponsor MA plans have expressed concern about expanded ESRD enrollment
due, in part, to the high cost of covering such enrol ees.5 Congress and the Centers for Medicare

costs associated with kidney transplants for ESRD patients to be paid by FFS Medicare rather

than by MA plans. Stil , MA plan sponsors told CMS the proposed changes in payment to comply
with the Cures Act would not adequately account for the increased costs.6
In preparation for the Cures Act change, on June 2, 2020, CMS issued a final rule to govern MA
plan operations for CY2021.7 The rule implemented changes in MA enrollment, payment, and
other issues specifical y related to ESRD beneficiaries. In addition, the rule made more general
changes in MA program operations, including codifying network adequacy requirements.
MA plan networks consist of contracted providers and facilities that agree to provide care to MA
plan enrollees.8 In most cases, MA enrollees must use providers and facilities in their plan’s
network; in some cases, however, MA enrollees may use providers outside of their network,
possibly with higher cost sharing. Plans are al owed to limit the providers and facilities from
which enrollees can seek care (i.e., establish a network), as long as the plans make benefits
available and accessible to each enrollee with reasonable promptness and in a manner that assures
continuity in the provision of benefits,9 consistent with the prevailing community pattern of care
delivery in the area.10 As part of MA program changes, the rule codified existing CMS guidelines
that quantify measures of health care network adequacy, such as the minimum number of network
providers and medical facilities in an area, and limits on the length of time and the geographic
distance that MA plans may require their enrollees to travel to receive in-network services.11
However, the final rule waived these explicit time and distance limits for one type of provider—
outpatient dialysis facilities—that had been included in previous network adequacy guidance.
CMS justified the change on the grounds that it would al ow MA plans to offer enrollees a
broader array of dialysis services, including home-based dialysis.12

6 Starting in 2021, when organ acquisition costs for kidney transplant are paid by fee-for-service (FFS) Medicare,
historical FFS Medicare expenditures attributed to organ acquisition also are removed from the MA benchmarks. T he
president and CEO of America’s Health Plans wrote, “We remain concerned with the methodology CMS proposes to
exclude organ acquisition costs for kidney transplant from MA benchmarks. T he magnitude of the cost carve -out and
the resulting impacts on premiums and benefits could be very significant in many urban areas. Given the potential
impacts on all MA enrollees, we reiterate the request in our comments on the CY2021 Advance Notice that CMS
provide more transparency regarding the calculation of the carve-out factors.” Letter from Matthew Eyles, President

Commercial insurers that advocated for the rule said eliminating requirements regarding time and
distance limits for outpatient dialysis facilities would encourage greater competition among
dialysis providers seeking to join MA plan networks. They asserted that the change could
improve plans’ ability to negotiate reductions in reimbursement to dialysis providers.13 MA plans
already had an incentive to offer home dialysis as an alternative to outpatient dialysis, because the
U.S. market for outpatient dialysis is dominated by two national companies, which may make it
difficult for MA plans to negotiate favorable financial terms when developing their provider
networks. However, the existing for-profit chains also dominate the home dialysis market, which
means that, ultimately, new entrants to the market may be needed to increase competition. (See
“MA Plan Concerns About ESRD Payments and Dialysis Provider Competition,” below.)
Dialysis operators and provider groups opposed eliminating the quantified time and distance
requirements for outpatient dialysis providers. They posited that this change would al ow MA
plans to reduce the number of outpatient dialysis facilities in their networks—facilities that
currently serve approximately 90% of Medicare ESRD patients undergoing dialysis. Opponents
of the rule are concerned that MA plans instead would meet CMS network requirements by
offering home-based dialysis, which is not widely used (although CMS has mounted a series of
efforts to expand the treatment14) and is not feasible for some beneficiaries.15
CMS indicates that if network dialysis providers are incapable of meeting enrollees’ medical
needs because the burden of enrollees’ travel to in-network providers proves inconsistent with
prevailing community patterns of care, MA plans would have to arrange for out-of-network care
at in-network cost-sharing rates. Nonetheless, patient groups that oppose the rule argue that
eliminating the time and distance requirements for outpatient dialysis providers would discourage
some beneficiaries with ESRD from ever enrolling in MA plans. They also claim the change
would put an excessive burden on those who enrolled in MA plans prior to 2021, especial y low-
income and minority enrollees, who could be forced to travel long distances for thrice-weekly
treatments.16 On June 24, 2020, a dialysis patient group filed suit in federal court to halt the CMS
final rule on the grounds it was discriminatory.17

In addition to the new rule, the ongoing Coronavirus Disease 2019 (COVID-19) pandemic
heightens concerns about potential disruptions in dialysis care; for 2021, ESRD enrollees wil
choose whether to switch to MA plans or between plans in the midst of this increased uncertainty.
The pandemic has accelerated CMS efforts to expand home dialysis so patients do not have to
leave their homes three times a week for services. In addition, some patients hospitalized with
COVID-19 require dialysis, increasing hospitals’ dialysis use and further straining the system.
(See “Stakeholder and Support Agency Positions and Reactions to the Rule.”)
This report begins with an overview of Medicare coverage of ESRD services, including dialysis
treatment modalities and outpatient dialysis payment methodology. It also briefly discusses the
market for outpatient dialysis services. The report then describes the MA program (and how it
differs from original Medicare), including program payments to plans, enrollment of ESRD
beneficiaries, and historical network adequacy standards. It then describes provisions in the Cures
Act that eliminated the prohibition of enrollment by beneficiaries with ESRD into MA plans. In
addition, it describes selected provisions in CMS’s final rule related to implementing the Cures
Act provision, including changes to MA ESRD payments and MA network adequacy standards
for outpatient dialysis. The report summarizes the positions of different stakeholders and
concludes with issues to consider for plan year 2021 and beyond.
Coverage and Payment of ESRD Services Under
Original Medicare
ESRD is the final stage of chronic kidney disease (CKD), which is the gradual decrease of kidney
function over time. Individuals with ESRD have substantial and permanent loss of kidney
function and require either regular dialysis (a process that removes harmful waste products from
an individual’s bloodstream) or a kidney transplant to survive.18
Summary of Fee-for-Service ESRD Benefits
In 1972, Congress enacted legislation al owing qualified individuals with ESRD under the age of
65 to enrol in the federal Medicare health care program (Social Security Amendments of 1972;
P.L. 92-603). The legislation marked the first time individuals were al owed to enroll in Medicare
based on a specific medical condition rather than on age.19 Medicare now accounts for more than
three-fourths of al spending on U.S. patients with ESRD.20 Medicare ESRD benefits include
thrice-weekly dialysis treatments (at outpatient centers, at home, or, for hospitalized patients, at
inpatient medical facilities) and coverage for kidney transplants, including the costs of kidney
acquisition. ESRD enrollees under the age of 65 face an initial waiting period for coverage, and
coverage terminates 12 months after a patient ends dialysis or after 36 months of follow -up care
after a kidney transplant.21

18 CRS Report R45290, Medicare Coverage of End-Stage Renal Disease (ESRD).
19 An individual under the age of 65 who is medically determined to have ESRD and who is undergoing treatment is
eligible to enroll in Medicare if he or she has worked in Social Security -covered employment for a minimum number of
quarters or is entitled to an annuity under the Railroad Retirement Act. If an individual has an insufficient work history,
he or she may be able to qualify for Medicare based on the work history o f a spouse, parent, or guardian (SSA §226A).

Individuals who qualify for Medicare based on ESRD rather than age are eligible for al
Medicare-covered services, including Medicare Part A coverage of hospital care and Part B
coverage of physician and post-acute care services.22 Such beneficiaries also may enroll in the
voluntary Part D prescription drug program. Part A and Part B benefits are cal ed original, or fee-
for-service (FFS), Medicare, because Medicare pays providers and facilities for each item or
episode of service. Medicare Part C (MA) plans offer Part A and Part B benefits through private
insurers and, general y, as part of a managed care network of providers. Medicare beneficiaries
under the age of 65 who qualify for Medicare based on ESRD up until CY20201 were al owed to
enroll in MA plans only in limited circumstances. Once enrolled, MA enrollees are covered for
the same items and services provided under original Medicare (see “Medicare Advantage,”
below); however, unlike FFS Medicare, MA plans are paid a per-person monthly amount
regardless of the actual amount of health care a beneficiary used in the month.
Dialysis Treatment Modalities for ESRD Patients
There are two main forms of treatment for ESRD—kidney transplants and dialysis. A kidney
transplant is the preferred treatment for ESRD, but it is not the most common treatment due to a
shortage of donor kidneys. At present, the estimated waiting time for a kidney is nearly five years,
making it difficult to expand this treatment option. As of June 2020, 101,360 people were on the
waiting list for a kidney transplant. The waiting list is maintained by the United Network for
Organ Sharing.23 Overal , in 2017, about 30% of U.S. individuals with a diagnosis of ESRD had
been treated with a functioning kidney transplant. (See Table 1, below.)
The remaining 70% of individuals with ESRD in 2017 depended on dialysis, which is the process
of filtering an individual’s blood with a solution known as a dialysate to remove harmful wastes,
salt, and water—a process that otherwise would be performed by functioning kidneys. (See Table
1, below.) Dialysis also helps to control blood pressure and the levels of other chemicals in the
blood. Dialysis does not cure ESRD, and it carries other health risks. However, many people
undergoing dialysis are able to carry on a range of normal activities. Dialysis usual y is started
when an individual has lost 85%-90% of kidney function. Average life expectancy for an
individual on dialysis is 5-10 years, although people can live far longer.24

course of dialysis. If an individual ended a course of dialysis but later needs to resume treatment, entitlement to Part A
and eligibility to enroll in Part B begin in the month in which a regular course of renal dialysis is resumed. See SSA
§226A(c).

a. Hemodialysis and peritoneal dialysis are home dialysis methods.
There are two main types of dialysis, hemodialysis and peritoneal dialysis. The following sections
describe them in greater detail.
Hemodialysis
Hemodialysis is the most common form of dialysis. In hemodialysis, an external machine acts as
an artificial kidney (dialyzer). Blood is removed from the body through a system of tubes, with
access usual y through a vein in an arm, and is filtered and replaced. Hemodialysis typical y lasts
four hours at a time and is performed three times a week at a dialysis center. A form of
hemodialysis can be carried out by a patient in his or her home. Home hemodialysis may involve
more frequent and longer sessions and can include nocturnal treatments.25
Peritoneal Dialysis
In peritoneal dialysis, a patient’s blood is cleaned inside his or her body, using a catheter inserted
into the abdominal cavity.26 Dialysis solution flows through the catheter into a patient’s bel y to
absorb wastes and other fluids. After a few hours, the solution and wastes are drained. This type
of dialysis is often performed at home or other clean, private locations outside of a dialysis center,
such as an outpatient location. Peritoneal dialysis may work better for certain populations that
may not be able to tolerate hemodialysis, such as children or elderly patients with heart disease.27

Overview of Outpatient Facility and Home Dialysis Providers
CMS defines an ESRD facility as an entity that provides outpatient maintenance dialysis services,
home dialysis training and support services, or both. The regulations categorize ESRD facilities
as either hospital-based or independently operated.28 To receive Medicare reimbursement for
maintenance dialysis services, ESRD facilities must be certified by CMS as meeting safety and
quality standards.29
There were about 7,441 dialysis facilities in the United States in 2018. Of those, 95% were
freestanding dialysis facilities and 5% were hospital-based. Of the total number of dialysis
centers, 88% were for-profit and 12% were nonprofit. Most dialysis facilities (83%) are located in
urban areas.30
The U.S. dialysis industry is dominated national y by two for-profit companies: DaVita Inc. and
Fresenius Medical Group, which together accounted for 75% of Medicare FFS-reimbursed
dialysis treatments in 2018. Patients also may obtain outpatient dialysis at facilities owned by
hospitals and other nonprofit and for-profit providers, including physician groups. There are
limited data on dialysis provider concentration at the local level. A 2017 study that compared
dialysis providers in 2001 with dialysis providers in 2011 found that approximately half of the
local dialysis markets became more highly concentrated during the period. The consolidation did
not limit patient choice, on average.31
DaVita
DaVita, headquartered in Delaware, operated 2,753 outpatient dialysis centers in 46 states and the
District of Columbia in 2019, serving about 207,000 patients. DaVita also provided acute
inpatient dialysis services in about 900 U.S. hospitals.32 Outpatient dialysis made up 82% of
DaVita services and 78% of revenues, whereas home-based dialysis accounted for 13% of
services and 16% of revenues; hospital services and revenues made up the rest.
According to DaVita, approximately 90% of the dialysis patients it serves have health care
coverage through a government health care program, with 74% covered by original Medicare and
MA plans. Medicare payments accounted for 59% of DaVita’s U.S. dialysis revenues for 2019,
whereas private health insurance payers accounted for 31%, Medicaid and Managed Medicaid
plans for 6%, and other government programs for 4%.

Although Medicare accounts for the majority of DaVita’s dialysis revenue, private health
insurance payers, which pay significantly higher rates for dialysis services than Medicare,
generate nearly al of DaVita’s profits, according to the company.
Fresenius
Fresenius is headquartered in Germany, with a North American headquarters in Massachusetts.33
In 2019, North American sales accounted for 70% of the company’s revenues. Fresenius Kidney
Care operates more than 2,500 outpatient renal dialysis and home dialysis training facilities in the
United States, serving more than 206,000 people.34
Fresenius and DaVita together have a significant share of the home dialysis market, and both
companies have indicated they want to expand their home dialysis business.35 In addition, there
are nonprofit and smal er home dialysis providers,36 and some large companies are taking steps to
get into the market. For example, CVS Health has set up a subsidiary—CVS Kidney Care—but is
in the early stages of its efforts.37
Original Medicare Payment for Dialysis Services
When the ESRD benefit was first implemented, Medicare paid health care providers separate
amounts for tests, supplies, drugs, and covered services bil ed for ESRD patients. Over the years,
Congress made a number of changes to the payment system in an effort to control costs, including
paying dialysis providers a composite rate for many services. As part of the Medicare
Improvements for Patients and Providers Act of 2008 (P.L. 110-275), Congress required CMS to
implement a prospective payment system (PPS) for Medicare dialysis services. A PPS is a method
of payment in which amounts or rates of payment are established in advance for a defined period
and general y are based on an episode of care, regardless of the actual amount of care used.
The ESRD PPS, which was phased in over a four-year period starting in 2011, provides a single,
bundled payment to a certified ESRD facility for each dialysis treatment. Patients general y are
al owed up to three dialysis treatments per week, either in a dialysis center or at a patient’s home.
Additional treatments may be covered on the basis of medical necessity. The PPS bundled
payment covers dialysis and necessary support services, such as training, laboratory tests, drugs
related to ESRD treatment, and ESRD-related supplies.38 Physicians are paid separately for care
(see “Nephrologist Payments,” below).

MA Coverage of ESRD and Network Requirement Changes

A portion of Medicare reimbursement to dialysis providers is tied to a provider’s success in
meeting specific quality-of-care measures.39 Under the ESRD Quality Incentive Program (QIP),
CMS annual y evaluates whether outpatient dialysis facilities meet a detailed set of standards.
Facilities that fal short of the CMS requirements can have their Medicare reimbursement reduced
by up to 2%.40
CMS also is operating a series of pilot programs designed to test new approaches to paying for
ESRD care:
 CMS has been overseeing a five-year pilot program to evaluate coordinated care
models for serving ESRD beneficiaries. Under the CMS Comprehensive ESRD
Care (CEC) model, which runs from 2015 through 2020, physicians, dialysis
clinics, and other providers have formed ESRD Seamless Care Organizations
(ESCOs) to care for ESRD patients. ESCOs are reimbursed based on clinical and
financial outcomes, including spending on dialysis services, for the ESRD
beneficiaries they treat. According to CMS, the model aims to encourage dialysis
providers to broadly address beneficiaries’ health needs.41
 On September 18, 2020, CMS announced a final rule to institute a new pilot
program, beginning January 1, 2021, designed to increase home dialysis and
kidney transplantation by altering Medicare payment rates under the ESRD PPS
and the Medicare Physician Fee Schedule. The pilot program applies to FFS
Medicare and encompasses providers and facilities in 30% of U.S. hospital
referral regions, which CMS chose at random. Participation is mandatory for
providers and facilities chosen for the pilot, although ESRD beneficiaries retain
the right to choose their providers.42 The model is intended to test whether
adjusting FFS payment rates wil improve rates of home dialysis and kidney
transplants and whether doing so wil improve or maintain quality of care.

Improvements for Patients and Providers Act of 2008 ( P.L. 110-275).
40 Not all facilities are subject to the QIP standards. For example, a facility must treat a minimum number of cases to
fall under review. Any percentage reduction is applied to all Medicare payments for related services performed by the
facility receiving the reduction during the applicable payment year.

organizations. Large dialysis operators, defined as those with 200 or more dialysis facilities, will be eligible for shared
savings payments, will be liable for shared losses, and will have higher levels of risk compared with their smaller
counterparts. Non-large dialysis organizations, including chains with fewer than 200 dialysis facilities, independen t
dialysis facilities, and hospital-based dialysis facilities, will have the option of participating in a one-sided track where
they can receive shared savings payments but will not be liable for payment of shared losses or participating in a track

 On July 10, 2019, CMS announced the Kidney Care Choices (KCC) model
(formerly the Comprehensive Kidney Care [CKC] model). The KCC model
includes financial incentives for physicians, dialysis centers, and other providers
that coordinate care for participating beneficiaries with chronic kidney disease or
ESRD and for reducing the total cost of care for these beneficiaries. It also
provides financial incentives for successful transplants.43
Home Dialysis Payments
The Medicare benefit covers the training and equipment needed for beneficiaries to perform
dialysis in a home setting, including delivery, instal ation, monitoring, and maintenance of home
dialysis supplies and equipment.44 In recent years, Congress and CMS have modified the
Medicare ESRD benefit in an effort to expand use of home dialysis, based on data indicating
comparable outcomes and satisfaction with home-based care versus other types of dialysis.45
Since 2011, dialysis providers have been paid the same rate for offering home-based dialysis as
for providing outpatient dialysis at one of their facilities.46 Dialysis providers also may receive an
add-on to the PPS payment for having a nurse provide self-dialysis training for patients starting
home dialysis, including as many as 15 training sessions for peritoneal dialysis and 25 for home
hemodialysis.47
In the Bipartisan Budget Act of 2018 (P.L. 115-123) Congress al owed the use of telehealth for
ESRD patients undergoing home dialysis. (In addition, CMS has waived certain regulations
governing home dialysis, relaxed some standards for home dialysis, and increased the use of
telehealth during the COVID-19 pandemic.48)

MA Coverage of ESRD and Network Requirement Changes

The Trump Administration in 2019 set a goal of having 80% of new ESRD patients receiving
either home dialysis or a transplant by 2025, as part of a larger initiative on combatting kidney
disease.49 In July 2020, CMS proposed changes to Medicare payments for dialysis services that
would provide two-year add-on payments to the ESRD PPS bundle for adoption of advanced
equipment for home-based dialysis as an additional incentive for expanded home dialysis
services.50
The share of Medicare ESRD beneficiaries who are using home dialysis increased from 10% in
2013 to 12% in 2018.51 However, the increase in home dialysis growth slowed between 2014 and
2017, partly due to a shortage of the solutions needed for peritoneal dialysis. There are also
differences in utilization among different segments of the ESRD population. For example,
research has found that Whites and Asian Americans have been more likely to use home dialysis
than other racial or ethnic groups, although differences have been narrowing.52 Younger ESRD
patients are also more likely to use home dialysis.53
There are a number of reasons for low usage of home dialysis, including low patient awareness,
lack of education and training for enrollees and physicians, health and living conditions that make
it impossible for beneficiaries to perform home dialysis, and lack of support services needed to
assist those performing dialysis at home.54 Although some beneficiaries may switch between

Clinical, operational, policy, and societal barriers were identified that need to be overcome to
ensure that dialysis patients have the freedom to choose their treatment modality. Education of
patients and patient partners, as well as health care providers, about home dialysis therapy, if
offered at all, is often provided in a cursory manner. Lack of exposure to home dialysis therapies
perpetuates a lack of familiarity and thus a hesitancy to refer p atients to home dialysis therapies.
Patient and care partner support, both psychosocial and financial, is also critical to minimize the
risk for burnout leading to dropout from a home dialysis modality. T hus, the facilitation of home
dialysis therapy will require a systematic change in chronic kidney disease education and the
approach to dialysis therapy initiation, the creation of additional incentives for performing home
dialysis, and breakthroughs to simplify the performance of home dialysis modalities.

home and in-center dialysis, given the training and equipment required, beginning home dialysis
can be a complicated process.
Further, even though PPS payment is the same for home-based and in-center dialysis, providers
may have incentives to prefer in-center dialysis, such as unused capacity.55 According to the
Government Accountability Office (GAO), from 1988 to 2008, the growth in outpatient dialysis
capacity outpaced the growth in the dialysis patient population and, “as a result, dialysis facilities
may have had a greater financial incentive to treat patients in facilities in an effort to use this
expanded capacity.” GAO predicts a realistic goal would be to have 15%-25% of ESRD patients
in home-based dialysis.56
Nephrologist Payments
Nephrologists, physicians who specialize in diseases that affect the kidneys, play a central role in
the treatment of patients with ESRD. Nephrologists diagnose the disease, chart a course of
treatment, provide counseling regarding dialysis and transplant options, and monitor routine
patient care.
Medicare pays nephrologists, and other approved practitioners, a monthly per patient rate for
most outpatient dialysis-related services, which is separate from the ESRD PPS.57 Certain
additional services are bil ed separately to Medicare, in accordance with the Medicare Physician
Fee Schedule. Physicians also bil Medicare separately for training patients to perform home
hemodialysis, self-hemodialysis, and various forms of self-peritoneal dialysis.58
Nephrologist services can be provided in an office or another covered setting, such as a dialysis
facility. For patients receiving treatment in a dialysis facility, the physician payment rate varies
based on the number of patient visits during a month and the ESRD beneficiary’s age. Physicians
and practitioners managing ESRD patients who perform home-based dialysis are paid a single
monthly rate based on the ESRD beneficiary’s age. A physician or practitioner is required to have
at least one face-to-face visit with a home dialysis patient each month.59
Nephrologists work in individual or group practices, in academic settings, or at health care
institutions. Many have long-standing relationships with specific outpatient dialysis facilities
where they refer and monitor patients.60 In addition, there are numerous other administrative and

financial ties between the practitioners and dialysis facilities. Here are some examples from
dialysis provider DaVita’s 2019 Annual Report:
 DaVita contracts with more than 1,000 nephrologists to serve as medical
directors at its dialysis facilities.61 (Medicare has long required that participating
dialysis clinics have medical directors.62)
 DaVita carries out joint ventures in which it owns a majority share of an
outpatient dialysis clinic and nephrologists, hospitals, management services
organizations, or other providers own a minority share. Approximately 26% of
DaVita’s net U.S. dialysis revenues in 2019 came from such joint ventures.63
 DaVita operates a subsidiary, Nephrology Practice Solutions, that provides
recruitment, staffing, and management services to nephrologist practices. The
subsidiary also owns and operates nephrology practices in multiple states.
In addition to these relationships, dialysis providers and physician groups are establishing joint
ventures designed to provide more comprehensive, coordinated care for individuals with kidney
disease. The new models build on existing CMS pilot programs in which practitioners are paid
based on outcomes rather than on the number of services performed.64
Some have expressed concerns about a lack of transparency regarding dialysis joint ventures with
physician groups, amid evidence that patients may be steered to centers in which nephrologists
have a financial interest.65 In 2014, for example, DaVita agreed to pay $350 mil ion to resolve
claims it violated the False Claims Act by paying kickbacks to physicians and physician groups to
induce the referral of patients to its dialysis clinics.66
ESRD Patient Spending and Demographics
In addition to Medicare coverage of dialysis and transplants, many Medicare beneficiaries with
ESRD have other chronic health conditions that require medical care, such as diabetes, heart
disease, or hypertension. According to CMS, the projected per capita monthly cost for a FFS
Medicare enrollee in 2020 is about $1,000. By comparison, the projected FFS per capita monthly
cost for a Medicare beneficiary with ESRD undergoing dialysis is about $8,000.67 Because of

in-hospital consultation as part of their practice. Nephrologists also oversee dialysis units which may be associated with
their own practice, may be free-standing, or affiliated with a hospital.”
61 T he term medical director refers to a physician who oversees the medical care and other specified care and services
in a health care organization or facility.

their higher average costs, Medicare FFS beneficiaries with ESRD account for about 7% of
Medicare FFS spending and make up about 1% of total program enrollment (FFS and MA
combined).
Compared with the overal Medicare FFS population, FFS dialysis patients are disproportionately
younger, non-White, and poor. In 2018, 48% of FFS dialysis patients were dual y eligible for
Medicare and Medicaid, compared with 17% of al FFS beneficiaries, and nearly half were under
the age of 65. Overal , in 2018, 47% of Medicare FFS dialysis beneficiaries were White, 35%

Al items and services covered under original Medicare also are covered by MA plans, except
hospice.71 MA plans also may offer reduced cost sharing or Medicare Part D drug coverage and
supplemental benefits not covered under original Medicare.72
Although the required Medicare benefits are available to MA enrollees just as they are to
enrollees in original Medicare, MA plans and original Medicare differ in terms of payments,
beneficiary costs, and the providers and facilities from whom enrollees can receive care.
 Medicare Payments. There are two different payments to consider:
 Medicare Payments to Plans: Unlike original Medicare, in which CMS
pays medical providers and facilities for each covered item, procedure,
episode, or spel of il ness, CMS pays MA plans a risk-adjusted per
capita monthly amount to provide al required Part A and Part B benefits
to enrollees,73 regardless of the number of services an enrollee uses in a

71 MA plans are required to cover all Medicare required benefits except hospice. If an MA enrollee chooses hospice,
the hospice benefit is paid through original Medicare but the beneficiary remains enrolled in his or her MA plan and
retains access to his or her doctors and supplemental benefits.
72 Except for certain statutorily specified high-cost items and services, cost sharing for items and services under an MA
plan may be higher or lower than cost sharing required under original Medicare. Cost sharing under the MA plan must
be at least actuarially equivalent to cost sharing under original Medicare; however, plans can reduce cost sharing for
items and services as a supplemental benefit under the plan.
73 Risk adjustment compensates plans for the higher expected cost of enrollees who are older or have identified,
underlying health conditions, such as heart disease or diabetes. It also reduces plan payments for the lower expected
cost of enrollees who are younger and healthier.

month. The capitated payment is based on a statutory formula that takes
into account spending in original Medicare.74 (See “Medicare Payments
to MA Plans for ESRD Enrollees.”)
 MA Plan Payments to Providers and Facilities: MA plans negotiate with
medical providers and facilities that join their network (i.e., in-network
providers) to determine the amount the MA plan wil pay the provider or
facility for providing care to plan enrollees; the negotiated payment
amount may differ from the amount paid under original Medicare. If a
plan enrollee receives care from a provider or facility that is outside of
the plan’s network, the provider or facility is paid the amount they would
have received under original Medicare.75 However, the enrollee may be
required to pay al or a portion of that cost, depending on, for example,
whether the care was an emergency or urgently needed care, whether the
beneficiary was directed by his or her network provider to see a non-
network specialist, or whether the plan’s provider network was
inadequate to serve the beneficiary’s needs.76
 Medicare Advantage Premium. Under original Medicare, beneficiaries who
choose to enroll in Part B must pay a monthly premium.77 To be eligible to enroll
in an MA plan, a beneficiary must be eligible for Part A, enrolled in Part B, and
have a plan that serves his or her area. MA enrollees pay the Part B premium but
also may be required by their plan to pay an MA premium. The MA premium
may reflect the plan’s ability to provide required benefits relative to the
maximum amount of payment al owed under the statute, the value of
supplemental benefits, or both.78 (Note that an MA plan may change its premium
from year to year, as discussed in “Considerations for Plan Year 2021 and
Beyond,” below.)
 Out-of-Pocket Costs. Under original Medicare, there is no out-of-pocket (OOP)
cap on beneficiary spending for deductibles, coinsurance, and co-payments. MA
plans have a 2021 maximum OOP limit for in-network service of $7,550.79 MA
plans may offer OOP limits that are lower than this cap. (Note that an MA plan

79 Although many MA plans choose the counties to include in their service areas, one type of MA plan —MA regional
preferred provider organizations (PPOs)—agrees to serve entire regions of states and groups of states, as defined by the
HHS Secretary. T he maximum out-of-pocket (OOP) cap that applies to regional PPO plans (for in - and out -of-network
care) for 2021 is $11,300. Prior to 2021, when calculating maximum OOP limits, CMS did not take into account the
OOP costs of beneficiaries with ESRD; CMS will begin phasing in those expenditures in 2021. T he maximum OOP
cap for all MA enrollees will increase as ESRD expenditures are phased in. See Coleman, HPMS Mem o, p. 6.

may change its out-of-pocket maximum from year to year, as discussed in
“Considerations for Plan Year 2021 and Beyond,” below.)
 Limited Selection of Providers. Under original Medicare, beneficiaries can seek
care from any qualified Part A provider with an agreement to participate in
Medicare or any qualified Part B supplier who accepts assignment on either a
participating or a nonparticipating basis.80 In contrast, an MA enrollee’s choice of
provider may be restricted to those in the plan’s network (see “Background on
Network Adequacy”). Most MA plans are required to develop contracted
networks of health care providers and facilities from which enrollees can receive
benefits. However, enrollees’ ability to seek nonemergency care outside of the
MA network can vary by plan type. For example, PPOs al ow enrollees to receive
nonemergency out-of-network care, usual y with higher cost sharing than in-
network care. MA regional PPO plans—plans that agree to offer coverage to
beneficiaries living in regions designated by CMS—are not required to have
contracted networks of providers to fulfil network requirements in certain areas,
thus providing even greater provider choice in those circumstances.81 (Note that
an MA plan may change its provider network from year to year, as discussed in
“Considerations for Plan Year 2021 and Beyond,” below.)
Medicare Payments to MA Plans for ESRD Enrollees
As mentioned above, Medicare pays private plans a monthly capitated amount to provide al
required Medicare benefits to beneficiaries who enroll in their plans. For non-ESRD enrollees,
the plan payment is determined based on a comparison of each plan’s estimated cost of providing
Medicare covered services (bid) with the maximum amount the federal government wil pay for
providing those services in the plan’s service area (benchmark). If a plan’s bid is less than the
benchmark, the plan’s payment equals its bid plus a rebate, which must be returned to enrollees in
the form of additional benefits, reduced cost sharing, reduced Part B or Part D premiums, or some
combination of these options. If a plan’s bid is equal to or greater than the benchmark, its
payment wil be the benchmark amount and each enrollee in that plan wil pay an additional
premium, equal to the amount by which the bid exceeds the benchmark.
Benchmarks for non-ESRD aged and disabled enrollees are calculated as a percentage of per
capita spending by beneficiaries in FFS Medicare. The percentages are 95%, 100%, 107.5%, or
115%, with higher percentages applied to counties with lower FFS spending. For example, the

80 A Medicare participating physician or practitioner agrees to accept assignment for all Medicare beneficiaries for
whom they provide services and acknowledges the Medicare payment amount, including coinsurance, as payment in
full. Non-participating physicians or practitioners may choose to accept assignment on a service-by-service basis and
are allowed limited balance billing above a reduced Medicare payment amount.
81 42 C.F.R. §422.112(a)(ii) allows MA regional plans, with CMS approval, to meet network ade quacy requirements
using methods other than contracted providers. “A regional PPO may establish a network that meets the statutory
network adequacy requirements throughout 85% of a region. In that part of the region, the plan may charge higher cost
sharing for out -of-network services. But in the part of the region without a network, the plan cannot charge higher cost
sharing for out -of-network services.” MedPAC, Report to Congress: Issues in a Modernized Medicare Program , June
2005, p. 64, at http://www.medpac.gov/docs/default-source/reports/June05_ch3.pdf?sfvrsn=0. As of September 2020,
most MA enrollees were in a local coordinated care plan, such as a local health maintenance organization or a local
PPO (95.0%). Regional PPO enrollees make up 4.7% of all MA enrollment, and private fee -for-service enrollees
(0.3%) and medical savings account enrollees (0.03%) make up the remaining enrollment. See CMS, “Monthly
Contract and Enrollment Summary Reports,” at https://www.cms.gov/Research-Statistics-Data-and-Systems/Statistics-

MA Coverage of ESRD and Network Requirement Changes

25% of counties with the lowest FFS spending receive the highest percentage (115%) of per
capita FFS as their MA benchmark. The 25% of counties with the highest FFS spending receive
the lowest percentage (95%) of per capita FFS. Benchmarks may be increased for high-quality
plans, with quality measured by a five-star rating system. Overal , benchmarks are subject to a
limit based on the level of benchmarks calculated using the methodology that applied prior to the
Patient Protection and Affordable Care Act (P.L. 111-148). Final y, payments (after the bid and
benchmark comparison) are risk adjusted to account for the higher cost of older or sicker
beneficiaries and the relatively lower cost of younger or healthier beneficiaries.
Payments to MA plans for ESRD enrollees using dialysis are not determined based on bids and
benchmarks, as described above.82 Instead, Medicare payments for enrollees using dialysis are, in
general, based on 100% of the statewide per capita spending for beneficiaries on dialysis in FFS
Medicare, risk adjusted by an ESRD risk adjustment model for enrollees undergoing dialysis. MA
beneficiaries with ESRD pay the same plan premiums as those without ESRD who are enrolled in
the same plan. ESRD payments are not adjusted by plan quality.
ESRD Enrollment
In 2019, 532,000 Medicare enrollees with ESRD had Medicare Part A benefits. Of those
beneficiaries, 401,000 were in original Medicare and 131,000 were in Medicare private plans,
equating to MA enrollment of about 25% of al ESRD beneficiaries.83 By comparison, about 39%
of al Medicare beneficiaries were enrolled in MA plans in 2020.84
The lower MA enrollment reflects, in part, long-standing policies that have prevented ESRD
beneficiaries from joining MA plans. Currently, Medicare beneficiaries with ESRD may be
enrolled in MA plans only if the beneficiaries
 developed ESRD while already enrolled in an MA plan;
 developed ESRD while receiving health benefits through the same organization
(such as an employer group health plan) that offers the MA plan;
 had a kidney transplant and no longer require dialysis but are entitled to
Medicare due to age or disability; or
 have an ESRD Medicare Special Needs Plan (SNP) in their geographic area. A
SNP is an MA plan that exclusively enrolls, or enrolls a disproportionate
percentage of, special needs individuals, such as those with severe or disabling
chronic conditions.85
An ESRD beneficiary who is enrolled in an MA plan that is later discontinued has a one-time
right to join another MA plan.

82 Medicare payments to plans vary by dialysis status, with a different payment and risk -adjustment model for enrollees
using dialysis, those who have had a recent transplant, and those with a functioning transplant. For more information,
see RT I International, Report to Congress: Risk Adjustm ent in Medicare Advantage, December 2018, p. 30, at

83 CMS, “Medicare Program,” 85 Federal Register 33886. Not all Medicare private plans are considered MA plans. For
example, plans paid by Medicare based on the cost of services used by the enrollees or based on demonstration
authority are not considered MA plans.

Patient advocates and lawmakers have said ESRD patients, with their more complex medical
conditions and comorbidities, could benefit from joining MA plans.86 MA plans, for example, are
required to ensure continuity of care and integration of services, including offering each enrollee
a primary care provider, implementing programs for coordinating plan services with community
and social services available in the area, and developing systems to address enrollee barriers to
prescribed treatments and regimens.87
As mentioned above, unlike FFS Medicare, MA plans are subject to annual enrollee OOP caps,
which could be particularly beneficial for ESRD beneficiaries under the age of 65 who have high
medical costs. (See also “Considerations for Plan Year 2021 and Beyond,” below.) Some
Medicare beneficiaries may have an alternative option for a plan with an OOP spending cap—a
Medigap policy—that might not be available to al ESRD beneficiaries. FFS Medicare
beneficiaries over the age of 65 have a guaranteed right to purchase supplemental Medigap
coverage, which provides additional protection from high OOP costs, such as annual deductibles
or cost sharing.88 By contrast, there is no general federal requirement that insurers sel Medigap
plans to Medicare beneficiaries under the age of 65 who qualify for Medicare based on disability,
including those with ESRD. However, according to the Department of Health and Human
Services (HHS), 33 states require insurers to offer at least one type of Medigap policy to
Medicare beneficiaries under the age of 65.89 Some insurers voluntarily sel Medigap plans to
younger Medicare enrollees, even when there is no state requirement to do so. If permitted by
state law, insurers may use medical underwriting and charge higher premiums for Medigap plans
when sel ing to those under the age of 65, which could make the plans cost-prohibitive for
younger ESRD patients.
Although MA care coordination and limits on OOP spending may be attractive features for ESRD
beneficiaries, MA plans often have contracted networks of providers from whom enrollees
receive care. As such, MA enrollees may have access to a more limited number of physicians,
dialysis centers, and other health care providers than FFS beneficiaries.
Background on Network Adequacy
In general, MA plans are required to develop contracted networks of medical providers and
facilities from whom their enrollees can receive covered benefits. Though MA plans may limit
the number of providers and facilities in their network, the network must be sufficient to ensure
required Medicare benefits are available and accessible to each enrollee with reasonable
promptness and are consistent with community standards of care, taking into account the number
and distribution of providers in a geographic area and other factors that CMS determines

appropriate.90 In short, “the plan must ensure that contracted providers are distributed so that no
enrollee residing in the service area must travel an unreasonable distance to obtain covered
services.”91
Over the years, CMS has developed an automated, objective process to evaluate network
adequacy based on criteria such as the number and location of specified provider and facility
types. CMS has issued specific network criteria as sub-regulatory guidance, which is general y
followed by plans but does not have the legal force of a regulation.92
For plan year 2020, to meet network adequacy criteria, MA plans must contract with both (1) a
minimum number of providers and facilities for each specified specialty/type and (2) a sufficient
number of specified providers and facilities to ensure that 90% of beneficiaries residing in a
county have access to at least one of each type of provider and facility within set maximum time
and distance standards.93 The maximum time and distance standards vary by provider and facility
type and by county type; county types are defined as counties that are part of (1) large metro
areas, (2) metro areas, (3) micro areas, (4) rural areas, as wel as (5) counties with extreme access
considerations (CEAC), al of which are based on population size and density (see Table 2).94
Nephrologists and outpatient dialysis facilities are included in the specified network criteria. For
example, for 2020, MA plans must contract with a sufficient number of outpatient dialysis centers
such that 90% of beneficiaries in a rural county in their service area have access to a center within
55 minutes or 50 miles from their home. Maximum time and distance standards are shorter for
metro or large metro areas and longer for CEACs, as shown in Table 2.95 Under a CMS
exceptions process, a plan may request new criteria if it cannot meet the published criteria in a
particular area due to a provider or facility shortage.96
The Medicare Payment Advisory Commission (MedPAC) found the maximum distance criteria
for MA network adequacy for dialysis centers exceeded the typical travel distances that new
ESRD beneficiaries in FFS Medicare traveled to obtain dialysis for most types of counties. When
calculating driving distances of new FFS dialysis beneficiaries, MedPAC found the median
distance to be 6 miles and the 25th and 75th percentiles to be approximately 3 miles and 13 miles,
respectively. Beneficiaries in rural counties traveled farther than those in urban areas (with
median travel distances of approximately 11 miles and 5.5 miles, respectively.) According to

93 It may be the case that after the minimum number criteria are met, additional providers or facilities must be added to
the network to fulfill the maximum time and distance criteria.
94 CMS created county size designations based on “approaches used by the United States Census Bureau in its

MedPAC’s findings, “the maximum distance standard applied for MA network adequacy is 10
miles for large metro areas. For al other areas, maximum distance standards range from 30 to 90
miles. Although the network adequacy distance standard is a maximum, it is worth noting that the
standard for areas (other than large metro areas) vastly exceeds the range of distances commonly
traveled for dialysis in FFS Medicare.”97

MA Program Changes Related to ESRD in the 21st
Century Cures Act
The Cures Act requires that, starting in 2021, individuals who qualify for Medicare on the basis of
ESRD—rather than on the basis of age—be al owed to enroll in MA plans. Recognizing the
higher average cost of ESRD beneficiaries as compared with other Medicaid beneficiaries, and to
more accurately pay plans for enrollees with ESRD and CKD, the Cures Act included special
provisions pertaining to ESRD and CKD:98
 Kidney Acquisition Costs. Instead of requiring MA plans to pay for the high
costs associated with kidney acquisition, including Medicare-covered expenses
for a kidney donor, from the MA plan’s capitated payment, the Cures Act
requires that kidney acquisition costs be paid by FFS Medicare. The Cures Act
also requires the HHS Secretary to remove the estimated cost of kidney
acquisition from al MA payments, which means reducing the per capita FFS

spending estimate used in the benchmark for aged and disabled beneficiaries and
the ESRD payment rates starting in 2021.99
 Kidney Disease-Related Risk Adjustment. The HHS Secretary must evaluate
the impact of adding CKD variables to the MA risk-adjustment model for aged
and disabled beneficiaries. Any subsequent changes to the model are to be phased
in by 2022, which may result in higher payments for sicker beneficiaries.100
 Quality Ratings. The HHS Secretary must evaluate whether the current MA
quality rating system should be adjusted to account for ESRD enrollees. Plan
quality ratings are displayed on Medicare.gov to assist beneficiaries when
deciding whether to enroll in an MA plan or which plan to choose. In general,
high-quality ratings also may increase benchmarks used to determine plan
payments for aged and disabled enrollees. However, MA plan payments for
ESRD enrollees are not adjusted by plan quality.
CMS projects that ESRD enrollment in MA plans wil increase by 83,000 due to the Cures Act
changes. The increase is assumed to take place over six years, although half of the additional
beneficiaries (41,500) are expected to enroll in MA plans in the first year, 2021.101 In spite of the
payment and risk-adjustment changes in the Cures Act, MA plans have expressed concern about
whether they wil receive sufficient compensation for the more expensive ESRD patients.102 As
discussed in the next section, health plans’ concerns are based on the level of CMS payments,103
as wel as “rising dialysis costs given little competition in a market dominated by DaVita and
Fresenius.”104
MA Plan Concerns About ESRD Payments and Dialysis Provider
Competition
Recent insurer-sponsored analyses suggest MA payments for ESRD enrollees undergoing dialysis
fal short of the cost of serving these beneficiaries. By one estimate, for some MA plans, the cost
of serving ESRD enrollees exceeds premium income (i.e., Medicare payment and beneficiary
premiums) by 12%.105 This loss may be due, in part, to how the OOP cap is calculated. CMS sets
the maximum OOP cap at the 95th percentile of projected beneficiary OOP spending for the year
($7,550 for 2021). This means that 95% of beneficiaries in original Medicare have projected OOP
spending that wil be below $7,550 in 2021. However, CMS “has not traditional y used out-of-

pocket spending data for beneficiaries with diagnoses of ESRD in this process.”106 Because of
ESRD beneficiaries’ very poor health, they have much higher spending than non-ESRD
beneficiaries. As a result, whereas 5% of a plan’s non-ESRD enrollees likely would reach the
OOP maximum in a year and stop paying cost sharing for subsequent care, al or nearly al of a
plan’s ESRD enrollees likely would reach the OOP maximum in a year and stop paying cost
sharing on subsequent care. When a beneficiary reaches the OOP maximum, the plan—rather
than the beneficiary—must pay for subsequent care. As CMS sets the OOP maximum, plans
attempting to recoup any losses may look to increasing premiums or reducing supplemental
benefits for al enrollees. CMS plans to begin incorporating ESRD spending data into the OOP
cap calculation starting in 2021.
The authors of the study cited above suggest that another possible reason for the 12% loss on
each ESRD enrollee is plans’ ability or inability to negotiate favorable payment rates to dialysis
providers that they must have in their plan networks.107 In developing their provider networks,
MA plans, in general, must contract in or near the plan’s service area with providers and facilities
that wil serve their enrollees. The terms of those contracts, which include the amounts plans
agree to pay for services and, correspondingly, the amounts providers and facilities are wil ing to
accept for providing those services, are negotiated between each MA plan, on the one side, and
each provider or provider group and each facility or health system, on the other.108 Negotiations
may start with the payment amount provided under original Medicare (such as the ESRD PPS),
but reimbursement may be raised or lowered depending on the conditions in the local market and
which party—the plan or the provider/facility—has a stronger bargaining position. However,
although there have been studies examining MA payments to network hospitals and the degree to
which those rates are greater or less than rates under FFS Medicare, a comparable analysis of MA
rates to outpatient dialysis centers is not available.109
Final Rule for 2021 Enrollment of ESRD Beneficiaries in MA Plans
with Respect to Network Requirements
On June 2, 2020, CMS issued a final rule setting a number of MA requirements for CY2021. This
final rule included regulations governing kidney acquisition costs, risk adjustment, and other
issues related to the ESRD transition, including network adequacy.
As part of the final rule, CMS codified its existing sub-regulatory guidance on network adequacy,
with some exceptions. The sub-regulatory guidance on network adequacy included a list of
provider specialty and facility types subject to network adequacy reviews—including (a)
requirements for a minimum number of providers/facilities and (b) set maximum time and

108 Regulations limit the amount of provider payments that can depend on meeting specified goals (42 C.F.R.
§422.208).
109 A recent analysis aggregating nationwide data found that MA plans pay 5.6% less than FFS for hospital services,
after accounting for hospital network, geographic area, and case mix. However, this finding may differ substantially
based on the specific conditions of a particular market. See Laurence C. Baker et al., “Medicare Advantage Plans Pay
Hospitals Less T han T raditional Medicare Pays,” Health Affairs, vol. 35, no. 8 (August 2016), p. 1444. Additionally, a
Congressional Budget Office (CBO) analysis examined average MA payment rates paid by three large insurance
carriers to hospitals for 200 metropolitan statistical areas (MSAs). CBO foun d that average MA plan payments in the
MSA at the 90th percentile of the distribution were 6% higher than the average FFS rate and that the average MA rate in
the MSA at the 10th percentile of the distribution was 2% below the average FFS rate. CBO, An Analysis of Private-
Sector Prices for Hospital Adm issions, 2017-02, April 2017, p. 2, at https://www.cbo.gov/publication/52567.

distance standards. The sub-regulatory guidance also included an exceptions policy if it was
impossible for a plan to meet the adequacy standards.
Going forward, MA plans stil must contract with a minimum number of providers and facilities
of each specified specialty and type. However, the rule loosened criteria for maximum time and
distance standards. Under the rule, in micro, rural, and CEAC counties, starting in 2021, plans are
required to contract with a sufficient number of providers and facilities to ensure that 85% of
beneficiaries (rather than the current 90%) have at least one provider/facility type within
published maximum time and distance standards. The rule also al owed a 10 percentage point
“credit” toward meeting the time and distance criteria for plans that established telehealth
contracts with specified provider types, including nephrologists. Further, the rule al owed an
additional 10 percentage point credit for plans serving states with laws that limit health care
facility competition.110 The credits for contracting with telehealth providers and for serving states
that limit health care facility competition can be applied together; if both credits apply, an MA
plan would be required to contract with a sufficient number of providers and facilities to ensure
that 65% of beneficiaries in micro, rural, or CEAC counties and 70% of beneficiaries in metro or
large metro areas have at least one provider/facility type within published maximum time and
distance standards. Though the rule did not change the maximum time and distance standards, it
al owed plans to require a larger percentage of potential enrollees to travel farther for in-network
Medicare-covered care.
Of particular focus to the ESRD community, the final rule did not include outpatient dialysis
facilities on the list of providers subject to time and distance criteria. Instead, CMS wil require
MA plans to attest they have adequate networks of such providers. CMS said the policy change
was designed to encourage MA plans to offer more choices for ESRD patients undergoing
dialysis, including home dialysis. CMS also noted that MA plans are required to cover services at
an out-of-network provider when network providers are unavailable or inadequate to meet an
enrollee’s medical needs. When a beneficiary receives care from an out-of-network facility
because a network facility is not available or unable to meet the beneficiary’s needs, the
beneficiary pays the in-network cost sharing and the MA plan pays the facility the amount it
would have received if the beneficiary were in original Medicare, an amount that could be lower
than the MA plan’s contracted rates.111
Stakeholder and Support Agency Positions and Reactions to the Rule
The proposed rule and publication of the final rule spurred controversy and a court chal enge, as
MA plans, dialysis providers, and patient groups reached different conclusions about the rule’s
potential impact.

110 State Certificate of Need (CON) laws, for example, require a hospital to demonstrate need in the community before
it can expand or build a new hospital. Limiting the number of hospitals or facilities in an area may make it more
challenging for MA plans to develop contracted networks in those areas, because there are fewer hospi tals to negotiate
with. CMS, in the final rule, indicated that, “CON laws restrict the supply and competition for healthcare services and
increase costs.... When MA organizations must pay more for benefits as the research demonstrates happens when there
are fewer providers or facilities with which to contract, that reduces access to benefits offered by MA organizations.”

MA Plans
MA plan sponsors told CMS their plans already had been taking a financial loss on each ESRD
enrollee. According to the plan sponsors, overal , the proposed changes in payment for ESRD
beneficiaries to comply with the Cures Act would not adequately account for the increased costs
of the new ESRD enrollees, and the expected influx of new enrollees in 2021 could pose a large
burden. Plans indicate that inadequate payments for ESRD enrollees could force them to set
higher premiums, increase OOP limits (up to the CMS-specified maximum), or reduce
supplemental benefits for al enrollees.112
However, MA plan sponsors told CMS the changes in network adequacy requirements (switching
from measuring only outpatient dialysis to determine access to dialysis services to requiring an
attestation that enrollees have access to dialysis services, whether through outpatient clinics or
home dialysis) could improve their financial position. This change could increase plans’ ability to
negotiate discounts with outpatient dialysis providers, thus reducing their cost of providing
dialysis benefits to ESRD enrollees. One of the insurer-funded studies noted above said relaxing
MA network adequacy requirements for dialysis-related services could “potential y facilitate
increased provider competition to perform these types of services.”113 The report did not provide
detailed information on expected savings or the time period for realizing major shifts in dialysis
delivery from outpatient to home-based dialysis. Further, home dialysis may be an imperfect
substitute for outpatient dialysis care for a portion of Medicare beneficiaries, making it unclear
the extent to which greater network flexibility to substitute in-home care for outpatient dialysis
care wil actual y increase competition. The outlook is further complicated by the fact that the two
largest outpatient dialysis providers, DaVita and Fresenius, are also the main providers of home-
based dialysis services.
Dialysis Providers
Fresenius, in a comment letter on the proposed rules, stated, “We urge CMS to consider, however,
that weak network adequacy standards wil not lead to reductions in the total c ost of care. Rather,
weak standards wil result in plan design that discriminates against beneficiaries with ESRD.”114
Nephrologists
In a comment letter to CMS on the proposed rule, the American Society of Nephrologists (ASN)
encouraged CMS to “avoid a wholesale removal of time and distance protections.” The group
added that ESRD patients and physicians were in the midst of significant changes in care
delivery, including new CMS pilot programs, more innovative dialysis equipment, expanded
telehealth, and new providers. According to ASN,
In such a dynamic environment, it seems logical to ASN that network adequacy in the
future might be achieved differently than it was in the past … While ASN does not advocate
for CMS to eliminate these standards for the entire kidney patient population, ASN would

welcome the opportunity to dialogue with the agency over what might constitute network
adequacy in the future, particularly regarding home dialysis patients.115
Patient Groups
In comments on the proposed rule, patient groups expressed concern about how MA plans may
respond to removing outpatient dialysis centers from the list of facilities subject to automated
quantitative assessment of network adequacy. Patient groups expressed concern that it would
incentivize MA plans to drop outpatient dialysis centers, including centers that beneficiaries are
accustomed to using, in favor of in-home dialysis, which is not an option for certain beneficiaries,
such as those with housing insecurity or a lack of caregiver support. The patient groups noted that
this change could discourage ESRD beneficiaries from enrolling in MA plans, depending on how
individual plans set up their provider networks.116
On June 24, 2020, a dialysis patient group (Dialysis Patient Citizens, or DPC) filed suit in federal
court to halt the rule on the grounds it discriminated against patients who needed outpatient
dialysis.117 The group said the rule treats ESRD patients differently than other beneficiaries by not
holding MA plans to the same network adequacy standards (i.e., the time and distance standards)
that apply to other provider specialty and facility types that treat beneficiaries with other diseases.
The group also disagreed with CMS’s assertion that it is sufficient that MA plans attest to the
adequacy of their dialysis networks, noting that CMS has required other providers in MA plan
networks to meet the objective, quantitative measures of network adequacy.118
In addition, DPC said the rule is particularly worrisome given the low health and economic status
of the ESRD population. In its lawsuit, DPC noted that ESRD patients “are some of the most
vulnerable people in the country. Many are of extremely limited means, and many are
minorities.… The disease exacerbates patients’ vulnerability because dialysis is very expensive,
and the length and frequency of treatment commonly impedes continued employment.”119
The ongoing COVID-19 pandemic also heightens concerns about potential disruptions in dialysis
care, as ESRD patients begin enrolling in MA plans for 2021. The pandemic has made it more
difficult for patients to receive routine dialysis, as outpatient clinics have implemented new
protective protocols, grappled with shortages of personal protective equipment, and dealt with
il ness among their staff. In addition, 20%-30% of individuals hospitalized for COVID-19

“[Dialysis Patient Citizens] emphasized [in its comments on the proposed rule] that home-dialysis patients are
disproportionately White and affluent, while in-center [outpatient] dialysis patients are disproportionately black or
Hispanic and are more likely to live in an economically disadvantaged zip code, be unemployed, and be uninsured or
on Medicaid.” SSA §1852(b)(1) and §1557 of the Patient Protection and Affordable Care Act ( P.L. 111-148) prohibit
discrimination, including establishment of plan designs or benefits that would discourage certain MA -eligible
individuals from enrolling in the plan.

Certain other Medicare required services are not subject to the quantitative network adequacy standards, such as home
health care, durable medical equipment, and transplant centers. However, these may not be comparable examples
relative to dialysis centers, either because caregivers and suppliers deliver care or equipment to the beneficiaries in their
homes rather than requiring beneficiaries to travel for items or services o r because a beneficiary travels to a location for
a single procedure rather than frequent, ongoing treatments.

develop kidney-related issues, some requiring dialysis, according to the American Society of
Nephrology, which has led to a surge in demand for dialysis services and increased stress on
supplies.120
Medicare Payment Advisory Commission
MedPAC, in response to the proposed rule, pointed out that beneficiaries with ESRD need access
to both nephrologists, to manage their ESRD, and dialysis centers. A MedPAC analysis found that
a significant share of nephrologists refer patients to dialysis facilities owned by single companies,
which is said may be a response to industry consolidation—with a few companies controlling
most facilities—or because a nephrologist may have a joint venture with a specific dialysis
provider. MedPAC posits that an MA plan attempting to discourage ESRD enrollment could
contract with nephrologists who refer patients exclusively to centers owned by one dialysis
company and then contract with a different dialysis provider to meet dialysis network adequacy
standards. Doing so would discourage beneficiaries with ESRD from enrolling in that MA plan,
as they would not be able to continue to use both their nephrologist and their preferred dialysis
center. According to MedPAC, “such practice should be considered discriminatory and should be
barred.”121 The issue was not addressed by the Administration in the final rule.
Considerations for Plan Year 2021 and Beyond
Medicare beneficiaries and MA enrollees have an opportunity to assess MA plan options
available to them during open enrollment season, which runs from October 15 through December
7 of each year, for plan choices effective for the following year.122 Each year, MA plans may
change aspects of their offerings, such as premiums, deductibles, cost sharing, out-of-pocket
maximums, drugs included on their formularies, and providers and medical facilities in their
networks, among other factors. As a general rule, it is advisable for beneficiaries to reassess their
MA plans for changes in the upcoming year, if they already are enrolled in an MA plan, and to
compare the updated plan to other available plan options. A beneficiary’s plan may have changed
so that it is no longer the best option.
Comparison of MA plans—as wel as comparison of non-MA options, such as original Medicare
plus a private Medigap policy, if available—can be chal enging. When evaluating options,
beneficiaries may consider factors such as (1) their own use of medical services over a previous
period and whether their health care use is likely to change; (2) the cost sharing associated with
the health care they expect to use and, if possible, the likelihood of unexpected additional health
care needs; (3) their use of prescription drugs and the costs associated with them; (4) the size of
any MA or Medigap monthly premium; and (5) the level of the out-of-pocket MA or Medigap cap
and whether their spending is likely to reach it.
To aid in the task of assessing MA plans, beneficiaries have access to several sources of
information. Medicare beneficiaries are mailed a Medicare &You handbook,123 which describes

the program and MA options available in their area and includes information about the original
Medicare program, with expected premiums and cost sharing. Other sources of information
include the “Medicare Compare” tool on the Medicare.gov website, where beneficiaries can
compare several plan options side-by-side; the Medicare “Out of Pocket Cost Estimator” may
facilitate that calculation.124 Agents and brokers may offer education or marketing events.125 In
addition, the State Health Insurance Assistance Program provides free, one-on-one health
insurance counseling for seniors.126
Although several sources of information are available to beneficiaries, research indicates
beneficiaries tend to invest a great deal of energy comparing their options the first time they
enroll in an MA plan but feel daunted by the prospect of repeating the exercise in subsequent
years.127 Many beneficiaries find it frustrating to compare plans due to the volume of available
information or, in the case of the Medicare Compare tool, the difficulty in using available tools to
find the information they want. More than a third of beneficiaries indicated that comparing
Medicare plans was very or somewhat difficult, and a higher percentage (44%) of those in fair or
poor health felt the same way.128 As such, many may rely on insurance agents, family, friends,
doctors, or pharmacists to provide recommendations. Whether by choice or inertia, the majority
of beneficiaries do not voluntarily switch plans. Between 2007 and 2016, the percentage of
beneficiaries choosing to switch plans in any particular year was between 6% and 11%.129 A
beneficiary who finds, after the start of the year, that his or her MA plan changed in an
unanticipated way, such as a change in cost sharing, has an opportunity to switch to a different
MA plan during the first three months of each calendar year. After Mach 31, enrollees must
remain in their MA plans, barring eligibility for a special enrollment period.130
Plan Netw orks
If a beneficiary enrolls in an MA plan, certain aspects of the plan must remain the same
throughout the calendar year, such as the monthly premium or specified cost sharing. However,
an MA plan’s provider network may change during a plan year. An MA plan is al owed to drop a
provider from its network at any time, or the plan may be unable to come to an agreement with a
provider over renewing a contract for continued network participation. As discussed, each MA
plan is required to have a sufficient number of contracted providers to ensure access to services
with reasonable promptness and in a manner that ensures continuity of benefits, consistent with

“the prevailing community pattern of health care delivery in the area.”131 That requirement does
not guarantee, however, that a beneficiary wil have access to the physician or facility of his or
her choice. Even if a beneficiary specifical y enrolled in a plan because his or her nephrologist
and preferred dialysis center were both in the network, there is no guarantee both provider and
center wil remain in the network the entire year. Moreover, analyses by the HHS Office of
Inspector General found that almost half (47.7%) of the MA provider directories examined
contained inaccuracies, such as incorrect phone numbers, providers not practicing at the location
listed, or providers no longer taking new patients when they were listed as accepting new
patients.132 Such inaccuracies can further complicate beneficiaries’ attempts to enroll in plans
with their choice of providers. As noted above, beneficiaries may switch to a different MA plan
during the first three months of each calendar year but after that must remain in their MA plan,
barring eligibility for a special enrollment period.133
Monitoring Access to Providers
In the final rule, CMS cited two methods for monitoring whether beneficiaries are able to access
needed care.134 First, several measures of access to care are included in the calculation of plan
quality, as measured through a five-star rating system used for beneficiary education. MA plans
that perform wel on the quality metrics also are eligible for increased Medicare payments. The
star rating measures include a beneficiary’s ease at getting needed care and seeing specialists, as
wel as getting appointments and care quickly. Data for implementing the star measures are
captured through the annual Consumer Assessment of Healthcare Providers and Systems
(CAHPS) survey. However, the CAHPS survey that might identify problems with access to
dialysis services in CY2021 wil not be fielded until the beginning of CY2022, and results wil
not be reported until the fal of CY2022; this method may be too slow to assist an ESRD patient
who is having trouble securing the necessary thrice-weekly dialysis appointments at an in-
network dialysis center.
The second method cited by CMS for monitoring ESRD enrollees’ access to care is through the
Complaint Tracking Module (CTM). Each beneficiary who cal s 1-800-Medicare with a
complaint about his or her MA plan is to be logged into the CTM. In the final rule, CMS
indicated that it “ensure(s) access to al Medicare covered services through monitoring and
investigating complaints in the CMS Complaint Tracking Module.”135 CMS is to “monitor and
investigate complaints related to access concerns and work with [CMS] regional office
caseworkers to resolve issues with the MA plans.”136
Enrollee Appeals to Plans to Receive Care from an Out-of-Network Provider
In the final rule, CMS reiterated the regulatory requirement for MA plans to arrange out-of-
network specialty care for an enrollee if network providers are unavailable or inadequate to meet

131 SSA §1852(d)(1) and 42 C.F.R. §422.112(a)(10).

the enrollee’s needs.137 Further, CMS indicated that, “if network providers are incapable of
meeting the enrollee’s medical needs because the burden of travel to the in-network dialysis
center is inconsistent with the prevailing community pattern of health care delivery in the area,
the MA plan must arrange for care outside of the network and at in-network cost-sharing in order
to meet the MA plan’s obligation under the MA program rules to furnish covered services.”138
The beneficiary, or the beneficiary’s representative or doctor, can file an organization
determination to receive approval for the care. If the care is denied, that decision can be
appealed.139
Beyond 2021
It is unclear whether—or how quickly—MA plans could respond to the regulatory changes in MA
network adequacy requirements. Final decisions on dialysis network changes may depend, in
part, on whether—or how quickly—MA plans can expand capacity to provide in-home dialysis
care or secure lower prices for outpatient care from dialysis chains. It also remains to be seen
whether ESRD beneficiaries wil find MA plans an attractive option for 2021 or for subsequent
years.
