Medicare and Budget Sequestration
January 25, 2021
Sequestration is the automatic reduction (i.e., cancellation) of certain federal spending, generally
by a uniform percentage. The sequester is a budget enforcement tool that was established by
Patricia A. Davis
Congress in the Balanced Budget and Emergency Deficit Control Act of 1985 (BBEDCA, also
Specialist in Health Care
known as the Gramm-Rudman-Hollings Act; P.L. 99-177, as amended) and was intended to
Financing
encourage compromise and action, rather than actually being implemented (also known as

triggered). Generally, this budget enforcement tool has been incorporated into laws to either
discourage or encourage certain budget objectives or goals. When these goals are not met, either

through the enactment of a law or the lack thereof, a sequester is triggered and certain federal
spending is reduced.
Sequestration is of recent interest due to its current use as an enforcement mechanism for three budget enforcement rules
created by the Statutory Pay-As-You-Go Act of 2010 (Statutory PAYGO; P.L. 111-139) and the Budget Control Act of 2011
(BCA; P.L. 112-25). At present, only the BCA mandatory sequester has been triggered. Under the BCA, the sequestration of
mandatory spending was originally scheduled to occur in FY2013 through FY2021; however, subsequent legislation,
including, most recently, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act; P.L. 116-136), extended
sequestration for mandatory spending through FY2030. (The CARES Act, as amended by the Consolidated Appropriations
Act, 2021 [P.L. 116-260], also temporarily suspended the application of this sequestration to Medicare from May 1, 2020,
through March 31, 2021.) The Statutory PAYGO sequester and BCA discretionary sequester are current law and can be
triggered if associated budget enforcement rules are broken.
Medicare is a federal program that pays for certain health care services of qualified beneficiaries. The program is funded
using both mandatory and discretionary spending and is impacted by any sequestration order issued in accordance with the
aforementioned laws. Medicare is mainly impacted by the sequestration of mandatory funds since Medicare benefit payments
(the majority of Medicare expenditures) are considered mandatory spending. Special sequestration rules limit the extent to
which Medicare benefit spending can be reduced in a given fiscal year. This limit varies depending on the type of
sequestration order.
Under a BCA mandatory sequestration order, Medicare benefit payments and Medicare Integrity Program spending cannot be
reduced by more than 2%. Under a Statutory PAYGO sequestration order, Medicare benefit payments and Medicare Program
Integrity spending cannot be reduced by more than 4%. These limits do not apply to mandatory administrative Medicare
spending under either type of sequestration order. These limits also do not apply to discretionary administrative Medicare
spending under a BCA discretionary sequestration order.
Generally, Medicare’s benefit structure remains unchanged under a mandatory sequestration order and beneficiaries see few
direct impacts. However, Medicare plans and providers see reductions in payments. Due to varying plan and provider
payment mechanisms among the four parts of Medicare, sequestration is implemented somewhat differently across the
program.

Medicare and Budget Sequestration

Introduction
Sequestration is the automatic reduction (i.e., cancellation) of certain federal spending, generally
by a uniform percentage.1 The sequester is a budget enforcement tool that Congress established in
the Balanced Budget and Emergency Deficit Control Act of 1985 (BBEDCA, also known as the
Gramm-Rudman-Hollings Act; P.L. 99-177, as amended) intended to encourage compromise and
action, rather than actually being implemented (also known as triggered).2 Generally, this budget
enforcement tool has been incorporated into laws to either discourage or encourage certain budget
objectives or goals. When these goals are not met, either through the enactment of a law or lack
thereof, a sequester is triggered and certain federal spending is reduced.
Sequestration is of recent interest due to its current use as an enforcement mechanism for three
budget enforcement rules created by the Statutory Pay-As-You-Go Act of 2010 (Statutory
PAYGO; P.L. 111-139) and the Budget Control Act of 2011 (BCA; P.L. 112-25). Currently, only
the BCA mandatory sequester has been triggered and is in effect (with the exception of May 2020
through March 2021 for Medicare).3 However, the Statutory PAYGO sequester and the BCA
discretionary sequester are current law and can be triggered if the budget enforcement rules are
broken.
Medicare, which is a federal program that pays for covered health care services of qualified
beneficiaries,4 is subject to a reduction in federal spending associated with the implementation of
these three sequesters, although special rules limit the extent to which it is impacted.
This report begins with an overview of budget sequestration and Medicare before discussing how
budget sequestration has been implemented across the different parts of the Medicare program.
Additionally, this report provides appendixes that include references to additional Congressional
Research Service (CRS) resources related to this report and budget terminology definitions, as
defined by BBEDCA.
Budget Sequestration
Under current law, sequestration is a budget enforcement tool that occurs because certain
budgetary goals have not been met. When a sequester is triggered, all applicable budget accounts,
unless exempted by law, are reduced by a certain percentage amount for a fiscal year.5 The

1 Under the Balanced Budget and Emergency Deficit Control Act of 1985 (BBEDCA; also known as the Gramm-
Rudman-Hollings Act; P.L. 99-177) §250(c)(2), sequestration is defined as “the cancellation of budgetary resources
provided by discretionary appropriations or direct spending law.” Budgetary resources are subject to sequestration
unless exempted by law. See Office of Management and Budget (OMB), OMB Circular A-11 (2019), Section 100, at
https://www.whitehouse.gov/wp-content/uploads/2018/06/s100.pdf.

Honorable Phil Gramm, 112th Cong., 1st sess., May 4, 2011.
3 §3709 of the Coronavirus Aid, Relief, and Economic Security Act (CARES Act; P.L. 116-136) temporarily suspended
the application of the Budget Control Act of 2011 (BCA; P.L. 112-25) sequestration to Medicare from May 1, 2020,
through December 31, 2020. The Consolidated Appropriations Act, 2021 (P.L. 116-260), amended the CARES Act to
extend this suspension through March 31, 2021.

5 Sequestration does not apply to every account, since many budget accounts are either exempted from sequestration or
governed by special rules under sequestration, the latter of which can vary depending on the sequestration trigger. See
BBEDCA §255 and §256, as amended. Since OMB is responsible for the execution and legal interpretations of
sequestration orders, some accounts not listed in these sections may also be exempt from sequestration. For a complete
list of exempted accounts, see CRS Report R42050, Budget “Sequestration” and Selected Program Exemptions and

Medicare and Budget Sequestration

percentage reduction varies between and within budget accounts depending on the categories of
funding, as described below, contained within each budget account.
After identifying each category of funding within a budget account, sequestration reductions are
applied evenly across all budget account subcomponents referenced in committee reports, budget
justifications, and/or Presidential Detailed Budget Estimates – also known as programs, projects
or activities.6 For budget accounts that contain only one category of funding, all sequestrable
funds are reduced by the same corresponding percentage. For accounts that contain multiple
categories of funding, the total amount of each category of sequestrable funds is reduced by its
corresponding percentage. The reduced budget resources are usually permanently cancelled.7
As currently used, a sequester applies to either discretionary or mandatory spending.
Discretionary spending is associated with most funds provided by annual appropriations acts.
While all discretionary spending is subject to the annual appropriations process, only a portion of
mandatory spending is provided in appropriations acts.8 Mandatory spending is generally
provided by permanent laws, such as the Social Security Act which made indefinite budget
authority permanently available for Medicare benefit payments.9 Some federal programs, such as
Medicare, can receive both discretionary and mandatory funding.
In the event that a sequester is triggered, the Office of Management and Budget (OMB) is
responsible for calculating the across-the-board percentage reductions, and calculates separate
percentages for Medicare, other nondefense, and defense funding.10 Due to sequestration rules,
which are covered later in this report, mandatory Medicare benefit payments receive a specific
percentage reduction different from other types of federal spending.
The methodologies used to calculate these percentages and the sequestered amounts are published
in a report produced by OMB. Once the President issues a sequestration order, the associated
report is made available to the public and transmitted to Congress.11

Report 98-721, Introduction to the Federal Budget Process.
7 “In some circumstances current law allows for budget authority sequestered in one fiscal year to become available to
the agencies again in a subsequent fiscal year. OMB refers to these amounts as ‘pop ups.’” See U.S. Government
Accountability Office (GAO), 2014 Sequestration Opportunities Exist to Improve Transparency of Progress Toward
Deficit Reduction Goals, GAO-16-263, April 2016, p. 20, at https://www.gao.gov/assets/680/676565.pdf.
8 Some mandatory entitlements are provided through the annual appropriations process and are considered
appropriated entitlements (e.g., Medicaid). Although these entitlements are appropriated, the federal government is
legally obligated to make payments to those deemed eligible for the entitlement. (Medicaid is explicitly exempt from
sequestration.)
9 Indefinite budget authority is federal spending that, at the time of enactment, is for an unspecified amount that will be
determined at a later date. See GAO, A Glossary of Terms Used in the Federal Budget Process, GAO-05-734SP,
September 1, 2005, p. 23, at https://www.gao.gov/assets/80/76911.pdf.
10 All funds are first classified as discretionary or mandatory. Within each of these categories, funds are further
classified as Medicare, defense, or nondefense. During a sequestration order, each subcomponent of discretionary
and/or mandatory funds receives a sequestration percentage based on the necessary amount of savings for that category.
For sequestration purposes, Medicare benefit payments are defined by BBEDCA as all payments for programs and
activities under Title XVIII of the Social Security Act. See BBEDCA §256(d). Defense and nondefense are referred to
in BBEDCA as either “revised security” or “revised nonsecurity,” respectively. “Revised security” is any funding
coded with a budget function of 050, which is effectively the Department of Defense. “Revised nonsecurity” includes
all other government spending. Each of these categories receives a different percentage reduction under a sequestration
order.

Budget Enforcement Rules
Currently, there are three budget enforcement rules that can trigger sequestration. Two were
established by the BCA and one was established by Statutory PAYGO. The three rules and their
corresponding sequesters can be summarized as follows (and are presented in Table 1):
Budget Control Act
The BCA established a bipartisan Joint Select Committee on Deficit Reduction (Joint
Committee), which was responsible for developing legislation that would reduce the deficit by at
least $1.2 trillion from FY2012 to FY2021.12 However, the Joint Committee was unable to
achieve this goal; therefore, Congress and the President were unable to enact corresponding
deficit reduction legislation by a date specified in the law. As a result, two types of spending
reductions were automatically triggered.13
One automatic spending reduction involved the sequestration of certain mandatory spending from
FY2013 to FY2021. Subsequent legislation including, most recently, the Coronavirus Aid, Relief,
and Economic Security Act (CARES Act; P.L. 116-136) extended sequestration for mandatory
spending through FY2030.14 This reduction is referred to in this report as the “BCA mandatory
sequester.”
Additionally, the BCA established statutory limits on discretionary spending for FY2012-
FY2021.15 These discretionary spending limits (discretionary caps) restrict the amount of
spending permitted through the annual appropriations process for defense and nondefense
programs. Any breach of these discretionary caps results in the sequestration of nonexempt
discretionary funding. (This reduction is referred to in this report as the “BCA discretionary
sequester.”) This was triggered once in FY2013,16 and can be triggered again if discretionary caps
are breached in any fiscal year through FY2021 and Congress does not take action to raise these
caps. Most recently, the Bipartisan Budget Act of 2018 (BBA 2018; P.L. 115-123) increased the
discretionary spending caps for FY2018 and FY2019 so they would not be breached, and the

12 See Title IV of the BCA.
13 See CRS Report R42050, Budget “Sequestration” and Selected Program Exemptions and Special Rules.
14 Six subsequent pieces of legislation have extended the BCA mandatory sequester. The Bipartisan Budget Act of
2013 (BBA 2013; P.L. 113-67) extended the sequester through FY2023. A law modifying the cost-of-living adjustment
(COLA) for certain military retirees (P.L. 113-82) extended the sequester through FY2024. The Bipartisan Budget Act
of 2015 (BBA 2015; P.L. 114-74) extended the sequester through FY2025. The Bipartisan Budget Act of 2018 (BBA
2018; P.L. 115-123) extended the sequester through FY2027, and the Bipartisan Budget Act of 2019 (BBA 2019; P.L.
116-37) extended the sequester through FY2029. The Coronavirus Aid, Relief, and Economic Security Act (CARES
Act; P.L. 116-136) extended the sequester through FY2030. The CARES Act, as amended by the Consolidated
Appropriations Act, 2021 (P.L. 116-260), also temporarily suspended the application of sequestration to Medicare from
May 1, 2020, through March 31, 2021.
15 Four subsequent pieces of legislation have modified the BCA discretionary caps as enacted. BBA 2013 established
new discretionary caps under the BCA on defense and nondefense discretionary spending in FY2014 and FY2015.
BBA 2015 raised the discretionary caps in FY2016 and FY2017. BBA 2018 raised the discretionary caps in FY2018
and FY2019, and BBA 2019 raised the discretionary caps in FY2020 and FY2021. For more information about the
discretionary spending limits established under the BCA, see CRS Report R42506, The Budget Control Act of 2011 as
Amended: Budgetary Effects, and CRS Insight IN11148, The Bipartisan Budget Act of 2019: Changes to the BCA and

Bipartisan Budget Act of 2019 (BBA 2019; P.L. 116-37) increased the caps for FY2020 and
FY2021.
Statutory PAYGO
The Statutory PAYGO Act established a budget enforcement mechanism generally requiring that
legislation affecting direct (mandatory) spending and revenues does not have the effect of
increasing the deficit over a 5- and/or 10-year period. If such legislation were to become law, a
sequester of certain mandatory spending would be required. This budget enforcement rule does
not have a sunset date and therefore remains in effect under current law. (This reduction is
referred to in this report as Statutory PAYGO sequester.)
Although Congress has passed legislation that has been estimated to increase the deficit since the
law went into effect, the Statutory PAYGO sequester has never been triggered, as Congress has
voted to prohibit the effects of specific legislation from being counted under the normal
operations of the Statutory PAYGO Act. A recent example of this is BBA 2019,17 which included
language to reduce the “scorecards” tallying the total impact of legislation on the deficit to zero.

payments to contractors to process providers’ claims, beneficiary outreach and education, and maintenance of
Medicare’s information technology infrastructure. HCFAC refers to the Health Care Fraud and Abuse Control
Program, which is responsible for activities that fight health care fraud and waste and is funded through
discretionary and mandatory resources. Mandatory Administration includes, among other things, amounts
for quality improvement organizations. Medicare Benefit Payments are defined by BBEDCA as all payments
for programs and activities under Title XVIII of Social Security Act, including the Medicare Integrity Program.
MIP HCFAC refers to the Medicare Integrity Program, which focuses on combating fraud in Medicare. Non-
MIP HCFAC refers to all HCFAC spending other than MIP.
a. The Coronavirus Aid, Relief, and Economic Security Act (CARES Act; P.L. 116-136) specifies that the non-

the first six months of the FY2030 sequestration order and 0% for the last six months of the order. See
BBEDCA §251A(6)(C).

Sequester of Mandatory Spending through FY2029.
Medicare Overview
Medicare, which is a federal program that pays for certain health care services of qualified
beneficiaries, is subject to sequestration, although special rules limit the extent to which it is
impacted. Due to the varying payment structures of the four parts of the program, sequestration is
applied differently across Medicare.
Medicare was established in 1965 under Title XVIII of the Social Security Act to provide hospital
and supplementary medical insurance to Americans aged 65 and older. Over time, the program
has been expanded to also include certain disabled persons, including those with end-stage renal
disease. In FY2020, the program covered an estimated 63 million persons (54 million aged and 9
million disabled).18
The Congressional Budget Office (CBO) estimated that total Medicare spending in FY2020
would be about $836 billion and will increase to about $1.7 trillion in FY2030.19 Almost all
Medicare spending is mandatory spending that is primarily used to cover benefit payments (i.e.,
payments to health care providers for their services), administration, and the Medicare Integrity
Program (MIP). The remaining Medicare outlays are discretionary and used almost entirely for
other administrative activities that are described in more detail later in this report.

Medicare and Budget Sequestration

Medicare consists of four distinct parts:
1. Part A (Hospital Insurance, or HI) covers inpatient hospital services, skilled
nursing care, hospice care, and some home health services. Most persons aged 65
and older are automatically entitled to premium-free Part A because they or their
spouse paid Medicare payroll taxes for at least 40 quarters (about 10 years) on
earnings covered by either the Social Security or the Railroad Retirement
systems. Part A services are paid for out of the Hospital Insurance Trust Fund,
which is mainly funded by a dedicated 2.9% payroll tax on earnings of current
workers, shared equally between employers and workers.
2. Part B (Supplementary Medical Insurance, or SMI) covers a broad range of
medical services, including physician services, laboratory services, durable
medical equipment, and outpatient hospital services. Enrollment in Part B is
optional, but most beneficiaries with Part A also enroll in Part B. Part B benefits
are paid for out of the Supplementary Medical Insurance Trust Fund, which is
primarily funded through beneficiary premiums and federal general revenues.
3. Part C (Medicare Advantage, or MA) is a private plan option that covers all
Parts A and B services, except hospice. Individuals choosing to enroll in Part C
must be enrolled in Parts A and B. About one-third of Medicare beneficiaries are
enrolled in MA. Part C is funded through both the HI and SMI trust funds.
4. Part D is a private plan option that covers outpatient prescription drug benefits.
This portion of the program is optional. About three-quarters of Medicare
beneficiaries are enrolled in Medicare Part D or have coverage through an
employer retiree plan subsidized by Medicare. Part D benefits are also paid for
out of the Supplementary Medical Insurance Trust Fund and are primarily funded
through beneficiary premiums, federal general revenues, and state transfer
payments.
For more information on the Medicare program, see CRS Report R40425, Medicare Primer.
Beneficiary Costs
Beneficiaries are responsible for paying Medicare Parts B and D premiums, as well as other out-
of-pocket costs, such as deductibles and coinsurance,20 for services provided under all parts of the
Medicare program.21 Under Medicare Parts A, B and D, there is no limit on beneficiary out-of-
pocket spending, and most beneficiaries have some form of supplemental insurance through
private Medigap plans, employer-sponsored retiree plans, or Medicaid to help cover a portion of
their Medicare premiums and/or deductibles and coinsurance. Medicare Advantage has limits on
out-of-pocket spending.

20 A deductible is the amount an enrollee is required to pay for health care services or products before his or her
insurance plan begins to provide coverage. Coinsurance is the percentage share that an enrollee in a health insurance
plan pays for a product or service covered by the plan.
21 Beneficiaries enrolled in a Medicare Advantage (MA, Part C) plan must pay Part B premiums as well as any
additional premium required by the MA plan.

Medicare and Budget Sequestration

Provider and Plan Payments
Under Medicare Parts A and B, the government generally pays providers directly for services on a
fee-for-service basis using different prospective payment systems and fee schedules.22 Under
Parts C and D, Medicare pays private insurers a monthly capitated per person amount to provide
coverage to enrollees, regardless of the amount of services used. The capitated payments are
adjusted to reflect differences in the relative cost of sicker beneficiaries with different risk factors
including age, disability, or end-stage renal disease.
Health Care Fraud and Abuse Control Program
The Health Care Fraud and Abuse Control Program (HCFAC) was established by the Health
Insurance Portability and Accountability Act (HIPAA; P.L. 104-191) and is responsible for
activities that fight health care fraud and waste.23 HCFAC is funded using both mandatory and
discretionary funds and consists of three programs: (1) the HCFAC program, which finances the
investigative and enforcement activities undertaken by the Department of Health and Human
Services (HHS), the HHS Office of Office of Inspector General, the Department of Justice, and
the Federal Bureau of Investigation, (2) Medicaid Oversight, and (3) Medicare Integrity Program
(MIP).
Historically, MIP has focused on combating fee-for-service fraud in Medicare Parts A and B.
However, increases in private Medicare enrollment—Parts C and D—have expanded program
integrity efforts into capitated payment systems as well.
While HCFAC is not a part of the Medicare program, MIP is authorized by the same title of the
Social Security Act as Medicare and focuses entirely on the program. As a result, this portion of
HCFAC is treated as a part of Medicare benefit payments under a sequestration order and is
subject to the Medicare mandatory sequestration percentage limits.24
Administrative Spending
The administration of Medicare is funded through a combination of discretionary and mandatory
resources that are subject to reductions under a discretionary or mandatory sequestration order,
respectively. Discretionary administration funding includes amounts for payments to contractors
to process providers’ claims, beneficiary outreach and education, and maintenance of Medicare’s
information technology infrastructure. Mandatory administration funding includes amounts for
quality improvement organizations and Part B premium payments for Qualifying Individuals
(QI).25

22 Under a prospective payment system (PPS), Medicare payments are made using a predetermined, fixed amount based
on the classification system for a particular service. The Centers for Medicare & Medicaid Services (CMS) uses
separate PPSs to reimburse acute inpatient hospitals, home health agencies, hospice, hospital outpatient departments,
inpatient psychiatric facilities, inpatient rehabilitation facilities, long-term care hospitals, and skilled nursing facilities.
A fee schedule is a listing of fees used by Medicare to pay doctors or other providers/suppliers. Fee schedules are used
to pay for physician services; ambulance services; clinical laboratory services; and durable medical equipment,
prosthetics, orthotics, and supplies in certain locations.

Care Fraud and Abuse Control Program Report, at https://oig.hhs.gov/reports-and-publications/hcfac/index.asp.
24 For sequestration purposes, BBEDCA defines Medicare benefit payments as all payments for programs and activities
under Title XVIII of Social Security Act. This includes the Medicare Integrity Program (MIP). See BBEDCA §256(d).

Medicare Sequestration Rules
Special rules limit the total effect of budget sequestration on Medicare (see Table 1). Most
notably, BBEDCA, as amended by the BCA, prohibits Medicare benefit payments from being
reduced by more than 2% under a BCA mandatory sequestration order. Similarly, Statutory
PAYGO prohibits Medicare benefit payments from being reduced by more than 4% under a
Statutory PAYGO sequestration order.26 The caps do not apply to Medicare mandatory and
discretionary administrative spending, which is subject to the unrestricted percentage reduction
under both BCA and Statutory PAYGO sequestration orders.
Under the current mandatory sequestration order triggered by the BCA, the Medicare
sequestration percentage is capped at 2%.27 Therefore, as OMB determines the percentage
reductions for each budget category through FY2030, Medicare benefit payments cannot be
reduced by more than 2%; as such, another budget category may be subject to a higher percentage
reduction in order to achieve the necessary amount of savings.
More specifically, if OMB determines that total nonexempt, nondefense mandatory funds need to
be reduced by a percentage larger than 2% in order to achieve necessary savings under a BCA
sequestration order for a given year, then a 2% reduction would be made to Medicare benefit
spending, and the uniform reduction percentage for the remaining non-Medicare benefit,
nonexempt, nondefense mandatory programs would be recalculated and increased by an amount
to achieve the necessary level of reductions. If the uniform percentage reduction needed to
achieve the total amount of savings is less than 2%, then the determined percentage would be
applied to Medicare as well as to all other nonexempt non-Medicare nondefense mandatory
spending. Of note, if a mandatory sequestration order were triggered by Statutory PAYGO, the
process would be the same, but the reduction of payments for Medicare benefits would be capped
at 4%.28
In addition to these percentage caps, BBEDCA also prohibits Statutory PAYGO and BCA
mandatory sequestration effects from being included in the determination of annual adjustments
to Medicare payment rates established under Title XVIII of the Social Security Act.29 (See
“Reductions in Benefit Spending.”)
Finally, certain Medicare programs and activities are explicitly exempted from Statutory PAYGO
and BCA sequestration orders. Specifically, Part D low-income subsidies,30 Part D catastrophic

26 Medicare benefit payments are considered mandatory budgetary resources and would not be subject to a BCA
discretionary sequestration order.
27 See BBEDCA §251A(6). In addition, the CARES Act (P.L. 116-136) specifies that the non-administrative Medicare
sequester percentage cap will be 4% during the first six months of the FY2030 sequestration order (i.e., April through
September 2030) and 0% for the last six months of the order (i.e., October 2030 through March 2031), so the full
budgetary effects will occur within FY2030. See BBEDCA §251A(6)(C) and table note a in Table 1.

subsidies (reinsurance),31 and QI premiums cannot be reduced under a mandatory sequestration
order.32
Medicare Sequester Execution
Timing
Once a sequester is triggered, OMB issues a sequestration order for, at most, one fiscal year, and
subsequent orders are reissued for each fiscal year, as necessary. These orders can be issued either
before or during the fiscal year in which they apply, depending on the trigger.
Reductions in budget resources are to be made during the effective period of a sequestration
order; however special rules differentiate when a sequestration order is implemented for benefit
payments. As a result, sequestration orders are applied to Medicare benefit payments on a
different timeline than other mandatory and discretionary Medicare funds (i.e., Medicare
administration and HCFAC).
Once OMB issues a sequestration order, Medicare benefit payments are sequestered beginning on
the first date of the following month and remain in effect for all services furnished during the
following one-year period.33 In the event that a subsequent sequester order is issued prior to the
completion of the first order, the subsequent order begins on the first day after the initial order has
been completed. As an example, the first BCA mandatory sequester order (FY2013) was issued
on March 1, 2013, and took effect April 1, 2013. It remained in effect through March 31, 2014.
The FY2014 order was issued on April 10, 2013, (corrected on May 20, 2013) and was in effect
from April 1, 2014, to March 31, 2015.34
All other sequestrable funding is reduced only during the fiscal year associated with the sequester
report. Using the same example, the first BCA mandatory sequester order (FY2013) reduced
appropriate administrative spending from March 1, 2013, to September 30, 2013. The second
order for FY2014 sequestered funds from October 1, 2013, to September 30, 2014.
While OMB uses current law to determine the amount of funds available to be sequestered and
corresponding percentage reductions, actual Medicare outlays will not be known until after the
end of the fiscal year. Since sequestration orders are issued either before or during the fiscal year
in which they are applicable, OMB estimates the total sequestrable budget authority for Medicare,
and other accounts with indefinite budget authority, in order to determine necessary sequestration
percentages.35
If Medicare outlays exceed the estimated amount included in a sequestration order for that fiscal
year, the additional outlays are sequestered at the established percentage for that fiscal year. If

31 Part D pays nearly all drug costs above a catastrophic threshold, except for nominal beneficiary cost sharing.
Medicare subsidizes 80% of each plan’s costs for this catastrophic coverage. For more information on Medicare Part D,
see CRS Report R40611, Medicare Part D Prescription Drug Benefit.
32 See BBEDCA §256(d)(7).
33 See BBEDCA §256(d)(1).
34 Under current law, the sequestration of Medicare benefits under the BCA is effectively scheduled to continue
through September 30, 2030, due to special rules that cap the Medicare sequester percentage at 0% during the last six
months of the FY2030 order. Without this rule, Medicare benefit payments would be reduced for an additional six
months, through March 31, 2031 (i.e., reduced by 2% from April 1, 2030, through March 31, 2031, rather than 4%
from April through September 2030 and 0% from October 2030 through March 2031). See BBEDCA §251A(6)(C).

Medicare and Budget Sequestration

Medicare outlays are determined to be less than the estimated amount, no adjustments are made
to the sequestration order. In other words, OMB does not adjust sequestration percentages for any
category of budget authority once actuals are realized for accounts with indefinite budget
authority. Similarly, OMB does not adjust future orders to account for any previous discrepancies
between estimates and actuals.
Reductions in Benefit Spending
Parts A and B
Under Medicare Parts A and B, participating providers, such as hospitals and physicians, are paid
by the federal government on a fee-for-service basis for services provided to a beneficiary.
According to guidance issued by the Centers for Medicare & Medicaid Services (CMS), any
sequestration reductions are to be made to claims after determining coinsurance, deductibles, and
any applicable Medicare Secondary Payment adjustments.36 Therefore, sequestration applies only
to the portion of the payment paid to providers by Medicare; the beneficiary cost-sharing amounts
and amounts paid by other insurance are not reduced.
As an example, if the total allowed payment for a particular service is $100 and the beneficiary
has a 20% co-insurance, the beneficiary would be responsible for paying the provider the full $20
in co-insurance. The remaining 80% that is paid by Medicare would be reduced by 2% under the
FY2018 sequestration order, or $1.60 in this example, resulting in a total Medicare payment of
$78.40. In total, the provider would receive a payment of $98.40. This reduced payment is
considered payment in full and the Medicare beneficiary is not expected to pay higher
copayments to make up for the reduced Medicare payment.37
Part A inpatient services are considered to be furnished on the date of the individual’s discharge
from the inpatient facility. For services paid on a reasonable cost basis,38 the reduction is to be
applied to payments for such services incurred at any time during the sequestration period for the
portion of the cost reporting period that occurs during the effective period of the order. For Part B
services provided under assignment,39 the reduced payment is to be considered payment in full
and the Medicare beneficiary will not pay higher copayments to make up for the reduced
amount.40
Medicare non-participating providers, which are providers that do not elect to accept Medicare
payments on all claims in a given year, are not subject to the same rules. Medicare non-
participating providers receive a lower reimbursement rate from Medicare on all services

38 Most providers are paid under a prospective payment system or fee schedule. Some types of providers, such as
Critical Access Hospitals, are paid on a reasonable cost basis under which payments are based on actual costs incurred.
Reasonable cost is defined at Social Security Act §1861(v).
39 Assignment is an agreement by a doctor, provider, or supplier to be paid directly by Medicare, to accept the payment
amount Medicare approves for the service, and not to bill the beneficiary for any more than the Medicare deductible
and coinsurance (if applicable). Providers that don't accept assignment may charge more than the Medicare-approved
amount.

provided and may charge beneficiaries a limited amount more (balance bill charge) than the fee
schedule amount on non-assigned claims.41 In these instances, instead of the Medicare check
being sent to the provider, a check that incorporates the 2% reduction is mailed to the patient. The
patient must then pay the provider an amount that incorporates the sequestered amount. More
specifically, as payment, the beneficiary is responsible for paying the provider the amount listed
on the check, any cost sharing, balance bill charges, and the sequestered amounts taken out of the
provider check.42
Annual adjustments to Medicare payment rates are determined without incorporating
sequestration.43 However, the Medicare Payment Advisory Commission does incorporate the
effects of sequestration when assessing the adequacy of provider payments.44 The commission
uses these annual assessments to develop payment adjustment recommendations to the HHS
Secretary and/or Congress.
During the temporary suspension of sequestration of Medicare under the CARES Act, as
amended, fee-for-service provider payments will not be subject to the 2% reduction in Medicare
payments.45 The suspension is effective for claims with dates of service from May 1, 2020,
through March 31, 2021.
Part C (Medicare Advantage)
Under Medicare Advantage, private health plans are paid a per person monthly amount to provide
all Medicare-covered benefits, except hospice, to beneficiaries who enroll in their plan. These
capitated monthly payments are made to MA plans regardless of how many or how few services
beneficiaries actually use. The plan is at risk if costs for all of its enrollees exceed program
payments and beneficiary cost sharing; conversely, the plan can generally retain savings if
aggregate enrollee costs are less than program payments and cost sharing.
With respect to sequestration, reductions are uniformly made to the monthly capitated payments
to the private plans administering Medicare Advantage (Medicare Advantage Organizations or
MAOs). These fixed payments are determined every year with CMS approval through an annual
“bid process” and the amounts can vary depending on the private plan.46
In general, CMS payments to MAOs are generally comprised of amounts to cover medical costs,
administrative expenses, private plan profits, risk adjustments, and plan rebates to beneficiaries.47

Medicare and Budget Sequestration

MAOs have discretion to distribute any sequestration cut across these different components but
must still adhere to their legal obligations.48 Due to the temporary suspension of sequestration
from May 2020 through March of 2021, the 2% payment reduction that would have otherwise
applied to MAOs will not be applied during the suspension period. CMS has indicated that the
2% will also not apply to any future retroactive adjustments made to payments for beneficiaries
enrolled within the sequestration suspension period.49 (CMS will continue to apply sequestration
to payments for, and any retroactive adjustments made to payments for, beneficiaries enrolled
outside of the sequestration suspension period.)
Some MAOs have attempted to pass the reduction in their capitation rates onto providers through
lower reimbursement rates; however MAOs may be limited in their ability to do so.50 CMS
provided instructions regarding the treatment of contract and non-contract providers that provide
services under Part C. Specifically, “whether and how sequestration might affect an MAO’s
payments to its contracted providers are governed by the terms of the contract between the MAO
and the provider.”51 Therefore, in order for MAOs to reduce provider payments by the
sequestered amount, specific language within a contract must allow the reduction or the contract
would need to be renegotiated. Similarly, during the May 2020 through March 2021 CARES Act,
as amended, suspension of sequestration, the decision to suspend the application of the 2%
reduction to provider payments may depend on the reimbursement language in MAO-provider
contracts.52
In certain instances, such as when beneficiaries receive emergency out-of-network care, MAOs
need to reimburse the non-contracted providers; in such cases, the MAOs are required to pay at
least the rate providers would have received if the beneficiaries had been enrolled in original
Medicare. However, MAOs have the discretion of whether or not to incorporate sequestration
cuts into payments to non-contracted providers for those services.53 Non-contracted providers
must accept any payments reduced by the sequestration percentage as payment in full.

Medicare Part B or Part D premiums, or some combination of these options.

50 As a result of the initial BCA sequester, some Medicare Advantage Organizations (MAOs) attempted to reduce

providers. See Baptist Hosp. of Miami, Inc. v. Humana Health Ins. Co. of Florida, Inc. and Butler Healthcare Providers

Medicare and Budget Sequestration

In addition, regulations in the annual bid process restrict MAO’s potential responses to
sequestration. Specifically, MAOs are limited to “reasonable” revenue margins and a set
Medicare/non-Medicare profit margin discrepancy, among other requirements.54 Furthermore,
MAOs are restricted from allowing sequestration to impact a beneficiary’s plan benefits or
liabilities,55 so it becomes difficult for MAOs to pass an entire sequestration cut onto beneficiaries
through higher premiums or seek to offset lost revenue by increasing non-Medicare profits.
As HHS computes annual adjustments to Medicare payment rates, the Secretary cannot take into
account any reductions in payment amounts under sequestration for the Part C growth
percentage.56 In other words, plan payment updates are to be determined as if the reductions
under sequestration have not taken place. This results in larger annual adjustments compared to
baselines that incorporate sequestration cuts.
Part D
Under Medicare Part D, each plan receives a base capitated monthly payment, called a direct
subsidy, which is adjusted to incorporate three risk-sharing mechanisms (low-income subsidies,
individual reinsurance, and risk corridor payments). While each plan receives the same direct
subsidy amount for each enrollee regardless of how many benefits an enrollee actually uses, plans
receive different risk-sharing adjustments in their monthly payments. With respect to
sequestration, the 2% reductions are made only to the direct subsidy amounts. Part D risk-sharing
adjustments are exempt from sequestration and are therefore not reduced.57
During the May 2020 through March 2021 CARES Act, as amended, sequestration suspension
period, the 2% payment reductions to Part D plans will not occur. Payment adjustments during
the suspension period for Part D plans will be applied similarly to payments to MAOs under
Medicare Advantage.58 Also, similar to provider payments made by MAOs, whether and how
sequestration, and its temporary suspension, affects a Part D plan sponsor’s payment to its
contracted providers is “governed by the payment terms of the contract between the plan sponsor
and its network pharmacy providers.”59
Part D also contains a Retiree Drug Subsidy Program, which pays subsidies to qualified
employers and union groups that provide prescription drug insurance to Medicare-eligible, retired
workers. Instead of a capitated monthly payment, each sponsor receives a federal subsidy at the
end of the year to cover a portion of gross prescription drug costs for each retiree during that year.
Under this program, sequestration reductions are applied to the annual subsidy amount.60

Similar to Part C, the HHS Secretary is prohibited from taking into account any reductions in
payment amounts under sequestration for purposes of computing the Part D annual growth rate.61
Health Care Fraud and Abuse Control Program
As noted, the HCFAC program is not part of Medicare but does receive mandatory and
discretionary funds to ensure the programmatic integrity of the Medicare program. Under a BCA
sequestration order of mandatory funds, MIP funds are treated as a part of Medicare benefit
payments and are therefore subject to the Medicare 2% sequester limit. (The sequestration of this
portion of HCFAC funding has been suspended by the CARES Act, as amended, from May 2020
through March 2021.) HCFAC mandatory funding that does not exclusively address Medicare is
reduced by the nondefense mandatory sequester rate (5.7% in 2021), when applicable.
Administrative Expenses
Under either a mandatory or discretionary sequestration order, administrative spending within
nonexempt Medicare and HCFAC programs is reduced by the nondefense rate determined by
OMB. (Mandatory Medicare administrative spending authorized under Title XVIII of the Social
Security Act is exempt from sequester during the CARES Act, as amended, suspension period.)
Medicare and the BCA Mandatory Sequester
With the exception of the CARES Act, as amended, May 2020 through March 2021 suspension,
Medicare benefit payments have been subject to the 2% annual reduction limit established by the
BCA since the first BCA mandatory sequester order was issued in FY2013. Nondefense
mandatory budget authority reductions, which have applied to mandatory Medicare
administrative spending, have fluctuated between 5.1% and 7.3% from FY2013 through FY2021.

defined as Medicare or Defense Mandatory. MIP refers to the Medicare Integrity Program, which is under
HCFAC and focuses on combating fraud in Medicare.
In the FY2021 sequestration order, mandatory Medicare administrative expenses will be
sequestered by the nondefense mandatory percentage, 5.7% in FY2021. The total reduction in
Medicare administration budget authority, however, cannot be identified from the data presented
in the OMB sequestration report.62
In total, Medicare benefit payments (not including administration) are estimated to account for
90% of all Medicare and non-Medicare resources available to be sequestered (sequestrable
budget authority) under the FY2021 BCA mandatory sequester.63 Of the funds that are
sequestered, Medicare benefit payments are estimated to account for 74% of the combined
mandatory defense and nondefense sequestered funds.64
Traditionally, Medicare benefit payments comprise the largest single source of sequestered funds
in a given mandatory sequestration order. In FY2021, Medicare benefit payments are estimated to
account for the largest share of sequestrable budget authority and sequestered funds since the first
BCA sequestration order was issued for FY2013, as shown in Figure 1.65 (For FY2020, this
figure provides percentages based on the FY2020 sequestration order and does not reflect the
CARES Act, as amended, May 2020 through March 2021 suspension of sequestration. CBO
estimated the original CARES Act May 2020 through December 2020 suspension would increase
Medicare outlays by $4 billion in each of FY2020 and FY2021—for a total increase of $8 billion
but did not provide a separate estimate for the Consolidated Appropriations Act, 2021, extension
through March 2021.66)

62 CMS receives administrative funding for the Medicare program through the Medicare trust funds and the CMS
program management account. Since the OMB Report to the Congress on the Joint Committee Reductions for Fiscal
Year 2021 shows the amount of mandatory administrative funding sequestered at the account level, and CMS funds
other programs through the program management account, the total amount of mandatory administrative funding for
the Medicare program cannot be determined from the source.
63 For a list of sequestrable budget authority by budget account, see OMB Report to the Congress on the Joint
Committee Reductions for Fiscal Year 2021, February 10, 2020.
64 Ibid.
65 Since the mandatory BCA sequester went into effect, the total amount of Medicare benefit payments in a fiscal year
has generally increased at a faster rate than other mandatory spending in the corresponding fiscal year. If current trends
continue, Medicare benefit payments can be expected to continue to account for larger shares of total sequestered funds
through the end of the BCA mandatory sequester in FY2030. In Figure 1, Medicare benefit payments constituted a
higher percentage of all sequestered funds in FY2013 because the American Taxpayer Relief Act of 2012 (P.L. 112-
240) reduced the total amount of sequestered funds in FY2013 relative to all other fiscal years under the BCA
mandatory sequester.
66 Congressional Budget Office (CBO), Preliminary Estimate of the Effects of H.R. 748, the CARES Act, P.L. 116-136,
Revised, April 27, 2020, at https://www.cbo.gov/system/files/2020-04/hr748.pdf. Because the timing of the application
of the sequester to Medicare benefit payments is tied to the date of the initial sequestration order (i.e., from April 1 to
March 31), the actual sequestration reductions associated with a sequestration order straddle two different fiscal years.
CBO therefore projected that the Medicare sequestration suspension would increase direct spending in both FY2020
and FY2021. (The three-month Consolidated Appropriations Act, 2021 suspension extension also still falls within the
FY2020 order but occurs entirely in FY2021.) In addition to the temporary suspension, §3709 of the CARES Act also
amended the BCA (P.L. 112-25) to extend by one year (through FY2030) the sequestration of all nonexempt
mandatory spending. CBO scored the net impact of §3709 as decreasing direct spending (outlays) by $19 billion over
the 10-year, FY2020-FY2030, projection period. (In its score of Division N of the Consolidated Appropriations Act,
2021 (P.L. 116-260), CBO provided an aggregate estimate for all provisions in Title I and did not include a separate
estimate for the three-month Medicare sequestration suspension extension; see CBO, H.R. 133, Estimate for Division
N—Additional Coronavirus Response and Relief Consolidated Appropriations Act, 2021 P.L. 116-260, January 14,

Notes: Administrative funding is not included. Although Medicare Part C is sequestered, OMB sequestration
orders delineate at the trust fund level and do not distinguish each Medicare part. Part C is funded out of both
the Part A and Part B trust funds and is included in these totals.
CBO estimates that Medicare benefit payment outlays will more than double from FY2020 to
FY2030 (from $826 billion to $1,712 billion), the last year of BCA mandatory sequestration.68
Most of this expected increase is due to an aging population and rising health care costs per
person.69 Most of this increase would be subject to sequestration.
