Medicare (United States)

Not to be confused with Medicaid.

A sample Medicare card.
There are separate lines for basic Part A and Part B's supplementary medical coverage, each with its own date.
There are no lines for Part C or D, which are additional supplemental policies for which a separate card is issued.

In the United States, Medicare is a national social insurance program, administered by the U.S. federal government since 1966, currently using about 30 private insurance companies across the United States. Medicare provides health insurance for Americans aged 65 and older who have worked and paid into the system. It also provides health insurance to younger people with disabilities, end stage renal disease and amyotrophic lateral sclerosis.

In 2010, Medicare provided health insurance to 48 million Americans—40 million people age 65 and older and eight million younger people with disabilities. It was the primary payer for an estimated 15.3 million inpatient stays in 2011, representing 47.2 percent ($182.7 billion) of total aggregate inpatient hospital costs in the United States. Medicare serves a large population of elderly and disabled individuals. On average, Medicare covers about half (48 percent) of the health care charges for those enrolled. The enrollees must then cover the remaining approved charges either with supplemental insurance or with another form of out-of-pocket coverage. Out-of-pocket costs can vary depending on the amount of health care a Medicare enrollee needs. They might include uncovered services—such as long-term, dental, hearing, and vision care—and the supplemental insurance.

The Specialty Society Relative Value Scale Update Committee (or Relative Value Update Committee; RUC), composed of physicians associated with the American Medical Association, advises the government about pay standards for Medicare patient procedures, according to news reports.

Program history

President Johnson signing the Medicare amendment. Former President Harry S. Truman (seated) and his wife, Bess, are on the far right

In July 1965, under the leadership of President Lyndon Johnson, Congress created Medicare under Title XVIII of the Social Security Act to provide health insurance to people age 65 and older, regardless of income or medical history. Before Medicare's creation, approximately 65% of those over 65 had health insurance, with coverage often unavailable or unaffordable to the rest, because older adults paid more than three times as much for health insurance as younger people. In 1966, Medicare spurred the racial integration of thousands of waiting rooms, hospital floors, and physician practices by making payments to health care providers conditional on desegregation.

Medicare has been in operation for a half century and, during that time, has undergone several changes. Since 1965, the provisions of Medicare have expanded to include benefits for speech, physical, and chiropractic therapy in 1972 (Medicare.gov, 2012). Medicare added the option of payments to health maintenance organizations (Medicare.gov, 2012) in the 1980s. Over the years, Congress expanded Medicare eligibility to younger people who have permanent disabilities and receive Social Security Disability Insurance (SSDI) payments and those who have end-stage renal disease (ESRD). The association with HMOs begun in the 1980s was formalized under President Clinton in 1997. In 2003, under President George W. Bush, a Medicare program for covering almost all drugs was passed (and went into effect in 2006).

Since the creation of Medicare, science and medicine have advanced, and life expectancy has increased as well. The fact that people are living longer necessitates more services for later stages in life. Thus in 1982, the government added hospice benefits to aid the elderly on a temporary basis (Medicare.gov, 2012). Two years later in 1984, hospice became a permanent benefit. Congress further expanded Medicare in 2001 to cover younger people with amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease).

The Centers for Medicare and Medicaid Services (CMS), a component of the Department of Health and Human Services (HHS), administers Medicare, Medicaid, the Children's Health Insurance Program (CHIP), the Clinical Laboratory Improvement Amendments (CLIA) and parts of the Affordable Care Act (ACA). Along with the Departments of Labor and Treasury, CMS also implements the insurance reform provisions of the Health Insurance Portability and Accountability Act of 1996 (HIPAA) and most aspects of the Patient Protection and Affordable Care Act (PPACA) of 2010 as amended. The Social Security Administration is responsible for determining Medicare eligibility, eligibility for and payment of Extra Help/Low Income Subsidy payments related to Part D Medicare, and collecting some premium payments for the Medicare program.

The Chief Actuary of CMS is responsible for providing accounting information and cost-projections to the Medicare Board of Trustees to assist them in assessing the financial health of the program. The Board is required by law to issue annual reports on the financial status of the Medicare Trust Funds, and those reports are required to contain a statement of actuarial opinion by the Chief Actuary.

Since the beginning of the Medicare program, CMS has contracted with private insurance companies to operate as intermediaries between the government and medical providers. Contracted processes include claims and payment processing, call center services, clinician enrollment, and fraud investigation.

Financing

Medicare has several sources of financing.

Part A is largely funded by revenue from a 2.9% payroll tax levied on employers and workers (each pay 1.45%). Until December 31, 1993, the law provided a maximum amount of compensation on which the Medicare tax could be imposed each year, in the same way that the Social Security tax works in the United States. Beginning January 1, 1994, the compensation limit was removed. A self-employed individual must pay the entire 2.9% tax on self-employed net earnings (because they are both employee and employer), but may deduct half of the tax from the income in calculating income tax. Beginning in 2013, the rate of Part A tax on earned income exceeding US$200,000 for individuals (US$250,000 for married couples filing jointly) rose to 3.8%, in order to pay part of the cost of the subsidies mandated by the PPACA.

Parts B and D are partially funded by premiums paid by Medicare enrollees and general fund revenue. In 2006 a surtax was added to Part B premium for higher-income seniors to partially fund Part D. In the PPACA legislation of 2010, a surtax was added to the Part D premium for higher income seniors to partially fund PPACA and the number of Part B beneficiaries subject to the 2006 surtax was doubled, also partially to fund PPACA.

In 2011, Medicare spending accounted for about 15% of the Federal budget. This share is projected to exceed 17% by 2020.

The retirement of the Baby Boom generation—which by 2030 is projected to increase enrollment from 48 million to more than 80 million as the number of workers per enrollee declines from 3.7 to 2.4—and rising overall health care costs pose substantial financial challenges to the program. Medicare spending is projected to increase from $560 billion in 2010 to just over $1 trillion by 2022. Baby-boomers' health is also an important factor: 20% have five or more chronic conditions which will further add to the future cost of health care (www.cms.gov, 2012). In response, policymakers have recently offered a number of competing proposals to reduce Medicare costs.

Eligibility

In general, all persons 65 years of age or older who have been legal residents of the United States for at least 5 years are eligible for Medicare. People with disabilities under 65 may also be eligible if they receive Social Security Disability Insurance (SSDI) benefits. Specific medical conditions may also help people become eligible to enroll in Medicare.

People qualify for Medicare coverage, and Medicare Part A premiums are entirely waived, if the following circumstances apply:

• They are 65 years or older and U.S. citizens or have been permanent legal residents for 5 continuous years, and they or their spouse (or qualifying ex-spouse) has paid Medicare taxes for at least 10 years.

or

• They are under 65, disabled, and have been receiving either Social Security SSDI benefits or Railroad Retirement Board disability benefits; they must receive one of these benefits for at least 24 months from date of entitlement (eligibility for first disability payment) before becoming eligible to enroll in Medicare.

or

• They get continuing dialysis for end stage renal disease or need a kidney transplant.

or

• They are eligible for Social Security Disability Insurance and have amyotrophic lateral sclerosis (known as ALS or Lou Gehrig's disease).

Those who are 65 and older who choose to enroll in Part A Medicare must pay a monthly premium to remain enrolled in Medicare Part A if they or their spouse have not paid the qualifying Medicare payroll taxes.

People with disabilities who receive SSDI are eligible for Medicare while they continue to receive SSDI payments; they lose eligibility for Medicare based on disability if they stop receiving SSDI. The 24-month exclusion means that people who become disabled must wait 2 years before receiving government medical insurance, unless they have one of the listed diseases. The 24-month period is measured from the date that an individual is determined to be eligible for SSDI payments, not necessarily when the first payment is actually received. Many new SSDI recipients receive "back" disability pay, covering a period that usually begins 6 months from the start of disability and ending with the first monthly SSDI payment.

Some beneficiaries are dual-eligible. This means they qualify for both Medicare and Medicaid. In some states for those making below a certain income, Medicaid will pay the beneficiaries' Part B premium for them (most beneficiaries have worked long enough and have no Part A premium), as well as some of their out of pocket medical and hospital expenses.

Benefits

File:Medicare.gif

U.S. Medicare (2008)

Medicare has four parts: Part A is Hospital Insurance. Part B is Medical Insurance. Medicare Part D covers many prescription drugs, although some are covered by Part B. Part C health plans, the most popular of which are branded Medicare Advantage, are another way for Original Medicare beneficiaries to receive their Part A, B and D benefits (basically Part C is a public supplement option that can be compared with supplemental Medicare coverage from a former employer or private so-called Medigap insurance). All Medicare benefits are subject to medical necessity.

The original program included Parts A and B. Part-C-like plans have existed as demonstration projects in Medicare since the early 1980s but the Part was formalized by 1997 legislation. (Simplistically, Part C is a voucher program similar to the insurance reform included in the Patient Protection and Affordable Care Act of 2010 as amended). Part D was introduced January 1, 2006.

Part A: Hospital/Hospice insurance

Part A covers inpatient hospital stays, including semiprivate room, food, and tests.

The maximum length of stay that Medicare Part A will cover in a hospital inpatient stay or series of stays is typically 90 days. The first 60 days would be paid by Medicare in full, except one copay (also and more commonly referred to as a "deductible") at the beginning of the 60 days of $1,288 as of 2016. Days 61–90 require a co-payment of $322 per day as of 2016. The beneficiary is also allocated "lifetime reserve days" that can be used after 90 days. These lifetime reserve days require a copayment of $644 per day as of 2016, and the beneficiary can only use a total of 60 of these days throughout their lifetime.

A new pool of 90 hospital days, with new copays of $1288 in 2016 and $302 per day for days 61-90, starts only after the beneficiary has 60 days continuously with no payment from Medicare for hospital or nursing home.

Some services can be done as inpatient services, which would be reimbursed under Part A, or as outpatient services, which would not be reimbursed under Part A. The "Two-Midnight Rule" decides which is which. In August 2013, the Centers for Medicare and Medicaid Services announced a final rule concerning eligibility for hospital inpatient services effective October 1, 2013. Under the new rule, if a physician admits a Medicare beneficiary as an inpatient with an expectation that the patient will require hospital care that “crosses two midnights,” Medicare Part A payment is “generally appropriate.” However, if it is anticipated that the patient will require hospital care for less than two midnights, Medicare Part A payment is generally not appropriate. The time a patient spends in the hospital before an inpatient admission is formally ordered is considered outpatient time. But, hospitals and physicians can take into consideration the pre-inpatient admission time when determining if a patient’s care will reasonably be expected to cross two midnights to be covered under Part A.

Medicare penalizes hospitals for readmissions. After making initial payments for hospital stays, Medicare will take back from the hospital these payments, plus a penalty of 4 to 18 times the initial payment, if an above-average number of patients from the hospital are readmitted within 30 days. These readmission penalties apply after some of the most common treatments: pneumonia, heart failure, heart attack, COPD, knee replacement, hip replacement. A study conducted by the Agency for Healthcare Research and Quality (AHRQ) of 18 States found that 1.8 million Medicare patients aged 65 and older were readmitted within 30 days of an initial hospital stay in 2011; the conditions with the highest readmission rates were congestive heart failure, septicemia, pneumonia, and chronic obstructive pulmonary disease and bronchiectasis.

The highest penalties on hospitals are charged after knee or hip replacements, $265,000 per excess readmission. The goals are to encourage better post-hospital care and more referrals to hospice and end-of-life care in lieu of treatment, while the effect is also to reduce coverage in hospitals which treat poor and frail patients. The total penalties for above-average readmissions in 2013 are $280 million, for 7,000 excess readmissions, or $40,000 for each readmission above the US average rate.

Part A also covers brief stays for rehabilitation or convalescence in a skilled nursing facility if certain criteria are met:

1. A preceding hospital stay must be at least three days as an inpatient, three midnights, not counting the discharge date.
2. The nursing home stay must be for something diagnosed during the hospital stay or for the main cause of hospital stay.
3. If the patient is not receiving rehabilitation but has some other ailment that requires skilled nursing supervision then the nursing home stay would be covered.
4. The care being rendered by the nursing home must be skilled. Medicare part A does not pay stays which only provide custodial, non-skilled, or long-term care activities, including activities of daily living (ADL) such as personal hygiene, cooking, cleaning, etc.

The maximum length of stay that Medicare Part A will cover in a skilled nursing facility per ailment is 100 days. The first 20 days would be paid for in full by Medicare with the remaining 80 days requiring a co-payment of $161 per day as of 2016. Many insurance companies have a provision for skilled nursing care in the policies they sell.

If a beneficiary uses some portion of their Part A benefit and then goes at least 60 days without receiving facility-based skilled services, the 90-day hospital clock and 100-day nursing home clock are reset and the person qualifies for new benefit periods.

Hospice benefits are also provided under Part A of Medicare for terminally ill persons with less than six months to live, as determined by the patient's physician. The terminally ill person must sign a statement that hospice care has been chosen over other Medicare-covered benefits, (e.g. assisted living or hospital care). Treatment provided includes pharmaceutical products for symptom control and pain relief as well as other services not otherwise covered by Medicare such as grief counseling. Hospice is covered 100% with no co-pay or deductible by Medicare Part A except that patients are responsible for a copay for outpatient drugs and respite care, if needed.

As of 01/01/2015, the Medicare Part A has an inpatient hospital deductible of $1260, coinsurance per day as $315, coinsurance of life time reserve as $630, and coinsurance of Skilled Nursing Family as $157.50.

Part B: Medical insurance

Part B medical insurance helps pay for some services and products not covered by Part A, generally on an outpatient basis. Part B is optional and may be deferred if the beneficiary or his/her spouse is still working and has group health coverage through that employer. There is a lifetime penalty (10% per year) imposed for not enrolling in Part B unless actively working and receiving group health coverage from that employer.

Part B coverage begins once a patient meets his or her deductible ($147 in 2013), then typically Medicare covers 80% of approved services, while the remaining 20% is paid by the patient, either directly or indirectly by private Medigap insurance.

Part B coverage includes physician and nursing services, x-rays, laboratory and diagnostic tests, influenza and pneumonia vaccinations, blood transfusions, renal dialysis, outpatient hospital procedures, limited ambulance transportation, immunosuppressive drugs for organ transplant recipients, chemotherapy, hormonal treatments such as Lupron, and other outpatient medical treatments administered in a doctor's office. Medication administration is covered under Part B if it is administered by the physician during an office visit.

Part B also helps with durable medical equipment (DME), including canes, walkers, wheelchairs, and mobility scooters for those with mobility impairments. Prosthetic devices such as artificial limbs and breast prosthesis following mastectomy, as well as one pair of eyeglasses following cataract surgery, and oxygen for home use is also covered.

Complex rules are used to manage the benefit, and advisories are periodically issued which describe coverage criteria. On the national level these advisories are issued by CMS, and are known as National Coverage Determinations (NCD). Local Coverage Determinations (LCD) apply within the multi-state area managed by a specific regional Medicare Part B contractor, and Local Medical Review Policies (LMRP) were superseded by LCDs in 2003. Coverage information is also located in the CMS Internet-Only Manuals (IOM), the Code of Federal Regulations (CFR), the Social Security Act, and the Federal Register.

The deductible remains the same as $147 from 2014 to 2015. The Monthly Premium for Part B is $104.90, with income weighted contributions beginning for households earning more than $85,000 per person.

Part C: Medicare Advantage plans

Main article: Medicare Advantage

With the passage of the Balanced Budget Act of 1997, Medicare beneficiaries were formally given the option to receive their Original Medicare benefits through capitated health insurance Part C plans, instead of through the Original fee for service Medicare payment system. They had been previously doing so via a series of demonstration projects that dated back to the early 1980s. These Part C plans were initially known as "Medicare+Choice". As of the Medicare Modernization Act of 2003, most "Medicare+Choice" plans were rebranded as "Medicare Advantage" (MA) plans.

Original "fee-for-service" Medicare has a standard benefit package that covers medically necessary care that members can receive from nearly any hospital or doctor in the country (if that doctor or hospital accepts Medicare). Original Medicare beneficiaries who choose to enroll in a capitated Part C Medicare Advantage health plan instead give up none of their rights as an Original Medicare beneficiary, receive the same standard benefits—as a minimum—as provided in Original Medicare, and they get an annual out of pocket (OOP) limit not included in Original Medicare. However they must typically use only a select network of providers except in emergencies, typically restricted to the area surrounding their legal residence. Most Part C plans are traditional health maintenance organizations (HMOs) although a few are preferred provider organizations (which typically means the provider restrictions are not as confining as with an HMO). For almost all Part C plans, the beneficiary is required to have a primary care physician; that is not a requirement of Original Medicare.

The difference between using Original Medicare plus—for example—a private Medigap supplement versus sticking totally with Medicare through a public Part C Medicare Advantage health plan is the standard HMO vs. non-HMO decision faced by almost all U.S. residents that get their healthcare insurance through an employer. It has nothing directly to do with Medicare.

Public Part C Medicare Advantage health plan members typically also pay a monthly premium in addition to the Medicare Part B premium to cover items not covered by traditional Medicare (Parts A & B), such as the OOP limit, prescription drugs, dental care, vision care, annual physicals, coverage outside the United States, and even gym or health club memberships as well as—and probably most importantly—reduce the 20% co-pays and high deductibles associated with Original Medicare. But in some situations the benefits are more limited (but they can never be more limited than Original Medicare and must always include an OOP limit) and there is no premium. In some cases, the insurer even rebates part or all of the Part B premium although these types of Part C plans are becoming rare.

Public Part C Medicare Advantage and other Part C health plans are required to offer coverage that meets or exceeds the standards set by Original Medicare, but they do not have to cover every benefit in the same way. After approval by the Centers for Medicare and Medicaid Services, if a Part C plan chooses to pay less than Original Medicare for some benefits, such as Skilled Nursing Facility care, the savings may be passed along to consumers by offering even lower co-payments for doctor visits.

The 2003-law payment formulas purposely overcompensated Part C plans by 12 percent or more on average compared to what Original Medicare beneficiaries received in the same county on average, in order to increase the availability of Part C plans in rural and inner-city geographies. Before 2003 Part C plans tended to be suburban HMOs tied to major nearby teaching hospitals that cost the government the same as or even 5% less on average than it cost to cover the medical needs of a comparable beneficiary on Original Medicare. The 2003 law even began an incongruous capitated fee for service option within Part C.

Although the 2003 payment formulas succeeded in increasing the percentage of rural and inner city poor that could take advantage of the OOP limit and lower co-pays and deductibles—as well as the coordinated medical care—associated with Part C plans, in practice one set of Medicare beneficiaries received more benefits than others. These payment formulas were almost completely eliminated by PPACA and have been almost totally phased out according to the 2013 MedPAC annual report, March 2013.

Enrollment in public Part C health plans, including Medicare Advantage plans, grew from 5.4 million in 2005 to over 13 million in 2013. This represents 28% of Medicare beneficiaries. Almost all Medicare beneficiaries have access to at least two Medicare Advantage plans; most have access to three or more.

Part D: Prescription drug plans

Main articles: Medicare Part D and Medicare Part D coverage gap

Medicare Part D went into effect on January 1, 2006. Anyone with Part A or B is eligible for Part D. It was made possible by the passage of the Medicare Modernization Act. In order to receive this benefit, a person with Medicare must enroll in a stand-alone Prescription Drug Plan (PDP) or Medicare Advantage plan with prescription drug coverage (MA-PD). These plans are approved and regulated by the Medicare program, but are actually designed and administered by private health insurance companies and pharmacy benefit managers. Unlike Original Medicare (Part A and B), Part D coverage is not standardized (although it is highly regulated by the Centers for Medicare and Medicaid Services). Plans choose which drugs (or even classes of drugs) they wish to cover, at what level (or tier) they wish to cover it, and are free to choose not to cover some drugs at all. Plans that cover excluded drugs are not allowed to pass those costs on to Medicare, and plans are required to repay CMS if they are found to have billed Medicare in these cases.

Under the 2003 law that created Medicare Part D, the Social Security Administration provides extensive Extra Help to lower income seniors such that they have almost no drug costs. In addition approximately 25 states offer additional assistance on top of Part D. It should be noted again for beneficiaries who are dual-eligible (Medicare and Medicaid eligible) Medicaid may pay for drugs not covered by part D of Medicare.

Out-of-pocket costs

No part of Medicare pays for all of a beneficiary's covered medical costs and many costs are not covered at all. The program contains premiums, deductibles and coinsurance, which the covered individual must pay out-of-pocket. A study published by the Kaiser Family Foundation in 2008 found the Fee-for-Service Medicare benefit package was less generous than either the typical large employer Preferred provider organization plan or the Federal Employees Health Benefits Program Standard Option. Some people may qualify to have other governmental programs (such as Medicaid) pay premiums and some or all of the costs associated with Medicare.

Premiums

Most Medicare enrollees do not pay a monthly Part A premium, because they (or a spouse) have had 40 or more 3-month quarters in which they paid Federal Insurance Contributions Act taxes.The benefit is the same no matter how much or how little the beneficiary paid as long as the minimum number of quarters is reached. Medicare-eligible persons who do not have 40 or more quarters of Medicare-covered employment may buy into Part A for a monthly premium of:

• $248.00 per month (as of 2012) for those with 30–39 quarters of Medicare-covered employment, or
• $451.00 per month (as of 2012) for those with fewer than 30 quarters of Medicare-covered employment and who are not otherwise eligible for premium-free Part A coverage.

Most Medicare Part B enrollees pay an insurance premium for this coverage; the standard Part B premium for 2013 and 2014 is $104.90 -$335.70 per month. A new income-based premium surtax schema has been in effect since 2007, wherein Part B premiums are higher for beneficiaries with incomes exceeding $85,000 for individuals or $170,000 for married couples. Depending on the extent to which beneficiary earnings exceed the base income, these higher Part B premiums are $139.90, $199.80, $259.70, or $319.70 for 2012, with the highest premium paid by individuals earning more than $214,000, or married couples earning more than $428,000.

Medicare Part B premiums are commonly deducted automatically from beneficiaries' monthly Social Security checks. They can also be paid quarterly via bill sent directly to beneficiaries. This alternative is becoming more common because whereas the eligibility age for Medicare has remained at 65 as per the 1965 legislation the so-called Full Retirement Age for Social Security has been increased to 66 and will go even higher over time. Therefore, many people delay collecting Social Security and have to pay their Part B premium directly.

Part C and D plans may or may not charge premiums, depending on the plans' designs as approved by the Centers for Medicare and Medicaid Services.

Deductible and coinsurance

Part A — For each benefit period, a beneficiary will pay:

• A Part A deductible of $1,260 (in 2015) for a hospital stay of 1–60 days.
• A $315 per day co-pay (in 2015) for days 61–90 of a hospital stay.
• A $630 per day co-pay (in 2015) for days 91–150 of a hospital stay, as part of their limited Lifetime Reserve Days.
• All costs for each day beyond 150 days
• Coinsurance for a Skilled Nursing Facility is $157 per day (in 2015) for days 21 through 100 for each benefit period.
• A blood deductible of the first 3 pints of blood needed in a calendar year, unless replaced. There is a 3 pint blood deductible for both Part A and Part B, and these separate deductibles do not overlap.

Part B — After beneficiaries meet the yearly deductible of $166.00 (in 2016), they will be required to pay a co-insurance of 20% of the Medicare-approved amount for all services covered by Part B with the exception of most lab services which are covered at 100%, and outpatient mental health which is currently (2010–2011) covered at 55% (45% copay). The copay for outpatient mental health which started at 50% is gradually being stepped down over several years until it matches the 20% required for other services. They are also required to pay an excess charge of 15% for services rendered by physicians who do not accept assignment.

The deductibles, co-pays, and coinsurance charges for Part C and D plans vary from plan to plan. All Part C plans include an annual out of pocket limit. Original Medicare does not include an OOP limit.

Medicare supplement (Medigap) policies

Main article: Medigap

Of the Medicare beneficiaries that do not receive supplemental insurance via a former employer (40%) or a public Part C Medicare Advantage health plan (about 30%), almost all elect to purchase a type of private supplemental insurance coverage, called a Medigap plan, to help fill in the financial holes in Original Medicare (Part A and B). These Medigap insurance policies are standardized by CMS, but are sold and administered by private companies. Some Medigap policies sold before 2006 may include coverage for prescription drugs. Medigap policies sold after the introduction of Medicare Part D on January 1, 2006 are prohibited from covering drugs. Medicare regulations prohibit a Medicare beneficiary from having both a public Part C Medicare Advantage health plan and a Medigap Policy. Medigap policies may be purchased by beneficiaries who are receiving benefits from Original Medicare (Part A & Part B). They are regulated by state insurance departments rather than the federal government although CMS outlines what the various Medigap plans must cover at a minimum.

As of 2016 there are currently 11 policies being sold. These are Plan A, Plan B, Plan C, Plan D, Plan F, High Deductible Plan F, Plan G, Plan K, Plan L, Plan M, and Plan N. Cost is usually the only difference between Medigap policies with the same letter sold by different insurance companies. Unlike Medicare Advantage Plans, Medicare Supplement Plans have no networks, and any provider who accepts Medicare must also accept the Medicare Supplement Plan.

All insurance companies that sell Medigap policies are required to make Plan A available, and if they offer any other policies, they must also make either Plan C or Plan F available as well, although Plan F is scheduled to sunset in the year 2020. Anyone who currently has a Plan F will be allowed to keep in.

Payment for services

Medicare contracts with regional insurance companies to process over one billion fee-for-service claims per year. In 2008, Medicare accounted for 13% ($386 billion) of the federal budget. In 2010 it is projected to account for 12.5% ($452 billion) of the total expenditures. For the decade 2010–2019 medicare is projected to cost 6.4 trillion dollars or 14.8% of the federal budget for the period.

Reimbursement for Part A services

For institutional care, such as hospital and nursing home care, Medicare uses prospective payment systems. A prospective payment system is one in which the health care institution receives a set amount of money for each episode of care provided to a patient, regardless of the actual amount of care used. The actual allotment of funds is based on a list of diagnosis-related groups (DRG). The actual amount depends on the primary diagnosis that is actually made at the hospital. There are some issues surrounding Medicare's use of DRGs because if the patient uses less care, the hospital gets to keep the remainder. This, in theory, should balance the costs for the hospital. However, if the patient uses more care, then the hospital has to cover its own losses. This results in the issue of "upcoding," when a physician makes a more severe diagnosis to hedge against accidental costs.

Reimbursement for Part B services

Payment for physician services under Medicare has evolved since the program was created in 1965. Initially, Medicare compensated physicians based on the physician's charges, and allowed physicians to bill Medicare beneficiaries the amount in excess of Medicare's reimbursement. In 1975, annual increases in physician fees were limited by the Medicare Economic Index (MEI). The MEI was designed to measure changes in costs of physician's time and operating expenses, adjusted for changes in physician productivity. From 1984 to 1991, the yearly change in fees was determined by legislation. This was done because physician fees were rising faster than projected.

The Omnibus Budget Reconciliation Act of 1989 made several changes to physician payments under Medicare. Firstly, it introduced the Medicare Fee Schedule, which took effect in 1992. Secondly, it limited the amount Medicare non-providers could balance bill Medicare beneficiaries. Thirdly, it introduced the Medicare Volume Performance Standards (MVPS) as a way to control costs.

On January 1, 1992, Medicare introduced the Medicare Fee Schedule (MFS), a list of about 7,000 services that can be billed for. Each service is priced within the Resource-Based Relative Value Scale (RBRVS) with three Relative Value Units (RVUs) values largely determining the price. The three RVUs for a procedure are each geographically weighted and the weighted RVU value is multiplied by a global Conversion Factor (CF), yielding a price in dollars. The RVUs themselves are largely decided by a private group of 29 (mostly specialist) physicians—the American Medical Association's Specialty Society Relative Value Scale Update Committee (RUC).

From 1992 to 1997, adjustments to physician payments were adjusted using the MEI and the MVPS, which essentially tried to compensate for the increasing volume of services provided by physicians by decreasing their reimbursement per service.

In 1998, Congress replaced the VPS with the Sustainable Growth Rate (SGR). This was done because of highly variable payment rates under the MVPS. The SGR attempts to control spending by setting yearly and cumulative spending targets. If actual spending for a given year exceeds the spending target for that year, reimbursement rates are adjusted downward by decreasing the Conversion Factor (CF) for RBRVS RVUs.

Since 2002, actual Medicare Part B expenditures have exceeded projections.

In 2002, payment rates were cut by 4.8%. In 2003, payment rates were scheduled to be reduced by 4.4%. However, Congress boosted the cumulative SGR target in the Consolidated Appropriation Resolution of 2003 (P.L. 108-7), allowing payments for physician services to rise 1.6%. In 2004 and 2005, payment rates were again scheduled to be reduced. The Medicare Modernization Act (P.L. 108-173) increased payments 1.5% for those two years.

In 2006, the SGR mechanism was scheduled to decrease physician payments by 4.4%. (This number results from a 7% decrease in physician payments times a 2.8% inflation adjustment increase.) Congress overrode this decrease in the Deficit Reduction Act (P.L. 109-362), and held physician payments in 2006 at their 2005 levels. Similarly, another congressional act held 2007 payments at their 2006 levels, and HR 6331 held 2008 physician payments to their 2007 levels, and provided for a 1.1% increase in physician payments in 2009. Without further continuing congressional intervention, the SGR is expected to decrease physician payments from 25% to 35% over the next several years.

MFS has been criticized for not paying doctors enough because of the low conversion factor. By adjustments to the MFS conversion factor, it is possible to make global adjustments in payments to all doctors.

The SGR was the subject of possible reform legislation again in 2014. On March 14, 2014, the United States House of Representatives passed the SGR Repeal and Medicare Provider Payment Modernization Act of 2014 (H.R. 4015; 113th Congress), a bill that would have replaced the (SGR) formula with new systems for establishing those payment rates. However, the bill would pay for these changes by delaying the Affordable Care Act's individual mandate requirement, a proposal that was very unpopular with Democrats. The SGR was expected to cause Medicare reimbursement cuts of 24 percent on April 1, 2014, if a solution to reform or delay the SGR was not found. This led to another bill, the Protecting Access to Medicare Act of 2014 (H.R. 4302; 113th Congress), which would delay those cuts until March 2015. This bill was also controversial. The American Medical Association and other medical groups opposed it, asking Congress to provide a permanent solution instead of just another delay.

Provider Participation

There are three ways for providers to participate in Medicare. “Participating” providers take "assignment," which means that they accept Medicare’s approved rate for their services as payment in full. Some doctors do not take assignment or “participate”, but they also treat Medicare enrollees and are authorized to charge no more than a small fixed amount above Medicare’s approved rate. A minority of doctors are "private contractors," which means they opt out of Medicare and refuse to accept Medicare payments altogether. These doctors are required to inform patients will be liable for the full cost of their services out-of-pocket in advance of treatment.

While the majority of providers accept Medicare assignments, (97 percent for some specialties), and most physicians still accept at least some new Medicare patients, that number is in decline. While 80% of physicians in the Texas Medical Association accepted new Medicare patients in 2000, only 60% were doing so by 2012. A study published in 2012 concluded that the Centers for Medicare and Medicaid Services (CMS) relies on the recommendations of an American Medical Association advisory panel. The study led by Dr. Miriam J. Laugesen, of Columbia Mailman School of Public Health, and colleagues at UCLA and the University of Illinois, shows that for services provided between 1994 and 2010, CMS agreed with 87.4% of the recommendations of the committee, known as RUC or the Relative Value Update Committee.

Office medication reimbursement

Chemotherapy and other medications dispensed in a physician's office are reimbursed according to the Average Sales Price, a number computed by taking the total dollar sales of a drug as the numerator and the number of units sold nationwide as the denominator. The current reimbursement formula is known as "ASP+6" since it reimburses physicians at 106% of the ASP of drugs. Pharmaceutical company discounts and rebates are included in the calculation of ASP, and tend to reduce it. In addition, Medicare pays 80% of ASP+6 which is the equivalent of 84.8% of the actual average cost of the drug. Some patients have supplemental insurance or can afford the co-pay. Large numbers do not. This leaves the payment to physicians for most of the drugs in an "underwater" state. ASP+6 superseded Average Wholesale Price in 2005, after a 2003 front-page New York Times article drew attention to the inaccuracies of Average Wholesale Price calculations.

Medicare 10% incentive payments

"Physicians in geographic Health Professional Shortage Areas (HPSAs) and Physician Scarcity Areas (PSAs) can receive incentive payments from Medicare. Payments are made on a quarterly basis, rather than claim-by-claim, and are handled by each area's Medicare carrier."

Generally, if you are already receiving Social Security payments, at age 65 you will be automatically enrolled in Medicare Part A (Hospital Insurance). In addition, you will generally also be automatically enrolled in Medicare Part B (Medical Insurance). If you choose to accept Part B you will need to pay a monthly premium to keep it. However, you may delay enrollment with no penalty under some circumstances, or with penalty under other circumstances.

Part A & B

Part A Late Enrollment Penalty If you are not eligible for premium-free Part A, and you don’t buy a premium-based Part A when you’re first eligible, your monthly premium may go up 10%. You will have to pay the higher premium for twice the number of years you could have had Part A, but didn’t sign-up. For example, if you were eligible for Part A for 2 years but didn’t sign-up, you will have to pay the higher premium for 4 years. Usually, you don’t have to pay a penalty if you meet certain conditions that allow you to sign up for Part A during a Special Enrollment Period.

Part B Late Enrollment Penalty If you don’t sign up for Part B when you’re first eligible, you may have to pay a late enrollment penalty for as long as you have Medicare. Your monthly premium for Part B may go up 10% for each full 12-month period that you could have had Part B, but didn’t sign up for it. Usually, you don’t pay a late enrollment penalty if you meet certain conditions that allow you to sign up for Part B during a special enrollment period.

Comparison with private insurance

Medicare differs from private insurance available to working Americans in that it is a social insurance program. Social insurance programs provide statutorily guaranteed benefits to the entire population (under certain circumstances, such as old age or unemployment), benefits which are financed in significant part through universal taxes. In effect, Medicare is a mechanism by which the state takes a portion of its citizens' resources to guarantee health and financial security to its citizens in old age or in case of disability, helping them cope with the enormous, unpredictable cost of health care. In its universality, Medicare differs substantially from private insurers, which must make decisions about whom to cover and what benefits to offer in order to manage their risk pools and guarantee that costs do not exceed premiums.

Because the federal government is legally obligated to provide Medicare benefits to older and disabled Americans, it cannot cut costs by restricting eligibility or benefits, except by going through a difficult legislative process, or by revising its interpretation of medical necessity. By statute, Medicare may only pay for items and services that are "reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member", unless there is another statutory authorization for payment. Although cutting costs by cutting benefits is difficult, the program can also achieve substantial economies of scale in terms of the prices it pays for health care and administrative expenses and, as a result, private insurers’ costs have grown almost 60% more than Medicare’s since 1970.^{[Original research?]} Medicare’s cost growth is now the same as GDP growth and expected to stay well below private insurance’s for the next decade.

Because Medicare offers statutorily determined benefits, its coverage policies and payment rates are publicly known, and all enrollees are entitled to the same coverage. In the private insurance market, plans can be tailored to offer different benefits to different customers, enabling individuals to reduce coverage costs while assuming risks that they will not need care that is not covered. But insurers have far fewer disclosure requirements than Medicare, and studies show that customers in the private sector can face major difficulties determining what care is covered and at what cost. Moreover, since Medicare collects data about utilization and costs for its enrollees – data which private insurers treat as trade secrets – it provides researchers with key information about the performance of the health care system.

Medicare also has an important role driving changes in the entire health care system. Because Medicare pays for a huge share of health care in every region of the country, it has a great deal of power to set delivery and payment policies. For example, Medicare promoted the adaptation of prospective payments based on DRG’s, which prevents unscrupulous providers from setting their own exorbitant prices. Meanwhile, the Patient Protection and Affordable Care Act has given Medicare the mandate to promote cost-containment throughout the health care system, for example, by promoting the creation of accountable care organizations or by replacing fee-for-service payments with bundled payments.

Costs and funding challenges

Medicare and Medicaid Spending as % GDP (2013)

The Medicare Trustees reduced their forecast for Medicare costs as % GDP, mainly due to a lower rate of healthcare cost increases.

Over the long-term, Medicare faces significant financial challenges because of rising overall health care costs, increasing enrollment as the population ages, and a decreasing ratio of workers to enrollees. Total Medicare spending is projected to increase from $523 billion in 2010 to $932 billion by 2020. From 2010 to 2030, Medicare enrollment is projected to increase from 47 million to 79 million, and the ratio of workers to enrollees is expected to decrease from 3.7 to 2.4. However, the ratio of workers to retirees has declined steadily for decades, and social insurance systems have remained sustainable due to rising worker productivity. There is some evidence that productivity gains will continue to offset demographic trends in the near future.

The Congressional Budget Office (CBO) wrote in 2008 that "future growth in spending per beneficiary for Medicare and Medicaid—the federal government’s major health care programs—will be the most important determinant of long-term trends in federal spending. Changing those programs in ways that reduce the growth of costs—which will be difficult, in part because of the complexity of health policy choices—is ultimately the nation’s central long-term challenge in setting federal fiscal policy."

Overall health care costs were projected in 2011 to increase by 5.8 percent annually from 2010 to 2020, in part because of increased utilization of medical services, higher prices for services, and new technologies. Health care costs are rising across the board, but the cost of insurance has risen dramatically for families and employers as well as the federal government. In fact, since 1970 the per-capita cost of private coverage has grown roughly one percentage point faster each year than the per-capita cost of Medicare. Since the late 1990s, Medicare has performed especially well relative to private insurers. Over the next decade, Medicare’s per capita spending is projected to grow at a rate of 2.5 percent each year, compared to private insurance’s 4.8 percent. Nonetheless, most experts and policymakers agree containing health care costs is essential to the nation’s fiscal outlook. Much of the debate over the future of Medicare revolves around whether per capita costs should be reduced by limiting payments to providers or by shifting more costs to Medicare enrollees.

Indicators

Several measures serve as indicators of the long-term financial status of Medicare. These include total Medicare spending as a share of gross domestic product (GDP), the solvency of the Medicare HI trust fund, Medicare per-capita spending growth relative to inflation and per-capita GDP growth; and general fund revenue as a share of total Medicare spending.

Total Medicare spending as a share of GDP

This measure, which examines Medicare spending in the context of the U.S. economy as a whole, is expected to increase from 3.6 percent in 2010 to 5.6 percent in 2035 and to 6.2 percent by 2080.

The solvency of the Medicare HI trust fund

This measure involves only Part A. The trust fund is considered insolvent when available revenue plus any existing balances will not cover 100 percent of annual projected costs. According to the latest estimate by the Medicare trustees (2011), the trust fund is expected to become insolvent in 13 years (2024), at which time available revenue will cover 90 percent of annual projected costs. Since Medicare began, this solvency projection has ranged from two to 28 years, with an average of 11.3 years.

Medicare per-capita spending growth relative to inflation and per-capita GDP growth

The Independent Payment Advisory Board (IPAB), which the Affordable Care Act or "ACA" created, will use this measure to determine whether it must recommend to Congress proposals to reduce Medicare costs. Under the ACA, Congress established maximum targets, or thresholds, for per-capita Medicare spending growth. For the five-year periods ending in 2015 through 2019, these targets are based on the average of CPI-U and CPI-M. For the five-year periods ending in 2020 and subsequent years, these targets are based on per-capita GDP growth plus one percentage point. Each year, the CMS Office of the Actuary must compare those two values, and if the spending measure is larger than the economic measure, IPAB must propose cost-savings recommendations for consideration in Congress on an expedited basis. The Congressional Budget Office projects that Medicare per-capita spending growth will not exceed the economic target at any time between 2015 and 2021.

General fund revenue as a share of total Medicare spending

This measure, established under the Medicare Modernization Act (MMA), examines Medicare spending in the context of the federal budget. Each year, MMA requires the Medicare trustees to make a determination about whether general fund revenue is projected to exceed 45 percent of total program spending within a seven-year period. If the Medicare trustees make this determination in two consecutive years, a “funding warning” is issued. In response, the president must submit cost-saving legislation to Congress, which must consider this legislation on an expedited basis. In 2009, for the fourth consecutive year, the Medicare trustees determined that general fund revenue would exceed the threshold. However, in January 2009, the House passed a resolution to suspend congressional consideration of any legislation related to a Medicare funding warning.

Unfunded obligation

Medicare’s unfunded obligation is the total amount of money that would have to be set aside today such that the principal and interest would cover the gap between projected Part A revenues and spending over a given timeframe. As of 2009, Medicare’s unfunded obligation over an infinite timeframe was $36 trillion. Due to the passage of health reform, Medicare’s unfunded obligation over the next 75 years declined from $13.5 trillion to $3 trillion.

Public opinion

Popular opinion surveys show that the public views Medicare’s problems as serious, but not as urgent as other concerns. In January 2006, the Pew Research Center found 62 percent of the public said addressing Medicare’s financial problems should be a high priority for the government, but that still put it behind other priorities. Surveys suggest that there’s no public consensus behind any specific strategy to keep the program solvent.

Fraud and waste

Main article: Medicare fraud

The Government Accountability Office lists Medicare as a "high-risk" government program in need of reform, in part because of its vulnerability to fraud and partly because of its long-term financial problems. Fewer than 5% of Medicare claims are audited.

Criticism

Unearned entitlement or contribution-based insurance paid over a lifetime?

Yaron Brook of the Ayn Rand Institute has argued that the birth of Medicare represented a shift away from personal responsibility and towards a view that health care is an unearned "entitlement" to be provided at others' expense.

Robert M. Ball, a former commissioner of Social Security under President Kennedy in 1961 (and later under Johnson, and Nixon) defined the major obstacle to financing health insurance for the elderly: the high cost of care for the aged combined with the generally low incomes of retired people. Because retired older people use much more medical care than younger employed people, an insurance premium related to the risk for older people needed to be high, but if the high premium had to be paid after retirement, when incomes are low, it was an almost impossible burden for the average person. The only feasible approach, he said, was to finance health insurance in the same way as cash benefits for retirement, by contributions paid while at work, when the payments are least burdensome, with the protection furnished in retirement without further payment. In the early 1960s relatively few of the elderly had health insurance, and what they had was usually inadequate. Insurers such as Blue Cross, which had originally applied the principle of community rating, faced competition from other commercial insurers that did not community rate, and so were forced to raise their rates for the elderly.

Also, Medicare is not generally an unearned entitlement. Entitlement is most commonly based on a record of contributions to the Medicare fund. As such it is a form of social insurance making it feasible for people to pay for insurance for sickness in old age when they are young and able to work and be assured of getting back benefits when they are older and no longer working. Some people will pay in more than they receive back and others will get back more than they paid in, but this is the practice with any form of insurance, public or private.

Quality of beneficiary services

A 2001 study by the Government Accountability Office evaluated the quality of responses given by Medicare contractor customer service representatives to provider (physician) questions. The evaluators assembled a list of questions, which they asked during a random sampling of calls to Medicare contractors. The rate of complete, accurate information provided by Medicare customer service representatives was 15%. Since then, steps have been taken to improve the quality of customer service given by Medicare contractors, specifically the 1-800-MEDICARE contractor. As a result, 1-800-MEDICARE customer service representatives (CSR) have seen an increase in training, quality assurance monitoring has significantly increased, and a customer satisfaction survey is offered to random callers.

Hospital accreditation

In most states the Joint Commission, a private, non-profit organization for accrediting hospitals, decides whether or not a hospital is able to participate in Medicare, as currently there are no competitor organizations recognized by CMS.

Other organizations can also accredit hospitals for Medicare. These include the Community Health Accreditation Program, the Accreditation Commission for Health Care, the Compliance Team and the Healthcare Quality Association on Accreditation.

Accreditation is voluntary and an organization may choose to be evaluated by their State Survey Agency or by CMS directly.

Graduate Medical Education

Medicare funds the vast majority of residency training in the US. This tax-based financing covers resident salaries and benefits through payments called Direct Medical Education payments. Medicare also uses taxes for Indirect Medical Education, a subsidy paid to teaching hospitals in exchange for training resident physicians. For the 2008 fiscal year these payments were $2.7 and $5.7 billion respectively. Overall funding levels have remained at the same level over the last ten years, so that the same number or fewer residents have been trained under this program. Meanwhile, the US population continues to grow older, which has led to greater demand for physicians. At the same time the cost of medical services continue rising rapidly and many geographic areas face physician shortages, both trends suggesting the supply of physicians remains too low.

Medicare finds itself in the odd position of having assumed control of graduate medical education, currently facing major budget constraints, and as a result, freezing funding for graduate medical education, as well as for physician reimbursement rates. This halt in funding in turn exacerbates the exact problem Medicare sought to solve in the first place: improving the availability of medical care. However, some healthcare administration experts believe that the shortage of physicians may be an opportunity for providers to reorganize their delivery systems to become less costly and more efficient. Physicians' assistants and Advanced Registered Nurse Practitioners may begin assuming more responsibilities that traditionally fell to doctors, but do not necessarily require the advanced training and skill of a physician.

Of the 38,377 medical school graduates who applied for The National Resident Matching Program in 2012, 73.1%, 22,934, of US Medical School Graduates were able to find PGY-1 matches. In contrast, only 42.4% of graduates from Foreign Medical Schools who applied were successful. 3,909, or 10.2%, withdrew altogether from the match process, with the remaining 8,421, or 16.2%, who were unsuccessful in obtaining a residency slot in the PGY-1 match, left to attempt to rematch at a later time. The NRMR acknowledges that those who did not match in the previous years, and who reapplied for the match, were not included in the figures.

Legislation and reform

• 1960 — PL 86-778 Social Security Amendments of 1960 (Kerr-Mills aid)
• 1965 — PL 89-97 Social Security Act of 1965, Establishing Medicare Benefits
• 1980 — Medicare Secondary Payer Act of 1980, prescription drugs coverage added
• 1988 — PL 100-360 Medicare Catastrophic Coverage Act of 1988
• 1989 — Medicare Catastrophic Coverage Repeal Act of 1989
• 1997 — PL 105-33 Balanced Budget Act of 1997
• 2003 — PL 108-173 Medicare Prescription Drug, Improvement, and Modernization Act
• 2010 — Patient Protection and Affordable Care Act and Health Care and Education Reconciliation Act of 2010

In 1977, the Health Care Financing Administration (HCFA) was established as a federal agency responsible for the administration of Medicare and Medicaid. This would be renamed to Centers for Medicare and Medicaid Services (CMS) in 2001. By 1983, the diagnosis-related group (DRG) replaced pay for service reimbursements to hospitals for Medicare patients.

President Bill Clinton attempted an overhaul of Medicare through his health care reform plan in 1993–1994 but was unable to get the legislation passed by Congress.

In 2003 Congress passed the Medicare Prescription Drug, Improvement, and Modernization Act, which President George W. Bush signed into law on December 8, 2003. Part of this legislation included filling gaps in prescription-drug coverage left by the Medicare Secondary Payer Act that was enacted in 1980. The 2003 bill strengthened the Workers' Compensation Medicare Set-Aside Program (WCMSA) that is monitored and administered by CMS.

On August 1, 2007, the U.S. House United States Congress voted to reduce payments to Medicare Advantage providers in order to pay for expanded coverage of children's health under the SCHIP program. As of 2008, Medicare Advantage plans cost, on average, 13 percent more per person insured than direct payment plans. Many health economists have concluded that payments to Medicare Advantage providers have been excessive. The Senate, after heavy lobbying from the insurance industry, declined to agree to the cuts in Medicare Advantage proposed by the House. President Bush subsequently vetoed the SCHIP extension.

Effects of the Patient Protection and Affordable Care Act

The Patient Protection and Affordable Care Act ("PPACA") of 2010 made a number of changes to the Medicare program. Several provisions of the law were designed to reduce the cost of Medicare. Congress reduced payments to privately managed Medicare Advantage plans to align more closely with rates paid for comparable care under traditional Medicare. Congress also slightly reduced annual increases in payments to physicians and to hospitals that serve a disproportionate share of low-income patients. Along with other minor adjustments, these changes reduced Medicare’s projected cost over the next decade by $455 billion.

Additionally, the PPACA created the Independent Payment Advisory Board (“IPAB”), which will be empowered to submit legislative proposals to reduce the cost of Medicare if the program’s per-capita spending grows faster than per-capita GDP plus one percent. While the IPAB would be barred from rationing care, raising revenue, changing benefits or eligibility, increasing cost sharing, or cutting payments to hospitals, its creation has been one of the more controversial aspects of health reform.

The PPACA also made some changes to Medicare enrollee’s’ benefits. By 2020, it will close the so-called “donut hole” between Part D plans’ coverage limits and the catastrophic cap on out-of-pocket spending, reducing a Part D enrollee’s’ exposure to the cost of prescription drugs by an average of $2,000 a year. Limits were also placed on out-of-pocket costs for in-network care for Medicare Advantage enrollees. Meanwhile, Medicare Part B and D premiums were restructured in ways that reduced costs for most people while raising contributions from the wealthiest people with Medicare. The law also expanded coverage of preventive services.

The PPACA instituted a number of measures to control Medicare fraud and abuse, such as longer oversight periods, provider screenings, stronger standards for certain providers, the creation of databases to share data between federal and state agencies, and stiffer penalties for violators. The law also created mechanisms, such as the Center for Medicare and Medicaid Innovation to fund experiments to identify new payment and delivery models that could conceivably be expanded to reduce the cost of health care while improving quality.

Proposals for reforming Medicare

As legislators continue to seek new ways to control the cost of Medicare, a number of new proposals to reform Medicare have been introduced in recent years.

Premium support

Since the mid-1990s, there have been a number of proposals to change Medicare from a publicly run social insurance program with a defined benefit, for which there is no limit to the government’s expenses, into a program that offers "premium support" for enrollees. The basic concept behind the proposals is that the government would make a defined contribution, that is a premium support, to the health plan of a Medicare enrollee's choice. Insurers would compete to provide Medicare benefits and this competition would set the level of fixed contribution. Additionally, enrollees would be able to purchase greater coverage by paying more in addition to the fixed government contribution. Conversely, enrollees could choose lower cost coverage and keep the difference between their coverage costs and the fixed government contribution. The goal of premium Medicare plans is for greater cost-effectiveness; if such a proposal worked as planned, the financial incentive would be greatest for Medicare plans that offer the best care at the lowest cost.

There have been a number of criticisms of the premium support model. Some have raised concern about risk selection, where insurers find ways to avoid covering people expected to have high health care costs. Premium support proposals, such as the 2011 plan proposed by Rep. Paul Ryan (R–Wis.), have aimed to avoid risk selection by including protection language mandating that plans participating in such coverage must provide insurance to all beneficiaries and are not able to avoid covering higher risk beneficiaries. Some critics are concerned that the Medicare population, which has particularly high rates of cognitive impairment and dementia, would have a hard time choosing between competing health plans. Robert Moffit, a senior fellow of The Heritage Foundation responded to this concern, stating that while there may be research indicating that individuals have difficulty making the correct choice of health care plan, there is no evidence to show that government officials can make better choices. Henry Aaron, one of the original proponents of premium supports, has recently argued that the idea should not be implemented, given that Medicare Advantage plans have not successfully contained costs more effectively than traditional Medicare and because the political climate is hostile to the kinds of regulations that would be needed to make the idea workable.

Two distinct premium support systems have recently been proposed in Congress in order to control the cost of Medicare. The House Republicans’ 2012 budget would have abolished traditional Medicare and required the eligible population to purchase private insurance with a newly created premium support program. This plan would have cut the cost of Medicare by capping the value of the voucher and tying its growth to inflation, which is expected to be lower than rising health costs, saving roughly $155 billion over ten years. Paul Ryan, the plan’s author, claimed that competition would drive down costs, but the Congressional Budget Office (CBO) found that the plan would dramatically raise the cost of health care, with all of the additional costs falling on enrollees. The CBO found that under the plan, typical 65-year-olds would go from paying 35 percent of their health care costs to paying 68 percent by 2030.

In December 2011, Ryan and Sen. Ron Wyden (D–Oreg.) jointly proposed a new premium support system. Unlike Ryan’s original plan, this new system would maintain traditional Medicare as an option, and the premium support would not be tied to inflation. The spending targets in the Ryan-Wyden plan are the same as the targets included in the Affordable Care Act; it is unclear whether the plan would reduce Medicare expenditure relative to current law.

Raising the age of eligibility

A number of different plans have been introduced that would raise the age of Medicare eligibility. Some have argued that, as the population ages and the ratio of workers to retirees increases, programs for the elderly need to be reduced. Since the age at which Americans can retire with full Social Security benefits is rising to 67, it is argued that the age of eligibility for Medicare should rise with it (although people can begin receiving reduced Social Security benefits as early as age 62).

The CBO projected that raising the age of Medicare eligibility would save $113 billion over 10 years after accounting for the necessary expansion of Medicaid and state health insurance exchange subsidies under health care reform, which are needed to help those who could not afford insurance purchase it. The Kaiser Family Foundation found that raising the age of eligibility would save the federal government $5.7 billion a year, while raising costs for other payers. According to Kaiser, raising the age would cost $3.7 billion to 65- and 66-year-olds, $2.8 billion to other consumers whose premiums would rise as insurance pools absorbed more risk, $4.5 billion to employers offering insurance, and $0.7 billion to states expanding their Medicaid rolls. Ultimately Kaiser found that the plan would raise total social costs by more than twice the savings to the federal government.

Negotiating the prices of prescription drugs

Currently, people with Medicare can get prescription drug coverage through a Medicare Advantage plan or through the standalone private prescription drug plans (PDPs) established under Medicare Part D. Each plan established its own coverage policies and independently negotiates the prices it pays to drug manufacturers. But because each plan has a much smaller coverage pool than the entire Medicare program, many argue that this system of paying for prescription drugs undermines the government’s bargaining power and artificially raises the cost of drug coverage.

Many look to the Veterans Health Administration as a model of lower cost prescription drug coverage. Since the VHA provides healthcare directly, it maintains its owns formulary and negotiates prices with manufacturers. Studies show that the VHA pays dramatically less for drugs than the PDP plans Medicare Part D subsidizes. One analysis found that adopting a formulary similar to the VHA’s would save Medicare $14 billion a year (over 10 years the savings would be around $140 billion).

There are other proposals for savings on prescription drugs that do not require such fundamental changes to Medicare Part D’s payment and coverage policies. Manufacturers who supply drugs to Medicaid are required to offer a 15 percent rebate on the average manufacturer’s price. Low-income elderly individuals who qualify for both Medicare and Medicaid receive drug coverage through Medicare Part D, and no reimbursement is paid for the drugs the government purchases for them. Reinstating that rebate would yield savings of $112 billion, according to a recent CBO estimate.

Some have questioned the ability of the federal government to achieve greater savings than the largest PDPs, since some of the larger plans have coverage pools comparable to Medicare’s, although the evidence from the VHA is promising. Some also worry that controlling the prices of prescription drugs would reduce incentives for manufacturers to invest in R&D, although the same could be said of anything that would reduce costs.

Reforming care for the “dual-eligibles”

Roughly 9 million Americans – mostly older adults with low incomes – are eligible for both Medicare and Medicaid. These men and women tend to have particularly poor health – more than half are being treated for five or more chronic conditions – and high costs. Average annual per-capita spending for “dual-eligibles” is $20,000, compared to $10,900 for the Medicare population as a whole all enrollees.

The dual-eligible population comprises roughly 20 percent of Medicare’s enrollees but accounts for 36 percent of its costs. There is substantial evidence that these individuals receive highly inefficient care because responsibility for their care is split between the Medicare and Medicaid programs – most see a number of different providers without any kind of mechanism to coordinate their care, and they face high rates of potentially preventable hospitalizations. Because Medicaid and Medicare cover different aspects of health care, both have a financial incentive to shunt patients into care the other program will pay for.

Many experts have suggested that establishing mechanisms to coordinate care for the dual-eligibles could yield substantial savings in the Medicare program, mostly by reducing hospitalizations. Such programs would connect patients with primary care, create an individualized health plan, assist enrollees in receiving social and human services as well as medical care, reconcile medications prescribed by different doctors to ensure they do not undermine one another, and oversee behavior to improve health. The general ethos of these proposals is to “treat the patient, not the condition,” and maintain health while avoiding costly treatments.

There is some controversy over who exactly should take responsibility for coordinating the care of the dual eligibles. There have been some proposals to transfer dual eligibles into existing Medicaid managed care plans, which are controlled by individual states. But many states facing severe budget shortfalls might have some incentive to stint on necessary care or otherwise shift costs to enrollees and their families in order to capture some Medicaid savings. Medicare has more experience managing the care of older adults and will already be expanding coordinated care programs under the ACA, although there are some questions about private Medicare plans’ capacity to manage care and achieve meaningful cost savings.

Estimated savings from more effective coordinated care for the dual eligibles range from $125 billion to over $200 billion, mostly by eliminating unnecessary, expensive hospital admissions.

Income-relating Medicare premiums

Both House Republicans and President Obama proposed increasing the additional premiums paid by the wealthiest people with Medicare, compounding several reforms in the ACA that would increase the number of wealthier individuals paying higher, income-related Part B and Part D premiums. Such proposals are projected to save $20 billion over the course of a decade, and would ultimately result in more than a quarter of Medicare enrollees paying between 35 and 90 percent of their Part B costs by 2035, rather than the typical 25 percent. If the brackets mandated for 2035 were implemented today, it would mean that anyone earning more than $47,000 (as an individual) or $94,000 (as a couple) would be affected. Under the Republican proposals, affected individuals would pay 40 percent of the total Part B and Part D premiums, which would be equivalent of $2,500 today.

More limited income-relation of premiums only raises limited revenue. Currently, only 5 percent of Medicare enrollees pay an income-related premium, and most only pay 35 percent of their total premium, compared to the 25 percent most people pay. Only a negligible number of enrollees fall into the higher income brackets required to bear a more substantial share of their costs – roughly half a percent of individuals and less than three percent of married couples currently pay more than 35 percent of their total Part B costs.

There is some concern that tying premiums to income would weaken Medicare politically over the long run, since people tend to be more supportive of universal social programs than of means-tested ones.

Medigap restrictions

Some Medicare supplemental insurance (or “Medigap”) plans cover all of an enrollee's cost-sharing, insulating them from any out-of-pocket costs and guaranteeing financial security to individuals with significant health care needs. Many policymakers believe that such plans raise the cost of Medicare by creating a perverse incentive that leads patients to seek unnecessary, costly treatments. Many argue that unnecessary treatments are a major cause of rising costs and propose that people with Medicare should feel more of the cost of their care to create incentives to seek the most efficient alternatives. Various restrictions and surcharges on Medigap coverage have appeared in recent deficit reduction proposals. One of the furthest-reaching reforms proposed, which would prevent Medigap from covering any of the first $500 of coinsurance charges and limit it to covering 50 percent of all costs beyond that, could save $50 billion over ten years. But it would also increase health care costs substantially for people with costly health care needs.

There is some evidence that claims of Medigap’s tendency to cause over-treatment may be exaggerated and that potential savings from restricting it might be smaller than expected. Meanwhile, there are some concerns about the potential effects on enrollees. Individuals who face high charges with every episode of care have been shown to delay or forgo needed care, jeopardizing their health and possibly increasing their health care costs down the line. Given their lack of medical training, most patients tend to have difficulty distinguishing between necessary and unnecessary treatments. The problem could be exaggerated among the Medicare population, which has low levels of health literacy.[7]
