Medicare (United States)

Medicare (United States). Medicare is a federal health insurance program in the United States, primarily for individuals aged 65 and older, but also for certain younger people with disabilities and those with End-Stage Renal Disease. Established under the Social Security Amendments of 1965 and signed into law by President Lyndon B. Johnson, it is administered by the Centers for Medicare & Medicaid Services within the Department of Health and Human Services. The program provides critical coverage for hospital care, medical services, and prescription drugs, playing a foundational role in the American healthcare system.

History and legislative background

The origins of Medicare trace back to early 20th-century advocacy for national health insurance, with efforts by figures like Harry S. Truman who proposed a universal system. The political momentum for a program for seniors grew through the work of the Committee on Economic Security and advocacy by groups like the American Medical Association and the AFL–CIO. A pivotal moment was the 1960 enactment of the Kerr–Mills Act, which provided federal grants to states for medical assistance to the elderly. The decisive legislative push came under the Johnson administration, with key architects including Representative Wilbur Mills and Senator Robert F. Wagner. The program was enacted as Title XVIII of the Social Security Act on July 30, 1965, at a ceremony in Independence, Missouri with former President Truman present. Major subsequent expansions include the Medicare Prescription Drug, Improvement, and Modernization Act of 2003, which added outpatient drug coverage, and the Affordable Care Act of 2010, which introduced measures to improve benefits and reform payment systems.

Program structure and parts

Medicare is divided into distinct parts that cover specific services. Medicare Part A covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care. Medicare Part B covers certain doctors' services, outpatient care, medical supplies, and preventive services. Medicare Part C, also known as Medicare Advantage, is an alternative offered by private companies like UnitedHealth Group and Humana that contract with Medicare to provide all Part A and Part B benefits, often including additional coverage. Medicare Part D adds prescription drug coverage through plans run by private insurers approved by Medicare, such as those offered by CVS Health and Cigna. Supplemental coverage is also available through private Medigap policies standardized by the National Association of Insurance Commissioners.

Eligibility and enrollment

Individuals are generally eligible for Medicare if they or their spouse worked for at least 10 years in Medicare-covered employment and are 65 years or older and a citizen or permanent resident of the United States. People under 65 can qualify if they have received Social Security Disability Insurance benefits for 24 months or have a diagnosis of Amyotrophic Lateral Sclerosis or End-Stage Renal Disease. Initial enrollment typically occurs during a seven-month period surrounding one's 65th birthday, with special enrollment periods for those covered under employer plans like those from General Motors or IBM. Enrollment is managed through the Social Security Administration, and beneficiaries can choose to receive their benefits through Original Medicare or a Medicare Advantage plan during the annual Annual Election Period.

Financing and costs

Medicare is funded through a combination of payroll taxes, premiums from beneficiaries, and general federal revenue. The Hospital Insurance Trust Fund, which finances Medicare Part A, is primarily funded by payroll taxes levied under the Federal Insurance Contributions Act. Medicare Part B and Medicare Part D are financed through monthly premiums paid by enrollees and contributions from the U.S. Treasury. Beneficiaries are responsible for cost-sharing, including deductibles, copayments, and coinsurance. The Medicare Board of Trustees, which includes the Secretary of the Treasury and the Secretary of Health and Human Services, annually reports on the program's financial status to Congress.

Administration and oversight

The Centers for Medicare & Medicaid Services, a federal agency within the Department of Health and Human Services headquartered in Woodlawn, Baltimore, administers Medicare. Day-to-day operations, including claims processing and customer service, are handled by private contractors known as Medicare Administrative Contractors, such as Noridian Healthcare Solutions and Palmetto GBA. Program integrity and combating fraud are overseen by the Department of Health and Human Services Office of Inspector General and the Federal Bureau of Investigation. The Medicare Payment Advisory Commission provides independent advice to the U.S. Congress on issues affecting the program.

Policy issues and reform debates

Key policy challenges for Medicare include ensuring the long-term solvency of the Hospital Insurance Trust Fund, managing rising healthcare costs driven by factors like pharmaceutical prices from companies like Pfizer and Merck & Co., and improving the quality of care. Major reform debates often center on proposals to alter the program's structure, such as transitioning to a premium support model advocated by some members of Congress and think tanks like the American Enterprise Institute. Other ongoing discussions involve expanding benefits to include dental and vision care, lowering the eligibility age, and allowing the program to negotiate drug prices directly, a provision included in the Inflation Reduction Act of 2022. These debates are heavily influenced by advocacy from organizations like the AARP and the Kaiser Family Foundation.
