Medicaid (United States) is a public health insurance program created in 1965 to provide medical assistance to low-income Health insurance populations under the Social Security Amendments of 1965. It operates through a partnership between the United States Department of Health and Human Services, state governments such as California and Texas, and local agencies including county health departments. The program interacts with other federal programs like Medicare (United States) and policy initiatives such as the Affordable Care Act and various state-level waivers.

History

Medicaid was established alongside Medicare (United States) by the Social Security Amendments of 1965, enacted during the administration of Lyndon B. Johnson and signed into law at the White House with advocates like Eleanor Roosevelt and legislators from the United States Congress. Early implementation involved coordination with state programs already run in states such as California and New York City's municipal systems. Major expansions occurred under presidents Bill Clinton with the State Children's Health Insurance Program and Barack Obama via the Affordable Care Act, which introduced an optional expansion of eligibility that several states including Massachusetts and Vermont adopted while others like Texas initially resisted. Key legal milestones include the Supreme Court decision in National Federation of Independent Business v. Sebelius affecting expansion and numerous Centers for Medicare & Medicaid Services rulings shaping coverage rules.

Eligibility and Enrollment

Eligibility criteria derive from federal statutes administered by the Centers for Medicare & Medicaid Services and vary by state such as Florida and Illinois. Mandatory categories include low-income families, pregnant women, children, and individuals receiving Supplemental Security Income, while optional eligibility can cover populations like adults without dependent children and individuals with disabilities such as recipients of Social Security Disability Insurance. Enrollment processes interact with state marketplaces created under the Affordable Care Act and agencies including state departments of health and human services in jurisdictions like Ohio and Pennsylvania. Outreach and enrollment have been influenced by programs run by organizations such as the Kaiser Family Foundation and legal advocacy groups like the American Civil Liberties Union.

Benefits and Coverage

Federal law requires states to cover certain mandatory services including inpatient and outpatient hospital services, physician services, and nursing facility services; optional benefits may include prescription drugs, dental services, and home- and community-based services administered through waivers like the Section 1115 waiver. Covered populations receive services through managed care organizations regulated by state insurance commissioners and federal agencies including the Centers for Medicare & Medicaid Services. Benefit design often coordinates with other entitlements such as Supplemental Nutrition Assistance Program supports and veterans' benefits administered by the Department of Veterans Affairs for dual-eligible beneficiaries.

Financing and Expenditures

Medicaid is jointly funded by federal and state governments with federal matching rates calculated through the Federal Medical Assistance Percentage formula overseen by the United States Department of Health and Human Services. Major expenditures include acute care, long-term services and supports, and prescription drug spending tracked by research groups such as the Urban Institute and the Kaiser Family Foundation. State budgets from places like New York (state) and California reflect Medicaid's share of spending, and fiscal pressures intersect with federal appropriations passed by the United States Congress and budget actions by the Office of Management and Budget.

Administration and Federal–State Relations

Administration involves federal sets of rules by the Centers for Medicare & Medicaid Services alongside state agencies such as the New York State Department of Health and the California Department of Health Care Services. States may apply for waivers—such as Section 1115 waivers—to pilot programs, negotiated with the federal government and sometimes involving governors' offices like those of New Jersey and Arizona. Tensions over eligibility, financing, and managed care contracts have occasioned litigation before courts including the Supreme Court of the United States and negotiations between state legislatures and governors.

Impact and Outcomes

Research by institutions like the National Bureau of Economic Research and the Urban Institute indicates Medicaid expansion under the Affordable Care Act reduced uninsured rates, improved access to care in states such as Kentucky and New Mexico, and affected measures including preventable hospitalizations and financial security monitored by scholars at Harvard University and Johns Hopkins University. Studies also examine impacts on maternal and child health outcomes, long-term care use, and public health responses coordinated with agencies like the Centers for Disease Control and Prevention during public health emergencies.

Criticisms and Reform Efforts

Criticisms come from policymakers across the spectrum including members of United States Congress and state executives, focusing on provider reimbursement rates, program complexity, and variations between states like Mississippi and Massachusetts. Reform proposals have ranged from block grants advocated by some governors and think tanks such as the Heritage Foundation to single-payer models promoted by activists affiliated with organizations like Democratic Socialists of America and academic proponents at Columbia University. Efforts to address long-term care funding, fraud control pursued by the Department of Justice, and innovation through value-based purchasing have animated debates about the program's future.
