What is Medicaid?
Medicaid is a joint federal‑state program that pays for health care for low‑income people in the United States. Established in 1965 under Title XIX of the Social Security Act, Medicaid does not deliver care directly; instead it pays for covered services (doctor visits, hospital stays, long‑term care, prescription drugs, etc.) for eligible individuals. The program is funded by both the federal government and states and is run by each state, so eligibility rules, covered benefits, provider payments, and administration can vary significantly from state to state.

Key takeaways
– Medicaid covers tens of millions of low‑income Americans (about 70.6 million enrolled as of September 2020).
– Eligibility is income‑based and depends on family size, age, disability status, pregnancy, and state rules; many states expanded eligibility under the Affordable Care Act (ACA).
– The federal government matches state Medicaid spending (FMAP) at rates that vary by state (statutory minimum ~50% up to higher percentages for lower‑income states).
– Because states administer their own programs, benefits and rules vary—check your state Medicaid agency for specifics. (Sources: Medicaid.gov; CMS; Congressional Research Service; Kaiser Family Foundation)
Understanding Medicaid: who’s eligible and what’s covered
Eligibility groups commonly covered through Medicaid include:
– Low‑income children and pregnant women.
– Parents and other caretakers of dependent children (income thresholds vary).
– Older adults (65+) with low income and limited assets.
– People with disabilities, including those eligible for Supplemental Security Income (SSI).
– In expansion states, “new adult” group: adults under 65 without dependent children whose income falls at or below the expansion threshold (generally up to 138% of the federal poverty level, FPL) under the ACA. (Sources: MACPAC; CMS; KFF)
How income is measured
– Medicaid eligibility typically uses Modified Adjusted Gross Income (MAGI) rules for most adults, children, and pregnant women; MAGI is your federal taxable income adjusted for certain items (e.g., tax‑exempt interest, non‑taxable Social Security income may be excluded depending on the situation).
– States use FPL percentages (for example, 138% of FPL under ACA expansion) to set eligibility cutoffs for each group. Exact thresholds and categories vary by state. (Sources: CMS; MACPAC)
What Medicaid commonly covers
Coverage can vary by state, but Medicaid usually pays for:
– Primary and specialty doctor visits, hospital stays, emergency care.
– Preventive services, immunizations, lab tests.
– Prescription drugs (state lists vary).
– Long‑term services and supports (nursing home care, home‑and‑community‑based services) for eligible people.
– Behavioral health and substance‑use treatment in many states.
Some benefits are mandatory under federal law; others are optional and may differ by state. (Sources: CMS)
Medicaid funding and state administration
– Federal Medical Assistance Percentage (FMAP) determines the federal share of state Medicaid spending. FMAP varies by state based on per‑capita income; it ranges from a statutory minimum (~50%) up to higher rates for poorer states (e.g., up to ~83% in some cases).
– States design and manage their programs, decide benefit packages beyond federal minimums, set provider payment rates, and run eligibility and enrollment. Although federal rules apply, states have significant flexibility through waivers and state plan amendments. (Sources: Congressional Research Service; CMS)
Medicaid expansion under the ACA (Obamacare)
– The ACA (2010) allowed states to expand Medicaid to nearly all adults under 65 with incomes up to 138% of FPL. The Supreme Court (NFIB v. Sebelius, 2012) made expansion optional for states. As a result, some states expanded and others did not; that created different coverage options across the country. (Sources: CMS; U.S. Supreme Court decision)
Special conditions and populations
– Children: Many children qualify for Medicaid or the Children’s Health Insurance Program (CHIP) at higher FPL levels than adults. Children make up a large share of enrollees.
– Pregnant women: pregnancy generally raises the income threshold for coverage; prenatal care is a common covered benefit.
– Elderly and disabled: people who meet both income and asset tests (or who qualify via SSI) may get full Medicaid and often receive long‑term care coverage.
– People with disabilities may qualify for Medicaid even with very low or no income under special pathways (e.g., Medicaid buy‑in programs, waivers). (Sources: MACPAC; CMS)
Trump administration work requirements and legal status
– During the Trump administration, some states received federal approval to add “work and community engagement” requirements for certain Medicaid beneficiaries. Implementation in some states (e.g., Arkansas) led to coverage losses for people who didn’t meet documentary or activity requirements.
– Many such waivers and work‑requirement policies were challenged and blocked in federal courts; policy status has changed over time. Because the legal and administrative landscape evolves, check your state’s Medicaid website for current rules. (Sources: CMS; Commonwealth Fund; relevant court opinions)
Advantages of Medicaid
– Provides health coverage for people who otherwise could not afford private insurance.
– Covers a broad range of services, including long‑term care in many cases.
– Has been shown to reduce uninsurance, increase access to care, and improve some health outcomes among low‑income populations. (Sources: KFF; CMS; Commonwealth Fund)
Important limitations and considerations
– Coverage and benefits vary substantially by state.
– Provider participation may be limited in some areas because Medicaid reimbursement rates are often lower than private insurance. Always check whether a provider accepts Medicaid.
– Asset limits can apply for long‑term services in many states.
– Expansion status affects adult eligibility: in non‑expansion states, some low‑income adults may be ineligible for Medicaid but also not qualify for Marketplace subsidies. (Sources: KFF; CMS)
Practical steps — how to find out if you (or someone you help) qualify and how to apply
1. Check whether your state expanded Medicaid
– If you live in a state that expanded Medicaid, adults with income up to ~138% of FPL are often eligible. If your state did not expand, eligibility for adults may be much narrower. Use your state Medicaid website or a reliable tracker (e.g., Kaiser Family Foundation’s state expansion map) to confirm. (Source: KFF)
2. Estimate your income relative to the Federal Poverty Level (FPL)
– Find the current FPL amounts for your household size (CMS publishes FPL guidelines). Compare your household MAGI (federal taxable income with specific adjustments) to the FPL percentage thresholds used by your state to determine eligibility.
3. Gather documents you’ll likely need
– Proof of identity (driver’s license, state ID, birth certificate).
– Social Security numbers (or document numbers for immigrants).
– Proof of state residency (utility bill, lease).
– Proof of income (pay stubs, tax returns, benefit statements).
– Proof of pregnancy or disability, if applying under those categories. Requirements vary by state—check your state Medicaid agency’s checklist. (Source: Medicaid.gov)
4. Apply through the right channel
– In states that use the federal Health Insurance Marketplace, you can apply at HealthCare.gov and indicate you want to apply for Medicaid/CHIP. Many states allow direct applications through the state Medicaid agency website, local county office, or by mail/phone. Follow your state’s process. (Source: Medicaid.gov)
5. If approved, choose a plan or provider (if applicable)
– Many states use Medicaid managed‑care plans; you may be asked to pick a managed‑care plan. Review plan provider directories to confirm your doctors and local hospitals accept the plan. If you don’t pick a plan, the state may auto‑assign one. (Source: State Medicaid agency/CMS)
6. If denied, use the appeals process
– You have a right to appeal denials or to request a fair hearing. The denial notice will explain deadlines and how to file an appeal. Follow the steps carefully and meet deadlines; you can often get free legal help from local legal aid organizations or consumer assistance programs. (Source: Medicaid.gov)
7. Keep coverage active
– Report changes in income, household composition, or address as required. Pay attention to renewal notices—states will periodically redetermine eligibility. Missing documentation or renewal steps can cause coverage termination. (Source: Medicaid.gov)
8. If you don’t qualify for Medicaid
– Check CHIP for children, Marketplace plans with premium tax credits (if your income is above the Medicaid cutoff in a non‑expansion state), or state programs for limited services. Community health centers provide sliding‑scale care regardless of insurance for many services. (Sources: CMS; KFF)
Checklist to apply right now
– Find your state Medicaid website (search “[state] Medicaid” or use Medicaid.gov to locate state pages).
– Look up your state’s eligibility rules and required documents.
– If your state uses HealthCare.gov, create an account and start an application; indicate you want to apply for Medicaid/CHIP.
– Contact your state Medicaid office or local enrollment navigator if you need help—many community groups, hospitals, and legal aid groups provide free enrollment assistance. (Source: Medicaid.gov)
