What is Medicaid?

Medicaid is a joint federal-state health insurance program in the United States that provides coverage for low-income individuals and families, including children, pregnant women, parents, seniors, and people with disabilities. It was established in 1965 alongside Medicare.

Medicaid is the largest source of health coverage in the United States for low-income populations, providing essential health services to millions of Americans.

How Medicaid Works

Funding

Medicaid is funded jointly by the federal government and individual states. The federal government provides a matching percentage of each state's Medicaid spending, with the match rate varying based on the state's per capita income. Poorer states receive a higher federal match.

Administration

Each state administers its own Medicaid program within federal guidelines, determining eligibility criteria and covered services. This means Medicaid looks different in every state, with varying benefits and eligibility rules.

Covered Services

Eligibility

Medicaid eligibility varies by state, but generally includes these groups:

• Children: Up to age 19 in households with income below certain thresholds
• Pregnant Women: Income-based eligibility, often with higher limits
• Parents/Caretakers: Low-income parents caring for children
• Seniors: Individuals aged 65+ with limited income and assets
• People with Disabilities: Individuals with permanent disabilities

Medicaid Expansion

The Affordable Care Act (ACA) authorized states to expand Medicaid eligibility to adults with incomes up to 138% of the federal poverty level. As of 2026, most states have adopted Medicaid expansion, providing coverage to millions of additional low-income adults who were previously ineligible.

Medicaid vs. Medicare

Medicaid is a joint federal-state program for low-income individuals of all ages, while Medicare is a federal program primarily for seniors aged 65+. Some individuals qualify for both programs (dual eligibility), with Medicaid covering costs not covered by Medicare.
