Medicaid provides health insurance for millions of low-income, disabled and elderly Americans. While all 50 states participate in the federal program, eligibility requirements vary by state.

Thirty-one states have expanded Medicaid coverage to insure additional patients under the Patient Protection and Affordable Care Act (ACA). In states that have expanded coverage, Medicaid eligibility is available to individuals reporting incomes up to 138 percent of the federal poverty level, which varies depending on the size of a household. For a family of three, the 2017 federal poverty level was $20,420.
