Under the Affordable Care Act, states have the option of expanding Medicaid eligibility criteria to a broader group of people. By adopting Medicaid expansion, more children and families become eligible for Medicaid, and more children and families are covered by health insurance. Expanded eligibility for Medicaid coverage has been shown to improve children’s use of preventive care, reduce infant mortality, lower families’ out-of-pocket medical expenditures, and reduce the amount of their unpaid medical bills.
Medicaid expansion status for each state is based on the Kaiser Family Foundation’s tracking and analysis of state expansion activity. States’ decisions about adopting Medicaid expansion are as of September 20, 2022. States that have adopted but not yet implemented Medicaid expansion are included as being Medicaid expansion states.
