Medicaid Expansion Status by State

Under the Affordable Care Act, states were given the option to expand Medicaid eligibility. This map displays which states have adopted Medicaid expansion and which have not. Expansion decisions affect coverage access, state budgets, and provider networks, making this an important policy distinction across the United States.

This map reflects Medicaid expansion status as of June 2025. Some states may have partial expansions, waivers under negotiation, or pending legislative actions. Expansion status is based on official guidance from the Centers for Medicare & Medicaid Services (CMS) and state announcements.
