KFF Tracker Shows 40 States Have Adopted Medicaid Expansion

The Kaiser Family Foundation maintains an interactive map tracking Medicaid expansion status across all 50 states and DC under the Affordable Care Act. As of the latest update, 40 states and DC have adopted expansion, while 10 states have not expanded. The tracker provides current adoption status and links to additional expansion resources.
