To date, 39 states (including DC) have adopted the Medicaid expansion and 12 states have not adopted the expansion. Current status for each state is based on KFF tracking and analysis of state expansion activity.
This table tracks state actions related to adoption of the ACA Medicaid expansion. For non-expansion states, we include actions toward potential adoption. These include legislative actions (passage of bills in at least one legislative chamber or committee), executive actions (Governor’s budget proposal, executive orders, or other significant announcements), and voter-led actions (progress toward ballot initiatives). For expansion states, we include summaries of when and how late-adopting states took up the expansion as well as notes on state attempts to place limits or requirements on the expansion population, especially through Section 1115 waivers.
