Key States with 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). We also mention some limited coverage expansions that would not qualify as full ACA Medicaid expansions and would not qualify for enhanced federal matching funds. 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.
