The Affordable Care Act's (ACA) Medicaid expansion resulted in substantial gains in coverage. However, little research has documented eligibility or participation rates among eligible adults in the post-ACA period in part because of the complexities involved in assigning eligibility status. We used simulation modeling to examine Medicaid eligibility and participation during 2014 to 2017. More than one in five adults were Medicaid eligible in expansion states in the post-ACA period. In contrast, about one in 30 adults were Medicaid eligible in nonexpansion states. While eligibility rates differed substantially by expansion status, participation rates among Medicaid-eligible adults were similar in both sets of states (44% to 46%). These estimates indicate that differences in eligibility rather than in participation rates explained differences in enrollment between expansion and nonexpansion states during the study period. Participation in Medicaid is expected to grow during the coronavirus pandemic. Our study provides baseline estimates for future analyses of enrollment trends.

Prior to the Affordable Care Act, one in three young adults aged 19 to 25 years were uninsured, with substantial racial/ethnic disparities in coverage. We analyzed the separate and cumulative changes in racial/ethnic disparities in coverage and access to care among young adults after implementation of the Affordable Care Act's 2010 dependent coverage provision and 2014 Medicaid and Marketplace expansions. We find that the dependent coverage provision was associated with similar gains across racial/ethnic groups, but the 2014 expansion was associated with larger gains in coverage among Hispanics and Blacks relative to Whites. After the 2014 expansion, coverage increased by 11.0 and 10.1 percentage points among Hispanics and Blacks, respectively, compared with a 5.6 percentage point increase among Whites. The percentage with a usual source of care and a recent doctor's visit also increased more for Blacks relative to Whites. Increases in coverage were larger in Medicaid expansion compared with nonexpansion states for most racial/ethnic groups.
