The Affordable Care Act substantially transformed the market for non-group private health insurance, introducing new consumer protections and coverage standards and establishing Health Insurance Marketplaces.

This Issue Brief presents current estimates of enrollment in health insurance coverage obtained through the ACA Marketplaces and the Medicaid expansion and the subsequent reductions in state-level uninsured rates since the ACA was implemented in 2014.

Key Points

The Inflation Reduction Act’s (IRA) expanded financial assistance in Medicare’s Low-Income Subsidy (LIS) Program would have benefited nearly 461,000 Partial LIS enrollees had the provision been in effect in 2020. An additional 2.9 million Part D enrollees who were eligible but not enrolled in LIS would also have benefited from the program.

The child care subsidy program provides critical support to families to support parental labor force participation as well as child development. This study provides a historical view of the socioeconomic and demographic characteristics of parents who received subsidies over the 2009-2013 period.

Increasing availability of linked child welfare and Medicaid data can advance research on the intersections of child welfare and Medicaid. The project, Child and Caregiver Outcomes Using Linked Data (CCOULD), developed a research-use dataset combining child welfare records and Medicaid claims for children and families involved in child welfare systems in Florida and Kentucky.

This research brief uses claims data from the Medicaid and Children's Health Insurance Programs to examine the behavioral health diagnoses and treatment services received by children and youth involved with the child welfare system in 2019.

This report is the third in a series of reports commissioned by the Office of the Assistant Secretary for Planning and Evaluation (ASPE) from the RAND Corporation addressing state all payer claims databases (APCDs).

This report presents the set of guiding principles for linking state Medicaid data with birth certificates that was developed by state and national experts and leaders. These guiding principles can be implemented to create a multistate linked database that researchers would be able to access and use for research on maternal health, including patient-centered outcomes research (PCOR).

Home and community-based services (HCBS) are a range of medical and non-medical services provided in the home and community that support individuals with functional limitations, enabling them to reside in the community rather than in institutional settings.
