More than a decade after its enactment, tens of millions of people nationwide rely on coverage options created through the Affordable Care Act of 2010 (ACA). The law has survived multiple court challeges at the U.S. Supreme Court and repeated attempts by Republicans in Congress to repeal it. Subsequent legislation has scaled back some aspects of the law and expanded others, including by the COVID-19 relief bill, the American Response Plan Act of 2021. This page highlights relevant analysis about the ACA and proposed and enacted changes to it..

“Partial Medicaid Expansion” with ACA Enhanced Matching Funds: Implications for Financing and Coverage
The Affordable Care Act (ACA) provides enhanced federal matching funds to states that expand Medicaid to nonelderly adults up to 138% of the federal poverty level (FPL, $17,236/year for an individual in 2019). The ACA enhanced match (93% in 2019, and 90% in 2020 and thereafter) is substantially higher than states’ traditional Medicaid matching rate. A few states have sought Section 1115 demonstration waiver authority from the Centers for Medicare and Medicaid Services (CMS) to receive the substantially higher ACA enhanced match while limiting coverage to individuals at 100% FPL, instead of covering the full 138% FPL ACA group. To date, CMS has allowed states to receive the ACA enhanced Medicaid matching funds only if the entire expansion group is covered. CMS has not approved waiver requests seeking enhanced ACA matching funds for a partial coverage expansion in Arkansas or Massachusetts, while a request is pending in Utah. This brief explores the current rules for partial expansion and explains some of the potential implications for financing and coverage if CMS approves waivers to allow for partial expansion with enhanced matching funds.
