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..

In this Policy Watch we explore the potential impact of the expiration of the American Rescue Plan Act’s enhanced financial help and new eligibility for the Affordable Care Act’s health insurance Marketplace federal subsidies.

February 20, 2019 Issue Brief
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.

This poll also examines the public’s favorability toward expanding the role of public health care programs, and majorities across partisan groups have a favorable opinion of programs such as Medicare buy-in and Medicaid buy-in, with a national Medicare-for-all being less popular but still receiving a majority of support overall.
