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..

More than four years after the implementation of the Medicaid expansion included in the Affordable Care Act, debate and controversy around the implications of the expansion continue. Despite a large body of research that shows that the Medicaid expansion results in gains in coverage, improvements in access and financial security, and economic benefits for states and providers, some argue that the Medicaid expansion has broadened the program beyond its original intent diverting spending from the “truly needy”, offers poor quality and limited access to providers, and has increased state costs. New proposals allow states to implement policies never approved before including conditioning Medicaid eligibility on work or community engagement. New complex requirements run counter to the post-ACA movement of Medicaid integration with other health programs and streamlined enrollment processes. This brief examines evidence of the effects of the Medicaid expansion and some changes being implemented through waivers. Many of the findings on the effects of expansion cited in this brief are drawn from the 202 studies included in our comprehensive literature review that includes additional citations on coverage, access, and economic effects of the Medicaid expansion.

Given the Trump Administration’s promotion of short-term limited-duration (STLD) health insurance policies, this brief examines what they mean for people with HIV. The analysis assesses whether people with HIV could enroll in STLD plans by applying to 38 plans across five states and getting in each case. It also assesses whether such plans could meet basic HIV care and treatment needs for someone diagnosed once enrolled.
