State Level

This briefing looks into the key challenges facing states, including working within state legislative cycles against tight deadlines in the federal law, creating new roles at the state level as state budgets are being squeezed, and others.

The Alliance for Health Reform, Robert Wood Johnson Foundation and the Association of Health Care Journalists sponsored this live webinar on March 27, 2012, to take a look at what’s happening in the states with implementation of the Patient Protection and Affordable Care Act.

In his latest column, President and CEO Drew Altman shows how proposals contained in the House reconciliation bill could result in a one-third reduction in ACA Marketplace enrollment. “While all eyes are on the big Medicaid cuts being proposed in the House,” he writes, “significant changes are also being proposed that together would dramatically reduce enrollment in the ACA Marketplaces.”

Through regulations and the House budget reconciliation bill, significant changes are being considered by Congress and the Trump Administration for how the Affordable Care Act’s health insurance Marketplaces would work. To examine how these changes could reshape the ACA’s Marketplaces, KFF held a virtual briefing on June 11 featuring leaders from two state-based Marketplaces to get perspectives from the field.

In his latest column, President and CEO Drew Altman discusses how, with nearly half, or about 10 million MAGA supporters and Republicans receiving coverage through the ACA Marketplaces, the policy changes and cuts being considered by Republicans to the Marketplaces will directly affect their own voters. Altman writes: “Republicans are no longer interested in repealing the ACA but seem comfortable shrinking it significantly if they can, so long as they don’t touch protections for pre-existing conditions, which is now a political third rail.”

Prior KFF analysis allocated CBO’s federal Medicaid spending reductions and enrollment losses across the states, and this policy watch builds on that analysis to examine the potential impacts in expansion states compared with non-expansion states.

This analysis of enrollment in Affordable Care Act (ACA) Marketplace health plans finds a record 24.3 million people enrolled in 2025, more than double the total in 2020, with most of the growth occurring in states won by President Trump in the 2024 election. In six states, enrollment more than tripled from 2020 to 2025: Texas, Mississippi, West Virginia, Louisiana, Georgia, and Tennessee.

House Republicans have passed a reconciliation package (the “One Big Beautiful Bill Act”) that would make significant changes to Medicaid and the Affordable Care Act (ACA) Marketplaces and increase the number of people without health insurance by an estimated 10.9 million. This analysis estimates state-level increases in the number of uninsured people due to this legislation, along with other changes to the Marketplace, including the expiration of the enhanced premium tax credits.
