A new health care bill recently introduced by a number of senators led by Senators Lindsey Graham and Bill Cassidy would repeal major elements of the Affordable Care Act (ACA), make changes to other ACA provisions, and fundamentally alter federal Medicaid financing. In this brief, we estimate changes in federal funding due to the new block grant program and the Medicaid per enrollee cap on a state-by-state basis under the Graham-Cassidy bill relative to current law. We estimate that the Graham-Cassidy proposal would reduce federal funding for health coverage by $161 billion nationally from 2020-2026, with substantial variation across states.
