Medicaid and the Road Ahead: Spending Cuts, Work Requirements and What’s Next for States, Providers and Families

Event Date:

Passed last year, President Trump’s One Big Beautiful Bill Act made significant changes to Medicaid—the primary insurance provider for health and long-term care for people with low incomes. These changes are expected to lead to coverage loss for many current enrollees and will reduce funding for Medicaid, placing new financial pressures on states and health care providers. On July 23, KFF and States Newsroom hosted an event focused on the impacts of work requirements and other federal policy changes on states, health care systems, and people.
