Section 1115 Medicaid demonstration waivers offer states an avenue to test new approaches in Medicaid that differ from what is required by federal statute.

In 2025, many issues are at play that could affect Medicaid coverage, financing, and access to care.
With Donald Trump returning to the presidency and Republican control of the Senate and House, work requirements are likely to be back on the agenda—through federal legislation or Medicaid waivers.

Section 1115 Medicaid demonstration waivers offer states an avenue to test new approaches in Medicaid that differ from what is required by federal statute, so long as the approach is likely to “promote the objectives of the Medicaid program.” As with broader Medicaid policy, the future landscape of Section 1115 waivers depends on the outcome of the November 2024 presidential election as a new administration could focus on different priorities, rescind existing guidance, or withdraw already-approved waivers. This waiver watch summarizes five key areas of difference in 1115 waiver policy and waiver approvals under the Trump and Biden-Harris administrations.
In his latest column, KFF President and CEO Drew Altman writes about the fundamentally different world views of the Medicaid program by Republicans and Democrats and how those ideological divides have affected policy proposals, sometimes despite the program's popularity and broad reach.
