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.” Waivers generally reflect priorities identified by states as well as changing priorities from one presidential administration to another. The Biden administration encouraged states to propose waivers that expand coverage, reduce health disparities, advance whole-person care, and improve access to behavioral health care. Looking ahead, the new Trump administration’s waiver priorities will likely differ significantly from those of the Biden administration. However, it is unclear how the Trump administration will treat certain waivers promoted and approved by the Biden administration.
