Section 1115 Medicaid demonstration waivers provide states an avenue to test new approaches in Medicaid that differ from federal program rules. While there is great diversity in how states have used waivers over time, waivers generally reflect priorities identified by states and the Centers for Medicare and Medicaid Services (CMS). On March 14, 2017, the CMS sent a letter to state governors that signaled a willingness to use Section 1115 authority to support work requirements and the alignment of Medicaid programs with private insurance policies.
