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. In November 2017, the CMS posted revised criteria for Section 1115 waiver demonstrations. A number of states have waivers pending at CMS that include provisions not previously approved including drug screening and testing, eligibility time limits, and premiums with disenrollment for non-payment for traditional Medicaid populations. Some of the requests are part of ACA expansion waivers, while others would apply to traditional populations. On January 11, 2018, CMS posted new guidance for state Section 1115 waiver proposals to condition Medicaid on meeting a work requirement. The map below tracks states with approved Section 1115 Medicaid waivers and pending waivers (which include new waiver applications, waiver amendments, and renewals).
