Home COVID-19

In response to the novel coronavirus (aka COVID-19) several states have taken advantage of the opportunity to temporarily amend Medicaid waiver programs. This is being done using three available vehicles: Appendix K, 1135 waiver flexibilities, and 1115 demonstrations.

  • Appendix K amend existing 1915(c) waivers;
  • 1135 Waivers temporarily waive/modify Medicare, Medicaid, and CHIP requirements; and
  • 1115 demonstrations allow states to request a new Medicaid/CHIP section 1115(a) demonstration or amend/extend current 1115(a) demonstration.

In addition to these flexibilities, the Centers for Medicare and Medicaid Services have been empowered to retroactively grant blanket waivers from 3/1/2020 until the end of the emergency declaration.

The State of the States in Intellectual and Developmental Disabilities, in an effort to understand changes that are occurring in the IDD space, is compiling state applications and approval letters. By clicking on each state or territory below, you will be able to access Appendix K application summaries along with a link to the original application and approval letters.
