Section 1915(c) Waiver Appendix K Updates​

At the beginning of the COVID-19 pandemic, the U.S. Department of Health and Human Services (DHHS) declared a national public health emergency (PHE) and relaxed certain requirements ensuring the health and safety and continued access to healthcare services for Medicaid members. In response to the federal PHE, Maine established temporary changes to its five existing federally approved section 1915(c) Home and Community-Based Services (HCBS) waivers through a standalone Appendix K: Emergency Preparedness and Response amendment.    

In accordance with the Centers for Medicare and Medicaid Services (CMS) policy, the default expiration date for Appendix K flexibilities is six months following the end of the federal PHE. However, CMS indicated in its August 2, 2023, State Medicaid Director letter (SMD #23-004) that Appendix K flexibilities may be extended past the original November 11, 2023, deadline. States can avoid a lapse in authority for Appendix K flexibilities that the state has incorporated into section 1915(c) waiver renewals and/or amendments that are still pending approval as of the November 11, 2023, default expiration date.      

Maine has submitted five-year renewal applications, and received CMS approval effective July 1, 2023, for waiver sections: 

Maine submitted amendment applications but has not yet received CMS approval for waiver sections: 

  • Section 18, Home and Community Based Services for Members with Brain Injury waiver 

  • Section 21, Home and Community Services for Adults with Intellectual Disabilities or Autism Spectrum Disorder waiver 

  • Section 29, Support Services for Adults with Intellectual Disabilities or Autism Spectrum Disorder waiver  

Guidance for Section(s) 19 and 20 Providers: 

Flexibilities not continued through Maine’s recently approved Section 19 or Section 20 1915(c) waiver renewals will revert to current rule as described in the corresponding section of the MaineCare Benefits Manual.  

The Department will issue guidance in the near future detailing the flexibilities continuing through the approved 1915(c) waiver renewals and those that will expire on November 11, 2023.  

Guidance for Section(s) 18, 21, and 29 Providers: 

Appendix K flexibilities related to Section 18, 21, and 29 are extended until such time as CMS approves the submitted 1915(c) waiver amendment applications.  

The Department will issue guidance in the near future detailing the flexibilities extending past the November 11, 2023, expiration date.
