Administrative Hearings

The Michigan Administrative Hearing System (MAHS) for the Department of Health and Human Services (DHHS) provides administrative hearings to those requesting a hearing or those who do not agree with a decision made by the DHHS contracted agency (any agency, organization, or health plan contracted by the DHHS that either determines eligibility for a department program, or delivers a service provided under a department program to a beneficiary, patient, or resident). The MAHS for the DHHS issues timely, clear, concise, and legally accurate hearing decisions and orders. Read more about MAHS for DHHS and Administrative Hearings.
