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.

All About Advance Directives

An Advance Directive (also known as a Durable Power of Attorney) is a legal document that allows you to name a Patient Advocate and gives the Advocate specific permission (or power) to make decisions about your medical and/or mental health care. These powers are only active when you are unable to make these decisions for yourself.

If you’re interested in more information about how to identify a Patient Advocate and/or set up an Advance Directive, you can contact the ISK Customer Services office. Please click here for more information.
