Office of Medicare Hearings and Appeals (OMHA)

Level 4 Appeals

If you are not satisfied with your Level 3 decision or dismissal, you may request that the Medicare Appeals Council (MAC) review the ALJ's decision. 

The Medicare Appeals Council (MAC):

  • Conducts the Level 4 appeal, and is
  • Part of the Departmental Appeals Board of the Department of Health and Human Services (HHS), and is
  • Independent of OMHA and its ALJs.

Note:  A party does not have the right to seek MAC review of an ALJ's remand to a QIC or an ALJ's affirmation of a QIC's dismissal of a request for reconsideration.Skip navigation.
