Medicare post-acute authorization reviews & appeals

Use the instructions in the sections below to submit reviews and appeals requests for post-acute medical authorizations for Medicare members. Click on the headings to expand each section.

Note: If you have a denied medical authorization on file, submit a medical authorization appeal – not a post-claim review request.

Pre-service

Situation

You received a denial from the initial prior authorization review. 

Process

For Medicare only, pre-service authorization denials use the member appeal process.

To appeal on behalf of the member, complete and submit the Medicare Member Appeal Form, making sure to attach the Medicare Member Appointment of a Representative Form (form CMS-1696).

Post-service/pre-claim or post-claim

Retrospective authorizations

You can submit a retrospective authorization request up to 90 days after a service is rendered. If your retrospective authorization request is denied, follow the medical authorization appeal process outlined below.

  • Level I medical authorization appeal: Request within 60 days of initial decision
  • Level II medical authorization appeal: Request within 30 days of level I denial

If more than 90 days have passed since the service was rendered, you must submit a claim before following the post-claim appeal process.
