Dispute a denied Medicare claim

Page last updated on: 2/02/26

The Centers for Medicare & Medicaid Services (CMS) requires Medicare Advantage Organizations (MAOs), including Priority Health Medicare, to have a provider claim dispute process that includes:

  • Asking for a review of claims payment
  • Making a claim dispute on behalf of a member

Plans included:

This CMS process applies to Medicare-covered medical services and supplies for patients covered by: 

  • Priority Health Medicare Advantage plans
  • Employer group Medicare plans covering their retirees

Step 1: Level 1 claim dispute

You must wait 45 days after submitting a Level 1 claim dispute (formerly called Review).

You must complete the Level 1 claim dispute process and receive a decision before submitting a Level 2 claim dispute. (The Level 1 claim dispute process for Medicare is the same as for commercial plans).

Step 2: Level 2 claim dispute

Definition of a Level 2 claim dispute 

A Level 2 claim dispute (formerly called Appeal) is a formal request by a provider for Priority Health to re-examine its initial adverse determination of a claim after a Level 1 claim dispute process is completed. If you haven't completed Level 1 claim dispute, we won't process your Level 2 dispute.

A Level 2 dispute must include additional documentation to support services rendered or payment expected. We won't accept disputes from providers that did not perform the service.

Non-disputable denials

Inaccurate coding or billing denials for services are not disputable denials. These denials require correction through corrected claim process.
  • Missing modifiers 
  • Missing laterality in diagnosis or modifier 
  • Incorrect place of service 
  • APC Edit Claim Denials
  • Incorrect procedure codes for governmental claims (i.e. G-Codes) 
This is not an all-inclusive list

Deadline for Level 2 claim disputes

You must submit your Level 2 claim dispute within 180 days of the remittance advice.

What will you need?

When you submit your Level 2 claim dispute, you must upload additional documentation to support the services rendered or payment expected. Here’s our tips for choosing what documents to upload:

  • Claim ID for the most current claim. We’ll close claim disputes without review when a claim is resubmitted after the dispute was filed.
  • Denial reason applied to the claim or claim line.
  • Attach any Policy or clinical guidelines applicable to the denial.
  • Attach any regulatory, billing, coding guidelines or contract language.
  • Supporting documentation applicable to the service under dispute. We’ll close claim disputes submitted with the full medical record.
  • Summary of why you believe the claim didn’t process in accordance with the guidelines, policy and/or contract. This should be very specific. We’ll close claim disputes with statements such as “this is coded correctly” or “please review records” as these don’t support a claim dispute rationale.
