Why this denial happens
- The diagnosis on the claim does not support the service under the payer’s policy.
- The note does not document why the service was needed (symptoms, history, prior treatment).
- The service exceeded frequency limits in the payer’s coverage policy.
- For Medicare, the service is not covered in that situation and no ABN was signed.
How to fix a claim that was denied
- Read the payer’s coverage policy for the service and compare it with the note.
- If the documentation supports the service, appeal with the relevant note, results and the policy criteria it meets.
- If the diagnosis was coded incompletely, correct it if the record supports a more specific code, and resubmit.
- For Medicare, if a valid ABN was signed, the patient can be billed; without one, usually not.
How to prevent it
- Document the reason for each service in the note, not only the diagnosis.
- Check the payer’s coverage policy for frequently denied services.
- Give Medicare patients an Advance Beneficiary Notice before services Medicare may not cover.

Common questions
What is an ABN?
An Advance Beneficiary Notice of Noncoverage is a CMS form given to a Medicare patient before a service Medicare may not cover. A valid signed ABN lets the practice bill the patient if Medicare denies.
How do I win a medical necessity appeal?
Answer the payer’s stated reason with the specific documentation that meets its coverage criteria: the note, test results and prior treatments, clearly labeled.
