PR-50: These are non-covered services because this is not deemed a 'medical necessity' by the payer.
The payer reviewed the diagnosis and service billed and determined the clinical documentation does not meet its medical necessity criteria for this service. This is a clinical judgment denial, not a data error.
What the group code means
- PR
- Patient Responsibility. The amount may be billed to the patient.
Why it fires
- The diagnosis does not meet the payer's LCD, NCD, or medical policy criteria for the service
- Documentation submitted, if any, did not demonstrate the clinical indications required
- The service exceeds frequency or step-therapy requirements in the payer's medical policy
Corrective actions, ranked
- 1
Pull the payer's medical policy or LCD
Compare the documented clinical indications against the specific criteria the payer requires for coverage.
- 2
Submit medical records
If the documentation actually supports necessity but was not reviewed, submit an appeal with the complete chart note, test results, and any specialist letters.
- 3
Check for an ABN
For Medicare, confirm whether an Advance Beneficiary Notice was signed. If so, the patient can be billed appropriately with modifier GA.
Is it worth appealing
This is one of the most appeal-worthy denials when the clinical documentation genuinely supports necessity. Submit detailed records and the physician's clinical rationale.
