CO 39 Denial Code - Understand & Resolve
CARC 39 means that the claim was denied because the services were not authorized or pre-certified when the request was made. This usually happens when the payer requires prior approval for certain procedures or services, but the request was denied at that stage.
Who Pays: Group Code Liability
For CARC 39, the group code is CO, indicating a contractual obligation where the provider must write off the charge and cannot bill the patient.
Why Claims Get Code 39
- Pre-authorization request was submitted after the service was provided.
- Authorization request was incomplete or missing required information.
- The service is not covered under the patient's plan and was denied during pre-certification.
- The provider did not follow the specific payer's pre-certification process.
- Authorization was requested for a different service or procedure than what was performed.
How to Fix & Resubmit
- Verify if the pre-authorization was indeed denied and check the reason for denial.
- Contact the payer to confirm the denial reason and whether any additional documentation could change the decision.
- If the denial was due to a missing or incorrect authorization, gather the correct information and submit a corrected claim if allowed.
- If the service was not covered and cannot be authorized, write off the amount as per contractual obligation.
- Document the denial reason and any communications with the payer for future reference.
Corrected Claim or Appeal?
For CARC 39, a corrected claim is only appropriate if the denial was due to incorrect or incomplete information that can be rectified. Otherwise, if the service is non-authorizable, no appeal is possible and it is a contractual adjustment.
Preventing Future 39 Denials
- Ensure all services requiring pre-authorization are identified before scheduling.
- Train staff on payer-specific pre-certification requirements and processes.
- Implement a checklist for authorization requests to ensure completeness before submission.
- Regularly audit denied claims for authorization issues to identify patterns and retrain staff as needed.
