Denial Code: CO-195 - Refund issued to an erroneous priority payer

Dear Appeals Department,

I am writing to appeal the denial of the above-referenced claim, which was denied with code CO-195: "Refund issued to an erroneous priority payer".

We are appealing the denial under code CO-195 for the services rendered. A refund has been successfully processed and returned to the erroneous payer following a redetermination of the patient's Coordination of Benefits. In accordance with CMS Coordination of Benefits guidelines and standard industry billing practices, we have identified the correct priority payer and submitted this corrected claim along with the refund receipt and documentation confirming active primary coverage. We request that the claim be reviewed and processed for payment as the primary carrier.

Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].

We respectfully request that you reprocess this claim for payment.

Sincerely,

[Your Name]
