To expedite the posting of checks sent to CGS in response to an overpayment, ensure the following information is included:
- Patient's Medicare Number
- Date(s) of service
- Claim number (DCN or CCN)
- Reason for refund
- Refund amount
- For refunds that are MSP-related, include the EOB or the payment allowed and paid by the primary insurer
