Reminder: Where to Send Refund Checks

CGS often receives Medicare refund checks mailed to their corporate office instead of the appropriate PO Box. This causes a delay in processing of your check. As a reminder, when you need to send a check to make a payment as a result of a Medicare demand letter, or if you have identified a Medicare overpayment and are sending a voluntarily refund check, be sure to mail it to the appropriate PO Box below.

E-Offset myCGS Option

Providers may also use the myCGS Web Portal to request an immediate offset related to a demand letter, or authorize a permanent request for all future demand overpayments. Refer to the myCGS eOffsets Job AidPDF for additional information.
