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.
