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. 

Demand Letter and Voluntary Refunds
CGS, LLC
DME MAC Jurisdiction C
PO Box 955152
St. Louis, MO 63195-5152
