Instructions For Requesting Medicare Secondary Payer (MSP) Adjustments

In order to provide better customer service, reduce phone calls, and have you provide appropriate documentation, we have developed a new process for requesting MSP adjustments. This will allow the MSP Department to more efficiently adjust your claims.

MSP adjustments (type of bill xx7) can be submitted EMC or hardcopy. MSP adjustments are not accepted via fax or Direct Data Entry

Checks for Adjustments

Please do not send checks to WPS Medicare on claims unless requested directly from WPS Medicare or regarding a date of service that is over four years old. Providers must verify that the claim can't be adjusted before submitting a check by contacting Customer Service. If a check is requested from WPS Medicare, please include complete documentation (HIC, DCN, date of service and NPI number) along with a contact name and phone number.

For faster processing of your adjustments we encourage you to submit your adjustments via EMC.

Mail the information to:

WPS Medicare
Medicare Secondary Payer
PO Box 8799
Madison WI 53708-8799

As the provider, you are responsible for checking the MSP screen on Common Working File (CWF) to ensure the information is accurate. If the information is correct, you may proceed with requesting your adjustment. If the screen is incorrect, you must call the Coordination of Benefits Contractor (COB) at 1-800-999-1118 to update the CWF. Once the screen has been updated by (COB) you may proceed with requesting your adjustment. Until this has been done by COB, our MSP Department is unable to adjust the denied claims and unable to assist you. However, if you do not have access to CWF you may contact the MSP Department at 1-866-518-3284 and we will check CWF for you.

For IRS/SSA/Data Match you must send a letter from the employer (on their letterhead) to the COB Contractor at the following address:

Coordination of Benefits Contractor
PO Box 5041
New York, NY 10274-5041
