Medicare Coordination of Benefits Logo

Welcome to Workers' Compensation Agency Services






This section will provide you with information on the Coordination of Benefits (COB) program and assist you with meeting your responsibilities and obligations under the Medicare Secondary Payer (MSP) laws.

The COB Contractor is committed to providing all of our customers with the information they need to fulfill their obligations under MSP laws. You play a vital role in building and maintaining the integrity of Medicare payments. If you do not understand or meet your responsibilities in the MSP process, benefit dollars will be needlessly depleted from the Medicare Trust Funds. Through this Web site, we hope to improve your understanding of MSP laws and processes.

If you have any questions regarding the COB MSP Claims Investigation process, please call the COB Contractor's Customer Service Department toll-free at 1-800-999-1118 or TTY/TDD: 1-800-318-8782 for the hearing and speech impaired. Customer Service Representatives are available to assist you Monday through Friday, from 8:00 a.m. to 8:00 p.m., Eastern Time, except holidays.
