Welcome to Attorney Services

"To assure that claims are paid right the first time, every time."

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 our customers with all information needed to fulfill their obligations under MSP laws. Attorneys, beneficiaries, insurers, providers, and Medicare contractors each play a vital role in building and maintaining the integrity of Medicare payments. If any one of these entities does not understand or meet the responsibilities of their role 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. We will initiate and maintain an open line of communication, so that we can all function at optimum efficiency. When we accomplish this, we will ultimately help protect your client, the Medicare beneficiary. Click below to get more information on the topic of your choice.
