What is a Medicare Administrative Contractor?

A Medicare Administrative Contractor (MAC) is a private health insurance company that contracts with Medicare to process and pay Medicare Part A and Part B claims for specific geographic regions. MACs handle claims processing, provider enrollment, customer service, fraud detection, and appeals for both healthcare providers and Medicare beneficiaries. These contractors serve as the primary point of contact between Medicare and the healthcare providers who treat Medicare patients.
