What is the role of Medicare Administrative Contractors (MACs)?

• A. To create Medicare legislation.
• B. To manage private insurance networks for Medicare Advantage.
• C. To administer the Medicare program and handle claims processing.
• D. To set prescription drug prices.

Answer: (C)

Medicare Administrative Contractors are private organizations contracted by CMS to run Medicare operations in specific regions. Their main function is to administer the Medicare program and handle claims processing—reviewing submitted claims for coverage, applying Medicare rules and payment rates, and issuing payments or denials. They also manage provider enrollment, verify eligibility, and provide help to beneficiaries and providers, ensuring claims move smoothly from submission to payment. In addition, they perform program integrity activities to detect improper billing and support related audits and appeals as needed. They do not create Medicare legislation, they don’t manage private networks for Medicare Advantage plans, and they don’t set prescription drug prices; those areas are handled through separate CMS processes and private Part D sponsor arrangements.
