Medicare Administrative Contractors (MACs) are entities contracted by the Centers for Medicare & Medicaid Services (CMS) to process Medicare claims and administer the Medicare program within designated geographic regions across the United States. MACs play a crucial role in ensuring the efficient and accurate processing of claims submitted by healthcare providers, including hospitals, physicians, and suppliers.
