What does CMS delegate to MACs or FIs?

The delegation of the administration of the Medicare program to MACs (Medicare Administrative Contractors) or FIs (Fiscal Intermediaries) is a crucial aspect of how the Centers for Medicare & Medicaid Services (CMS) operates. MACs and FIs are responsible for processing Medicare claims, making payment determinations, and ensuring compliance with Medicare regulations. This delegation allows CMS to efficiently manage the vast scope of the Medicare program by relying on these contractors to handle operational tasks, which include outreach, education, and claims processing.

By assigning this responsibility, CMS can focus on overarching policy development and program integrity while ensuring that beneficiaries receive timely and accurate services. This structure helps maintain the effectiveness of the Medicare program and ensures adherence to the complex regulations that govern it. In contrast, the other options pertain to areas of healthcare that CMS does not delegate to these contractors, as they relate to different aspects or other programs outside of Medicare's scope.
