The Medicare Administrative Contractors (MACs) handle which aspect of Medicare?

• A. Enforce all Medicare legislation.
• B. Oversee private Medicare Advantage networks.
• C. Administer the Medicare program and handle claims processing.
• D. Regulate pharmaceutical pricing.

Answer: (C)

Medicare Administrative Contractors administer the traditional Medicare program by processing and paying claims for Part A and Part B services, handling enrollment and eligibility, and supporting day-to-day operations and program integrity for CMS. They are the hands-on entities that ensure providers get paid for covered services and that the claims workflow runs smoothly. They do not enforce all Medicare legislation, oversee private Medicare Advantage networks, or regulate pharmaceutical pricing—the first is a broader regulatory role, the second concerns privately run MA plans under CMS, and the third involves drug pricing managed through Part D plans and CMS oversight.
