MACs are responsible for which functions?

• A. Manage Patient Appointment Scheduling Systems
• B. Process Medicare Claims, Enroll Health Care Providers in the Medicare Program, Educate Providers, Handle Claims Appeals, Answer Beneficiary and Provider Questions.
• C. Issue Hospital Facility Accreditation
• D. Review Medical Records for Quality Assurance

Answer: (B)

Medicare Administrative Contractors (MACs) are the entities CMS hires to manage the administrative side of the Medicare program. They handle the day‑to‑day work that keeps Medicare payments moving and policy knowledge flowing. Specifically, MACs process Medicare claims, enroll health care providers in the Medicare program, educate providers about Medicare rules, handle claims appeals, and answer questions from both beneficiaries and providers. This combination directly reflects the administrative scope CMS assigns to MACs.

Other tasks listed don’t fit this role. Scheduling patient appointments is a clinical office function, not a Medicare contractor duty. Hospital facility accreditation is carried out by accreditation bodies, with CMS oversight as applicable, not by MACs. Reviewing medical records for quality assurance is typically done by quality-focused programs or other CMS contractors, not the general claims and enrollment functions that define MAC work.
