MAC (Medicare Administrative Contractor)

Home health and hospice claims are handled by dedicated HH+H MACs: Palmetto GBA, CGS Administrators, and National Government Services, each serving an assigned group of states. Your MAC is the operational front door for claims, NOAs, medical review, and first-level appeals.
