Medicare Administrative Contractors (MAC)

A Medicare Administrative Contractor (MAC) is a private health care insurer that has been awarded a geographic jurisdiction to process Medicare Part A and Part B (A/B) medical claims or Durable Medical Equipment (DME) claims for Medicare Fee-For-Service (FFS) beneficiaries.  The U.S. Centers for Medicare & Medicaid Services (CMS) relies on a network of MACs to serve as the primary operational contact between the Medicare FFS program and the health care providers enrolled in the program. MACs are multi-state, regional contractors responsible for administering both Medicare Part A and Medicare Part B claims. 

Which MAC Am I In?

Want to know which MAC jurisdiction you're in? View the A/B MAC Jurisdictions Map as of June 2019. Click here to look up Local Coverage Determinations (LCDs).

The purpose of the MAC Resource Groups (MRGs) is to expedite your need for accurate local Medicare reimbursement information. Our goal is to have information that is MAC-specific flow to programs and for questions/issues from programs to flow up to your state MRG representative to your AACVPR Liaison Task Force member and to the national level when appropriate.
