Working With Your Medicare Administrative Contractor (MAC)

Many Services Are Available Through the MAC

Although Medicare is a Federal program, providers generally interact with the designated Medicare Administrative Contractor (MAC) for their jurisdiction. MACs act on behalf of the Center For Medicare and Medicaid Services (CMS) in many capacities in Part B Medicare.

What you'll learn in this module

This module outlines the Provider-MAC relationship, the duties that the MAC performs for the provider, and how providers interact with this important payer, both on the national and local levels. The resources that are provided are very useful in your practice. Because your MAC processes your Medicare claims, it's critical to understand their role and how to interact with them.
