What is a MAC, and why does it matter for coverage?
A Medicare Administrative Contractor (MAC) is a private company CMS contracts to process Part A and Part B claims for a defined multi-state jurisdiction. There are 12 A/B MAC jurisdictions run by 7 companies. Each MAC publishes its own Local Coverage Determinations (LCDs) and Billing & Coding Articles, which set the covered ICD-10 diagnoses for physician-administered drugs in that region. Because coverage is local, a diagnosis that's covered for a drug in one state may be denied in another — always bill against the article for your MAC. Our drug coverage pages show one MAC's list and link back here so you can confirm yours.
Frequently asked questions
- What is a Medicare Administrative Contractor (MAC)?
- A MAC is a private company CMS contracts to process Medicare Part A and Part B claims for a defined multi-state jurisdiction. There are 12 A/B MAC jurisdictions run by 7 companies. Each MAC sets local coverage (LCDs and Billing & Coding Articles) for its region, so covered diagnoses for a drug can differ by MAC.
- Why does my MAC matter for drug coverage?
- Coverage for physician-administered Part B drugs is set locally by each MAC. A diagnosis covered by one MAC may not be covered by another, so you must bill against the article that applies in your state.
