So that means you need to know who your MAC is. MAC is short for Medicare Administrative Contractor.

This is essentially the “middle man” that is contracted by CMS (Centers for Medicare Services) to process your Medicare claims.

In fact, your MAC is also the organization that your Medicare enrollment application goes to and the organization that you will be contacting for all Medicare related matters.

Who your MAC is all depends on where you are in the country. I’m going to tell you exactly who is your MAC and what are the important contact websites and numbers you will need.

You need this information because when you are ready to bill, and even before that, this is the website where you will be able to check patient eligibilities, follow up on claim information, and even see what your Medicare payments and deposits are going to be.
