TLDR; This guide walks you through which portals you should register for if you are billing claims to Medicare.

Medicare claims (Part A and Part B) for each state are processed by a Medicare Administrative Contractor (MAC). Each MAC has their own provider portal, to figure out the portals you need to sign up for you need to figure out the MAC for the state you’re seeing Medicare patients in. As a reminder Part A is for Hospital Claims and Part B is for Professional Claims (CMS-1500)

Use this guide to figure out the MAC for each of the states you’re seeing Medicare patients in. Search (Ctrl/Cmd + F) for the state you’re seeing patients in and you’ll find the name of the MAC for Part B claims along with a link to the MAC’s secure provider portal.

For each state you’ll also find the Payer ID you should send claims to. For states with multiple payer IDs, please use this guide from CMS. You’ll need to identify your county/locality based on your servicing address.
