Which myCGS Did You Access?

CGS administers multiple Medicare contracts, not just the Jurisdiction 15 (J15) contract. As such, we have two completely separate versions of myCGS—one for J15 A/B MAC (Part A, Part B, and Home Health & Hospice) and one for the Durable Medicare Equipment Medicare Administrative Contract (DME MAC JB and JC). The two versions of myCGS look similar, but they are actually separate applications.

When you access myCGS, it's important to make sure you are using the J15 A/B MAC version of myCGS. A valid ID for the J15 A/B MAC myCGS will not work in the DME MAC myCGS, and vice versa.

To make sure that you are accessing the J15 A/B MAC version of myCGS, we recommend the following:

  • Always access myCGS from the J15 Part A, J15 Part B, or J15 HHH web pages. Click on the myCGS link in the left column. Do not attempt to access myCGS directly from an internet search site (i.e., Google, Bing, etc.).
  • Look at the URL in your internet browser's address bar:

    The J15 A/B MAC myCGS URL is

    The DME MAC myCGS URL is https://mycgsportal.comExternal Website

  • On the login page, look in the "Who Can Register for myCGS?" section. The text will state either "Jurisdiction 15 A/B MAC" or "DME MAC Jurisdiction B and C."

For more information about myCGS, be sure to check out the myCGS User Manual and various job aids which are available under the J15 Part A, J15 Part B, or J15 HHH myCGS webpage.
