Registering for myCGS

In order to register for and use myCGS, a provider (each PTAN/NPI combination) must have a signed Electronic Data Interchange (EDI) Enrollment Agreement on file with CGS. A link to the EDI Enrollment Agreement is located on page 1 of the EDI Enrollment Packetscreenshot. If you do not already have an EDI Enrollment Agreement on file with CGS, please complete one before attempting to register for myCGS.

  3. Click on "Create Your Account" button.

    Click "Save & Proceed" to continue.

    When done, click "save & Proceed."


  8. You will receive an email that includes a 7-digit code.


  9. Enter that code on the Verify My Email page. Click the "Verify My Email" button to continue.

To gain access to provider information, your Provider Administrator may assign permissions for you to access provider accounts. You may also send a request to the Provider Administrator from your My Account tab under the myProviders sub-tab. Click on the "Add a Provider" button to complete the request.


Refer to the My Account/Add a Provider section of this manual for step-by-step instructions.

Back to the Top of the Page Top


myCGS users may have one of two roles: A Provider Administrator or a Provider User.

Provider Administrator

The first person who registers a provider's PTAN/NPI combination is considered the Provider Administrator. Provider Administrators will have access to all tabs and functions within myCGS. This person is responsible for maintaining the portal for the PTAN/NPI combination, which includes registering, granting permissions for, and deleting users.

NOTE: We suggest there be at least two Provider Administrators established for each provider office. This is especially important in the event a Provider Administrator is unable to log into myCGS on a regular basis or leaves the practice. If this happens and no one is assigned the role as an additional Provider Administrator, all established Provider Users may risk being deleted.

Provider User

Provider Users are established by the Provider Administrator and are granted rights to some/all tabs within myCGS. Those tabs for which Provider Users have not been granted access will be grayed out and will not be accessible. If you need access to tabs that are grayed out, you must request access from your Provider Administrator. (CGS does not determine access or security for Provider Users.) This is done under the My Account tab, myProviders sub-tab. (Refer to the My Account section below.) There is no limit to the number of Provider Users that can be established under the Provider Administrator.

Logging into myCGS

Once you have completed the registration process (see Registering for myCGS above), you can access myCGS at

Click on the "Log In" link.


Enter your Username and password in the appropriate fields and click "Log In."


NOTE: If you experience problems logging into your account (e.g., inactive profile, temporary lockout, incorrect password, deactivated Username, etc.) a message code will display directing you to your registered email account for specifics.

CGS recommends that all Provider Administrators and all Provider Users sign into myCGS at least once every two weeks. You must log in every 30 days to avoid deactivation. For more information, refer to the User ID Disabled section.

Multi-Factor Authentication (MFA)

MFA is a CMS requirement that provides an additional form of security to safeguard provider and patient information. The MFA verification code is a 6- or 8-digit code that must be entered before gaining access to myCGS.

During the registration process, you entered your email address and had the option of adding your mobile number and setting up the Google Authenticator app.


  • If you select either the text or email option to receive your MFA code, the 8-digit code is valid for up to 12 hours. You may reuse the same MFA code repeatedly within the 12-hour period.

    Click the button, enter the code, and click "Submit."
  • If using Google Authenticator to access myCGS, the app continuously changes to a new 6-digit code every 30 seconds.


    Enter the code and click "Submit."

    NOTE: This is THE fastest way to access the myCGS portal! For instructions, refer to Google Authenticator under the My Account section.

    Before accessing myCGS, you must acknowledge the myCGS Terms of Use.

Find Your Administrator

If at any time you need to contact your myCGS Provider Administrator but cannot log into the portal, you can find out from the log in page.

Enter your name, email address, PTAN, and NPI.

myCGS Session Timeout

For security purposes, all myCGS sessions will automatically time out after 30 minutes of inactivity. A notification box will display when you are approaching your inactivity limit. If you wish to continue your session, click "Stay and Continue," and your session will be extended.


If you are automatically logged out, you may log back in without delay.

Back to the Top of the Page Top

User ID Disabled

CMS and CGS are dedicated to keeping your information safe. To achieve this, access to myCGS must be limited to users who use the system on a regular basis.

As a result, a User ID will be disabled when it has not been used in 30 days. For this reason, CGS recommends that all Provider Administrators and all Provider Users sign into myCGS at least once every two weeks.

  • If you are a Provider User, contact your Provider Administrator if your User ID is disabled.
    • The Provider Administrator can unlock the account from the "Admin"tab and the "User Listing" sub-tab.
    • Locate the user on the "Provider User Listing" page.
    • Under the "Action" column, click on the gear icon on the line of the user.
    • Select "Unlock" to re-establish the user's access.

  • If you are one of multiple Provider Administrators and your User ID is disabled, check with another Provider Administrator for assistance. If you are the only Provider Administrator, please contact the EDI Help Desk for assistance.

Disabled IDs that are not used will eventually be terminated for inactivity. If the terminated ID belongs to a Provider Administrator, not only will that ID be terminated, but so will all User IDs assigned by that Provider Administrator. (To avoid this, please be sure to have multiple Provider Administrators on the account.)

  • Provider Administrators and Provider Users must register for myCGS again using a new Username.
  • Under the My Account tab, go to myProviders and click the "Add a Provider" button to add provider accounts. (Refer to the My Account section below for additional information.)

CGS encourages more than one Provider Administrator.

For your security, if you do not log out, myCGS will automatically time out after 30 minutes of inactivity.

You may log back in at any time.
