Registering for myCGS

In order to register 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 one of the EDI Enrollment Packet. If you do not already have an EDI Enrollment Agreement on file with CGS, please complete one before attempting to register for myCGS.

Registration Process

  1. Navigate to the myCGS Log-In page
  2. Click on "Register for myCGS"
  3. To complete your registration for myCGS, enter the information listed below.
    1. Provider Name
    2. Contact Name, Last and First
    3. E-Mail Address
    4. Phone Number
    5. Extension
    6. I am/work for: (select "Provider", "Billing Service" or "Clearinghouse")

    8. NPI (This is your National Provider Identifier number.)
    9. Tax ID (This is your Tax Identification number.)
    10. Most Recent Medicare Payment Amount Received (If you received more than one payment on the same day, use the amount with the highest check number. Contact the EDI Help Desk if you need assistance determining the most recent payment amount.))

  7. Once you click on the validation link, you will be taken back to the myCGS portal.
  8. Your profile has now been verified.

NOTE: If you try to log into myCGS before you have accessed the validation link, you will see the profile screen where you can update or correct your e-mail address, if needed. If your e-mail address is correct, you may click on the link to request a new e-mail. Verify that your e-mail address is correct on your profile before calling the EDI Help Desk for assistance. If you are sure your e-mail address is correct, but you do not receive your e-mail, your company's e-mail security settings may need to be updated to allow incoming e-mails from myCGS.

Unsuccessful Registration

If you entered registration information incorrectly, myCGS will display an error message in RED at the top of the screen. (Remember, you must have an EDI Enrollment Agreement on file with us to successfully register.) Carefully review the error message and correct the information. If you have verified the information entered is correct and you are still unable to register, contact the EDI Help Desk for assistance.

User ID Assignment

Once you have successfully registered, you will be assigned a Provider Administrator User ID. (Refer to the Roles section.)

In some cases, a User ID will begin with what appears to be the letter 'O'. Please note this is the number zero (0). Using the letter 'O' instead of the number '0' will not allow you access to myCGS.

You will then be asked to choose your password and answer your security questions. (Refer to the User ID Passwords and User ID Security Questions sections).

Once the Provider Administrator has established his/her security, the Provider Administrator can create User IDs for additional staff to access myCGS.

Back to the Top of the Page Top


myCGS users are assigned 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, 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 which are grayed, you must seek access from your Provider Administrator. (CGS does not determine access or security for Provider Users.) There is no limit to the number of Provider Users that can be established under the Provider Administrator.

Logging Into myCGS

If you were assigned a password by your Provider Administrator and this is the first time you are logging in, you will be prompted to agree to the "Terms of Use," change your password, and choose your security questions and answers. (See the User ID Passwords and User ID Security Questions sections.)

Once you have received your User ID, created your password, and selected and answered your security questions, you can access myCGS at

Click on the "Log In" link.

Screenshot 5

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

Screenshot 6

CGS recommends that all Provider Administrators and all Provider Users sign into myCGS at least once every two weeks. 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 an eight-digit code that must be entered before gaining access to myCGS.

During the registration process, you were required to identify how you want myCGS to send the MFA code, either by text, email, or the Google Authenticator mobile app.

  • Email: Check your email for the 8-digit myCGS verification code.

    Screenshot 7
  • Text: The 8-digit MFA code will be delivered to your device via text message. (Standard text messaging rates may apply.)
  • Google Authenticator: You may opt to receive your MFA code via the Google Authenticator app. This app assigns a 6-digit code that can be used to access myCGS.
    • Go the My Account section for instructions on how to set up Google Authenticator on your iOS or Android device.

Once you receive the verification code, enter it in the appropriate field and click "Submit." If you need a new code, you may click Regenerate Code to select an option (text, email, or Google Authenticator) to enter a new one.


The verification code you receive via text or email may be used repeatedly for up to 12 hours from the generation time of the code. If you log out of myCGS and, within 12 hours of the generation of the original MFA code, log back in, you will be directed to the "Welcome to myCGS" screen, where you may simply re-enter your original MFA verification code.

In the event your MFA verification code expires or cannot be located, you can always generate a new verification code that can be used for up to 12 hours by clicking the "Regenerate Code" link.

If using Google Authenticator, the 6-digit code changes every 30 seconds. Be sure to use the code that coincides with your myCGS account for which you are accessing.

myCGS Session Timeout

For security purposes, all myCGS sessions will automatically timeout after 15 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.

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.

      Screenshot 9
  • If you are the only Provider Administrator 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.) Refer to 30-Day Lock-Out Notification Timer below for additional information.
  • Provider Administrators must register for myCGS again. You will receive a new myCGS User ID. You must also add any Provider Users to myCGS as new users, as they will be deactivated as well.
    • If there is another Provider Administrator in your organization, contact that person. The active Provider Administrator must add you as a new user with a new myCGS User ID. The Provider Administrator may also allow you access as an additional Provider Administrator.

CGS encourages more than one Provider Administrator.

30-Day Lock-Out Notification Timer

So that all users know when their accounts are in jeopardy of being terminated due to inactivity of the Provider Administrator, myCGS will display a timer to notify you of this. The initial notification timer will display on day 30. The notification timer appears daily starting at day 15 through day 1.

When you see this notification, immediately to alert your Provider Administrator to log into myCGS to avoid terminating the entire account.
