The Centers for Medicare & Medicaid Services (CMS) has recently released information about an important Physician Quality Reporting System (PQRS) system update. The update will go into effect on Monday, July 13.

As part of the update, the Individuals Authorized Access to CMS Computer Services (IACS) system will be retired and current IACS user accounts will transition to an existing CMS system called Enterprise Identity Management (EIDM).The EIDM system provides a way for business partners to apply for, obtain approval of, and receive a single user ID for accessing multiple CMS applications.

Important information about the transition is below. For more information, access the CMS EIDM User Guide or contact the QualityNet Help Desk at 866-288-8912.

  • Existing PQRS IACS users, their data, and their roles will move to EIDM and will be accessible from the “CMS Secure Portal” portion of the CMS Enterprise Portal at
  • Users should ensure that their IACS account is active and current, and that they’re able to log in. Users should reset their IACS password now if they think their password might expire before 5 p.m. EDT, July 3.
  • Users should not make changes to their user profile or submit a request of any type that cannot be approved prior to 5 p.m. EDT, July 3.
  • Users should not register for a new account in EIDM prior to the system update on July 13. This will only complicate moving their IACS account to the new EIDM system.
  • If you not have an IACS account, visit the CMS Enterprise Portal at and click “New User Registration” under “Login to CMS Secure Portal.” NOTE: New IACS registration requests will be cut off as of 5 p.m. EDT on Friday, July 3. After that point, new users will need to wait until the EIDM system launches on Monday, July 13, to request a new account.
  • For additional information, reference the EIDM Quick Reference Guides, which will be available in July on the Physician and Other Health Care Professionals Quality Reporting Portal.
