Important changes to the
CMS Enterprise Identity Management System

This change is planned to occur February 19, 2021 with the first date end users will encounter IDM as Monday, February 22. 2021. During the maintenance window, access to the Preclusion List application and the files may not be available. Additionally, please do not add or remove any roles prior to the Go Live date of Monday, February 22, 2021.
For more details, please read the Preclusion List EIDM to IDM Migration Help Guide (PDF).
Who is on the list?
Individuals or entities who meet the following criteria:
Are currently revoked from Medicare, are under an active reenrollment bar, and CMS has determined that the underlying conduct that led to the revocation is detrimental to the best interests of the Medicare program.
Have engaged in behavior for which CMS could have revoked the individual or entity to the extent applicable if they had been enrolled in Medicare, and CMS determines that the underlying conduct that would have led to the revocation is detrimental to the best interests of the Medicare Program.
Have been convicted of a felony under federal or state law within the previous 10 years that CMS deems detrimental to the best interests of the Medicare program.
You will receive an email and letter from CMS/Medicare Administrative Contractors (MAC) in advance of your inclusion on the Preclusion List.

The letter will contain the reason you are precluded, the effective date of your preclusion, and your applicable rights to appeal.
