Revalidation

Federal regulations require state Medicaid agencies to revalidate the enrollment of all Medicaid providers once every five years (42 CFR Part 455). Instructions on when to revalidate and how to complete your revalidation can be found on this page.

Am I currently up for revalidation?

You will be notified by mail when you are selected for revalidation. No action is required until you receive the revalidation letter from HCA.

When selected for revalidation, a single letter is mailed to the group or facility being revalidated. Revalidation letters are not sent to individual providers working in a clinic.

The revalidation notice will be sent to the mailing address listed in ProviderOne. To ensure the revalidation notification reaches your office, please login to ProviderOne to confirm your mailing address is up-to-date.

If you need assistance logging in to ProviderOne, please contact ProviderOne Security.
