Medicare Revalidation Due List: free sample (Tensorust LLC)

45,356 Medicare provider organizations whose enrollment revalidation is due by May 2027. Miss it and Medicare billing stops.

Headline: CMS publishes when every Medicare-enrolled provider must revalidate its enrollment; a provider that misses the date can have billing privileges deactivated.

This repository is a free teaser, not the dataset. It holds 25 example rows and a summary table with no names in it. The full file has 45,356 rows and is sold by Tensorust LLC: https://tensorust.com/datasets/cms-revalidation-due/.

Method and limits

Load the CMS revalidation base file, keep enrollment IDs starting with O (organizations), use the adjusted due date when present, compute days until due from Nov 6, 2026, and bucket.

Not a list of deactivated providers. A passed date in the list can mean CMS has not yet posted a completed revalidation. Contains no contact details and no individual clinicians.
