+# 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/](https://tensorust.com/datasets/cms-revalidation-due/)**.
