Built on the authoritative federal record
The primary sources, named on every page.

The substrate, by the numbers
Fonteum mirrors the NY Office of the Medicaid Inspector General provider-exclusion list as a screening aid: 8,904 records, 2,271 (26%) carrying an NPI, of which 2,056 match a provider in our graph. Records are not a determination by Fonteum; reinstatements can lag — cross-check any record at the source.
Showing the 50 most-recent records that match a provider NPI in Fonteum’s graph (of 2,056matched). Select a name to open its provider profile, where the exclusion sits beside the provider’s other source-traced facts. Records without an NPI are counted in the totals above but are not individually listed.
