Federal Exclusion Screening

Check a person or organization against the HHS-OIG List of Excluded Individuals/Entities and SAM.gov federal exclusion records in one search. Every result states which source it came from, how current that source is, and exactly which identity fields matched.

Free. No account required.

NPISignal never asks for a Social Security number or an employer identification number, and does not accept a date of birth on a public search — a query string ends up in browser history and server logs, and a third party’s date of birth does not belong in either. Supplying an NPI or a state is what sharpens a public result. Monitored roster records can carry a date of birth, encrypted at rest.

Doing this for a whole team every month?

Upload your staff, provider or vendor roster once. NPISignal reruns the same screening when the source data changes and emails you only when something needs a look.

Screened September 20, 2026 using matching algorithm v1.0. NPISignal compares publicly published identity fields — name, date of birth where the source publishes one, NPI, location and specialty. It cannot verify identity using a Social Security number or an employer identification number, and does not attempt to: those verifications are available only through the issuing agency’s own process.

NPISignal is an independent service and is not affiliated with CMS, HHS-OIG, the General Services Administration, or the U.S. government. Automated matching produces both false positives and false negatives. NPISignal does not determine, certify or guarantee regulatory compliance; responsibility for verification and for any employment or contracting decision remains with your organization.
