Why NPISignal flagged this

The NPI on both records is identical

The exclusion record carries the same NPI. This is the strongest signal available in the public data, and still warrants confirmation with the source before any action is taken.

Screened: Not checked

This is an NPI-based check only. NPISignal does not publish name-based exclusion matches on a provider profile. A shared or similar name is a lead that requires human review, not an identification, and this page is not the place to make one. Run a name-based screening below to see potential matches with the reasons for each.

This reflects only the records NPISignal currently holds and the identity information supplied. It is not a verification of eligibility, licensure, or compliance. Verify decisions that matter against the authoritative source.

Run a name-based screening

Searches OIG LEIE and SAM.gov by name and reviews every potential match.
