Matched on NPI alone. OIG asks that any match be confirmed by Social Security or Employer Identification Number, neither of which appears in the public file, so treat this as something to verify rather than something established. Verify at OIG. Our copy of the list is from 2026-09-15. Reinstated parties are removed from each new release, so a person cleared since then may still appear here.
