OIG LEIE Exclusion Search

Search

68,000+Source: https://oig.hhs.gov/exclusions/exclusions_list.asp · Dataset: oig-leie/v1 · Snapshot: 2026-05-01
federal exclusion records from the HHS Office of Inspector General's List of Excluded Individuals/Entities (LEIE). Monthly refresh. Source-provenanced to the official OIG download. Free, no signup.

For informational use only. Always verify exclusion status directly at oig.hhs.gov/exclusions/ before making credentialing, contracting, or employment decisions. Fonteum's data reflects the most recent monthly ingest and may lag the live OIG list by up to 30 days.

Pinned, audit-traceable

The OIG LEIE covers individuals and entities excluded under 42 U.S.C. §1320a-7 and related statutes. Each record includes exclusion type, effective date, reinstatement date (if applicable), specialty, address, and NPI where reported by OIG. Fonteum adds fourteen-field provenance — source identifier, release date, methodology version, ingest timestamp — so every record is traceable to its origin.

Frequently asked questions

What does an OIG exclusion mean?
An OIG exclusion bars an individual or entity from participating in Medicare, Medicaid, and all federal healthcare programs. Employers and contractors who hire excluded individuals risk civil monetary penalties. The exclusion remains in effect until reinstated by OIG.
How current is this data?
Fonteum re-ingests the OIG LEIE monthly from oig.hhs.gov. The ingest timestamp is shown on every result record so you know exactly how fresh the data is. For compliance decisions, confirm against the official OIG exclusion list.
Can I screen by NPI?
Yes — use the NPI tab and enter the 10-digit National Provider Identifier. Not all OIG exclusion records include an NPI (OIG reports what the excluded party filed); name search covers records that lack one.
How do I get bulk LEIE data for automated screening?
Fonteum’s audit-pack export provides bulk access to the full oig_leie_exclusions table with field-level provenance. The data-platform API exposes the same data via REST. See the links below.
