OIG LEIEOIG LEIE (List of Excluded Individuals/Entities)
U.S. Department of Health and Human Services Office of Inspector General · Tier-2 · profile-enrichment (renders on matched profiles)
The OIG List of Excluded Individuals/Entities is the authoritative federal registry of healthcare providers and organizations excluded from participation in Medicare, Medicaid, and all federal healthcare programs under §1128 and §1156 of the Social Security Act. Approximately 75,000+ active exclusions as of 2026.
How this source shows up on Fonteum.
Exclusion status check on provider profiles: any NPI in oig_leie_exclusions surfaces a compliance flag on the profile with exclusion type, date, and reinstatement date where applicable. Powers the brand-hub /sanctions surface.
What this source does NOT mean
An OIG exclusion is a formal enforcement action by the federal government — not a quality rating, clinical outcome measure, or editorial opinion by Fonteum. Reinstatement applications and appeals are processed by OIG; Fonteum reflects only the publicly published exclusion record as of the snapshot date.
Per-field display contract.
Every field below has a `display_allowed` flag in the §94 provenance schema. Write-locked fields are captured to provenance for audit but never rendered on profile pages.

1 fieldWhat we can’t infer from this source.
- Snapshot-based: exclusions added or reinstated after the monthly snapshot date will not appear until the next pull.
- NPI is not present for all exclusion records — entity records and older individual records may lack an NPI, limiting provider-profile cross-reference.
- An exclusion record reflects the enforcement action as published by OIG; Fonteum does not verify the underlying facts, adjudication status, or appeal outcome.
- Reinstated providers retain a historical exclusion row; Fonteum surfaces reinstatement_date when present but does not remove historical rows.

What a single field looks like in the graph.
A worked example. Every field surfaced from this source carries this shape of provenance line — source · last checked · display rule · confidence (when applicable).

Compliance posture
We don’t sell ranking and don’t accept payment to move a provider up the list. For final hire decisions, verify licensing, insurance, and references directly with the applicable licensing or credentialing body.
No bulk-licensing source family is currently ingested for this vertical. Hire-time checking still routes through the body named above.
