OIG LEIE Exclusion Data

New exclusion additions by year

Federal healthcare exclusions added to the OIG LEIE per calendar year, 2012–2025. Partial-year data (2026, in-year snapshot) is excluded to avoid a misleading declining tail. Reporting lag means recent enforcement actions may land in subsequent annual cohorts.

What is the OIG LEIE?

The Office of Inspector General List of Excluded Individuals/Entities is the definitive federal registry of providers and entities barred from participation in Medicare, Medicaid, and other federal healthcare programs under Sections 1128 and 1128A of the Social Security Act. It covers both mandatory exclusions — program-related convictions, patient abuse, healthcare-fraud felonies carrying a minimum five-year exclusion period — and permissive exclusions tied to license actions, kickbacks, and claims-based enforcement.

As of Fonteum's most recent ingestion, the LEIE carries 68,055+ active exclusions — a mix of individual practitioners (physicians, nurses, pharmacists) and entities (billing companies, DME suppliers, laboratories). The OIG publishes an UPDATED.csv each month; Fonteum ingests it on the third business day of the month and timestamps each ingestion with a snapshot date, source-file SHA-256 hash, and methodology version string.

Federal scope only. The LEIE does not consolidate state Medicaid exclusion lists — 42 states maintain separate registries with documented latency to federal listing. Fonteum surfaces this gap explicitly in the provenance rail on every exclusion record rather than conflating federal and state-level status.

Who uses OIG exclusion screening data

Frequently asked questions

What is the OIG LEIE and how often is it updated?

The OIG List of Excluded Individuals/Entities (LEIE) is the federal registry of healthcare providers and entities barred from billing Medicare, Medicaid, and other federal health programs. It is published by the U.S. Department of Health and Human Services Office of Inspector General and updated monthly. Fonteum ingests the UPDATED.csv monthly and timestamps each ingestion with a snapshot date and source-file hash.

How does Fonteum's LEIE data differ from downloading the raw OIG CSV?

The raw OIG UPDATED.csv is a flat file with no provenance metadata, no API layer, and no cross-reference to NPI or CMS provider records. Fonteum adds a fourteen-field source attribution (source, source_url, dataset_id, snapshot, methodology, last_checked, confidence, availability, pipeline_version, DOI, license, coverage_start, coverage_end, SLSA_url), NPI cross-match for records that carry one, FHIR R4 Practitioner-compatible JSON output, and bulk export via the $export endpoint. Every row is traceable to the specific OIG file that produced it.

Does Fonteum's LEIE data cover state Medicaid exclusion lists?

No — and Fonteum says so explicitly in the methodology. The OIG LEIE covers federal healthcare program exclusions only. 42 states maintain separate Medicaid exclusion lists with documented latency to the federal LEIE. SAM.gov procurement debarment is a separate dataset with overlapping but non-identical scope. Fonteum surfaces these gaps in the provenance rail rather than papering over them.

Can I use Fonteum's LEIE data for automated exclusion screening workflows?

Yes. Fonteum exposes the exclusion dataset via a REST API and FHIR R4 $export endpoint suitable for integration with credentialing platforms, HR systems, and compliance automation tools. The API returns exclusion status, exclusion type (mandatory 1128a vs permissive 1128b), basis, and NPI where available. Rate limits and SLA terms are detailed in the data-platform documentation.

Is the OIG LEIE data free to use commercially?

The underlying OIG LEIE data is published under U.S. Government Works and is not subject to copyright. Fonteum's provenance layer, cross-references, and API infrastructure carry their own terms. Fonteum's standard data-platform agreement covers commercial use of the enriched dataset; the methodology documentation describes exactly which fields originate from the government source vs Fonteum-added enrichment.

Methodology

Records come directly from the monthly OIG LEIE file — not from a screening aggregator. The pipeline runs in five stages: (1) source acquisition from oig.hhs.gov, (2) entity resolution on the NPI where present, (3) authority mapping of each exclusion_type to its §1128 statute, (4) quality checks against the published OIG record count, and (5) chain attestation. Each value is asserted and chained, then labeled with its provenance — attested, signed, or provenance-tracked — never with unbacked trust language.

These four headline fields begin the 14-tuple provenance chain. The full contract is on the data sources reference.
