OIG LEIE Exclusion Data
Fonteum ingests the OIG List of Excluded Individuals/Entities — every active federal healthcare exclusion — and attaches per-field provenance, NPI cross-reference, and FHIR R4 bulk export. Compliance teams and credentialing platforms use this layer to automate exclusion screening without rebuilding the parse-and-store pipeline from scratch.
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.
What Fonteum adds to the raw source
The raw OIG CSV is a flat file: no API, no schema versioning, no NPI cross-reference, no audit trail. Fonteum transforms it into a structured, versioned, provenance-attached dataset:
- Fourteen-field source attribution on every row: source, source_url, dataset_id, snapshot, methodology, last_checked, confidence, availability, pipeline_version, DOI, license, coverage_start, coverage_end, SLSA_url.
- NPI cross-match — exclusion records that carry a National Provider Identifier are linked to the CMS provider record, enabling join-on-NPI queries across the full provider data graph.
- FHIR R4 Practitioner output — exclusion status surfaces as a meta.security tag on Practitioner resources via the /api/fhir/Practitioner endpoint, compatible with Epic and Cerner integration patterns.
- Bulk $export — NDJSON over the HL7 FHIR R4 Bulk Data Access specification, signed with SMART Backend Services, suitable for warehouse ingestion without per-record polling.
- Monthly diff feed — additions, removals, and reinstatements highlighted between consecutive snapshots so downstream systems only process changed records, not the full 68K corpus.
Who uses OIG exclusion screening data
Monthly exclusion screening against provider networks is a CMS condition of participation. Fonteum's diff feed reduces the screening run from a full-corpus comparison to a changed-records-only check, cutting processing time and audit documentation overhead.
Primary-source exclusion screening for physician and allied-health credentialing requires a LEIE check as a mandatory step. Fonteum's NPI-keyed API eliminates the manual CSV parse and delivers exclusion status as a structured JSON field with source traceability.
Medical staff offices managing hundreds of privileged providers need an exclusion monitoring pipeline that logs each check with a timestamp and source citation — required documentation for CMS audits. Fonteum's audit-pack export packages this evidence trail automatically.

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.
