OIG LEIE (List of Excluded Individuals/Entities)

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.

Research and data questions this source supports.

• 01Screen a provider roster for active OIG exclusions before credentialing or contracting — federal law prohibits payment to excluded providers.
• 02Build a compliance automation that flags newly excluded providers on a monthly basis when OIG publishes the UPDATED.csv.
• 03Power a sanctions disclosure surface that shows exclusion type, exclusion date, and reinstatement date with source attribution.
• 04Cross-reference a claims dataset against LEIE to flag payments made to excluded providers for audit purposes.
• 05Provide M&A diligence with a pre-close OIG exclusion screen on all named providers in the target practice.

Dataset size: 68,055 exclusion records (May 2026 snapshot)

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.

What 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.

Authority, license, refresh cadence.

What the source allows.

U.S. government public-domain works (17 U.S.C. § 105). OIG publishes the LEIE UPDATED.csv at oig.hhs.gov/exclusions/downloadables/ with explicit redistribution rights. Fonteum mirrors the source bytes (SHA-256 attested) monthly.

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).

Common questions about OIG LEIE.

What is the OIG LEIE and why does it matter for healthcare compliance?

The OIG List of Excluded Individuals/Entities (LEIE) is the federal government's authoritative list of healthcare providers and organizations excluded from participation in Medicare, Medicaid, and other federal healthcare programs. Under the Social Security Act, healthcare organizations that employ or contract with an excluded individual may be liable for civil monetary penalties. Monthly screening against the LEIE is a compliance best practice and a condition of many Medicare/Medicaid contracts.

How do I download the OIG LEIE exclusions list?

OIG publishes the LEIE as a monthly CSV at oig.hhs.gov/exclusions/downloadables/. The UPDATED.csv file is the incremental monthly file; the EXCLUSIONS.csv file is the full current list. Both are U.S. government public-domain data with no redistribution restriction beyond attribution.

How often does the OIG LEIE update?

OIG adds new exclusions and processes reinstatements each month, publishing updated files around the first business day of the month. Fonteum's Inngest cron pulls the monthly UPDATED.csv within 24 hours of publication and attests the SHA-256 hash to the provenance chain.

What types of exclusions does the LEIE cover?

The LEIE carries mandatory exclusions under §1128(a) of the Social Security Act (conviction for fraud, patient abuse, or controlled-substance offenses) and permissive exclusions under §1128(b) (licensing-board actions, unnecessary services, failure to disclose information, and other categories). The exclusion_type field in the dataset identifies the statutory basis for each exclusion.

What is the difference between an OIG exclusion and a state Medicaid exclusion?

The LEIE tracks federal exclusions that apply to Medicare, Medicaid, and all other federal healthcare programs nationally. Each state also maintains its own Medicaid exclusion list, which may contain additional individuals excluded only at the state level. For full compliance coverage, organizations typically screen both the federal LEIE and the relevant state Medicaid exclusion lists.
