The OIG List of Excluded Individuals/Entities is the federal registry of individuals and entities excluded from participation in Medicare, Medicaid, and other federal healthcare programs under §1128 and §1156 of the Social Security Act. Fonteum's serving table held 68,055 rows from the May 8, 2026 source release when checked July 12, 2026.
How this source shows up on Fonteum.
Exclusion-source context on provider profiles when an OIG row publishes the same NPI, with exclusion type, date, and reinstatement date where available. Most LEIE rows do not publish an NPI, so absence of a match is not clearance. 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.
Research and data questions this source supports.
- Screen a provider roster for active OIG exclusions before credentialing or contracting — federal law prohibits payment to excluded providers.
- Build a compliance automation that flags newly excluded providers on a monthly basis when OIG publishes the UPDATED.csv.
- Power a sanctions disclosure surface that shows exclusion type, exclusion date, and reinstatement date with source attribution.
- Cross-reference a claims dataset against LEIE to flag payments made to excluded providers for audit purposes.
- Provide M&A diligence with a pre-close OIG exclusion screen on all named providers in the target practice.

1 fieldWhat we can’t infer from this source.
- Snapshot-based: the loaded source date observed July 12 was May 8, 2026. Later OIG additions or reinstatements may be absent; confirm against OIG before acting.
- 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 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's loaded source date was May 8, 2026 when checked July 12; no provenance fact currently links deterministically to a signature.

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 list of individuals and organizations excluded from participation in Medicare, Medicaid, and other federal healthcare programs. Under the Social Security Act, civil monetary penalties, assessments, and repayment can apply when federal programs are billed for items or services furnished by an excluded party. OIG advises checking the LEIE before employing or contracting and periodically afterward, and says monthly screening best minimizes potential liability; applicable program and contract rules can differ.
- 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 captures and attests the monthly artifact on its scheduled run. A screening refresh is not complete until that exact artifact is projected into the serving table and reconciled by count and hash; until then, negative screens are indeterminate.
- 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.
