Search the OIG exclusion list (LEIE)

Check any provider or entity against the OIG LEIE — the federal exclusion list — free, every match traced to its source. Need SAM.gov and state Medicaid lists too? Upload a roster for one signed screen.

Fonteum mirrors

68,000+Source: OIG LEIE · As of 2026-05-01
federal exclusion records from the HHS Office of Inspector General's List of Excluded Individuals/Entities. Monthly refresh, source-provenanced to the official OIG download. No signup.

For informational use only. Always confirm exclusion status directly at oig.hhs.gov/exclusions/ before making credentialing, contracting, or employment decisions. Fonteum's data reflects the most recent monthly ingest and may lag the live OIG list by up to 30 days.

Pinned, audit-traceable

The OIG LEIE covers individuals and entities excluded under 42 U.S.C. §1320a-7 and related statutes. Each record includes exclusion type, effective date, reinstatement date (if applicable), specialty, address, and NPI where reported by OIG. Fonteum adds fourteen-field provenance — source identifier, release date, methodology version, ingest timestamp — so every record is traceable to its origin.

What the OIG exclusion list is

The List of Excluded Individuals/Entities is the federal government's record of providers who may not be paid by Medicare, Medicaid, or any federal healthcare program. An exclusion means the program will not pay for anything the excluded party furnishes, orders, or prescribes — directly or through an employer. The HHS Office of Inspector General maintains the list and posts a fresh download each month.

Exclusions split into two kinds. Individual exclusions name a person — a physician, nurse, pharmacist, or owner — usually after a conviction, license action, or controlled-substance offense. Entity exclusions name an organization — a clinic, lab, supplier, or staffing firm. The search above runs across both: use the individual-name or NPI tab for people, and the organization tab for businesses.

Who must screen the LEIE — and how often

Any organization that bills a federal healthcare program is expected to screen its workforce against the OIG exclusion list. OIG guidance points employers to screen every employee and contractor before hire and monthly after that, because a provider can be added to the list at any point in the month and the obligation is ongoing.

The cost of a missed exclusion is steep. Under Section 1128A of the Social Security Act, the OIG can impose civil monetary penalties of up to $24,947 per item or service furnished by an excluded individual, plus treble damages and repayment to the program. Because the penalty accrues per claim, a single excluded hire can generate large exposure between screening cycles — which is why monthly screening is the recommended cadence. Read the full exclusion-screening process for the step-by-step.

One pass, every exclusion list

A LEIE-only check misses providers who are excluded somewhere other than the federal list. Fonteum's compromised-anywhere screen runs a name or NPI against the OIG LEIE, the GSA SAM.gov debarment registry, and every state Medicaid exclusion list it mirrors — plus OIG Corporate Integrity Agreement and CMS civil-money-penalty flags — in one pass. A single-list lookup cannot do that.

Each match returns signed to its source: the source file, snapshot date, and methodology version that produced it, packaged as an Ed25519-signed, hash-chained attestation you can hand an auditor. Upload a roster and Fonteum screens every name and NPI against all of it — public data only, no PHI, no sales call to get the first screen.

Frequently asked questions

What is the OIG exclusion list (LEIE)?
The OIG List of Excluded Individuals/Entities (LEIE) is the federal database of providers barred from Medicare, Medicaid, and all federal healthcare programs. The HHS Office of Inspector General publishes it and refreshes it monthly. Exclusions follow convictions for healthcare fraud, patient abuse or neglect, license revocation, or controlled-substance offenses.
Who has to screen the OIG exclusion list?
Any organization that bills Medicare or Medicaid — hospitals, health systems, nursing homes, group practices, pharmacies, health plans, and staffing firms. OIG guidance directs employers to screen every employee and contractor against the LEIE before hire and monthly thereafter, because a party can be excluded at any point in the month.
What does it cost to employ an excluded provider?
Under Section 1128A of the Social Security Act, the OIG can impose civil monetary penalties of up to $24,947 per item or service furnished by an excluded individual, plus treble damages and repayment to the federal program. The penalty accrues per claim, so one excluded hire can create large exposure between screening cycles.
How current is Fonteum's LEIE data?
Fonteum re-ingests the OIG LEIE monthly from oig.hhs.gov, and the ingest timestamp shows on every result. For a credentialing, contracting, or employment decision, confirm the match against the official OIG exclusion database before acting.
Can I search the exclusion list by NPI?
Yes. Use the NPI tab and enter the 10-digit National Provider Identifier. Not every LEIE record carries an NPI — OIG records what the excluded party reported — so individual and organization name search covers the records that lack one.
Does this also cover SAM.gov and state Medicaid exclusions?
This search covers the OIG LEIE. To check a roster against SAM.gov debarments and state Medicaid exclusion lists too — the compromised-anywhere screen — upload your roster for a free signed attestation at pilot intake.
