The OIG exclusion list, formally the List of Excluded Individuals/Entities (LEIE), is the Office of Inspector General's public register of people and businesses barred from Medicare, Medicaid, and all other federal health care programs. As of the October 2026 file it names 84,093 excluded parties. Hiring or billing for an excluded party can trigger civil monetary penalties, which is why credentialing and compliance teams screen against this list every month.
Every exclusion cites an authority in the Social Security Act. The section tells you why the party was excluded, and whether OIG had a choice.
Convictions where the law requires OIG to exclude: program-related crimes, patient abuse or neglect, felony health care fraud, and felony controlled-substance convictions. Minimum five years.
Exclusions OIG may impose: license revocations (the single largest category), misdemeanor fraud, kickbacks, defaulted health-education loans, and more. Terms vary by authority.
Counts are exclusion entries on the October 2026 file. A party excluded more than once appears once per entry.
80,627 of the 84,093 parties are individuals; 3,466 are businesses (home health agencies, pharmacies, DME companies, and others). The most common role labels on the file, as OIG codes them:
By exclusion effective date on the current active file. Reinstated parties have already dropped off, so early years understate history.
Address state as filed with OIG. Every U.S. state appears on the list.
Only 10.6% of LEIE rows carry an NPI: many excluded parties (aides, business owners, entities, pre-NPI exclusions) never held one. An NPI check is definitive when it hits, but an NPI-only screen cannot see roughly 9 in 10 rows of the file. That is why OIG's own tool, and ours, search by name, with identity confirmed afterward.
OIG can waive an exclusion, for example for a sole community physician. A party with a §1128 waiver may be legally billing in the waived program or state. Any screen that shows an exclusion without its waiver is wrong in the way that hurts a real person, so our checker always renders the waiver line when OIG's file carries one.
OIG publishes the LEIE as a full replacement file every month, and reinstated parties simply drop off. So the honest claim is always dated: "not on the October 2026 file", never "never excluded" and never "reinstated". If a party you found last month is gone this month, that is the file doing its job.
Federal screening policy generally requires checking both the LEIE and the SAM.gov exclusion records (which cover government-wide debarments beyond health care). This page and our tool cover the LEIE only, and say so rather than pretend otherwise.
