LEIE: Definition and Healthcare Context

Full name: List of Excluded Individuals/Entities

The List of Excluded Individuals/Entities (LEIE) is a database maintained by the HHS Office of Inspector General (OIG) of individuals and entities barred from participation in federal health care programs. OIG publishes a monthly bulk CSV. Fonteum's loaded release was dated May 8, 2026 when checked July 12, so consequential status must be confirmed at OIG.

Last updated: 2026-07-11Reviewed by: Dr. Jennifer Montecillo, MD — Gullas College of Medicine, 2019. Non-practicing medical reviewer.

How it’s used

  • OIG LEIE (oig-leie): Fonteum's loaded bulk release was dated May 8, 2026 when checked July 12; OIG publishes newer files on its own schedule. NPI matching is available only where the record supplies an NPI.
  • CMS NPPES NPI Registry: NPPES records are cross-referenced against the LEIE to flag excluded providers in Fonteum's provider data graph.
  • CMS PECOS Medicare Provider Enrollment: PECOS enrollment revocations often follow OIG LEIE exclusion actions.

Reproducible by design

Published figures name their source and date.

Source and date

Published research identifies its government file and observation date. Source-file SHA-256 coverage is disclosed separately; facts do not currently link deterministically to signatures.

Reproducible SQL

Each study ships the exact query behind its figures, run against the same dated copy of the federal file we used. Re-run it yourself.

Daily observations

The platform records table row counts daily. Those observations detect local drift; they do not imply that an upstream publisher released or Fonteum ingested new data that day.
