How to Search the OIG LEIE Database
By Keelstar Team · Updated July 11, 2026
The short answer
The OIG LEIE database is the authoritative federal source for healthcare program exclusions. Search using each party's legal name first, then repeat with known aliases, DBAs, and maiden names. OIG matching is name-based — partial or misspelled names miss hits. Record the search date, the list download date shown on the site, every name variant checked, and the result. A single clear search at onboarding is not sufficient; exclusions are added continuously, so tie each search to your re-screening schedule and retain evidence auditors can reconstruct months later.
Where to access the LEIE
The U.S. Department of Health and Human Services Office of Inspector General hosts the LEIE on its public website. You can run individual name searches or download the full exclusion file for offline or batch matching. Bookmark the official OIG URL — not third-party mirrors — so your audit trail references the correct source.
Names and identifiers to search
Start with the legal name on tax and contract documents. Then search known DBAs, former names, and common misspellings. For individuals, include suffixes and maiden names when applicable. For entities, search the registered business name and any trade names. When available, cross-reference NPI, date of birth, or address against a potential match to resolve false positives.
- Legal name from W-9 or contract
- DBAs and trade names
- Former or maiden names for individuals
- Key owners and officers for small entities when policy requires
Individual search vs. full list download
Individual online searches work for onboarding one vendor or employee at a time. Downloading the full LEIE file supports batch screening across your vendor master or payroll roster. Either approach is valid — what matters is consistent methodology, dated results, and retained evidence. Many compliance teams combine both: download for scheduled re-screens, individual search for ad hoc checks.
Common search mistakes
Teams miss exclusions when they search nicknames instead of legal names, skip alias variations, or assume a prior clear result still holds. Another frequent gap: screening the company name but not individual owners of sole proprietorships or small LLCs who perform billable work. Document every name variant you checked, not just the final disposition.
What to record for each search
Each LEIE search should produce an audit-ready record: party screened, date and time of search, LEIE list version or download date, names searched, result (clear, potential match, confirmed match), and reviewer identity. Manual screenshots in email fail at scale — use a structured log or screening workflow that captures these fields automatically.
Integrate LEIE search into your workflow
Do not treat OIG database search as a one-off compliance task. Embed it in vendor onboarding, contractor credentialing, and employee hire checklists. Block payment or system access until the initial search completes. Schedule recurring re-searches so exclusions added after onboarding are caught before claims or payments flow.
Frequently asked questions
- Is the OIG LEIE search free?
- Yes. The OIG publishes the LEIE online at no cost. You can search individual names or download the full list for batch screening. Many organizations supplement manual searches with automated tools that log results.
- Should I search by first name only?
- No. Search the full legal name as it appears on the W-9, contract, or credentialing file. Repeat with aliases and variations. First-name-only searches produce excessive false positives and miss entity matches.
- How often is the LEIE updated?
- OIG updates the LEIE monthly, but exclusions can be effective before the list reflects them. Search at onboarding and re-screen on your defined schedule — monthly or quarterly is common for healthcare providers.
- Can I rely on a third-party vendor's OIG check?
- You can accept vendor attestation as a starting point, but CMS and payer auditors typically expect your organization to maintain its own dated search records. Verify rather than assume.
