Healthcare Exclusion Lookup
Screen people and businesses against the HHS-OIG exclusion list (LEIE) by name or NPI, with fuzzy matching, state and date-of-birth filters, and the list's as-of date. Remote server at https://exclusions.trystarrynightops.com/mcp, no sign-in. Possible matches need human review against OIG's own search.

Screen staff and vendors against the OIG exclusion list in Claude
A free connector that lets Claude check people and businesses against a mirror of the HHS-OIG List of Excluded Individuals/Entities (LEIE): the people and companies excluded from Medicare, Medicaid and other federal health care programs. Healthcare employers, practices, pharmacies, staffing agencies and billing companies screen employees, contractors and vendors against it; OIG advises routine checks, and employing or contracting with an excluded party can lead to civil monetary penalties.
Not affiliated with HHS-OIG or any government agency. Results are name-based possible matches for a person to review. Confirm any match on OIG's official online search, which verifies identity with an SSN or EIN. A no-match is not a clearance. Not legal advice.
Screening a whole list? Use the screening record page
Paste or upload up to 500 staff, contractor or vendor names (with optional state, NPI and date of birth) and screen them all at once in your browser against the LEIE and 14 state Medicaid exclusion lists (NY, CA, TX, MI, GA, MD, LA, AR, KY, NC, WA, IA, SC, AL). Results show on screen, and the page builds a dated PDF record of the run with the version of each list, the matching method and every result, ready for a person to review and file.

Tools
screen_exclusion
Screens one person or business name. Person names match in any word order, with or without middle names or initials, suffixes (Jr, Sr, III), credentials (MD, RN, DO), punctuation and hyphenated surnames (Smith-Jones is found as Smith or Jones), common nicknames (Bill / William) and one-letter typos. Names listed with only a first initial are found by that initial or by the middle name the person goes by. Business names match without company-form words (LLC, Inc, PC, PLLC), with common abbreviations (Ctr, Svcs, Med) and small typos. Returns ranked possible matches with score, name, general category, specialty, city, state, ZIP, NPI when on file, exclusion type with a plain-English meaning of the legal authority, exclusion date and any waiver.
Inputs: name (required), type (individual or entity), state, npi, dob (YYYY-MM-DD), min_score (default 0.85), limit (default 5), detail (summary or full). The state, NPI and date-of-birth filters leave out records that differ and say how many; records with nothing on file for that field are kept.
{"name": "Jane Q. Doe", "state": "OH", "dob": "1980-02-01"}
screen_exclusions
Screens up to 25 names in one call and returns the best possible match per name in compact form, with a summary count. Each entry is a name or an object with its own state, NPI and date of birth. When a filter leaves out every record at or above the threshold, the entry reads no_match_after_filters and shows the best record left out, so a filtered-out exact name is never reported as a plain no-match.
{"names": ["Jane Doe", {"name": "John Q. Public", "state": "TX", "dob": "1970-01-31"}, "Acme Home Health LLC"]}
check_npi
Checks a 10-digit NPI (with its check digit) against the NPI field of the LEIE. Only about 10.7% of LEIE records include an NPI, so an NPI that is not on the list does not clear anyone: screen the name too.
{"npi": "1234567893"}
exclusion_list_status
Shows OIG's last update date, the month the data runs through, the source file's timestamp and hash, record counts, the latest monthly supplement, and when the mirror was last built and checked.
{}
Scores run from 0 to 1. A score of 1 means the first and last names (or the business name) are the same after normalization; 0.9 to 0.96 usually means a nickname or a one-letter difference; below 0.85 (hidden by default) are weaker candidates such as two different common names one letter apart (Gary / Mary) or a different middle name. Common names match several records: the LEIE lists, for example, about a dozen people named Mary Johnson. Use the state, NPI and date-of-birth filters to narrow them, then verify on OIG's site.
Data sources and freshness
All data is public data from the U.S. Department of Health and Human Services, Office of Inspector General. This service keeps its own mirror and answers from it; your queries are never sent to OIG or anyone else.
- LEIE Database & Supplement Downloads (HHS-OIG): the full database file UPDATED.csv and the monthly exclusion and reinstatement supplements.
- LEIE Online Search (HHS-OIG): the official search, with SSN and EIN verification.
- Exclusion authorities and waivers (HHS-OIG): the meaning of each exclusion type and the scope of waivers.
For the screening record page only (not the connector's tools), the service also keeps copies of these public state Medicaid exclusion lists, each downloaded from the state agency's own published file and checked for updates at each update run:

Not covered: Florida, Illinois, Pennsylvania, New Jersey, Ohio, Massachusetts and the other states not listed, and the SAM.gov exclusions. From state files the mirror keeps names, business names, provider type, license, NPI, city, state and the action and its date; it never keeps dates of birth, Social Security numbers, street addresses or owner names (ownership columns, or owner notes written next to a listed business), even where a file includes them.
The full LEIE file lists every exclusion currently in effect; reinstated people and businesses are removed from it. The mirror is checked for updates at each update run and rebuilt when the file changes. Current state:
| Item | Value |
|---|---|
| OIG last update | 2026-11-10 (actions through 2026-10) |
| Source file timestamp | 2026-11-10 10:18 UTC |
| Records | 84,224 (80,678 individuals, 3,546 businesses; 9,023 with an NPI) |
| Latest monthly supplement | 2026-10: 216 exclusions, 85 reinstatements |
| Mirror built | 2026-11-10 11:33 UTC (version d32868b3e395) |
| Last checked for updates | 2026-11-11 23:36 UTC |
Privacy in short
Names, NPIs and dates of birth you screen are processed in memory and are not stored or logged. A date of birth is compared through a keyed hash, so the service never holds or shows the date on file. Street addresses from the LEIE are not part of the mirror. Details in the privacy policy.
Limitations
- The connector's tools search HHS-OIG's LEIE only. The screening record page also screens 14 state Medicaid lists (NY, CA, TX, MI, GA, MD, LA, AR, KY, NC, WA, IA, SC, AL); other states' lists and the SAM.gov exclusions are not included and may also apply to you.
- Name matching. The LEIE holds the name known to OIG at the time of exclusion, so check former names (maiden or previous married names) as well. A possible match must be verified on OIG's online search with an SSN or EIN.
- About 10.7% of records include an NPI. Most records include a date of birth, but not all.
- Addresses are as of the exclusion; people and businesses move, so a state filter can hide a true match.
- Business names in the source are limited to 30 characters and often abbreviated; longer names may be cut off.
- The mirror follows OIG's monthly file and can lag OIG's online search, which OIG may update between files.

Questions
Is this the official OIG exclusion search?
No. Healthcare Exclusion Lookup is an independent tool that searches a mirror of OIG's public LEIE download. Not affiliated with HHS-OIG or any government agency. OIG's official online search is at https://exclusions.oig.hhs.gov/; it can verify a match with a Social Security Number or Employer Identification Number, which the public download does not contain.
Does a "no match" clear a person or business?
No. A name search can miss people listed under a former name (for example a maiden name), and the LEIE covers only HHS-OIG exclusions, not state Medicaid lists or the SAM.gov exclusions. The screening record page (/record) also screens 14 state Medicaid lists (NY, CA, TX, MI, GA, MD, LA, AR, KY, NC, WA, IA, SC, AL); other states' lists and SAM.gov are not covered. Treat every result as a starting point for review.
Does the connector search state Medicaid exclusion lists?
Not yet: the connector's tools search the HHS-OIG LEIE. The screening record page at https://exclusions.trystarrynightops.com/record screens a list of up to 500 names against the LEIE and 14 state Medicaid lists (NY, CA, TX, MI, GA, MD, LA, AR, KY, NC, WA, IA, SC, AL) and builds a dated PDF record.
How current is the data?
OIG replaces the full LEIE file monthly, generally by the middle of the month, with all actions through the prior month. This mirror is checked for updates at each update run and rebuilt when the file changes. The table on this page and the exclusion_list_status tool show OIG's update date, the month the data covers and when the mirror was last checked.
Is what I screen stored?
No. Names, NPIs and dates of birth you screen are processed in memory to answer the call and are not stored or logged. Only anonymous daily counts of tool calls are kept. See the privacy policy.
Why are dates of birth and street addresses not shown?
To limit personal data. The tool returns name, category, specialty, city, state, ZIP, NPI and the exclusion details. If you give a date of birth, it only says whether it matches the record, and it never shows the date on file.
