# Healthcare Exclusion Lookup

> Free remote MCP server (Claude connector) published by Starry Night. It screens people and businesses against a mirror of the HHS-OIG List of Excluded Individuals/Entities (LEIE), the list of those excluded from Medicare, Medicaid and other federal health care programs, by name (fuzzy matching) or NPI. Public U.S. government data; no sign-in. Not affiliated with HHS-OIG or any government agency. Results are name-based possible matches for human review, to be confirmed on OIG's official search (https://exclusions.oig.hhs.gov/); not legal advice.

## Tools (all read-only)

- screen_exclusion: one person or business name; tolerant of word order, middle names and initials, suffixes, credentials, punctuation, hyphenated surnames, nicknames and one-letter typos. Returns ranked possible matches with score, name, category, specialty, city, state, ZIP, NPI, exclusion type and meaning, exclusion date and waiver, or no match at the threshold. Inputs: name, type, state, npi, dob (YYYY-MM-DD; only reported as matches or not, never returned), min_score (default 0.85), limit, detail.
- screen_exclusions: up to 25 names per call (strings or objects with state, npi, dob), best match per name.
- check_npi: a 10-digit NPI against the LEIE NPI field (most LEIE records have no NPI, so screen the name too).
- exclusion_list_status: OIG update date, data month, file timestamp and hash, record counts, last build and check times.
