Healthcare Exclusion Lookup

Validates a 10-digit National Provider Identifier (check digit) and looks it up in the NPI field of the LEIE mirror. Returns the excluded record(s) that carry it, or a not-on-list result. Most LEIE records have no NPI, so a not-on-list result does not show that a provider is not excluded.

Returns the version of the mirrored LEIE: OIG's last update date and the month the data runs through, the source file's timestamp, size and hash, record counts (individuals, entities, with NPI), the latest monthly supplement, and when the mirror was last built and last checked for updates.

Screens one person or business name against a mirrored copy of the HHS-OIG List of Excluded Individuals/Entities (LEIE), the list of people and businesses excluded from Medicare, Medicaid and other federal health care programs. Person names match in any word order, with or without middle names or initials, suffixes (Jr, Sr, III), credentials (MD, RN), punctuation, hyphenated surnames, common nicknames and one-letter typos; business names match without company-form words (LLC, Inc, PC) and with abbreviations and small typos. Returns ranked possible matches with score, name, general category and specialty, city, state, ZIP, NPI when present, exclusion type with its meaning, exclusion date and any waiver, or a no-match result at the threshold, plus the list's as-of date. Optional state, NPI and date-of-birth filters narrow common names.

Screens up to 25 person or business names in one call against the same LEIE mirror as screen_exclusion and returns only the best possible match per name (or no match at the threshold) in compact form, with a summary count. When a state, npi or dob filter leaves out every record at or above the threshold, the result for that entry is no_match_after_filters and it shows the best record the filter left out. Each entry can be a name string or an object with name and optional state, npi and dob (YYYY-MM-DD).
