Data source

HHS Office of Inspector General — List of Excluded Individuals/Entities (LEIE), which OIG publishes as a CSV for loading into your own system:

US federal public domain. 83,782 exclusions as loaded — 80,355 individuals and 3,427 businesses.

This names real people — read this before using it

A false positive here accuses somebody of healthcare fraud. The data makes that easy to do by accident:

1949 (California, internal medicine), 1951 (Colorado, counselor), 1960 (New York, plastic surgery) and 1970 (Pennsylvania, general practice).

• 690 excluded people share the surname SMITH. 591 share JOHNSON.
• Four different excluded men are called some form of John Smith — born

So checkproviderexclusion never returns a boolean. It returns candidates with dateofbirth, state, city, specialty and npi, and a match_confidence describing what was actually matched:

Pass npi whenever you have it — it is the difference between a lead and an identification. Only 8,835 of 83,782 exclusions carry one, though, so for most records date of birth is the practical discriminator.

Currently excluded, not historically

Everyone on this list is currently excluded. The file has a reinstatement column and it is empty on every row, because OIG removes a reinstated party rather than flagging them. The ingest therefore deletes rows absent from each new file — "no longer listed" is how a reinstatement reaches you, and there is no expired state to read.

What this does not cover

State Medicaid exclusion lists, SAM.gov debarment, and licensure actions that have not led to an OIG exclusion. A clear result here is not a complete background check, and checkproviderexclusion says so on every no-match response.

Refreshing

Monthly, when OIG republishes:

node scripts/ingest-leie.mjs

Re-runnable: rows upsert on a content hash, and anything absent from the new file is deleted so reinstatements take effect. It refuses to load a file with fewer than 50,000 rows rather than quietly emptying the table.
