## About these facts

- Status words: How each fact is known. confirmed = Listed: a named directory, CMS file or state file lists it. inferred = Likely: a price file suggests it; a likely match is a lead, not a listing. self-reported: the clinician said it, to the NPPES registry or on Gale. not-listed: a source that lists every clinician it covers was read and does not list this one; that is not a no. unknown: no record; ask the office.
- Dates: The date the source gives this record (YYYY-MM-DD). It is not the date of the event the record describes: an opt-out states its own start and end dates in its sentence.
- Hash: Changes only when a fact changes, never on a re-check.
