WHAT YOU NEED TO KNOW The underlying data is free from CMS. You are paying for the cleaned, filtered and flagged file, not for exclusive data. Organisations only: no individual practitioners, no authorised-official names and no phone numbers. An NPI is an identifier assigned on application. It is not a licence, and a new or updated record is not proof that a practice is open or operating. Organisation type comes from the taxonomy codes each organisation reported itself. Deactivated organisations are removed when the monthly full file is refreshed (next refresh: 2026-11-10). This is not a complete or verified directory of every provider. Prefer a single download?
