NPPES Taxonomy Classification
Every doctor in the United States is assigned a unique NPI (National Provider Identifier) number and one or more specialty taxonomy codes. These taxonomy codes identify the precise medical specialty, sub-specialty, or practice type of the provider.
DATFYT provides a live, searchable interface connected directly to the NPPES (National Plan and Provider Enumeration System) registry, allowing you to query verified physician data by specialty, state, city, or NPI number.
Why Specialty Search Matters
Medical billing teams, credentialing managers, insurance networks, and healthcare organizations rely on accurate specialty classification to route patients, verify credentials, and audit network coverage gaps.
With DATFYT's Work Center and AI Doctor Agent, you can query any specialty, bookmark provider lists, and export datasets instantly to Excel — all in one platform.
