Frequently asked questions

How do I find NPI providers by specialty?

Pick a specialty below to open its directory of providers, then narrow by state and city. Each provider profile shows the NPI number, taxonomy code, and practice location.

How is a specialty different from a taxonomy code?

A specialty is a plain-English grouping of one or more NUCC taxonomy codes. For example, the Family Medicine specialty gathers the family-medicine taxonomy codes providers select in NPPES.

Why do the provider counts vary?

Each count reflects how many providers in our latest NPPES snapshot use a taxonomy code mapped to that specialty. Larger specialties like nursing and family medicine have the most providers.
