NUCC taxonomy
Every specialty in the registry
NUCC publishes 870 provider taxonomies. 584 of them have at least 250 active providers and get a page here, grouped the way NUCC groups them.
A taxonomy is what a provider says they do, not what a licensing board certified them to do. Providers pick their own, and can list up to fifteen. Every count below uses the one flagged primary.

Why some taxonomies are missing
Taxonomies below 250 active providers are left out. Below that the state breakdown is one or two people per state, which tells you nothing and identifies individuals in a way a count is not supposed to. They still resolve on a provider record, they just have no page of their own.
Counts from npidata_pfile_20050523-20260712.csv, built 2026-08-09.
