What the code means

Definition quoted verbatim from the NUCC Health Care Provider Taxonomy code set, version 25.1. Not paraphrased.

Where they are

Counted by practice location, not by mailing address or by licence state. A provider practising across a state line is counted where they practise.

Showing the 15 largest of 51 states with at least one.

Who registers under this code

11,077 of these are people and 1,887 are organisations, so 15% of the code is businesses rather than clinicians. Half of them had registered by 2020, and 5,769 registered in the last five years, 45% of the current population.

That is a fast-growing code. A population where a large share registered recently is either a genuinely expanding field or a category NPPES added late, and the taxonomy definition above usually tells you which.

Where the practices are

By practice-location city. City counts are noisier than state counts, because a large employer files one address for many providers.

Looking up a specific provider

These counts come from the monthly NPPES file. To check one provider, use their NPI: the lookup reads the live registry and shows whether the identifier is still active, which the monthly file cannot tell you about the last few weeks.
