What the code means

A provider who is trained and educated in the performance of behavior health services through interpersonal communications and analysis. Training and education at the specialty level usually requires a master's degree and clinical experience and supervision for licensure or certification.

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.

Who registers under this code

106,253 of these are people and 5,387 are organisations, so 5% of the code is businesses rather than clinicians. Half of them had registered by 2017, and 35,563 registered in the last five years, 32% of the current population.

That is close to the pace of the registry as a whole.

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.

What else they list

Providers whose primary code is Counselor most often carry these secondary taxonomies as well. This is the closest thing the registry has to a map of which specialties overlap in practice, and it is not published anywhere else.

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.
