What the code means

Occupational therapists provide treatment for people recovering from a mental or physical illness to regain their independence and stability and to engage in normal daily occupations (work, home, family life, school, leisure). Occupational therapists provide particular emphasis on interventions that result in improved quality of life and decrease hospitalization.

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 48 states with at least one.

Who registers under this code

513 of these are people and 60 are organisations, so 10% of the code is businesses rather than clinicians. Half of them had registered by 2020, and 265 registered in the last five years, 46% 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.

What else they list

Providers whose primary code is Mental Health Occupational Therapist 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.
