What the code means

A medical geneticist works in association with a medical specialist, is affiliated with a clinical genetics program, and serves as a consultant to medical and dental specialists.

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 45 states with at least one.

Who registers under this code

309 of these are people and 229 are organisations, so 43% of the code is businesses rather than clinicians. Half of them had registered by 2007, and 40 registered in the last five years, 7% of the current population.

That is a slow-growing code, which usually means an established field replacing retirements rather than expanding.

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 Ph.D. Medical Genetics 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.
