What the code means
A masters trained health care provider who collects and interprets genetic family histories; assesses the risk of disease occurrence or recurrence; identifies interventions to manage or ameliorate disease risk; educates about inheritance, testing, management, prevention, ethical issues, resources, and research; and counsels to promote informed choices and adaptation. Certification was established in 1993 by the American Board of Genetic Counseling and prior to that by the American Board of Medical Genetics. Requirements for experience, licensure, and job responsibilities vary among the states.

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
6,549 of these are people and 76 are organisations, so 1% of the code is businesses rather than clinicians. Half of them had registered by 2018, and 2,352 registered in the last five years, 36% 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.

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.
