A psychologist who specializes in clinical health psychology that investigates and implements clinical services across diverse populations and settings to promote health and well-being and to prevent, treat, and manage illness and disability.

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
452 of these are people and 110 are organisations, so 20% of the code is businesses rather than clinicians. Half of them had registered by 2016, and 151 registered in the last five years, 27% 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.
