What the code means
A psychologist who specializes in geropsychology, which applies the knowledge and methods of psychology to understanding and helping older persons and their families to maintain well-being, overcome problems and achieve maximum potential during later life. Professional geropsychology appreciates the wide diversity among older adults, the complex ethical issues that can arise in geriatric practice and the importance of interdisciplinary models of care.

Who registers under this code
286 of these are people and 65 are organisations, so 19% of the code is businesses rather than clinicians. Half of them had registered by 2015, and 126 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.
