Who registers under this code
3,569 of these are people and 435 are organisations, so 11% of the code is businesses rather than clinicians. Half of them had registered by 2007, and 92 registered in the last five years, 2% 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.

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.
