Who registers under this code
657 of these are people and 308 are organisations, so 32% of the code is businesses rather than clinicians. Half of them had registered by 2012, and 223 registered in the last five years, 23% 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.
