What the code means
Definition to come...

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
12,832 of these are people and 147 are organisations, so 1% of the code is businesses rather than clinicians. Half of them had registered by 2020, and 6,470 registered in the last five years, 50% of the current population.
That is a fast-growing code. A population where a large share registered recently is either a genuinely expanding field or a category NPPES added late, and the taxonomy definition above usually tells you which.
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.
