What the code means
A perfusionist operates extracorporeal circulation and autotransfusion equipment during any medical situation where it is necessary to support or temporarily replace the patient's circulatory or respiratory function. The perfusionist is knowledgeable concerning the variety of equipment available to perform extracorporeal circulation functions and is responsible, in consultation with the physician, for selecting the appropriate equipment and techniques to be used.

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
1,541 of these are people and 34 are organisations, so 2% of the code is businesses rather than clinicians. Half of them had registered by 2020, and 706 registered in the last five years, 45% 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.
