What the code means
(1) An unlicensed individual who is trained to function in an assistive role to the licensed nurse in the provision of patient/client activities as delegated by the nurse; (2) An individual trained (either on-the-job or through a formal course generally of less than one year) and experienced in performing patient or client-care nursing tasks that do not require the skills of a specialist, technician, or professional. Examples of tasks performed by nurses aides include changing clothes, diapers, and beds; assisting patients to perform exercises or personal hygiene tasks, and supporting communication or social interaction. Specific education and credentials are not required for this work.

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
13,591 of these are people and 405 are organisations, so 3% of the code is businesses rather than clinicians. Half of them had registered by 2020, and 6,585 registered in the last five years, 47% 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.
