What the code means

An individual with post-high school vocational training and practical experience in the provision of nursing care at a level less than that required for certification as a Registered Nurse. Requirements for education, experience, licensure, and job responsibilities vary among the states.

Definition quoted verbatim from the NUCC Health Care Provider Taxonomy code set, version 25.1. Not paraphrased.

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

Almost all of these are individual clinicians: 71,993 people against 464 organisations. Half of them had registered by 2016, and 21,886 registered in the last five years, 30% 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.

What else they list

Providers whose primary code is Licensed Practical Nurse most often carry these secondary taxonomies as well. This is the closest thing the registry has to a map of which specialties overlap in practice, and it is not published anywhere else.

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.
