What the code means
An entity, facility, or distinct part of a facility providing diagnostic, and replacement maintenance treatment services related to individuals with drug addiction.
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
50 of these are people and 1,635 are organisations, so 97% of the code is businesses rather than clinicians. Half of them had registered by 2015, and 411 registered in the last five years, 24% 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.
