What the code means
An organization including a physical plant and personnel that provides multidisciplinary diagnostic and treatment mental health services to patients requiring the safety, security, and shelter of the inpatient or partial hospitalization settings.
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
184 of these are people and 2,240 are organisations, so 92% of the code is businesses rather than clinicians. Half of them had registered by 2009, and 281 registered in the last five years, 12% of the current population.
That is a slow-growing code, which usually means an established field replacing retirements rather than expanding.
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 Psychiatric Hospital 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.
