A home-like residential facility providing psychiatric treatment and psycho/social rehabilitative services to individuals diagnosed with mental illness.
Reading the sole-proprietor share
For this specialty, 528 records, or 9.8%, are flagged as sole proprietors in NPPES. This is a self-reported field and an imperfect proxy for private practice because it does not by itself establish ownership, independence, or how a residential program is operated.

Data notes
- The sole-proprietor field is self-reported by the provider in NPPES and is an imperfect proxy for private practice.
- A sole-proprietor count shown as <11 is suppressed: the true value is below 11, which could include zero.
- NPI records do not necessarily equal distinct facilities, locations, beds, or service volume.
- The primary taxonomy is an NPPES classification that can be updated and may not capture every service a provider offers.
- Providers are counted once, by their primary taxonomy code only.
