What this specialty covers
An entity, facility, or distinct part of a facility providing diagnostic, treatment, and prescriptive services related to mental and behavioral disorders in adults.
Reading the sole-proprietor share
For this specialty, 248 records, or 2.3%, are flagged as sole proprietors in NPPES. This self-reported field is an imperfect proxy for private practice because it does not by itself establish ownership, employment arrangement, independence, or whether a site operates as a solo practice.

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.
- - The count covers active NPI records with 261QM0850X as the primary taxonomy, not all organizations, locations, clinicians, or services.
- - First-enumeration years describe when an NPI was issued, not when a clinic opened or began serving adults.
- Providers are counted once, by their primary taxonomy code only.
