What this specialty covers

Reading the sole-proprietor share
For this specialty, 987 records, or 17.0%, are flagged as sole proprietors in NPPES. The flag is a self-reported NPPES field, so it is an imperfect proxy for private practice and does not by itself establish ownership, employment arrangement, or whether the clinician practices independently.

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 are administrative records and should not be treated as an exact count of unique, full-time, currently practicing physicians.
- Providers may report multiple taxonomy classifications, and the primary taxonomy reflects the classification selected in NPPES.
- State counts reflect NPPES records and reported locations, not patient volume, clinical hours, or the number of practices.
- Providers are counted once, by their primary taxonomy code only.
