General classification identifying individuals trained on specific equipment and technical procedures in one of a collection of miscellaneous healthcare disciplines.
Reading the sole-proprietor share
In this specialty, 706 of 2,394 active records, or 29.5%, carry the sole-proprietor flag. The field is self-reported in NPPES and is an imperfect proxy for private practice, so it does not by itself establish ownership, employment status, or practice setting.

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.
- An NPI record is not a direct census of people, organizations, locations, or currently practicing providers.
- This broad taxonomy can include people working in different technical disciplines, so the total does not identify a single job or service.
- Providers are counted once, by their primary taxonomy code only.
