National totals

What this specialty covers

An organization that provides prosthetic and orthotic care which may include, but is not limited to, patient evaluation, prosthesis or orthosis design, fabrication, fitting and modification to treat limb loss for purposes of restoring physiological function and/or cosmesis or to treat a neuromusculoskeletal disorder or acquired condition.

Reading the sole-proprietor share

For this specialty, 943 records, or 12.0%, are flagged as sole proprietors in NPPES. This is an imperfect proxy for private practice because the field is self-reported and does not by itself establish ownership, employment arrangements, affiliations, or how a supplier operates.

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 NPIs with this taxonomy as the primary classification and may not represent unique organizations, locations, or clinicians.
• Enumeration-year counts do not measure net growth, service volume, or clinical capacity.
• Providers are counted once, by their primary taxonomy code only.
