This page compares two distinct NUCC-taxonomy specialties tracked by the CMS National Plan and Provider Enumeration System: Orthopedic Physical Therapist, which currently counts 10,613 enrolled providers across 51 U.S. states and territories, and Physical Therapist, with 255,818 providers across 56 states. Each clinician on these rosters selected a primary NUCC code at NPI enrollment, so the totals measure how many providers self-identify their primary practice as Orthopedic Physical Therapist or Physical Therapist rather than the total population ever trained or credentialed in either field — dual-certified clinicians show up under whichever code they registered first.

On national volume, Physical Therapist carries the larger provider roster (255,818 vs 10,613), and Physical Therapist has the wider geographic footprint at 56 states versus 51. The top Orthopedic Physical Therapist concentration sits in California (1,554 providers), while Physical Therapist peaks in California (21,951). The per-capita columns in the table below normalize each state's raw count against 2023 Census population estimates, which matters because absolute provider counts track population scale first and specialty density second — a small state with a strong training pipeline can out-rank a larger state on per-100K availability.

Use this comparison to understand relative availability, not to judge clinical substitutability — Orthopedic Physical Therapist and Physical Therapist are distinct specialties with different scopes of practice, training requirements, and conditions they treat, even when their NUCC categories overlap. Important: PlainDoctor is a directory of publicly available CMS government data, not medical advice, a provider rating, or a recommendation about which specialty a patient should consult. Always work with a licensed clinician to determine which specialty is appropriate for your condition, verify any specific provider through the NPPES NPI Registry and the relevant state medical board, and consult the NUCC taxonomy documentation for the formal scope-of-practice definitions behind each specialty code.
