This page compares two distinct NUCC-taxonomy specialties tracked by the CMS National Plan and Provider Enumeration System: Driving and Community Mobility Occupational Therapist, which currently counts 108 enrolled providers across 35 U.S. states and territories, and Occupational Therapist, with 129,468 providers across 55 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 Driving and Community Mobility Occupational Therapist or Occupational 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, Occupational Therapist carries the larger provider roster (129,468 vs 108), and Occupational Therapist has the wider geographic footprint at 55 states versus 35. The top Driving and Community Mobility Occupational Therapist concentration sits in New York (19 providers), while Occupational Therapist peaks in New York (12,976). 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 — Driving and Community Mobility Occupational Therapist and Occupational 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.
