Occupational Therapist in Private Practice: Medicare enrollment by state

Taxonomy codes for occupational therapist in private practice

CMS's crosswalk maps 13 NUCC taxonomy codes to Medicare specialty 67. A provider enrolling as occupational therapist in private practice should hold one of them as the primary taxonomy on their NPI.

Where it is concentrated

Raw counts follow population, so the more telling figure is each state's share: what fraction of the state's Medicare-enrolled NPIs are occupational therapist in private practice. Nationally the specialty is 1% of enrolled NPIs. The highest shares are in North Dakota (2.1%), New Jersey (1.8%), Minnesota (1.8%); the lowest in Vermont (0.2%), New Mexico (0.4%), Hawaii (0.5%). 51 of the 51 (50 states and DC) have at least one enrolled.

Billing versus order-and-refer enrollment

Medicare enrolls practitioners in two ways. A full enrollment lets the provider bill Medicare for their own services; it is what the 24,487 above count. An order-and-refer-only enrollment lets a provider who never bills Medicare — a resident, a VA or military physician, a dentist ordering imaging — still order tests, equipment and referrals that Medicare pays for. No occupational therapist in private practice NPIs hold that limited enrollment in the current file.

Every state

Counts are unique NPIs enrolled in each state; a provider enrolled in two states counts in both. The share is of all Medicare-enrolled NPIs in that state.
