Neuropsychiatry: Medicare enrollment by state

Taxonomy codes for neuropsychiatry

CMS's crosswalk maps 20 NUCC taxonomy codes to Medicare specialty 86. A provider enrolling as neuropsychiatry 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 neuropsychiatry. Nationally the specialty is 0% of enrolled NPIs. The highest shares are in Kentucky (0.1%), California (0%), Florida (0%); the lowest in Oregon (0%), Vermont (0%), Nevada (0%). 45 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 436 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. 4 neuropsychiatry NPIs hold that limited enrollment.

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.
