No NUCC taxonomy code maps to Medicare specialty F6 in the current crosswalk.

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 epileptologists. Nationally the specialty is 0% of enrolled NPIs. The highest shares are in California (0%), Illinois (0%), Colorado (0%); the lowest in Wyoming (0%), North Carolina (0%), Idaho (0%). 35 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 361 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. 9 epileptologists 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.
