What the count covers

231 NPPES records list otolaryngology physician (207Y00000X) as their primary taxonomy with a practice address in Wisconsin: 3.9 per 100,000 residents against 3.4 nationally (50 states and D.C.). Madison has 45 of them (19%).

A record is a registration a provider made and keeps up to date: it shows neither that the provider is licensed nor that they still practice there. The state's own license search is the check.
