What the count covers

588 NPPES records list ophthalmology physician (207W00000X) as their primary taxonomy with a practice address in Maryland: 9.5 per 100,000 residents against 6.7 nationally (50 states and D.C.). Baltimore has 210 of them (36%).

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.
