What the count covers

1,088 NPPES records list ophthalmology physician (207W00000X) as their primary taxonomy with a practice address in Pennsylvania: 8.4 per 100,000 residents against 6.7 nationally (50 states and D.C.). Philadelphia has 256 of them (24%).

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.
