What the count covers

69 NPPES records list occupational medicine physician (2083X0100X) as their primary taxonomy with a practice address in Maryland: 1.1 per 100,000 residents against 0.8 nationally (50 states and D.C.). Bethesda has 12 of them (17%).

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.
