What the count covers

33 NPPES records list hematology (internal medicine) physician (207RH0000X) as their primary taxonomy with a practice address in Maryland: 0.5 per 100,000 residents against 0.4 nationally (50 states and D.C.). Bethesda has 16 of them (48%).

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.
