What the count covers

634 NPPES records list thoracic surgery (cardiothoracic vascular surgery) physician (208G00000X) as their primary taxonomy with a practice address in California: 1.6 per 100,000 residents against 1.9 nationally (50 states and D.C.). Los Angeles has 103 of them (16%).

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.
