89.7% of these records appear in a Medicare file, against 90.5% nationally

A Medicare file here is Part D prescribing (2024), a MIPS score (2023), an Open Payments record (2024) or Medicare group billing (CMS Doctors and Clinicians). A record outside them may still see patients: these files cover Medicare only.

What the count covers

3,099 NPPES records list hospitalist physician (208M00000X) as their primary taxonomy with a practice address in California: 8 per 100,000 residents against 8.3 nationally (50 states and D.C.). Los Angeles has 229 of them (7%).

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.
