67.1% of these records appear in a Medicare file, against 75.1% 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

16,966 NPPES records list family nurse practitioner (363LF0000X) as their primary taxonomy with a practice address in California: 44 per 100,000 residents against 71 nationally (50 states and D.C.). Los Angeles has 1,103 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.
