61.9% of these records appear in a Medicare file, against 70.0% 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
4,226 NPPES records list psychiatric/mental health nurse practitioner (363LP0808X) as their primary taxonomy with a practice address in California: 11 per 100,000 residents against 17 nationally (50 states and D.C.). Los Angeles has 364 of them (9%).
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.
