67.6% of these records appear in a Medicare file, against 67.5% 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

1,018 NPPES records list endodontics (1223E0200X) as their primary taxonomy with a practice address in California: 2.6 per 100,000 residents against 2 nationally (50 states and D.C.). San Diego has 54 of them (5%).

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.
