13.5% of these records appear in a Medicare file, against 7.4% 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

927 NPPES records list registered dietitian (133V00000X) as their primary taxonomy with a practice address in Oregon: 22 per 100,000 residents against 20 nationally (50 states and D.C.). Portland has 358 of them (39%).

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.
