36.4% of these records appear in a Medicare file, against 17.0% 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

938 NPPES records list specialist (174400000X) as their primary taxonomy with a practice address in Maryland: 15 per 100,000 residents against 18 nationally (50 states and D.C.). Baltimore has 207 of them (22%).

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.
