Where this comes from
The crosswalk is CMS's Medicare Provider and Supplier Taxonomy Crosswalk, the August 2026 file. The taxonomy descriptions are the NUCC's wording (code set). The Medicare codes for facilities and suppliers, such as ambulance services and hospitals, are not here, since the CMS Doctors and Clinicians file lists people.
Counts are from the CMS Doctors and Clinicians file dated Aug 18, 2026: the NPIs enrolled under each primary specialty. We matched each CMS primary specialty to its Medicare code by name; a handful whose names differ, such as hospice and palliative care and cardiac electrophysiology, were matched by hand against the crosswalk. Primary specialties with no Medicare code in the crosswalk (some dental specialties and “undefined” types) are left out.
For the same clinicians by state, see doctors per capita by state and specialty.
Questions about these codes
What is a Medicare specialty code?
A two-character code CMS uses for the specialty a clinician or supplier enrolls under, and the one printed on a claim. 06 is Cardiovascular Disease (Cardiology) and 11 is Internal Medicine. This table lists 84 of them: the ones that match a primary specialty in the CMS Doctors and Clinicians file.
What is a taxonomy code?
A ten-character code from the NUCC Health Care Provider Taxonomy code set. A clinician lists one or more of them when they register for an NPI, to say what kind of provider they are. 207RC0000X is Allopathic & Osteopathic Physicians/Internal Medicine, Cardiovascular Disease.
How do Medicare specialty codes relate to taxonomy codes?
CMS publishes a crosswalk from each Medicare specialty code to the taxonomy codes that fit it. The August 2026 crosswalk gives 422 pairs across the 84 specialties here. One Medicare code can map to many taxonomy codes: Certified Clinical Nurse Specialist has 34.
Why do some specialties have no list link?
We sell a list for the specialties that physicians, nurse practitioners, physician assistants, chiropractors and optometrists work in, 36 in all. The rest of the table is here for reference.
Where does the clinician count come from?
The CMS Doctors and Clinicians national downloadable file dated Aug 18, 2026. It counts NPIs enrolled in Medicare under each primary specialty. A clinician with enrollments under two specialties is counted under both, so the counts add up to more than the number of distinct clinicians.
