MS SPECIALTY CODES/HEALTHCARE PROVIDER
TAXONOMY CROSSWALK
This document “walks” the CMS Medicare specialty codes to the taxonomy codes currently
maintained by the Washington Publishing Company as mandated by the Health Insurance
Portability and Accountability Act (HIPAA) of 1996. Although this crosswalk is geared more
for Medicare contractor use, this could assist current Medicare providers and suppliers in
determining their taxonomy if they are required to use it on a claim form.
