- Group: Allopathic & Osteopathic Physicians — code 110 of 238 in the group
- Classification: Orthopaedic Surgery 207X00000X
- Specialization: Foot and Ankle Surgery 207XX0004X
Choose 207XX0004X over the general Orthopaedic Surgery code (207X00000X) when the provider's training or certification is specifically in foot and ankle surgery; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
CMS's taxonomy crosswalk links 207XX0004X to Medicare specialty 02 (Physician/General Surgery) and Medicare specialty 20 (Physician/Orthopedic Surgery).

Using 207XX0004X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
