- Group: Allopathic & Osteopathic Physicians — code 46 of 238 in the group
- Classification: Internal Medicine 207R00000X

Choose 207RA0001X over the general Internal Medicine code (207R00000X) when the provider's training or certification is specifically in advanced heart failure and transplant cardiology; 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 207RA0001X to Medicare specialty 11 (Physician/Internal Medicine) and Medicare specialty C7 (Physician/Advanced Heart Failure and Transplant Cardiology). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 128,064 practitioners are enrolled under it nationally, and 25 other taxonomy codes map to the same specialty.

Using 207RA0001X
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.
