Definition

An area of medicine within the subspecialty of cardiology, which uses specialized imaging and other diagnostic techniques to evaluate blood flow and pressure in the coronary arteries and chambers of the heart and uses technical procedures and medications to treat abnormalities that impair the function of the cardiovascular system.

— NUCC Health Care Provider Taxonomy, version 26.1

Where 207RI0011X sits

Choose 207RI0011X over the general Internal Medicine code (207R00000X) when the provider's training or certification is specifically in interventional 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 207RI0011X to Medicare specialty C3 (Physician/Interventional Cardiology). That specialty — not the taxonomy code itself — is what Medicare enrollment records and uses for payment. 5,759 practitioners are enrolled under it nationally.

Using 207RI0011X

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.
