Our interventional cardiologist performed a PTCA in the LAD, an atherectomy in the RCA, and placed a drug-eluting stent in the left circumflex artery (LC). How would we code for this?
For a physician setting, you would code 92928-LC, 92924-RC, and 92920-LD. For a hospital setting, code C9600-LC, 92924-RC, and 92920-LD. Three primary codes are reported because treatment was performed within each of the three major coronary arteries. Current coding rules state that you must have a single base/initial vessel code in each of the five primary coronary arteries before add-on codes are assigned. The PTCA in the LAD is coded with CPT 92920; the atherectomy performed on the RCA is reported with code 92924 and the DES deployed within the LCX is reported with code 92928 (for physicians) or C9600 (for Medicare hospital billing).
