Question:
How would you code this scenario? An interventional cardiologist performs a PTCA in the LAD artery. The physician also performed angioplasty in the diagonal side branch of the patient’s LAD during the same session.
Answer:
In a physician setting, you would code 92920-LD, 92921-LD and in a hospital setting, you would code 92920-LD, 92921-LD. PTCA primary code (92920 ) is assigned for the PTCA performed in the LAD (major coronary artery). Because a branch vessel was treated in the same territory as the initial intervention, the PTCA of the diagonal branch is coded with add-on code 92921. Per CPT, add-on codes may only be assigned when treating additional vessels (no more than two) in the LAD, LCX, or RCA.
