I am new at coding for cardiologist. How should I code CABG involving the left internal mammary artery to the left anterior descending and saphenous vein grafts to 3 coronary arteries.

Based on the description, there appears to be one arterial graft and three venous grafts. In that case, you should report:
* 33533, Coronary artery bypass, using arterial graft(s); single arterial graft
* +33519, Coronary artery bypass, using venous graft(s) and arterial graft(s); 3 venous grafts (List separately in addition to code for primary procedure).
CPT® guidelines indicate that the arterial grafting codes (like 33533) include the use of the internal mammary artery, which helps support that code choice in your case.
Note that CPT® guidelines also state that harvesting the saphenous vein graft is included in 33517-33523, so you should not separately report the graft procurement.
