A patient had atherosclerosis of the native first obtuse marginal artery and the native left anterior descending artery as well as aortic valve stenosis. While on cardiopulmonary bypass, he underwent an aortic valve replacement using a mechanical valve and two-vessel coronary artery bypass grafting procedure. The saphenous vein was used for the graft to the first obtuse marginal artery and the left radial artery was used for the graft to the left anterior descending artery. Select the appropriate CPT and ICD-10-CM codes.

Question

The correct coding involves 33405 for the aortic valve replacement with a mechanical valve, 33533-51 for the coronary artery bypass grafting (CABG) using one arterial graft (left radial artery to the left anterior descending artery), 35600 for the harvesting of the left radial artery, and 33517 for the saphenous vein graft to the first obtuse marginal artery. The ICD-10-CM codes I25.10 for atherosclerosis of the native arteries of the heart and I35.0 for nonrheumatic aortic valve stenosis accurately describe the patient's conditions.
