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

Quizplus · Accepted Answer

The correct CPT codes for this procedure are 33405 for the aortic valve replacement using a mechanical valve, 33533 for the two-vessel coronary artery bypass grafting (CABG) procedure (one with the saphenous vein and the other with the left radial artery), and 35600 for the use of the left radial artery as a graft. Modifier -51 is used with 33533 to indicate that multiple procedures were performed during the same surgical session. The correct ICD-10-CM codes are I25.10 for atherosclerosis of the native arteries of the heart and I35.0 for aortic valve stenosis.
