What CPT® codes are associated with aortic valve replacement and coronary artery bypass grafting in a critical aortic valve stenosis case?

The correct response relates specifically to the procedures involved in aortic valve replacement and coronary artery bypass grafting due to critical aortic valve stenosis.

In this case, the CPT® code 33405 is designated for aortic valve replacement, either via a mechanical or bioprosthetic approach, and it reflects the procedural aspects of addressing the aortic valve issues associated with stenosis. The other codes in the choice, 33511-51 and 33508, refer to coronary artery bypass grafting procedures. Specifically, 33511 is used for bypass grafting of one coronary artery, while 33508 indicates the use of an arterial graft for the bypass.

Additionally, the use of the modifier -51 in coding indicates that multiple procedures were performed during the same surgical session, which is relevant to accurately reporting the complex surgical intervention that involves both valve replacement and bypass grafting.

This combination accurately captures the surgical treatment strategy for a patient experiencing critical aortic valve stenosis requiring both an aortic valve replacement and coronary artery bypass grafting. Other choices contain varying combinations of these codes which may not accurately represent the procedure being described, hence leading to their inapplicability in this scenario.
