CPT® Code 93459

Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation; with left heart catheterization including intraprocedural injection(s) for left ventriculography, when performed, catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) with bypass graft angiography

CPT® Code 93459 refers to a comprehensive procedure involving catheter placement in the coronary arteries for the purpose of coronary angiography. This procedure includes the administration of intraprocedural injections specifically for coronary angiography, along with the necessary imaging supervision and interpretation. Additionally, it encompasses left heart catheterization, which also involves intraprocedural injections for left ventriculography when performed. The procedure is further extended to include catheter placements in bypass grafts, such as internal mammary, free arterial, or venous grafts, along with bypass graft angiography. The overall aim of this procedure is to visualize the coronary arteries and any bypass grafts, assess their condition, and evaluate the function of the left heart structures. The detailed steps of the procedure ensure that healthcare professionals can accurately diagnose and manage coronary artery disease and related conditions.
