CPT® Code 93564

Add-On Code

Injection procedure during cardiac catheterization including imaging supervision, interpretation, and report; for selective opacification of aortocoronary venous or arterial bypass graft(s) (eg, aortocoronary saphenous vein, free radial artery, or free mammary artery graft) to one or more coronary arteries and in situ arterial conduits (eg, internal mammary), whether native or used for bypass to one or more coronary arteries during congenital heart catheterization, when performed (List separately in addition to code for primary procedure)

An injection procedure is conducted during cardiac catheterization to achieve selective opacification of aortocoronary venous or arterial bypass grafts. This procedure is particularly relevant for patients with congenital cardiac anomalies. During the process, a catheter is carefully positioned within the venous or arterial bypass graft, which may include grafts such as the aortocoronary saphenous vein, free radial artery, or free mammary artery. Once the catheter is in place, contrast media is injected to enhance the visibility of the grafts. This allows for the visualization of the bypass grafts and the acquisition of selective angiograms. If further evaluation is necessary, the catheter can be repositioned to access additional bypass grafts, and the injection procedure is repeated to ensure comprehensive imaging. The resulting angiograms are meticulously reviewed by the physician, who then provides a written interpretation of the findings. It is important to note that this code should be reported separately in addition to the primary procedure code for the cardiac catheterization performed on the patient.
