CPT® Code 93455

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

The CPT® Code 93455 refers to a specific medical procedure involving the placement of a catheter in the coronary arteries and bypass grafts for the purpose of conducting coronary angiography. This procedure is essential for visualizing the coronary arteries and any bypass grafts that may be present, allowing for a detailed assessment of blood flow and potential blockages. During the procedure, a local anesthetic is administered to the patient, and the skin over the access site is cleansed to minimize the risk of infection. A needle is used to puncture the artery, followed by the placement of a sheath to facilitate the insertion of a guidewire. The guidewire is carefully threaded through the artery and into the aorta, reaching the right or left coronary artery, or an arterial or venous bypass graft. Once the catheter is positioned correctly over the guidewire, the guidewire is removed, and contrast media is injected to enhance the visibility of the coronary structures during imaging. The angiograms obtained from this process provide critical information regarding the condition of the coronary arteries and grafts. After the imaging is completed, the catheter is withdrawn, and pressure is applied to the puncture site to prevent bleeding, followed by the application of a compression dressing. A thorough review of the angiograms is conducted, and a written interpretation of the findings is generated for further evaluation and treatment planning. It is important to note that CPT® Code 93455 is specifically used when the procedure involves both native coronary arteries and bypass grafts, whereas CPT® Code 93454 is designated for cases involving only native coronary arteries.
