CPT® Code 93460

Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation; with right and left heart catheterization including intraprocedural injection(s) for left ventriculography, when performed

The procedure described by CPT® Code 93460 involves the placement of a catheter in the coronary arteries for the purpose of conducting coronary angiography. This procedure is comprehensive, as it includes intraprocedural injections necessary for the angiography, as well as the imaging supervision and interpretation required to assess the coronary arteries. Additionally, this code encompasses right and left heart catheterization, which also involves intraprocedural injections for left ventriculography when performed. The process begins with the preparation of the patient, including cleansing the skin over the arterial access site and administering a local anesthetic to minimize discomfort. Following this, a needle is used to puncture the artery, and a sheath is placed to facilitate the insertion of a guidewire. The guidewire is carefully navigated through the arterial system into the coronary arteries or bypass grafts, allowing for the subsequent placement of a catheter. Once the catheter is in position, contrast media is injected to visualize the coronary arteries and any bypass grafts, enabling the acquisition of angiograms. The procedure also includes right heart catheterization, typically accessed via the right femoral vein, and left heart catheterization, which is often performed through the same access point as the coronary arteries. This thorough examination allows for the assessment of heart chambers, valve function, and pressure measurements, culminating in a detailed report of the findings.
