CPT® Code 93456

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

The procedure described by CPT® Code 93456 involves catheter placement in the coronary arteries for the purpose of conducting coronary angiography. This procedure is essential for visualizing the coronary arteries and any bypass grafts that may be present. It includes the administration of intraprocedural injections necessary for the angiography, as well as the imaging supervision and interpretation of the results. The process begins with the preparation of the patient, which includes 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 threaded through the artery and into the aorta, allowing for the placement of a catheter that will enable the injection of contrast media. This contrast media is crucial for visualizing the coronary arteries and any bypass grafts during the angiogram. After the angiographic images are obtained, the catheter is withdrawn, and pressure is applied to the puncture site to prevent bleeding, followed by the application of a compression dressing. Additionally, the procedure includes right heart catheterization, which involves accessing the femoral vein to evaluate the right side of the heart and pulmonary arteries. This comprehensive approach allows for a thorough assessment of both the coronary and right heart structures, providing valuable information for diagnosis and treatment planning.
