CPT® Code 93454

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

The CPT® Code 93454 refers to the procedure of catheter placement in the coronary arteries for the purpose of conducting coronary angiography. This procedure includes the necessary intraprocedural injections for the angiography, as well as the imaging supervision and interpretation that accompany it. In simpler terms, this involves inserting a catheter into the coronary arteries, which may also include arterial and/or venous coronary bypass grafts, to visualize the blood vessels of the heart. The process begins with the cleansing of the skin at the site where the catheter will be inserted, followed by the administration of a local anesthetic to minimize discomfort. A needle is then used to puncture the artery, and a sheath is placed to facilitate the insertion of a guidewire. This guidewire is carefully threaded through the artery and into the aorta, ultimately reaching the right or left coronary artery or a bypass graft. Once the guidewire is in place, a catheter is advanced over it, and the guidewire is subsequently removed. Contrast media is injected through the catheter to enhance the visibility of the coronary arteries and bypass grafts during imaging. Angiograms are then obtained to assess the condition of these vessels. After the angiography is completed, the catheter is withdrawn, and pressure is applied to the puncture site to prevent bleeding, followed by the application of a compression dressing. Finally, the angiograms are reviewed, and a written interpretation of the findings is generated. It is important to note that CPT® Code 93454 should be used when the catheterization and angiography are performed solely on native coronary arteries, while CPT® Code 93455 is applicable when the procedure involves both native coronary arteries and bypass grafts.
