HCPCS 93459

Left heart catheterization including intraprocedural injection(s) for left ventriculography, when performed, catheter placement in coronary artery(s) for coronary angiography, with catheter placement in bypass graft(s)

AI EXPLANATION: A coronary angiogram with bypass graft imaging is a specialized heart procedure used to check blood flow in the heart's natural arteries and in any bypass grafts from previous surgery. A doctor gently threads a thin, flexible tube called a catheter through a blood vessel to the heart. Special dye that shows up on X-rays is injected into the coronary arteries and bypass vessels, allowing real-time images to reveal blockages, assess blood flow, and examine the function of the heart's main pumping chamber.
