Combined left heart catheterization, coronary angiography, and bypass graft angiography.
Modifiers such as 22 (increased procedural services), 52 (reduced services), and others may be applicable depending on the specific circumstances of the procedure.
Medical necessity is established by the clinical indication for the procedure, such as angina, shortness of breath, or abnormal stress test results, especially in patients with a history of bypass surgery.
The physician inserts a catheter into an artery, usually in the groin or arm, and guides it to the heart. Dye is injected into the coronary arteries, bypass grafts, and left ventricle while X-ray images are taken. The physician supervises the imaging process, interprets the images, and creates a report.
In simple words: This procedure involves taking images of the heart's arteries and any bypass grafts using a catheter inserted into a blood vessel. Dye is injected to visualize blood flow, helping identify blockages or narrowing. It also includes assessing the left side of the heart.
Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation; with left heart catheterization including intraprocedural injection(s) for left ventriculography, when performed, catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) with bypass graft angiography.
Example 1: A patient with a history of bypass surgery and recent chest pain undergoes this procedure to check for new blockages in the grafts and native coronary arteries, and assess left ventricle function., A patient with unstable angina and prior bypass surgery has this procedure to evaluate the function of bypass grafts and determine the need for further intervention., A patient with suspected coronary artery disease and previous bypass surgery undergoes this procedure as part of a pre-operative assessment for another cardiac surgery.
Documentation should include the reason for the procedure, the access site used, the coronary arteries and bypass grafts visualized, the left ventriculogram findings, any complications, and the interpretation report.
