Cardiology Question for the Week of August 29, 2016

Question:

Question:

Our doctor performed a coronary angiogram and then a left internal mammary artery (LIMA) angiogram to determine if the LIMA was suitable to use as a bypass graft. What code would we report for this?

Answer:

Answer:

You would report the following code:

93455 Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision and interpretation; with catheter placement(s) in bypass graft(s) (internal mammary, free arterial, venous grafts) including intraprocedural injection(s) for bypass graft angiography

The American Medical Association says that, when evaluating a potential graft during a heart cath/coronary angiogram, the appropriate grafts code should be assigned. As stated in CPT® Assistant, December 2011:

“To further clarify, in the uncommon situation in which angiography of the right or left internal mammary artery is performed to determine suitability for use during future bypass surgery (eg, due to prior thoracic surgery or radiation), the appropriate diagnostic cardiac catheterization with angiography code (93455, 93457, 93459, or 93461) should be reported based on the total catheterization components performed.”
