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 conduit. What codes would we report for this?
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|
In CPT Assistant, December 2011, the American Medical Association states, “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.”
