A patient was brought to the cardiac cath lab, and only coronary bypass grafts were visualized. No native coronary arteries were injected or imaged, and no heart cath was performed. What is the appropriate CPT® procedure code to assign?


The American Medical Association has said that the coronary angiogram with grafts code (93455) should be reported.

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

Because the procedure performed is less than what the code descriptor requires, add modifier
-52 (reduced services).
