Athscl autologous vein CABG w oth angina pectoris

This code signifies the presence of atherosclerosis specifically affecting an autologous vein graft used in a coronary artery bypass procedure. The patient is also experiencing other forms of angina pectoris, indicating symptomatic coronary artery disease within the grafted vessel.

This code is appropriate when documentation clearly indicates a patient with a history of coronary artery bypass grafting using an autologous vein, who is now presenting with angina due to atherosclerotic changes within that specific graft. The physician's notes should explicitly state both the graft atherosclerosis and the presence of angina.

• Ensure the documentation specifies an autologous vein graft, as other graft types have different codes.
• Confirm the presence of "other forms of angina pectoris" as the symptomatic manifestation.
• Do not code with I20.8- (other forms of angina pectoris without atherosclerosis of autologous vein coronary artery bypass graft(s)) due to the Excludes1 note.
