Atherosclerosis of autologous artery coronary artery bypass graft(s) with angina pectoris with documented spasm
ICD-10 I25.721 is a billable code used to indicate a diagnosis of atherosclerosis of autologous artery coronary artery bypass graft(s) with angina pectoris with documented spasm.
I25.721 refers to atherosclerosis of autologous artery coronary artery bypass graft(s) with angina pectoris with documented spasm. This condition arises when there is a buildup of plaque in the grafted arteries used for bypass surgery, leading to narrowed or blocked blood flow. Patients typically present with angina pectoris, which is characterized by chest pain or discomfort due to reduced blood flow to the heart muscle. The documented spasm indicates that there are episodes of transient constriction of the coronary arteries, which can exacerbate the angina symptoms. The anatomy involved includes the coronary arteries that have been bypassed using autologous veins or arteries, such as the saphenous vein or internal mammary artery. Disease progression may lead to worsening angina, myocardial ischemia, and potentially myocardial infarction if not managed appropriately. Diagnostic considerations include patient history, physical examination, stress testing, and imaging studies such as angiography to assess graft patency and coronary artery status.

I25.721 covers atherosclerosis affecting autologous artery grafts used in coronary artery bypass surgery, specifically when patients experience angina pectoris accompanied by documented coronary artery spasm.
I25.721 should be used when there is clear documentation of atherosclerosis in bypass grafts with associated angina and spasm, distinguishing it from other codes that may not involve grafts or spasm.
Documentation should include a detailed history of angina symptoms, results from diagnostic tests confirming graft involvement, and evidence of documented coronary artery spasm.
