ICD-10 Code I25.728 – Atherosclerosis of autologous artery coronary artery bypass graft(s) with other forms of angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.728 – Atherosclerosis of autologous artery coronary artery bypass graft(s) with other forms of angina pectoris
What it is
This code identifies atherosclerotic narrowing in an autologous coronary artery bypass graft, with angina that is not described as unstable or due to another specified pattern. Use it when the graft itself is the documented site of disease.
Clinical signs
Patients may report exertional chest discomfort, pressure, or reduced exercise tolerance. Findings should support ischemic heart disease involving a bypass graft; clinical features vary, so refer to documentation.
When to use this code
Use I25.728 when the provider documents atherosclerosis affecting an autologous coronary bypass graft and associates it with other forms of angina pectoris. This is appropriate when the graft lesion is the coded diagnosis, not native coronary disease alone. Check documentation for graft type and angina wording.
Do not use for
Do not use this code for angina without documented graft atherosclerosis, or for non-autologous graft disease. If the record does not specify the graft source or angina type, check documentation.
Coding tip
Verify that the bypass graft is autologous and that the angina is documented as “other forms” before assigning I25.728.
