ICD-10 Code I25.70 – Atherosclerosis of coronary artery bypass graft(s), unspecified, with angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.70 – Atherosclerosis of coronary artery bypass graft(s), unspecified, with angina pectoris
What it is
This code identifies atherosclerotic narrowing or blockage in a coronary bypass graft, with angina pectoris documented. Use it when the graft vessel is not further specified and chest pain from ischemia is present.
Clinical signs
Typical documentation includes coronary artery disease in a bypass graft and angina, such as exertional chest discomfort or ischemic chest pain. Clinical features vary; refer to documentation.
When to use this code
Use I25.70 when the provider documents atherosclerosis affecting a coronary bypass graft and also states angina pectoris. It applies even if the graft type is not specified, as long as the condition is clearly linked. If the record only says graft disease without angina, check documentation.
Do not use for
Do not use this code for native coronary artery disease without bypass graft involvement. Do not use it if angina is absent or if the chart describes another graft complication, such as occlusion or failure, without atherosclerosis.
Coding tip
Confirm both the bypass graft site and the angina diagnosis are documented before assigning I25.70.
