ICD-10 Code I25.709 – Atherosclerosis of coronary artery bypass graft(s), unspecified, with unspecified angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.709 – Atherosclerosis of coronary artery bypass graft(s), unspecified, with unspecified angina pectoris
What it is
This code identifies atherosclerotic narrowing in a coronary bypass graft, with angina documented but not further specified. Use it when the graft disease is the focus and the angina type is not detailed.
Clinical signs
Clinical features vary; refer to documentation. Common findings include chest discomfort or ischemic symptoms in a patient with prior coronary artery bypass grafting, with evidence of graft atherosclerosis and recorded angina.
When to use this code
Use this code when the provider documents atherosclerosis affecting a coronary bypass graft and specifies angina, but does not identify stable, unstable, or other angina type. It applies to bypass graft disease rather than native coronary artery disease. If the record is unclear, check documentation.
Do not use for
Do not use this code for atherosclerosis of native coronary arteries, or when the angina type is documented more specifically. If graft disease is absent or uncertain, check documentation.
Coding tip
Code the bypass graft condition first, and confirm that the angina is documented as unspecified before selecting I25.709.
