ICD-10 Code I25.810 – Atherosclerosis of coronary artery bypass graft(s) without angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.810 – Atherosclerosis of coronary artery bypass graft(s) without angina pectoris
What it is
This code identifies atherosclerotic narrowing or plaque buildup in a coronary artery bypass graft, without documented angina pectoris. Use it when the provider specifies graft disease and does not report chest pain from ischemia.
Clinical signs
Clinical features vary; refer to documentation. Findings may include evidence of graft atherosclerosis on cardiac testing, angiography, or operative history, with no recorded angina symptoms.
When to use this code
Use this code when the record clearly states atherosclerosis of a coronary bypass graft and the patient does not have angina pectoris documented. It is appropriate for follow-up visits, cardiology notes, or imaging reports that identify graft disease. If the note is unclear about symptoms, check documentation.
Do not use for
Do not use this code if angina pectoris is documented, or if the condition involves native coronary arteries instead of a bypass graft. Check documentation when the graft location or symptom status is uncertain.
Coding tip
Code the bypass graft finding exactly as documented and confirm that angina is absent before assigning I25.810.
