ICD-10 Code I25.769 – Atherosclerosis of bypass graft of coronary artery of transplanted heart with unspecified angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.769 – Atherosclerosis of bypass graft of coronary artery of transplanted heart with unspecified angina pectoris
What it is
This code identifies atherosclerotic narrowing in a bypass graft supplying a transplanted heart, with angina documented but not further specified. Use it when the record links the graft disease to the transplant heart and angina is present.
Clinical signs
Typical findings include chest discomfort or other ischemic symptoms in a patient with a transplanted heart and prior coronary bypass grafting. Clinical features vary; refer to documentation for the type of angina and evidence of graft atherosclerosis.
When to use this code
Use this code when the provider documents atherosclerosis affecting a coronary bypass graft in a transplanted heart and the angina is not described as stable, unstable, or another specific type. It fits coded diagnoses tied to the graft, not the native coronary arteries. If the chart does not clearly identify the graft or transplant status, check documentation.
Do not use for
Do not use it for angina without documented graft atherosclerosis, or for coronary disease in a non-transplanted heart. Do not assign it when the record specifies a different angina type or a different vessel location.
Coding tip
Verify both the transplanted-heart status and the bypass graft involvement before assigning I25.769.
