ICD-10 Code I25.812 – Atherosclerosis of bypass graft of coronary artery of transplanted heart without angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.812 – Atherosclerosis of bypass graft of coronary artery of transplanted heart without angina pectoris
What it is
This code identifies atherosclerotic narrowing in a bypass graft supplying the coronary artery of a transplanted heart, without documented angina. Use it when the graft disease is the stated diagnosis and chest pain is not part of the record.
Clinical signs
Clinical features vary; refer to documentation. Findings may include evidence of graft atherosclerosis on cardiac evaluation, with or without ischemic changes, but no angina pectoris is documented.
When to use this code
Use I25.812 when the provider documents atherosclerosis affecting a coronary bypass graft in a transplanted heart and specifically notes no angina. It is appropriate for follow-up visits, specialist assessments, or discharge diagnoses describing graft disease in a transplant recipient. If the chart does not clearly identify the graft location or transplant status, check documentation.
Do not use for
Do not use this code for angina, acute coronary syndrome, or atherosclerosis in a native coronary artery. Check documentation if the record describes graft disease without transplant status or with angina present.
Coding tip
Verify both transplant status and the absence of angina before assigning I25.812.
