ICD-10 Code I25.75 – Atherosclerosis of native coronary artery of transplanted heart with angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.75 – Atherosclerosis of native coronary artery of transplanted heart with angina pectoris
What it is
This code identifies atherosclerotic narrowing in the native coronary arteries of a transplanted heart, with angina pectoris present. Use it when the record clearly links coronary artery disease in the transplanted heart to angina.
Clinical signs
Typical findings include chest pain or pressure consistent with angina, often triggered by exertion or stress. Documentation may also note ischemic symptoms, abnormal cardiac testing, or coronary artery disease affecting the transplanted heart.
When to use this code
Use this code when the provider documents atherosclerosis of the native coronary artery in a transplanted heart and specifies angina pectoris. It fits encounters for evaluation, monitoring, or follow-up of this documented condition. If the chart does not identify angina, check documentation.
Do not use for
Do not use it for angina without documented atherosclerosis, or for coronary disease in a non-transplanted heart. If the note only says graft disease, transplant rejection, or unspecified chest pain, code the documented condition instead.
Coding tip
Confirm both elements are documented: transplanted heart native coronary atherosclerosis and angina pectoris.
