ICD-10 Code I25.811 – Atherosclerosis of native coronary artery of transplanted heart without angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.811 – Atherosclerosis of native coronary artery of transplanted heart without angina pectoris
What it is
This code identifies atherosclerotic narrowing in the native coronary arteries of a transplanted heart, without documented angina. Use it when the record specifies coronary artery disease in the transplanted heart and does not mention chest pain.
Clinical signs
Clinical features vary; refer to documentation. Findings may include evidence of coronary atherosclerosis on imaging, angiography, or transplant follow-up notes, with no angina reported.
When to use this code
Use I25.811 when the provider documents atherosclerosis affecting the native coronary arteries in a transplanted heart and explicitly states there is no angina pectoris. It is appropriate for transplant cardiology follow-up, problem lists, or assessment notes that confirm the diagnosis.
Code it only when the condition is clearly documented. If the note mentions coronary disease but does not specify transplanted heart involvement or angina status, check documentation.
Do not use for
Do not use this code for angina without documented atherosclerosis, or for coronary disease in a non-transplanted heart. Do not assign it when the record is unclear about the transplant status or native coronary involvement.
Coding tip
Verify both elements: transplanted heart and absence of angina; if either is missing, query the provider.
