ICD-10 Code I25.7 – Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.7 – Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris
What it is
This code identifies atherosclerotic narrowing in a coronary bypass graft or in the coronary artery of a transplanted heart, with angina pectoris present. It reflects ischemic chest pain linked to graft or transplant vessel disease.
Clinical signs
Typical findings include exertional or rest angina, chest pressure, or other ischemic symptoms documented by the provider. Clinical features vary; refer to documentation for evidence of graft or transplanted-heart coronary involvement.
When to use this code
Use this code when the record clearly states atherosclerosis affecting a coronary bypass graft or the coronary artery of a transplanted heart and angina pectoris is documented. Apply it for current encounters, not historical graft disease alone.
If the note only says coronary artery disease after bypass or transplant without angina, check documentation for the correct more specific code. Verify whether the provider links the angina to the graft or transplanted heart disease.
Do not use for
Do not use this code for angina without documented atherosclerosis of a bypass graft or transplanted coronary artery. Do not assign it when the condition is limited to native coronary arteries or when documentation is unclear.
Coding tip
Confirm both elements: the graft or transplanted-heart vessel disease and the angina pectoris, before assigning I25.7.
