ICD-10 Code I25.702 – Atherosclerosis of coronary artery bypass graft(s), unspecified, with refractory angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.702 – Atherosclerosis of coronary artery bypass graft(s), unspecified, with refractory angina pectoris
What it is
This code identifies atherosclerotic disease in a coronary artery bypass graft when the graft site is not further specified, and the patient has refractory angina pectoris. Use it when documentation links the bypass graft disease to ongoing chest pain that is difficult to control.
Clinical signs
Clinical features may include persistent or recurrent angina despite usual management. Documentation should support coronary bypass graft disease and refractory angina; if details are limited, clinical features vary; refer to documentation.
When to use this code
Use this code when the record states atherosclerosis involves a coronary artery bypass graft and the graft is unspecified. It also requires documentation of refractory angina pectoris, meaning the angina remains present despite treatment or is described as refractory. If the note does not clearly connect both conditions, check documentation.
Do not use for
Do not use this code for native coronary artery disease without bypass graft involvement, or for angina without documentation of refractory status. If the graft site is specified differently or the diagnosis is uncertain, check documentation.
Coding tip
Confirm both the bypass graft atherosclerosis and the refractory angina wording are documented before assigning I25.702.
