ICD-10 Code I25.119 – Atherosclerotic heart disease of native coronary artery with unspecified angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.119 – Atherosclerotic heart disease of native coronary artery with unspecified angina pectoris
What it is
This code identifies coronary atherosclerosis in a native coronary artery with angina pectoris, but the angina type is not specified. Use it when the record clearly links ischemic heart disease to chest pain or angina.
Clinical signs
Typical findings include exertional chest discomfort, pressure, or tightness consistent with angina. Clinical features vary; refer to documentation for whether the angina is stable, unstable, or otherwise specified.
When to use this code
Use I25.119 when the provider documents atherosclerotic heart disease of a native coronary artery and angina pectoris, but does not state the angina type. It is appropriate for outpatient, inpatient, and problem-list coding when the diagnosis is established. Check documentation if the record mentions coronary disease without angina.
Do not use for
Do not use this code for angina without documented coronary atherosclerosis, or for coronary disease involving bypass grafts or stents. If the angina type is specified elsewhere, code that more precise option instead.
Coding tip
Look for explicit provider wording that links native coronary artery disease with unspecified angina before assigning I25.119.
