ICD-10 Code I25.118 – Atherosclerotic heart disease of native coronary artery with other forms of angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.118 – Atherosclerotic heart disease of native coronary artery with other forms of angina pectoris
What it is
This code identifies coronary artery disease in a native coronary artery with angina that is not described as unstable or due to spasm. Use it when the record clearly links atherosclerotic heart disease to another specified form of angina pectoris.
Clinical signs
Typical findings include chest discomfort or pressure related to myocardial ischemia, often triggered by exertion or stress. Clinical features vary; refer to documentation for the exact angina type and whether the coronary disease is documented as atherosclerotic.
When to use this code
Use this code when the provider documents native coronary artery atherosclerosis with angina pectoris and specifies a form other than unstable or vasospastic angina. It is appropriate for outpatient, inpatient, or problem-list documentation when the diagnosis is confirmed in the chart. Check documentation if the angina type is unclear.
Do not use for
Do not use it for unstable angina, coronary spasm, or angina not linked to atherosclerotic native coronary artery disease. If the record only says chest pain without a confirmed diagnosis, code the symptom instead.
Coding tip
Look for both the coronary artery disease and the specific angina type in the provider’s documentation before assigning I25.118.
