ICD-10 Code I25.81 – Atherosclerosis of other coronary vessels without angina pectoris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I25.81 – Atherosclerosis of other coronary vessels without angina pectoris
What it is
This code identifies coronary artery atherosclerosis in vessels other than the native coronary arteries, without current angina pectoris. It reflects chronic plaque-related narrowing or obstruction documented by the provider.
Clinical signs
Clinical features vary; refer to documentation. Findings may include known coronary artery disease on imaging, catheterization, or prior cardiac history, but no active chest pain is documented with this diagnosis.
When to use this code
Use this code when the record clearly states atherosclerosis of other coronary vessels and specifically notes absence of angina pectoris. It may apply to follow-up visits, historical disease review, or ongoing management of established coronary disease. Check documentation if the vessel type or angina status is unclear.
Do not use for
Do not use this code for coronary atherosclerosis with angina, or when the chart only describes generalized atherosclerosis without coronary vessel detail. Also avoid it if the provider documents a different coronary diagnosis. Check documentation.
Coding tip
Assign the code only when the provider documents both the coronary vessel atherosclerosis and the absence of angina pectoris.
