ICD-10 Code I67.2 – Cerebral atherosclerosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I67.2 – Cerebral atherosclerosis
What it is
Cerebral atherosclerosis means atherosclerotic plaque has developed in the arteries supplying the brain. You use this code when the record identifies narrowing or hardening of these vessels without a more specific stroke or infarction code.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include evidence of cerebral arterial narrowing on imaging, prior transient ischemic symptoms, or cerebrovascular disease attributed to atherosclerotic change.
When to use this code
Use I67.2 when the provider documents cerebral atherosclerosis as the diagnosis or as the cause of cerebrovascular disease. It fits cases where the condition is established but no acute infarction, hemorrhage, or more specific cerebrovascular code is documented. Check documentation if the record only says “arteriosclerosis” or “vascular disease” without a cerebral site.
Do not use for
Do not use this code for acute stroke, cerebral infarction, or hemorrhage. Also avoid it when the atherosclerosis is documented in another vascular bed, such as carotid, coronary, or peripheral arteries.
Coding tip
Code the cerebral site only when the provider clearly links atherosclerosis to the brain vessels; otherwise, check documentation.
