ICD-10 Code I67.9 – Cerebrovascular disease, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I67.9 – Cerebrovascular disease, unspecified
What it is
I67.9 identifies a cerebrovascular disorder affecting the brain’s blood vessels when the specific condition is not documented. Use it for a nonspecific vascular brain disease, not for an acute stroke or hemorrhage.
Clinical signs
Clinical features vary; refer to documentation. Patients may have neurologic symptoms related to chronic or unspecified cerebrovascular disease, but the record should support a vascular brain disorder rather than another neurologic diagnosis.
When to use this code
Use I67.9 when the provider documents cerebrovascular disease without naming the exact type, such as when the chart says “cerebrovascular disease” or “unspecified cerebrovascular disorder.” It is appropriate when the condition is not further classified in the note. If the documentation identifies a more specific cerebrovascular diagnosis, code that instead.
Do not use for
Do not use this code for acute stroke, transient ischemic attack, or intracranial hemorrhage. If the record specifies a different cerebrovascular condition, choose the documented diagnosis.
Coding tip
Query for specificity whenever the provider documents only “cerebrovascular disease” and the record may support a more precise code.
