ICD-10 Code I67 – Other cerebrovascular diseases (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I67 – Other cerebrovascular diseases
What it is
I67 covers cerebrovascular conditions that affect the brain’s blood vessels but are not classified elsewhere. Use it when documentation names a specific “other” vascular disorder of the brain and no more specific code applies.
Clinical signs
Clinical features vary; refer to documentation. Patients may have neurologic symptoms related to abnormal cerebral blood flow or vessel disease, such as headache, focal deficits, or prior stroke-related findings.
When to use this code
Use I67 when the provider documents an unspecified or other cerebrovascular disorder that does not fit a more specific category. It may appear in follow-up care, problem lists, or imaging-based assessments. If the record identifies a more specific diagnosis, code that instead.
Do not use for
Do not use I67 for acute stroke, transient ischemic attack, or traumatic vascular injury. Also avoid it when the chart supports a more specific cerebrovascular code.
Coding tip
Check the full assessment for the exact vascular diagnosis before assigning I67.
