ICD-10 Code I67.82 – Cerebral ischemia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I67.82 – Cerebral ischemia
What it is
I67.82 identifies cerebral ischemia, meaning reduced blood flow to the brain. Use it when documentation describes ischemia affecting brain tissue without a more specific stroke or infarction diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note transient neurologic deficits, altered speech, weakness, numbness, or other signs of brain hypoperfusion.
When to use this code
Use I67.82 when the provider documents cerebral ischemia as the diagnosis and does not specify cerebral infarction, transient ischemic attack, or another more specific cerebrovascular condition. It may apply to imaging or clinical assessments indicating ischemia of the brain. Check documentation if the record is unclear.
Do not use for
Do not use this code for cerebral infarction, stroke, or TIA when those conditions are documented. Do not assign it for nonspecific dizziness or syncope without evidence of cerebral ischemia.
Coding tip
Code the most specific cerebrovascular diagnosis documented; if the note only says “ischemia,” confirm it refers to the brain before assigning I67.82.
