ICD-10 Code I63.8 – Other cerebral infarction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I63.8 – Other cerebral infarction
What it is
I63.8 identifies a cerebral infarction, or stroke, that affects brain tissue but does not fit a more specific infarction category. Use it when documentation clearly states an other cerebral infarction diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common stroke findings may include sudden weakness, speech difficulty, facial droop, visual changes, or altered coordination, depending on the brain area involved.
When to use this code
Use this code when the provider documents an ischemic infarction of the brain and does not name a more specific cerebral infarction type. It is appropriate for finalized diagnoses after evaluation, imaging, or specialist review. Check documentation if the record uses vague terms such as “stroke” or “CVA” without infarction detail.
Do not use for
Do not use this code for hemorrhagic stroke, transient ischemic attack, or cerebral infarction with a more specific ICD-10-CM option. If the chart documents another defined infarction subtype, code that instead.
Coding tip
Verify the provider’s final wording and code the most specific infarction diagnosis documented.
