ICD-10 Code I63.54 – Cerebral infarction due to unspecified occlusion or stenosis of cerebellar artery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I63.54 – Cerebral infarction due to unspecified occlusion or stenosis of cerebellar artery
What it is
This code identifies an ischemic stroke caused by reduced blood flow in a cerebellar artery, with the occlusion or stenosis not otherwise specified. It applies when the infarction is in the cerebellum and the vessel detail is limited.
Clinical signs
Clinical features vary; refer to documentation. Common findings in cerebellar infarction include sudden dizziness, gait imbalance, vertigo, nausea, vomiting, and coordination problems.
When to use this code
Use I63.54 when the provider documents cerebral infarction in a cerebellar artery territory and does not specify the artery beyond “cerebellar artery” or “unspecified occlusion or stenosis.” Confirm that the event is an acute infarction, not a history of stroke or a transient ischemic attack. If the record names a different posterior circulation vessel, check documentation.
Do not use for
Do not use this code for hemorrhagic stroke, TIA, or old infarction without current acute stroke documentation. Check documentation if the chart specifies a more exact artery or a non-cerebellar vascular territory.
Coding tip
Code the infarction only when the provider links the stroke to the cerebellar artery lesion and the specificity remains unspecified.
