ICD-10 Code I63.44 – Cerebral infarction due to embolism of cerebellar artery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I63.44 – Cerebral infarction due to embolism of cerebellar artery
What it is
This code identifies an ischemic stroke in the cerebellum caused by an embolus blocking a cerebellar artery. Use it when documentation clearly states cerebral infarction due to embolism of a cerebellar artery.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings in cerebellar stroke include dizziness, gait imbalance, nausea, vomiting, limb incoordination, and slurred speech.
When to use this code
Use I63.44 when the provider documents an acute or current cerebellar infarction caused by embolism. The record should link the infarction to a cerebellar artery and specify an embolic cause. If the artery or cause is not stated, check documentation.
Do not use for
Do not use this code for hemorrhagic stroke, transient ischemic attack, or infarction from thrombosis or unspecified occlusion. If the record only says “stroke” or “cerebral infarction” without embolic cerebellar detail, check documentation.
Coding tip
Confirm both the vascular territory and embolic mechanism before assigning I63.44.
