ICD-10 Code I63.541 – Cerebral infarction due to unspecified occlusion or stenosis of right cerebellar artery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I63.541 – Cerebral infarction due to unspecified occlusion or stenosis of right cerebellar artery
What it is
This code identifies an ischemic stroke in the right cerebellar artery territory when the cause is an unspecified narrowing or blockage. Use it for a documented cerebellar infarction affecting the right side.
Clinical signs
Clinical features vary; refer to documentation. Common cerebellar stroke findings include dizziness, imbalance, gait ataxia, nausea, vomiting, and limb coordination problems.
When to use this code
Use I63.541 when the record states cerebral infarction due to unspecified occlusion or stenosis of the right cerebellar artery. You should also use it when imaging or specialist documentation localizes the infarct to that artery territory but does not name a specific occlusive cause.
Do not substitute a nonspecific stroke code if the right cerebellar artery is clearly identified. Check documentation for laterality, vessel name, and whether the event is acute or a history of infarction.
Do not use for
Do not use this code for hemorrhagic stroke, transient ischemic attack, or infarction in another vascular territory. Check documentation if the artery is not the right cerebellar artery or if the cause is specified elsewhere.
Coding tip
Confirm both the infarct location and the right-sided cerebellar artery before assigning I63.541.
