ICD-10 Code I63.411 – Cerebral infarction due to embolism of right middle cerebral artery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I63.411 – Cerebral infarction due to embolism of right middle cerebral artery
What it is
This code identifies an ischemic stroke caused by an embolus blocking the right middle cerebral artery. Use it when documentation specifies cerebral infarction from embolism in that artery.
Clinical signs
Typical findings include sudden focal neurologic deficits such as left-sided weakness, sensory loss, facial droop, speech disturbance, or visual changes. Clinical features vary; refer to documentation.
When to use this code
Use I63.411 when the provider documents cerebral infarction due to embolism affecting the right middle cerebral artery. It may appear in acute stroke, discharge, or follow-up documentation when the infarct location and embolic cause are both stated. If the record only says “stroke” or “CVA,” check documentation.
Do not use for
Do not use this code for hemorrhagic stroke, transient ischemic attack, or infarction from thrombosis without embolism. Check documentation if the affected artery or cause is not clearly specified.
Coding tip
Code the embolic mechanism and laterality only when both are documented; otherwise, query for clarification.
