Cerebral infrc due to embolism of left post cerebral artery

This code signifies an ischemic stroke affecting the left posterior cerebral artery, caused by a blockage from an embolus (a traveling clot or other material). This results in tissue death (infarction) in the brain region supplied by this specific artery.

Use this code when documentation clearly indicates an acute cerebral infarction in the left posterior cerebral artery territory, with the etiology specified as embolic. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) confirming the infarction and clinical findings consistent with posterior cerebral artery stroke.

• Ensure the documentation specifies "left" posterior cerebral artery and "embolism" as the cause.
• Distinguish from thrombotic strokes (I63.3x) or strokes of unspecified etiology (I63.9).
• Always sequence this code first if it represents the acute condition for which the patient is being treated.
