Cerebral infrc due to embolism of bi middle cerebral art

This code signifies a stroke resulting from a blood clot originating elsewhere in the body (e.g., heart) that travels to and obstructs both middle cerebral arteries in the brain. This bilateral obstruction leads to tissue death (infarction) in the areas supplied by these arteries.

Apply this code when documentation clearly states a cerebral infarction caused by an embolism affecting both the left and right middle cerebral arteries. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) confirming bilateral MCA involvement and clinical findings consistent with embolic stroke.

• Ensure documentation specifies "bilateral" involvement of the middle cerebral arteries.
• Distinguish from thrombotic strokes (I63.3x) where the clot originates within the cerebral artery itself.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for any underlying conditions (e.g., atrial fibrillation).
