Cerebral infarction due to embolism of r verteb art

This code signifies a stroke resulting from a blockage in the right vertebral artery, caused by an embolus (a traveling clot or other foreign material). This type of infarction leads to tissue death in the brain regions supplied by this specific artery.

Apply this code when documentation explicitly states an ischemic stroke due to an embolic event affecting the right vertebral artery. This diagnosis is typically supported by imaging studies (e.g., MRI, CT angiography) confirming the infarction and the specific vessel involvement, along with clinical signs and symptoms consistent with a posterior circulation stroke.

• Ensure documentation specifies "right" vertebral artery; otherwise, an unspecified laterality code may be more appropriate.
• Distinguish from thrombotic occlusions; this code is specifically for embolic causes.
• Always sequence the stroke code first, followed by any associated conditions or sequelae.
