Cerebral infarction due to embolism of bilateral verteb art

This code signifies a cerebral infarction (ischemic stroke) resulting from an embolic event specifically affecting both vertebral arteries. This indicates a blockage of blood flow to the brainstem and posterior circulation due to a clot originating elsewhere in the body.

Use this code when documentation clearly states an ischemic stroke caused by an embolism impacting both vertebral arteries. Supporting documentation should include imaging reports confirming infarction and physician notes specifying the embolic etiology and bilateral vertebral artery involvement.

• Ensure documentation explicitly states "bilateral vertebral arteries" and "embolism" as the cause of infarction.
• Distinguish from thrombotic occlusions of the vertebral arteries, which would be coded differently.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated conditions.
