FY2007 Added to the draft code set draft Cerebral infarction due to unspecified occlusion or stenosis of left vertebral arteries
FY2018 Description revised ~~Cerebral infarction due to unspecified occlusion or stenosis of left vertebral arteries~~ Cerebral infarction due to unspecified occlusion or stenosis of left vertebral artery
