Occlusion and stenosis of vertebral artery
ICD-10 I65.0 is a used to indicate a diagnosis of occlusion and stenosis of vertebral artery.
I65.0 refers to the occlusion and stenosis of the vertebral artery, which is a critical component of the vertebrobasilar circulation supplying blood to the posterior part of the brain. Clinically, patients may present with symptoms such as dizziness, vertigo, visual disturbances, and in severe cases, posterior circulation strokes. The vertebral arteries arise from the subclavian arteries and ascend through the cervical vertebrae, merging to form the basilar artery. Disease progression can lead to significant ischemic events, particularly in older adults or those with risk factors like hypertension, diabetes, and hyperlipidemia. Diagnostic considerations include imaging studies such as Doppler ultrasound, CT angiography, or MR angiography to assess blood flow and identify stenosis or occlusion. Early detection and management are crucial to prevent complications such as transient ischemic attacks (TIAs) or strokes.

I65.0 covers occlusion and stenosis of the vertebral artery, which may lead to ischemic symptoms and complications such as strokes. It is important to differentiate it from other cerebrovascular conditions.
I65.0 should be used when there is a confirmed diagnosis of vertebral artery occlusion or stenosis, particularly when imaging studies support this finding, differentiating it from codes for other vascular territories.
Documentation should include a comprehensive clinical evaluation, imaging results showing occlusion or stenosis of the vertebral artery, and any relevant patient history that supports the diagnosis.
