Occlusion and stenosis of right vertebral artery
ICD-10 I65.01 is a billable code used to indicate a diagnosis of occlusion and stenosis of right vertebral artery.
I65.01 refers to the occlusion and stenosis of the right vertebral artery, a critical vessel supplying blood to the posterior circulation of the brain. Clinically, patients may present with symptoms such as dizziness, vertigo, visual disturbances, or even signs of posterior circulation stroke, including ataxia or altered consciousness. The vertebral arteries originate from the subclavian arteries and ascend through the cervical vertebrae, merging to form the basilar artery. Disease progression can lead to significant ischemic events if blood flow is compromised. Diagnostic considerations include imaging studies such as Doppler ultrasound, CT angiography, or MRI to assess blood flow and identify stenosis or occlusion. Risk factors include atherosclerosis, hypertension, and diabetes, which can contribute to vascular changes over time. Early detection and management are crucial to prevent severe neurological deficits.

I65.01 covers occlusion and stenosis specifically of the right vertebral artery, which may lead to ischemic events affecting the brain's posterior circulation. It is important to differentiate this from occlusions in other arteries or bilateral involvement.
I65.01 should be used when there is a confirmed diagnosis of occlusion or stenosis of the right vertebral artery, particularly when imaging studies support this finding. It should be differentiated from codes for left-sided or bilateral conditions.
Documentation should include clinical findings, imaging results confirming occlusion or stenosis of the right vertebral artery, and any relevant patient history that supports the diagnosis, such as risk factors and presenting symptoms.
