Occlusion and stenosis of left vertebral artery
ICD-10 I65.02 is a billable code used to indicate a diagnosis of occlusion and stenosis of left vertebral artery.
I65.02 refers to the occlusion and stenosis of the left vertebral artery, a critical component of the vertebrobasilar circulation that supplies blood to the posterior part of the brain. Clinically, patients may present with symptoms such as dizziness, vertigo, visual disturbances, or even transient ischemic attacks (TIAs) due to compromised blood flow. The anatomy involved includes the left vertebral artery, which branches from the subclavian artery and ascends through the cervical vertebrae to join the basilar artery. Disease progression can lead to significant neurological deficits if not addressed, as chronic occlusion may result in brain ischemia or stroke. Diagnostic considerations include imaging studies such as Doppler ultrasound, CT angiography, or MR angiography to assess blood flow and identify the extent of stenosis or occlusion. Early detection and management are crucial to prevent severe complications, making awareness of this condition vital for healthcare providers.

I65.02 covers conditions related to occlusion and stenosis of the left vertebral artery, which may include vertebral artery dissection, atherosclerosis, and other vascular anomalies that lead to reduced blood flow and potential ischemic events.
I65.02 should be used when specifically diagnosing occlusion or stenosis of the left vertebral artery. It is crucial to differentiate from I65.01 (right vertebral artery) and I65.03 (bilateral vertebral artery) based on imaging and clinical findings.
Documentation should include imaging results that confirm occlusion or stenosis of the left vertebral artery, clinical notes detailing symptoms, and any relevant history of vascular disease or risk factors.
