Vertebral artery compression syndromes, cervical region

This code signifies a condition where the vertebral artery, located in the cervical spine, is compressed, leading to symptoms of vertebrobasilar insufficiency. This compression can result from various anatomical factors, such as osteophytes, disc herniation, or muscle spasms, impeding blood flow to the brainstem and cerebellum.

Use this code when documentation clearly indicates a diagnosis of vertebral artery compression syndrome specifically affecting the cervical region. This diagnosis is typically supported by imaging studies (e.g., MRI, MRA, Doppler ultrasound) demonstrating arterial narrowing or occlusion, coupled with clinical signs and symptoms consistent with vertebrobasilar insufficiency (e.g., dizziness, vertigo, syncope, ataxia).

• Ensure the documentation specifies the cervical region for accurate code assignment.
• Distinguish from other causes of vertebrobasilar insufficiency not directly related to vertebral artery compression.
• Consider co-reporting with codes for underlying conditions causing the compression, such as cervical spondylosis (M47.xx) or disc disorders (M50.xx).
