ICD-10-CM Code G45.0
Vertebro-basilar artery syndrome

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

G45.0 is a billable ICD code used to specify a diagnosis of vertebro-basilar artery syndrome. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code G450 is used to code Vertebrobasilar insufficiency

Vertebrobasilar insufficiency (VBI), or vertebral basilar ischemia (also called Beauty parlour syndrome (BPS)), refers to a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain. The posterior circulation supplies blood to the medulla, cerebellum, pons, midbrain, thalamus, and occipital cortex (responsible for vision). Therefore, the symptoms due to VBI vary according to which portions of the brain experience significantly decreased blood flow (see image of brain ). In the United States, 25% of strokes and transient ischemic attacks occur in the vertebrobasilar distribution. These must be separated from strokes arising from the anterior circulation, which involves the carotid arteries.
