Cerebral infarction due to unspecified occlusion or stenosis of basilar artery
ICD-10 I63.22 is a billable code used to indicate a diagnosis of cerebral infarction due to unspecified occlusion or stenosis of basilar artery.
Cerebral infarction due to unspecified occlusion or stenosis of the basilar artery occurs when blood flow to the brain is obstructed, leading to tissue death in the affected area. The basilar artery, formed by the union of the two vertebral arteries, supplies blood to the brainstem, cerebellum, and posterior cerebral hemispheres. Clinical presentation may include sudden onset of neurological deficits such as weakness, speech difficulties, dizziness, or loss of coordination, depending on the area of the brain affected. Disease progression can vary; some patients may experience transient ischemic attacks (TIAs) before a full-blown infarction, while others may have a sudden event. Diagnostic considerations include neuroimaging studies such as CT or MRI to visualize the infarct and assess for occlusion or stenosis. Additionally, vascular imaging like MRA or CTA may be employed to evaluate the basilar artery's patency. Understanding the underlying cause of the occlusion or stenosis is crucial for effective management and prevention of future strokes.

I63.22 covers cerebral infarctions resulting from unspecified occlusions or stenosis of the basilar artery, which may include thrombotic events or embolic strokes where the exact cause is not identified.
I63.22 should be used when the occlusion or stenosis of the basilar artery is confirmed but not specified as thrombotic or embolic. If the cause is known, related codes like I63.21 or I63.23 should be selected.
Documentation should include imaging results showing the infarction and any notes indicating the clinical presentation and assessment of the basilar artery's condition.
