Cerebral infarction due to unspecified occlusion or stenosis of bilateral posterior cerebral arteries
ICD-10 I63.533 is a billable code used to indicate a diagnosis of cerebral infarction due to unspecified occlusion or stenosis of bilateral posterior cerebral arteries.
I63.533 refers to cerebral infarction due to unspecified occlusion or stenosis of bilateral posterior cerebral arteries. This condition arises when blood flow to the posterior cerebral arteries, which supply blood to the occipital lobe and parts of the temporal lobe, is obstructed. Clinical presentation may include visual disturbances, such as homonymous hemianopia, and cognitive deficits due to the involvement of areas responsible for processing visual information and memory. The disease progression can vary; some patients may experience sudden onset of symptoms, while others may have transient ischemic attacks (TIAs) before a full-blown infarction occurs. Diagnostic considerations include neuroimaging techniques such as MRI or CT scans to identify areas of infarction and assess the extent of occlusion or stenosis. Additionally, vascular imaging may be necessary to evaluate the underlying causes, such as atherosclerosis or embolism, contributing to the occlusion of these arteries.

I63.533 covers cerebral infarctions resulting from unspecified occlusion or stenosis of the bilateral posterior cerebral arteries, which may include ischemic strokes and related neurological deficits.
I63.533 should be used when the occlusion or stenosis is bilateral and unspecified, differentiating it from codes that specify unilateral involvement or other types of strokes.
Documentation should include clinical findings, imaging results showing infarction, and notes on the patient's neurological status and any risk factors contributing to the condition.
