Cerebral infarction due to thrombosis of bilateral posterior cerebral arteries
ICD-10 I63.333 is a billable code used to indicate a diagnosis of cerebral infarction due to thrombosis of bilateral posterior cerebral arteries.
Cerebral infarction due to thrombosis of bilateral posterior cerebral arteries is a critical condition characterized by the obstruction of blood flow to the posterior cerebral arteries, resulting in ischemia and subsequent infarction of brain tissue. Clinically, patients may present with symptoms such as visual disturbances, memory deficits, and sensory loss, depending on the extent and location of the infarction. The posterior cerebral arteries supply blood to the occipital lobe and the inferior part of the temporal lobe, making them crucial for visual processing and memory functions. Disease progression can lead to significant neurological deficits and complications such as seizures or cognitive decline. Diagnostic considerations include neuroimaging studies like CT or MRI, which can reveal areas of infarction, as well as vascular imaging to assess for thrombosis. Early recognition and intervention are vital to minimize long-term disability and improve outcomes.

I63.333 specifically covers cerebral infarction resulting from thrombosis affecting both posterior cerebral arteries. This includes ischemic strokes that lead to neurological deficits associated with the areas supplied by these arteries.
I63.333 should be used when there is confirmed thrombosis of both posterior cerebral arteries, as opposed to unilateral involvement, which would be coded with I63.331 or I63.332. Accurate imaging and clinical findings are essential for differentiation.
Documentation should include imaging studies (CT or MRI) showing bilateral infarction, clinical notes detailing symptoms and neurological examination findings, and any relevant laboratory results that support the diagnosis of thrombosis.
