Cerebral infarction due to thrombosis of unspecified posterior cerebral artery
ICD-10 I63.339 is a billable code used to indicate a diagnosis of cerebral infarction due to thrombosis of unspecified posterior cerebral artery.
Cerebral infarction due to thrombosis of the unspecified posterior cerebral artery is a type of ischemic stroke that occurs when a blood clot obstructs blood flow to the posterior cerebral artery, which supplies blood to the occipital lobe and parts of the temporal lobe. Clinically, patients may present with visual disturbances, such as homonymous hemianopia, and other neurological deficits depending on the extent of the infarction. The anatomy involved includes the posterior cerebral artery, which branches from the basilar artery and is crucial for supplying oxygenated blood to vital brain regions. Disease progression can lead to significant neurological impairment, and timely intervention is critical to minimize brain damage. Diagnostic considerations include neuroimaging studies, such as CT or MRI scans, to confirm the presence of an infarct and to rule out hemorrhagic stroke. Additionally, a thorough clinical history and physical examination are essential to assess risk factors such as hypertension, diabetes, and hyperlipidemia, which contribute to thrombosis.

I63.339 covers cerebral infarction due to thrombosis of the unspecified posterior cerebral artery, which may include conditions like ischemic stroke without specific localization or when the exact artery cannot be determined.
I63.339 should be used when the clinical presentation indicates a posterior cerebral artery infarction but the specific artery cannot be identified. If the artery is known, a more specific code should be selected.
Documentation should include imaging results confirming the infarction, a detailed clinical history, and physical examination findings that support the diagnosis of cerebral infarction due to thrombosis.
