Cerebral infarction due to thrombosis of left posterior cerebral artery
ICD-10 I63.332 is a billable code used to indicate a diagnosis of cerebral infarction due to thrombosis of left posterior cerebral artery.
Cerebral infarction due to thrombosis of the left posterior cerebral artery is a type of ischemic stroke that occurs when a blood clot obstructs blood flow to the left posterior cerebral artery (PCA), 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 cognitive deficits, including memory loss or difficulty with spatial awareness. The anatomy involved includes the left PCA, which branches from the basilar artery and is crucial for supplying oxygenated blood to the brain regions responsible for visual processing and higher cognitive functions. Disease progression can vary; some patients may experience rapid onset of symptoms, while others may have a more gradual presentation. Diagnostic considerations include neuroimaging techniques such as CT or MRI to confirm the presence of an infarct and to rule out hemorrhagic stroke. Early recognition and intervention are critical to minimize neurological damage and improve patient outcomes.

I63.332 specifically covers cerebral infarction resulting from thrombosis of the left posterior cerebral artery, which may lead to visual and cognitive impairments. It is crucial to differentiate this from other types of strokes and infarctions.
I63.332 should be used when the infarction is specifically due to thrombosis of the left PCA, as opposed to other arteries or causes of stroke. Accurate diagnosis and imaging findings are essential for appropriate code selection.
Documentation should include clinical notes detailing the patient's symptoms, results from neuroimaging studies confirming the infarction, and any relevant medical history that supports the diagnosis of thrombosis of the left PCA.
