Cerebral infarction due to embolism of posterior cerebral artery
ICD-10 I63.43 is a used to indicate a diagnosis of cerebral infarction due to embolism of posterior cerebral artery.
Cerebral infarction due to embolism of the posterior cerebral artery (PCA) is a critical condition characterized by the obstruction of blood flow to the PCA, leading to ischemic damage in the brain. The PCA supplies blood to the occipital lobe, inferior temporal lobe, and various deep structures, including the thalamus. Clinical presentation often includes visual disturbances, such as homonymous hemianopia, and cognitive deficits, depending on the extent of the infarction. The disease progression can vary; some patients may experience rapid onset of symptoms, while others may have a more gradual decline. Diagnostic considerations include neuroimaging techniques such as CT or MRI scans to confirm the presence of an infarct and to rule out hemorrhagic stroke. Additionally, vascular imaging may be performed to identify the source of the embolism, which could be cardiac in origin or due to atherosclerotic disease. Timely diagnosis and intervention are crucial to minimize neurological deficits and improve patient outcomes.

I63.43 specifically covers cerebral infarctions resulting from embolism affecting the posterior cerebral artery. This includes emboli from cardiac sources, such as atrial fibrillation, or from other vascular conditions.
I63.43 should be used when the cerebral infarction is confirmed to be due to an embolism affecting the PCA. If the infarction is due to thrombosis or affects a different artery, other codes such as I63.41 or I63.42 should be considered.
Documentation must include clinical findings, imaging results confirming the infarction, and evidence of the embolic source. Detailed notes on the patient's history, neurological examination, and treatment plan are also necessary.
