Cerebral infarction due to unspecified occlusion or stenosis of left posterior cerebral artery
ICD-10 I63.532 is a billable code used to indicate a diagnosis of cerebral infarction due to unspecified occlusion or stenosis of left posterior cerebral artery.
Cerebral infarction due to unspecified occlusion or stenosis of the left posterior cerebral artery (PCA) occurs when blood flow to the PCA is interrupted, leading to ischemia and subsequent tissue death in the areas supplied by this artery. Clinically, patients may present with visual disturbances, sensory deficits, or cognitive impairments, depending on the extent and location of the infarction. The PCA supplies blood to the occipital lobe, inferior temporal lobe, and parts of the thalamus, making its occlusion particularly impactful on visual processing and spatial awareness. Disease progression can vary; some patients may experience rapid deterioration, while others may have a more gradual onset of symptoms. Diagnostic considerations include neuroimaging techniques such as MRI or CT scans to confirm the presence of an infarct and to rule out other potential causes of neurological deficits. Additionally, vascular imaging may be necessary to identify the specific occlusion or stenosis affecting the PCA. Early diagnosis and intervention are crucial to minimize long-term neurological deficits and improve patient outcomes.

I63.532 covers cerebral infarctions resulting from unspecified occlusions or stenosis of the left posterior cerebral artery. This includes ischemic strokes where the exact cause of the occlusion is not clearly defined, necessitating further investigation.
I63.532 should be used when the occlusion or stenosis of the left PCA is confirmed but not specified. If the occlusion type is known (e.g., embolic or thrombotic), a more specific code should be selected.
Documentation must include clinical findings, imaging results confirming the cerebral infarction, and any relevant patient history that supports the diagnosis of occlusion or stenosis of the left PCA.
