Cerebral infarction due to embolism of left middle cerebral artery
ICD-10 I63.412 is a billable code used to indicate a diagnosis of cerebral infarction due to embolism of left middle cerebral artery.
Cerebral infarction due to embolism of the left middle cerebral artery (MCA) is a critical condition characterized by the obstruction of blood flow to the brain, specifically affecting the left MCA territory. Clinically, patients may present with sudden onset of neurological deficits, including contralateral hemiparesis, sensory loss, and aphasia, depending on the extent of the infarction. The left MCA supplies a significant portion of the lateral aspect of the cerebral hemisphere, and its occlusion can lead to severe functional impairments. The disease progression can vary; some patients may experience transient ischemic attacks (TIAs) prior to a full-blown stroke, while others may have a rapid decline. Diagnostic considerations include neuroimaging techniques such as CT or MRI to confirm the presence of an infarct and to rule out hemorrhagic stroke. Additionally, identifying the source of the embolism, which may be cardiac (e.g., atrial fibrillation) or from atherosclerotic plaques, is crucial for management and prevention of future strokes.

I63.412 specifically covers cerebral infarction due to embolism affecting the left middle cerebral artery. This includes ischemic strokes resulting from embolic events originating from cardiac sources or other vascular conditions.
I63.412 should be used when the cerebral infarction is confirmed to be due to embolism affecting the left MCA. It is important to differentiate it from other codes that may pertain to right-sided strokes or other types of cerebral infarctions.
Documentation should include clinical notes detailing the patient's symptoms, results from neuroimaging studies confirming the infarction, and any relevant laboratory findings that indicate the source of the embolism.
