Cerebral infarction due to thrombosis of left middle cerebral artery
ICD-10 I63.312 is a billable code used to indicate a diagnosis of cerebral infarction due to thrombosis of left middle cerebral artery.
Cerebral infarction due to thrombosis of the left middle cerebral artery (MCA) is a critical condition that arises when a thrombus obstructs blood flow in this major cerebral artery, leading to ischemic damage in the corresponding brain regions. Clinically, patients may present with sudden onset of neurological deficits, including contralateral hemiparesis, sensory loss, aphasia, and visual field deficits, depending on the area of the brain affected. The left MCA supplies blood to significant areas involved in language and motor control, which can result in profound functional impairments. 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. Early intervention is crucial to minimize brain damage and improve outcomes, often involving thrombolytic therapy or mechanical thrombectomy if presented within the therapeutic window.

I63.312 specifically covers cerebral infarction due to thrombosis of the left middle cerebral artery, which can manifest as various neurological deficits depending on the extent and location of the infarction.
I63.312 should be used when there is clear documentation of a cerebral infarction specifically due to thrombosis of the left middle cerebral artery, differentiating it from other types of strokes or infarctions.
Documentation should include clinical findings of neurological deficits, imaging results confirming the infarction in the left MCA territory, and treatment details that indicate the acute nature of the event.
