Middle cerebral artery syndrome
ICD-10 G46.0 is a billable code used to indicate a diagnosis of middle cerebral artery syndrome.
Middle cerebral artery syndrome (MCAS) refers to a constellation of neurological deficits resulting from ischemia or infarction in the territory supplied by the middle cerebral artery (MCA). This syndrome is characterized by contralateral hemiparesis, sensory loss, and aphasia, depending on the hemisphere affected. The MCA supplies a significant portion of the lateral cerebral cortex, and occlusion can lead to various clinical manifestations, including motor and sensory deficits, visual field cuts, and cognitive impairments. Transient ischemic attacks (TIAs) may precede a full-blown stroke, presenting as temporary neurological deficits that resolve within 24 hours. Understanding the risk factors for cerebrovascular disease, such as hypertension, diabetes, and hyperlipidemia, is crucial for stroke prevention. Effective management includes lifestyle modifications, antiplatelet therapy, and, in some cases, surgical interventions. Accurate coding of MCAS is essential for appropriate treatment planning and reimbursement, as it reflects the severity and complexity of the patient's condition.
Detailed neurological examination findings, imaging results, and treatment plans.
Patients presenting with acute onset of weakness, speech difficulties, or sensory loss.
Ensure documentation reflects the time course of symptoms and any interventions performed.
Initial assessment findings, vital signs, and any immediate interventions or imaging performed.
Patients presenting with stroke-like symptoms requiring rapid assessment and intervention.
Document the onset of symptoms accurately to determine eligibility for thrombolytic therapy.
Used to evaluate for acute stroke in patients presenting with neurological deficits.
Document the reason for the CT scan and any findings related to stroke.
Neurologists may require additional imaging studies based on initial findings.
Common symptoms include contralateral hemiparesis, sensory loss, aphasia, and visual field deficits, depending on the hemisphere affected.
