ICD-10 Code G46.5 | Pure motor lacunar syndrome Symptoms, Diagnosis, Billing

Common symptoms include sudden weakness in one side of the body, particularly affecting the arm and leg, without sensory loss. Patients may also experience dysarthria or facial weakness.

Diagnosis is typically made through clinical evaluation, including neurological examination and imaging studies such as MRI or CT scans to identify lacunar infarcts.

Treatment focuses on managing risk factors such as hypertension and diabetes, along with rehabilitation therapies like physical and occupational therapy to improve motor function.

Hospitalization may be required for acute management, especially if there are significant neurological deficits or complications that need close monitoring.
