I63.011
Cerebral infarction due to thrombosis of right vertebral artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Cerebral infarction, commonly known as ischemic stroke, occurs when blood flow to a part of the brain is blocked. The specific type identified by ICD-10 code I63.011 involves a blockage caused by a blood clot (thrombosis) in the right vertebral artery. The vertebral arteries are major vessels that supply blood to critical regions of the brain, including the posterior part of the brain, which affects functions like balance, coordination, and vision. Understanding this condition sheds light on its causes, symptoms, diagnosis, and general approaches to management.
Causes & Symptoms
Clinical Causes: Formation of blood clots (thrombosis) within the right vertebral artery Atherosclerosis leading to narrowing and increased risk of clot development High blood pressure damaging the artery walls Blood vessel abnormalities or injuries Chronic conditions such as diabetes that impair blood vessel health Lifestyle factors including smoking, sedentary behavior, and poor diet Cardiovascular issues such as atrial fibrillation that can lead to clots traveling to brain arteries
Key Symptoms: Dizziness or vertigo Loss of coordination or balance problems Difficulty swallowing or speaking Weakness or numbness on one side of the body Sudden vision loss or double vision Headache, often severe Nausea or vomiting Altered consciousness or confusion in severe cases
Diagnostic & Treatment
Diagnosis Path: Magnetic resonance imaging (MRI) or computed tomography (CT) scans to visualize brain tissue and identify areas of infarction Magnetic resonance angiography (MRA) or CT angiography to assess blood flow in the vertebral arteries Carotid ultrasound to examine nearby arteries for additional blockages Blood tests to identify risk factors such as clotting disorders or high cholesterol levels Electrocardiogram (ECG) to detect cardiac sources of emboli
Treatment Protocols: Thrombolytic therapy with medications to dissolve clots (administered within specific time windows) Antiplatelet drugs such as aspirin to prevent new clot formation Anticoagulants like warfarin or direct oral anticoagulants for patients with specific risk factors Management of underlying conditions such as hypertension, diabetes, and hyperlipidemia Lifestyle modifications including smoking cessation, diet changes, and regular exercise Surgical interventions like endarterectomy or angioplasty in selected cases to remove or widen blockages Rehabilitation therapies, including physical, speech, and occupational therapy, to aid recovery and regain lost functions

Yes, I63.011 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report I63.011?
Clinical documentation must specify the nature of Cerebral infarction due to thrombosis of right vertebral artery and any associated comorbidities for accurate reporting.
