I63.02
Cerebral infarction due to thrombosis of basilar artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Cerebral infarction, also known as a stroke, occurs when blood flow to a part of the brain is interrupted, leading to brain cell damage or death. Specifically, the ICD-10 code I63.02 refers to a type of stroke caused by a blood clot (thrombosis) blocking the basilar artery, a major vessel at the base of the brain. This condition can have serious consequences because the basilar artery supplies blood to a large portion of the brain, including regions responsible for vital functions like breathing, consciousness, and movement.
Causes & Symptoms
Clinical Causes: Formation of a blood clot (thrombosis) within the basilar artery Atherosclerosis leading to narrowing of the artery and subsequent clot formation Blood vessel injury or damage that promotes clot development Rarely, emboli (clots formed elsewhere) that travel and lodge in the basilar artery High blood pressure and other cardiovascular risk factors that predispose to clot formation
Key Symptoms: Sudden weakness or paralysis, often affecting the face, arms, or legs Difficulty speaking or understanding speech (aphasia) Loss of coordination or balance, leading to dizziness or vertigo Visual disturbances such as double vision or loss of vision Severe headache suddenly developing Altered consciousness or decreased responsiveness Trouble swallowing and breathing difficulties in severe cases
Diagnostic & Treatment
Diagnosis Path: Neuroimaging studies such as MRI or CT scans to identify areas of brain damage and locate the blocked artery Magnetic resonance angiography (MRA) or CT angiography (CTA) to visualize blood flow and pinpoint the location of the clot Blood tests to evaluate clotting factors and cardiovascular risk markers Neurological assessments to determine the severity and specific deficits based on symptoms
Treatment Protocols: Thrombolytic therapy (clot-busting medications) if administered promptly after symptom onset Mechanical thrombectomy, a procedure to physically remove the clot in certain cases Supportive care including oxygen therapy and stabilization of vital signs Medications to control blood pressure, blood sugar, and cholesterol levels Antiplatelet agents or anticoagulants to prevent further clot formation Rehabilitation therapies, such as physical, occupational, and speech therapy, to recover lost functions

Billing Guidance
Is I63.02 a billable ICD-10 code?
Yes, I63.02 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report I63.02?
Clinical documentation must specify the nature of Cerebral infarction due to thrombosis of basilar artery and any associated comorbidities for accurate reporting.
