I63.431
Cerebral infarction due to embolism of right posterior cerebral artery
Clinical Classification Guidelines
Medical Intelligence & Overview
Cerebral infarction, commonly known as a stroke, occurs when blood flow to a part of the brain is blocked, leading to brain cell damage or death. The specific type labeled as I63.431 refers to an infarction caused by an embolism in the right posterior cerebral artery. This artery supplies blood to parts of the occipital lobe, which are primarily responsible for visual processing. When an embolism occludes this artery, it can result in visual deficits and other neurological symptoms affecting the region it supplies.
Causes & Symptoms
Clinical Causes: Blood clots originating from the heart or large arteries, traveling through the bloodstream to block the posterior cerebral artery Atrial fibrillation, which can promote clot formation within the heart Atherosclerosis, leading to narrowing of blood vessels Heart valve disease or conditions that contribute to clot formation Other embolic sources such as fat or air bubbles
Key Symptoms: Visual disturbances such as partial or complete loss of vision in one eye or visual field deficits Weakness or numbness on one side of the body Difficulty with coordination or balance Confusion or difficulty understanding speech Headache, often sudden and severe Possible difficulty speaking or swallowing, depending on infarct size
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves assessing clinical symptoms and confirming through imaging tests such as MRI or CT scans. These imaging techniques help visualize the area of infarction and identify the occluded artery. Additional tests like echocardiography or Doppler ultrasound might be used to evaluate potential embolic sources. Blood tests assess clotting functions and identify risk factors related to stroke.
Treatment Protocols: Thrombolytic therapy (clot-busting medications) if administered within a specific time window Antiplatelet or anticoagulant medications to prevent new clots Blood pressure management to optimize cerebral perfusion Surgical interventions or endarterectomy if significant vessel narrowing is identified Rehabilitation therapies such as physical, occupational, and speech therapy to aid recovery

Yes, I63.431 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report I63.431?
