2025 ICD-10-CM code I63.1

Cerebral infarction due to embolism of precerebral arteries. This condition occurs when a blood clot blocks one of the arteries in the neck that supply blood to the brain, resulting in damage to the brain tissue.
Medical necessity is established by the presence of acute neurological deficits due to the blockage of a precerebral artery by an embolus.Treatment is directed at restoring blood flow, minimizing brain damage, and managing any underlying conditions that contributed to the embolism.
Diagnosis and management typically fall under neurology.Other specialists may be involved depending on the patient's specific needs and complications.
In simple words: A stroke caused by a blood clot blocking an artery in the neck, cutting off blood flow to a part of the brain.
Cerebral infarction due to embolism of precerebral arteries.A blood clot (embolus) originating elsewhere in the body travels to and blocks one of the precerebral arteries (such as the carotid, basilar, or vertebral arteries) that supply blood to the brain. This blockage leads to a reduction in blood flow, causing tissue damage in the affected area of the brain.
Example 1: A patient presents with sudden onset of right-sided weakness and difficulty speaking. Imaging reveals a blockage in the left internal carotid artery due to an embolus, confirming a diagnosis of cerebral infarction due to embolism of a precerebral artery., A patient with atrial fibrillation experiences a sudden loss of consciousness.Subsequent examination and imaging show evidence of an embolus blocking the basilar artery, leading to cerebral infarction., A patient undergoing a carotid artery stent procedure experiences an embolic event, resulting in a cerebral infarction. This complication highlights the risk of embolism during vascular interventions.
Documentation should include details of the neurological examination, imaging findings (e.g., CT, MRI), evidence of embolism (e.g., cardiac source), and any associated risk factors (e.g., atrial fibrillation, hypercoagulable state).
** Consider using additional codes to document the NIH Stroke Scale (NIHSS) score (R29.7-) which quantifies stroke severity.
