2025 ICD-10-CM code I97.81
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Circulatory System Disorders - Other and unspecified disorders of the circulatory system Diseases of the circulatory system (I00-I99) Feed
Intraoperative cerebrovascular infarction.
Modifiers might be needed to indicate the location of the stroke and additional factors.
The medical necessity is established by the documentation of the intraoperative stroke. The clinical indication for the procedure that led to the stroke should be clearly outlined and medically justifiable, demonstrating that the procedure was necessary.The appropriate level of care was rendered and documented in the record. Documentation should demonstrate adherence to applicable standards of care.
The clinical responsibility for this code falls on the surgical team, including the surgeon, anesthesiologist, and potentially other specialists depending on the type of surgery and the patient's condition.Post-operative management would involve neurology and potentially other specialists depending on the extent of the infarction.

In simple words: A stroke that happens while someone is having surgery.This means that blood flow to the brain is cut off during the operation, leading to brain damage.
Intraoperative cerebrovascular infarction refers to a stroke that occurs during a surgical procedure.It involves the blockage of blood flow to a part of the brain, causing tissue damage and neurological dysfunction. This infarction is specifically identified as happening during an operation.
Example 1: A 70-year-old male patient undergoing a coronary artery bypass graft (CABG) experiences a sudden loss of consciousness and neurological deficits during the procedure.Post-operative imaging reveals an infarct in the left middle cerebral artery territory.Code I97.81 is applied, potentially with modifier I97.810 if it happened during the cardiac surgery., A 65-year-old female patient undergoing a carotid endarterectomy develops neurological symptoms during the operation, indicating a cerebrovascular event.Postoperative CT scan confirms an intraoperative stroke, and code I97.81 is assigned., During a complex abdominal surgery, a 55-year-old patient experiences a sudden drop in blood pressure and altered mental status. Neurologic assessment reveals a stroke affecting the right hemisphere.A post-operative CT angiogram reveals a vascular occlusion.Code I97.81 is utilized, with additional codes as clinically indicated to specify the location and type of stroke.
Detailed operative notes documenting the timing and onset of neurological symptoms during the surgical procedure, intraoperative monitoring data (EEG, blood pressure, etc.), and post-operative imaging studies (CT scan, MRI) confirming the infarction are necessary for accurate coding.A complete neurological assessment both pre and post-operatively is also crucial.The medical record should document the appropriate management.
** The severity of the intraoperative cerebrovascular infarction should be documented and considered for appropriate clinical management and further coding as needed.Additional codes may be necessary to reflect co-morbidities or complications.
