I97.811

HCC Category Mapping

What This Code Means

A stroke caused by a blood clot or blocked blood vessel in the brain that occurs during a surgical procedure other than heart or blood vessel surgery. This is a serious complication that happens while the patient is under anesthesia or during the operation itself.

Coding Tips

• •This code requires documentation that the infarction occurred intraoperatively (during the surgery) and is not a pre-existing condition; always link this to the principal procedure code to establish the causal relationship
• •Do not use this code for cerebrovascular infarctions that occur during cardiac surgery (use I97.81-) or vascular surgery (use I97.82-); verify the type of surgery performed to select the correct intraoperative complication code

Clinical Significance

Intraoperative cerebrovascular infarction during other (non-cardiac) surgery is a serious surgical complication representing a stroke that occurred as a direct result of a surgical procedure. This diagnosis indicates significant perioperative morbidity with potential for permanent neurological deficits, extended intensive care stays, and long-term rehabilitation needs. It reflects both the complexity of the surgical case and the patient's elevated cerebrovascular risk profile.

Documentation Requirements

• ✓Clear documentation that the cerebrovascular infarction occurred during the surgical procedure
• ✓Type of surgery identified as other (non-cardiac) surgery
• ✓Temporal relationship between the surgery and the infarction explicitly documented
• ✓Neurological findings and imaging results confirming the infarction
• ✓Causal relationship between the procedure and the infarction stated or implied by the provider
• ✓Neurological deficits documented (type, severity, laterality)
• ✓Treatment interventions for the cerebrovascular event documented
