Other intraoperative complications of nervous system

This code signifies an unexpected and undesirable event affecting the nervous system that occurs during a surgical or other invasive procedure. It encompasses complications such as nerve injury, spinal cord damage, or cerebral edema that arise directly from the intraoperative process, excluding those specified by other more precise codes.

Use this code when documentation clearly indicates an intraoperative complication involving the nervous system that is not otherwise classified. This typically applies when the operative report or anesthesia record describes an adverse neurological event during the procedure, such as an unexpected nerve laceration, compression, or ischemia.

• Ensure the documentation explicitly states the complication occurred intraoperatively and affected the nervous system.
• Always sequence this code after the code for the primary procedure performed.
• Distinguish from postoperative complications (T80-T88 series) or complications of anesthesia (T88.5-T88.6).
