Intraop hemor/hemtom of a nervous sys org comp nrv sys proc

This code signifies bleeding or a collection of blood within a nervous system organ or structure that occurs during a surgical procedure on the nervous system. This complication is directly related to the operative intervention rather than a pre-existing condition.

Apply this code when documentation clearly indicates intraoperative hemorrhage or hematoma formation during a neurosurgical procedure, such as craniotomy, laminectomy, or spinal fusion. The physician's operative report should describe the bleeding event, its location, and its relationship to the surgical manipulation.

• Always sequence this code as a secondary diagnosis, following the code for the underlying nervous system procedure complication (e.g., T81.0-).
• Distinguish from postoperative hemorrhage/hematoma (T81.0-) which occurs after the patient has left the operating room.
• Ensure the documentation specifies "intraoperative" to support the use of this code, as opposed to pre-existing or delayed bleeding.
