Postproc hematoma of a nervous sys org fol other procedure

This code signifies the development of a localized collection of blood (hematoma) within or adjacent to a nervous system organ or structure, occurring as a complication after a surgical or interventional procedure other than a nervous system procedure itself. This postprocedural bleeding is an adverse event related to the intervention.

Apply this code when documentation clearly indicates a hematoma affecting the brain, spinal cord, or peripheral nerves, which developed as a direct consequence of a non-nervous system procedure. Examples include a hematoma compressing a nerve after a joint replacement, or an intracranial hematoma following a vascular access procedure. Documentation should specify the nervous system structure affected and the preceding procedure.

• Always sequence this code after the code identifying the specific nervous system condition or injury caused by the hematoma (e.g., nerve compression, cerebral edema).
• Ensure the documentation specifies that the hematoma is postprocedural and affects a nervous system component, distinguishing it from hematomas in other body systems.
• Do not use this code if the hematoma resulted from a procedure on the nervous system itself; refer to codes within the T81 series for complications of procedures on the nervous system.
