Postp hematoma of a nervous sys org fol a nervous sys proc

This code signifies the development of a localized collection of blood (hematoma) within or around a component of the central or peripheral nervous system, occurring as a direct complication after a surgical or interventional procedure performed on that nervous system structure. It indicates a post-operative bleeding event affecting the brain, spinal cord, or associated nerves.

Apply this code when documentation clearly states a hematoma formed in a nervous system organ or structure subsequent to a nervous system procedure. This includes scenarios such as an intracranial hematoma after craniotomy, a spinal epidural hematoma following spinal surgery, or a peripheral nerve sheath hematoma after nerve decompression. The physician's notes should explicitly link the hematoma to the recent nervous system intervention.

• Ensure the documentation specifies the hematoma's location within a nervous system structure and its direct relationship to a preceding nervous system procedure.
• Do not confuse with spontaneous hematomas or those unrelated to a procedure; these would be coded differently based on etiology.
• Sequence this code after the primary diagnosis for which the procedure was performed, and potentially after a code for the specific nervous system procedure if applicable.
