Contus/lac/hem brainstem w LOC of 6 hours to 24 hours, subs

This code signifies a traumatic injury to the brainstem, characterized by bruising, tearing, and bleeding, that resulted in a prolonged loss of consciousness lasting between 6 and 24 hours. This specific code is used when the patient is receiving follow-up care for this previously diagnosed injury.

This code is appropriate for subsequent encounters where a patient is being treated for the sequelae or ongoing management of a brainstem contusion, laceration, and hemorrhage that initially caused a loss of consciousness for 6 to 24 hours. Documentation should clearly indicate the nature of the brainstem injury, the duration of the initial loss of consciousness, and that the current visit is not the initial treatment for the acute injury.

• Ensure documentation specifies "subsequent encounter" for this specific injury.
• Verify the exact duration of loss of consciousness; codes vary based on timeframes.
• Do not use for initial acute care; a different code reflecting the initial encounter would be appropriate.
