Contus/lac/hem brainstem w LOC >24 hr w ret consc lev, subs

This code signifies a brainstem injury involving bruising, tearing, and bleeding, resulting in a coma or unconsciousness lasting more than 24 hours. Crucially, the patient has since regained their baseline level of consciousness. This code is used for follow-up care after the initial injury.

Apply this code for patients presenting for ongoing management, rehabilitation, or follow-up appointments related to a previously diagnosed brainstem injury with prolonged loss of consciousness. Documentation should clearly state the nature of the brainstem injury, the duration of unconsciousness exceeding 24 hours, and confirmation of the patient's return to their pre-injury conscious state.

• Ensure the "D" seventh character (subsequent encounter) is appropriate for the patient's current phase of care.
• Verify that the medical record explicitly documents the duration of unconsciousness as greater than 24 hours.
• Do not use this code if the patient has not returned to their pre-existing conscious level; a different seventh character or code may be more appropriate.
