Contus/lac left cerebrum w LOC >24 hr w ret consc lev, subs

This code signifies a brain injury involving both bruising and tearing of the left cerebrum, resulting in a loss of consciousness that lasted for more than 24 hours. Crucially, the patient has since regained their baseline level of consciousness. This code is used for subsequent encounters after the initial treatment of the injury.

Use this code for follow-up visits, rehabilitation sessions, or ongoing management of a patient who previously sustained a severe left cerebral contusion and laceration with prolonged loss of consciousness. Documentation should clearly indicate that the patient's consciousness has returned to their pre-injury state and that this is not the initial encounter for the injury.

• Ensure the documentation specifies "left cerebrum" and "loss of consciousness greater than 24 hours with return to pre-existing conscious level."
• This "D" seventh character indicates a subsequent encounter; do not use for the initial treatment of the injury.
• Always sequence this code after any acute traumatic brain injury codes if the patient is still being treated for other acute aspects of the injury.
