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

This code describes a cerebral contusion and laceration, where the specific location within the cerebrum is not documented. The patient experienced a loss of consciousness exceeding 24 hours but has since returned to their baseline conscious state. This code is for a subsequent encounter, meaning the patient is receiving follow-up care for this injury.

Use this code for follow-up visits or ongoing management of a patient who previously sustained an unspecified cerebral contusion and laceration with prolonged loss of consciousness (over 24 hours) and has since regained their pre-injury conscious level. Documentation must clearly indicate the "subsequent encounter" status and the resolution of the prolonged loss of consciousness.

• Ensure documentation specifies "subsequent encounter" and not an initial treatment for the injury.
• Verify the duration of loss of consciousness was explicitly greater than 24 hours and that the patient has returned to their baseline.
• Do not use if the specific cerebral lobe (e.g., frontal, temporal) is documented; more specific codes exist for those scenarios.
