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

This code signifies a past cerebral contusion or laceration that resulted in a prolonged loss of consciousness exceeding 24 hours, from which the patient eventually recovered to their baseline conscious level. It indicates the long-term effects or complications stemming from this specific type of traumatic brain injury.

Use this code when documenting the sequelae of a cerebral contusion or laceration where the initial injury involved a loss of consciousness lasting more than 24 hours, and the patient has since returned to their pre-injury conscious state. This code is appropriate for encounters addressing the residual effects or ongoing management related to that past severe TBI. Documentation must clearly state the nature of the original injury, the duration of unconsciousness, and the current conscious level.

• Always sequence this sequela code after the primary reason for the current encounter.
• Ensure documentation explicitly states "loss of consciousness greater than 24 hours" and "return to pre-existing conscious level."
• Do not use for acute injuries; this code is exclusively for the sequela phase.
