Traumatic cerebral edema w LOC of 31-59 min, sequela

This code signifies a chronic or late effect of traumatic cerebral edema that was initially associated with a moderate period of unconsciousness, specifically lasting between 31 and 59 minutes. It indicates that the patient is now experiencing residual symptoms or complications directly attributable to this past brain injury.

Apply this code when documenting a patient presenting with ongoing neurological deficits, cognitive impairments, or other long-term sequelae resulting from a traumatic brain injury that involved cerebral edema and a loss of consciousness within the specified timeframe. Documentation should clearly link the current condition to the prior TBI and specify the duration of unconsciousness.

• Always sequence this sequela code after the code for the specific residual condition (e.g., cognitive deficit, hemiplegia).
• Ensure the medical record explicitly states "sequela" or "late effect" and confirms the original injury involved cerebral edema and LOC of 31-59 minutes.
• Differentiate from acute injury codes (S06.1X2A/D) which are used for initial encounters or subsequent encounters for active treatment of the injury itself.
