Traum cerebral edema w LOC >24 hr w/o ret consc w surv, subs

This code signifies a subsequent encounter for a patient experiencing traumatic cerebral edema that resulted in a loss of consciousness lasting over 24 hours, with the patient not returning to their pre-injury baseline conscious level. It indicates ongoing management or follow-up care for the persistent neurological sequelae of severe traumatic brain injury.

Use this code for follow-up visits, rehabilitation sessions, or ongoing medical management when a patient is still recovering from traumatic cerebral edema with prolonged loss of consciousness and has not regained their pre-injury cognitive status. Documentation should clearly state the traumatic etiology, the duration of unconsciousness exceeding 24 hours, the patient's current altered conscious level, and that this is not the initial treatment encounter.

• Ensure documentation specifies "subsequent encounter" and not an initial or sequela encounter.
• Verify the duration of unconsciousness explicitly stated as greater than 24 hours.
• Confirm the patient has not returned to their pre-existing conscious level, differentiating it from full recovery.
