Diffuse TBI w LOC >24 hr w return to conscious levels, subs

This code signifies a widespread traumatic brain injury where the patient experienced a coma lasting over 24 hours but has since recovered to their baseline cognitive state. It indicates that the patient is in the healing phase of this severe brain trauma.

Apply this code for follow-up visits or ongoing treatment of a patient previously diagnosed with a diffuse TBI that resulted in prolonged loss of consciousness (over 24 hours) and has since resolved to their pre-injury conscious level. Documentation should clearly state the history of the TBI, the duration of unconsciousness, and the current neurological status indicating return to baseline.

• Ensure documentation specifies "diffuse" TBI and not a focal injury.
• Verify the duration of loss of consciousness was explicitly "greater than 24 hours."
• Confirm the patient's current conscious level has returned to their pre-injury baseline, as this differentiates it from codes indicating ongoing altered consciousness.
