Intcran inj w LOC >24 hr w ret consc lev, subs

This code signifies a follow-up encounter for a patient who sustained an intracranial injury, other than those specifically classified, that resulted in a loss of consciousness exceeding 24 hours. Crucially, the patient has since recovered to their baseline conscious level. This indicates a significant, but resolving, neurological insult.

This code is appropriate for subsequent encounters when a patient is being monitored or treated for the residual effects of a severe intracranial injury, where the initial loss of consciousness was prolonged but has since resolved. Documentation should clearly state the type of intracranial injury (if not otherwise specified), the duration of unconsciousness, and confirmation of return to pre-injury conscious state.

• Requires a seventh character of "D" for subsequent encounter; do not use "A" for initial or "S" for sequela.
• Distinguish from codes where loss of consciousness is less than 24 hours or where the patient has not returned to their pre-existing conscious level.
• Always code the specific type of intracranial injury first, if known and more specific.
