Prim blst inj brain, NEC LOC >24 hr with ret consc lev, sqla

This code signifies a brain injury resulting from a primary blast exposure, not categorized elsewhere, where the patient experienced a loss of consciousness exceeding 24 hours. Crucially, the patient has since recovered to their baseline conscious level, and this code is used to indicate a late effect or complication of that injury.

Use this code for documentation indicating a patient is presenting for follow-up care or management of long-term sequelae directly attributable to a primary blast-induced brain injury. The medical record must clearly state a history of loss of consciousness greater than 24 hours due to the blast and a return to the patient's pre-injury conscious state.

• Always sequence this sequela code after the code for the specific late effect or complication being treated.
• Ensure documentation explicitly states "primary blast injury" and the duration of unconsciousness to avoid miscoding.
• Do not use this code for acute blast injuries; it is specifically for the sequela phase.
