Terrorism involving nuclear weapons, civilian injured, subs

This code signifies a civilian's injury resulting from a terrorist act involving nuclear weapons, specifically during a follow-up visit or subsequent phase of care. It indicates that the patient is receiving ongoing treatment or monitoring for conditions directly attributable to this catastrophic event.

Apply this code for any encounter after the initial treatment for a civilian injured by a nuclear weapons terrorist attack. This includes follow-up appointments for radiation sickness, burns, trauma, or long-term health effects stemming from the initial incident. It is appropriate for managing chronic conditions or complications that arise post-initial stabilization.

• Always pair this code with an external cause code for the specific injury or condition being treated.
• Ensure documentation clearly specifies "civilian" and "subsequent encounter" to justify its use.
• Distinguish carefully from initial encounter codes (A) or sequela codes (S) if the patient's status changes.
