Terrorism involving chemical weapons, civilian injured, subs

This code signifies that a civilian has sustained injuries as a direct result of a terrorist act involving chemical weapons. It specifically applies to encounters occurring after the initial treatment of these injuries, indicating ongoing care or follow-up. The patient's condition is a consequence of exposure to a chemical agent used in a deliberate act of terror.

Use this code for follow-up visits, rehabilitation, or ongoing management of health issues stemming from chemical weapon exposure in a terrorist event. This includes scenarios where the patient is experiencing delayed effects, chronic conditions, or psychological trauma related to the initial incident. It is appropriate for any encounter after the initial emergency treatment.

• Ensure documentation clearly states the patient is a civilian and the encounter is subsequent to the initial injury.
• Always code the specific injury or condition resulting from the chemical weapon exposure first, followed by this external cause code.
• Verify that the incident is explicitly documented as a terrorist act involving chemical weapons, not accidental exposure or other forms of assault.
