Terrorism w chemical weapons, terrorist injured, sequela

This code signifies long-term health consequences or residual effects stemming from an individual's exposure to chemical weapons during a terrorist act. It indicates that the patient was directly injured in such an event and is now presenting with conditions that are a direct result of that initial injury. These sequelae can manifest months or years after the initial exposure.

Apply this code when documenting a patient's current medical condition that is a direct, lasting consequence of a past injury sustained from a terrorist attack involving chemical weapons. This would be used for follow-up visits or admissions where the primary focus is managing these chronic or delayed effects. It is appropriate when the acute phase of the chemical injury has passed.

• Always sequence this code after the specific code(s) identifying the nature of the sequela (e.g., respiratory failure, neurological damage).
• Ensure documentation clearly links the current condition to the past chemical weapon exposure during a terrorist event.
• This "S" (sequela) character indicates a late effect, meaning the acute injury has healed, but residual conditions persist.
