Terrorism involving chemical weapons, civilian injured, init

This code signifies an injury sustained by a civilian as a direct result of a terrorist act involving chemical weapons. It indicates the patient is in the initial phase of receiving active treatment for these injuries. The chemical exposure is the primary mechanism of harm in this specific scenario.

Apply this code for patients presenting with acute injuries or illnesses directly attributable to a chemical weapon attack in a civilian setting. This includes initial emergency department visits, hospital admissions, or outpatient encounters for immediate management of chemical exposure symptoms. It should be used when the patient is first seen for this specific event.

• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Ensure documentation clearly specifies civilian status and the use of chemical weapons in a terrorist act.
• Do not use for subsequent encounters or sequelae; a different encounter character would be required.
