Injury due to legal intervention by gas

This code signifies an injury sustained by an individual as a direct result of law enforcement or legal authority actions involving the use of gas. This includes injuries from tear gas, pepper spray, or other chemical agents deployed during arrests, crowd control, or other legal interventions. The injury itself, not the intent of the legal intervention, is the focus.

Apply this code when documentation clearly states an injury occurred due to gas deployed by legal intervention. This typically involves scenarios such as chemical irritant exposure during an arrest, riot control, or other law enforcement operations. Supporting documentation would include incident reports, police reports, and physician notes detailing the cause of injury.

• Always code the specific injury first, then use this E-code as a secondary diagnosis to describe the external cause.
• Distinguish from accidental exposure to gas (e.g., industrial accidents) or intentional self-harm using gas.
• Ensure the documentation explicitly links the gas exposure to legal intervention, not just general exposure to gas.
