Legal intervnt involving unsp gas, bystander injured, subs

This code signifies an injury sustained by a bystander due to legal intervention involving the use of an unspecified gas. The injury is a direct result of the intervention, not the primary target, and the encounter being documented is a subsequent visit for this specific injury.

Apply this code when a patient presents for follow-up care for an injury (e.g., respiratory irritation, skin rash, eye injury) sustained as an uninvolved party during a law enforcement action where gas was deployed. This would include situations like tear gas or pepper spray used to disperse crowds, affecting individuals not directly targeted.

• Ensure the patient was a bystander and not the intended recipient of the legal intervention.
• Verify that the injury was caused by an unspecified gas, not another form of legal intervention.
• Confirm this is a subsequent encounter for the injury, not the initial presentation.
