Legal intervnt involving unsp gas, bystander injured, init

This code signifies an injury sustained by an individual who was not directly involved in a legal intervention but was present when an unspecified gas was used. The injury is a direct result of exposure to this gas during the intervention.

Apply this code when documenting an injury to a bystander who was exposed to an unknown or unspecified gas during a law enforcement or other legal intervention. This is for the initial treatment of the injury.

• Ensure the documentation clearly states the patient was a bystander and not the target of the intervention.
• Verify that the type of gas involved is not specified in the medical record.
• Confirm this is the first encounter for the injury; subsequent encounters will require a different seventh character.
