Legal intervnt w oth gas, law enforc offl injured, subs

This code describes an injury sustained by a law enforcement official during a legal intervention that involved the use of a gas other than tear gas. It specifically indicates that this is a subsequent encounter, meaning the patient is receiving follow-up care for an injury that occurred previously.

This code is appropriate for documenting ongoing treatment, rehabilitation, or follow-up visits for a law enforcement officer who was injured by a non-tear gas agent during an arrest or other official duty. Examples include injuries from pepper spray, stun gas, or other chemical agents used in a legal intervention.

• Ensure the documentation clearly specifies a "subsequent encounter" for this injury.
• Verify the gas involved was not tear gas, as a different code exists for that scenario.
• Always sequence this external cause code after the primary diagnosis code for the injury itself.
