Toxic effect of lacrimogenic gas, self-harm, subs

This code signifies a harmful physiological reaction resulting from exposure to tear gas or similar riot control agents, where the exposure was self-inflicted with the intent to cause harm. The "subsequent encounter" aspect indicates that this code is used for follow-up care after the initial treatment for the toxic effect.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of complications arising from a self-inflicted toxic exposure to lacrimogenic gas. This includes follow-up appointments for respiratory issues, eye irritation, skin lesions, or psychological sequelae directly related to the initial self-harm event.

• Always sequence this code after the primary diagnosis for the specific toxic effect or injury.
• Ensure documentation clearly supports intentional self-harm and the "subsequent encounter" status.
• Do not use for accidental exposures or assaults; different codes apply for those scenarios.
