Toxic effect of venom of ants, intentional self-harm, subs

This code signifies a harmful reaction resulting from the deliberate self-administration of ant venom. The patient intentionally exposed themselves to the venom, and this particular encounter represents follow-up care or a subsequent visit related to the initial self-harm incident. The toxic effect could manifest as localized reactions, systemic symptoms, or anaphylaxis.

Apply this code for a patient presenting for ongoing management, monitoring, or treatment of complications stemming from a prior intentional self-inflicted ant venom exposure. This includes follow-up appointments after initial emergency care, or visits for persistent symptoms or delayed reactions. It is crucial that the encounter is not the initial treatment for the self-harm event.

• Ensure documentation clearly states "intentional self-harm" and specifies "subsequent encounter."
• Always code the specific toxic effect (e.g., anaphylactic shock, dermatitis) as a primary diagnosis if applicable.
• Do not use for accidental exposures or initial treatment of the self-harm event.
