Toxic effect of venom of wasps, assault, subs encntr

This code signifies a patient presenting with systemic or localized toxic effects resulting from a wasp venom exposure, specifically when the encounter is for follow-up care of an injury intentionally inflicted by another person. It indicates the sequelae of the venom rather than the sting itself.

Apply this code for subsequent encounters when managing complications or ongoing symptoms from a wasp sting that was an act of assault. This includes follow-up visits for persistent localized reactions, systemic allergic responses, or other venom-related toxicities.

• Ensure the encounter is for follow-up care, not the initial presentation.
• Confirm documentation explicitly states the wasp sting was an assault.
• Code the specific toxic effect (e.g., anaphylaxis, cellulitis) as a primary diagnosis if applicable, with this code as an external cause.
