Toxic effect of venom of wasps, assault, initial encounter

This code signifies a patient presenting with adverse systemic effects resulting from the venom of a wasp, where the sting was intentionally inflicted by another person. The "initial encounter" designation indicates that this is the first time the patient is receiving active treatment for this specific injury.

Apply this code when documenting an emergency department visit or initial physician consultation for a patient who has been deliberately stung by a wasp, leading to symptoms such as anaphylaxis, localized severe reactions, or other systemic toxicities. This code is appropriate for the acute phase of treatment for the assault-related venom exposure.

• Always sequence this code as a primary diagnosis when the toxic effect is the reason for the encounter.
• Ensure documentation clearly supports the "assault" nature of the sting, not accidental or self-inflicted.
• Pair with an external cause code (e.g., X23.0XXA for contact with wasp, assault) to provide further detail on the circumstances.
