Toxic effect of venom of ants, accidental, sequela

This code signifies a lasting health problem or complication resulting from an accidental ant venom exposure. It indicates that the acute toxic effects have resolved, but the patient continues to experience residual symptoms or conditions directly attributable to the original envenomation.

Apply this code when documenting chronic dermatitis, persistent neurological deficits, or long-term allergic reactions (e.g., chronic urticaria, asthma) that are a direct consequence of an accidental ant sting. This code is appropriate for follow-up encounters addressing these enduring sequelae, not the initial acute toxic event.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past accidental ant venom exposure.
• Do not use for acute toxic effects; those require an initial encounter or subsequent encounter code.
