Toxic effect of venom of wasps, accidental, subs

This code signifies a patient presenting for follow-up care related to an accidental poisoning from wasp venom. This could involve monitoring for delayed reactions, managing persistent symptoms, or addressing complications that arose after the initial treatment for the sting.

Apply this code when a patient returns for subsequent evaluation or treatment of symptoms, complications, or sequelae stemming from an unintentional wasp sting. This includes visits for wound care, allergy management, or monitoring for systemic effects after the initial encounter.

• Ensure documentation clearly indicates an accidental exposure and that this is not the initial visit for the sting.
• Pair with external cause codes (e.g., W57.XXXD) to fully describe the circumstances of the injury.
• Distinguish from initial encounters (A) and sequela encounters (S) based on the patient's current stage of care.
