Toxic effect of venom of wasps, undetermined, subs encntr

This code signifies a harmful systemic reaction to wasp venom, where the intent (accidental or intentional self-harm) is not documented. It is used when a patient is receiving follow-up care for the toxic effects, such as ongoing treatment for anaphylaxis, localized tissue damage, or other systemic symptoms.

Apply this code for patients presenting for continued management of symptoms or complications arising from a wasp sting, after the initial encounter. This includes situations where the patient is seen for medication adjustments, wound care, or monitoring of organ system involvement related to the venom's toxic effects.

• Ensure documentation clearly indicates "subsequent encounter" for the toxic effect.
• Do not use this code for the initial treatment of the wasp sting; a different encounter character is required.
• Always code the specific symptoms or complications resulting from the toxic effect in addition to this code.
