Toxic effect of venom of wasps, undetermined, sequela

This code indicates a long-term or residual effect from a wasp venom exposure where the intent (accidental, intentional self-harm, assault) is unknown. It signifies that the acute phase of the envenomation has passed, but the patient continues to experience symptoms or complications directly attributable to the venom.

Use this code when documenting a follow-up visit for a patient experiencing persistent neurological, dermatological, or systemic issues (e.g., chronic pain, localized tissue damage, ongoing allergic reactions) weeks or months after a wasp sting, and the circumstances of the sting are not specified. This code is appropriate when the initial acute treatment for the sting has concluded, but the patient requires ongoing management for sequelae.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic urticaria, peripheral neuropathy).
• The "S" seventh character indicates a sequela, meaning it's for complications or conditions arising as a direct result of an earlier injury or disease.
• Do not use for acute envenomation; use acute poisoning codes for initial treatment.
