Toxic effect of venom of hornets, accidental, sequela

This code signifies the long-term or residual health problems resulting from an accidental hornet venom exposure. It indicates that the acute toxic effects have resolved, but the patient continues to experience lasting symptoms or complications directly attributable to the envenomation.

Use this code when documenting conditions such as chronic localized pain, persistent swelling, scarring, or neurological deficits that are a direct consequence of an unintentional hornet sting and are being addressed after the initial acute phase of treatment. This applies to follow-up encounters for these lasting effects.

• Always sequence this code after the code for the specific sequela being treated (e.g., chronic pain, scar).
• Ensure documentation clearly links the current condition to a past accidental hornet sting.
• Do not use for acute toxic effects; those require codes from the initial encounter.
