Toxic effect of venom of hornets, accidental, subs

This code describes the lingering or ongoing health issues resulting from an accidental hornet sting. It indicates that the patient is receiving follow-up care for complications or persistent symptoms after the initial treatment for the venom's toxic effects.

Apply this code when a patient presents for subsequent care related to a hornet sting, such as managing a persistent allergic reaction, treating a secondary infection at the sting site, or monitoring for delayed systemic effects. This code is appropriate for visits occurring after the initial encounter for the sting.

• Ensure documentation clearly states the encounter is for follow-up care related to the hornet sting.
• Confirm the sting was accidental, not intentional.
• Pair with additional codes for specific symptoms or complications being treated during the subsequent encounter.
