Toxic effect of venom of brown recluse spider, acc, subs

This code signifies a harmful reaction resulting from an unintentional bite by a brown recluse spider, specifically during the recovery phase after initial treatment. The patient is experiencing ongoing effects or complications from the venom, rather than the initial acute presentation.

Apply this code when documenting follow-up care for a patient who sustained an accidental brown recluse spider bite and is now presenting for subsequent treatment of the toxic effects. This includes scenarios such as wound debridement, management of necrosis, or treatment of secondary infections related to the bite, after the initial encounter.

• Ensure the documentation clearly states "accidental" or "unintentional" exposure.
• Confirm the encounter is for follow-up care, not the initial presentation of the bite.
• Always code the specific type of spider if known and documented.
