Toxic effect of venom of black widow spider, acc, subs

This code signifies a patient presenting for follow-up care or ongoing treatment related to the toxic effects resulting from an accidental black widow spider bite. The initial acute phase of the envenomation has passed, and the patient is now receiving care for complications, healing, or monitoring.

Apply this code when a patient returns for a wound check, medication adjustment, or management of persistent symptoms (e.g., muscle cramps, pain, or neurological effects) after the initial treatment for a black widow spider bite. It is appropriate for any encounter following the initial diagnosis and treatment of the envenomation.

• Ensure the encounter is for ongoing care, not the initial presentation.
• Verify the documentation specifies "accidental" or "unintentional" exposure.
• Consider additional codes for specific symptoms or complications if documented.
