Toxic effect of venom of tarantula, undetermined, subs

This code signifies a harmful systemic reaction to tarantula venom, where the specific circumstances of the exposure are not yet determined. It indicates that the patient is receiving ongoing care for the effects of the envenomation after the initial treatment.

Apply this code when a patient presents for follow-up care, such as wound checks, medication adjustments, or monitoring of systemic symptoms, following a tarantula bite. It is appropriate when the initial encounter for the bite has already been coded, and the intent of the encounter is for continued management of the toxic effects.

• Use this code for subsequent encounters only; an initial encounter code would be used for the first visit.
• Ensure documentation clearly supports the "undetermined" nature of the venom's toxic effect if specific details are unknown.
• Always sequence this code after any codes for the specific symptoms or complications arising from the envenomation.
