Toxic effect of contact w venomous toad, undetermined, subs

This code signifies a toxic reaction resulting from direct skin contact with a venomous toad, where the specific type of toad or venom is not identified. The encounter is not the initial presentation but rather a follow-up visit for ongoing management or complications related to the original exposure. Symptoms can range from localized irritation to systemic effects depending on the venom and individual sensitivity.

This code is appropriate for documenting follow-up care for a patient who previously presented with a toxic effect from venomous toad contact. This includes subsequent visits for wound care, monitoring of systemic symptoms, or management of delayed complications. It should be used when the initial encounter for the poisoning has already been coded.

• Assign this code only for follow-up encounters after the initial poisoning event.
• Ensure documentation clearly states "undetermined" regarding the specific venomous toad if no further identification is made.
• Always sequence this code after any codes for the specific signs and symptoms or complications being treated.
