Toxic effect of contact w oth venomous plant, undet, subs

This code signifies a harmful reaction resulting from skin contact with an unspecified venomous plant, where the intent (accidental, intentional self-harm, assault) is not documented. The patient is presenting for follow-up care after the initial treatment of the toxic effect.

Apply this code when a patient returns for subsequent treatment of symptoms like dermatitis, rash, or other localized reactions caused by an unknown venomous plant. This is appropriate for ongoing management of the toxic effect, such as wound care, medication adjustments, or monitoring for complications, when the initial encounter has already been coded.

• Ensure the documentation clearly indicates a follow-up encounter for the toxic effect, not the initial presentation.
• Only use this code when the specific type of venomous plant is not identified in the medical record.
• Always sequence this code after any codes for the specific symptoms or conditions resulting from the toxic effect.
