Toxic effect of cntct with Portuguese Man-o-war, undet, subs

This code signifies a harmful systemic reaction resulting from skin contact with a Portuguese Man-o-war, where the intent of the exposure (accidental vs. intentional) cannot be determined. The "subsequent encounter" indicates that this code is used for follow-up care after the initial treatment of the toxic effect.

Apply this code for patients presenting for ongoing management or evaluation of symptoms related to a Portuguese Man-o-war sting, when the circumstances surrounding the contact are not clearly documented as accidental or intentional. This includes follow-up appointments for wound care, pain management, or assessment of lingering systemic effects.

• Always assign an external cause code (V00-Y99) in conjunction with this code to fully describe the circumstances of the injury.
• Ensure documentation clearly supports "undetermined" intent; otherwise, consider codes for accidental or intentional exposure.
• This "D" seventh character is used for encounters after the active treatment of the acute injury.
