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

This code signifies a harmful reaction resulting from accidental contact with a Portuguese Man-o-war, specifically when the patient is receiving follow-up care for the initial injury. The toxic effects can range from severe pain and skin irritation to systemic symptoms like nausea, vomiting, and muscle cramps.

Apply this code for subsequent encounters where a patient is being treated for ongoing symptoms or complications arising from an unintentional Portuguese Man-o-war sting. This includes visits for wound care, management of persistent pain, or addressing delayed allergic reactions after the initial treatment.

• Ensure the documentation clearly indicates an "accidental" exposure, not intentional.
• Verify the encounter is for follow-up care, not the initial treatment, due to the "D" seventh character.
• Always code any specific symptoms or complications (e.g., dermatitis, anaphylaxis) in addition to this code.
