Toxic effect of contact w oth jellyfish, self-harm, init

This diagnosis code signifies a harmful reaction resulting from deliberate contact with a jellyfish species other than those specifically classified elsewhere. The patient intentionally exposed themselves to the jellyfish, leading to a toxic effect. This code is used for the initial presentation of such an injury.

Apply this code when documenting a patient presenting with symptoms of envenomation (e.g., rash, pain, swelling, systemic effects) after intentionally touching a jellyfish. This would include scenarios where the patient deliberately handled a jellyfish, or otherwise sought out contact with it, resulting in an adverse reaction.

• Always assign an external cause code (e.g., X26.XXXA) to provide additional detail about the circumstances of the injury.
• Ensure documentation clearly indicates the "intentional self-harm" nature of the contact, differentiating it from accidental exposure.
• Confirm the encounter is the initial treatment for this specific injury; subsequent encounters would use a different seventh character.
