Toxic effect of contact w sea anemone, accidental, subs

This code signifies a toxic reaction resulting from unintentional contact with a sea anemone, where the patient is receiving follow-up care for the initial injury. The patient may present with persistent skin irritation, pain, or other systemic symptoms after the initial treatment.

Apply this code when documenting a patient's visit for ongoing management or complications related to an accidental sea anemone sting. This includes follow-up appointments for wound care, persistent allergic reactions, or monitoring for delayed systemic effects.

• Ensure the encounter is for follow-up care, not the initial treatment.
• Verify that the contact was accidental and not intentional (e.g., occupational exposure).
• Always code with an external cause code (V00-Y99) to describe the circumstances of the injury.
