Toxic effect of contact w sea anemone, undetermined, subs

This code signifies a toxic reaction resulting from direct skin contact with a sea anemone, where the intent (accidental, intentional self-harm, assault) of the exposure is not documented. It is used for encounters following the initial treatment of the injury, indicating ongoing care, follow-up, or management of residual effects.

Apply this code when a patient presents for follow-up care of symptoms or complications stemming from a sea anemone sting, and the circumstances surrounding the contact were not specified or are unknown. This includes subsequent visits for wound care, management of persistent rash, or monitoring for delayed systemic reactions.

• Ensure documentation clearly states this is a subsequent encounter for the sea anemone exposure.
• Confirm the medical record does not specify the intent of the contact (e.g., accidental, intentional).
• Pair with external cause codes (e.g., W59.XXXD) if available and applicable, to provide more context about the event.
