Toxic effect of contact w sea anemone, self-harm, subs

This code signifies a harmful reaction resulting from deliberate contact with a sea anemone, occurring during a follow-up visit after initial treatment. The patient intentionally exposed themselves to the sea anemone's toxins, leading to symptoms such as skin irritation, pain, or systemic effects. This code is used when the patient is receiving ongoing care for these self-inflicted injuries.

Apply this code for subsequent encounters where a patient is being treated for the lingering or evolving effects of a self-harm incident involving sea anemone contact. This includes follow-up appointments for wound care, management of persistent pain, or monitoring of systemic reactions. It is appropriate when the initial acute treatment has concluded, and the patient is in a recovery or ongoing management phase.

• Ensure documentation clearly indicates "intentional self-harm" and that the encounter is not the initial treatment.
• Always sequence this code after any codes for the specific manifestations of the toxic effect (e.g., dermatitis, anaphylaxis).
• Verify the encounter type is "subsequent" as indicated by the 7th character.
