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

This code signifies a delayed or residual health problem resulting from a self-inflicted injury caused by contact with a sea anemone. The initial toxic reaction has resolved, but the patient continues to experience lasting effects such as chronic pain, scarring, or neurological deficits directly attributable to the original poisoning.

Apply this code when documenting a follow-up encounter for a patient presenting with persistent symptoms or complications from a previous intentional sea anemone sting. This would include scenarios where the patient is being treated for long-term skin changes, nerve damage, or other chronic conditions that developed after the acute toxic exposure.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic dermatitis, neuropathy).
• Ensure documentation clearly links the current condition to the past intentional sea anemone contact.
• Verify the "S" seventh character is appropriate for a sequela, indicating a late effect.
