Ciguatera fish poisoning, intentional self-harm, sequela

This code signifies the long-term or residual effects resulting from a patient's deliberate self-infliction of ciguatera fish poisoning. These sequelae can manifest as chronic neurological, gastrointestinal, or cardiovascular symptoms that persist after the initial acute poisoning event.

Apply this code when documenting conditions directly attributable to a past, intentional self-harm attempt involving ciguatera fish poisoning. This is appropriate for follow-up visits or when the patient presents with ongoing health issues clearly linked to the prior self-poisoning incident.

• Always sequence this code after the code for the specific sequela being treated (e.g., chronic neuropathy).
• Ensure documentation clearly links the current condition to the past intentional ciguatera poisoning.
• The "S" in the 7th character indicates sequela, meaning the patient is experiencing residual effects from a past event.
