Other fish poisoning, intentional self-harm, sequela

This code signifies the long-term or residual effects resulting from a deliberate act of self-poisoning using fish or fish products, excluding ciguatera or scombroid poisoning. It indicates that the patient intentionally ingested the fish with the intent to harm themselves, and they are now presenting with lasting health issues attributable to that event.

Apply this code when documenting follow-up care for a patient who previously attempted suicide or self-harm by ingesting fish, and is now experiencing chronic or persistent complications directly related to that poisoning. This would include conditions like ongoing neurological deficits, organ damage, or chronic gastrointestinal issues that are a direct consequence of the intentional fish poisoning.

• Requires a documented history of intentional self-harm via fish ingestion.
• Only use for sequelae (late effects), not for the initial acute poisoning episode.
• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease due to poisoning).
