Other shellfish poisoning, intentional self-harm, sequela

This code signifies the long-term or residual effects resulting from an intentional act of self-poisoning using shellfish. It indicates that the patient previously ingested shellfish with the intent to harm themselves, and they are now presenting with persistent health issues directly attributable to that event.

Apply this code when documenting a patient's current medical condition that is a direct consequence of a past, deliberate self-harm attempt involving shellfish ingestion. This would include chronic neurological deficits, organ damage, or other lasting complications identified during follow-up care for such an event.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past intentional shellfish poisoning.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
