Toxic effect of unsp seafood, intentional self-harm, sequela

This code signifies a long-term or residual health problem resulting from a deliberate act of self-poisoning using an unidentified type of seafood. The patient intentionally ingested the seafood with the intent to harm themselves, and the current medical encounter addresses a lasting consequence of that toxic exposure.

Apply this code when documenting a patient presenting with a chronic or permanent condition directly attributable to a past intentional self-harm attempt involving unspecified seafood. This would be used for follow-up care or management of sequelae, not for the initial acute poisoning event.

• Ensure documentation clearly states the seafood ingestion was intentional self-harm and that the current condition is a sequela.
• Do not use this code for acute poisoning or accidental exposure; those require different codes.
• Always code the specific sequela (e.g., kidney damage, neurological deficit) first, followed by this code as an external cause of morbidity.
