Other shellfish poisoning, assault, initial encounter

This code signifies a patient presenting with symptoms of poisoning specifically caused by the ingestion of shellfish, excluding ciguatera, paralytic, neurotoxic, or amnesic shellfish poisoning. The poisoning is explicitly identified as resulting from an assault, meaning the shellfish was intentionally administered with harmful intent. This is the initial encounter for this specific poisoning event.

Use this code when documenting a patient's first presentation for treatment of shellfish poisoning where the medical record clearly indicates the poisoning was due to an intentional act by another party. This would apply to situations such as a patient being deliberately given contaminated shellfish by someone else. It is crucial that the documentation supports both the shellfish as the source of poisoning and the assaultive nature of the exposure.

• Ensure documentation clearly distinguishes "other shellfish" from ciguatera, paralytic, neurotoxic, or amnesic types.
• Verify the medical record explicitly states the poisoning was due to an assault, not accidental or self-inflicted.
• Confirm this is the initial encounter for this specific poisoning event; subsequent encounters will require a different seventh character.
