Ciguatera fish poisoning, assault, subsequent encounter

This code signifies a diagnosis of ciguatera fish poisoning that occurred as a result of an assault. Ciguatera poisoning is caused by consuming fish contaminated with ciguatoxins, leading to a range of gastrointestinal, neurological, and cardiovascular symptoms. The "subsequent encounter" indicates that the patient is receiving follow-up care for this specific poisoning event.

Use this code when a patient presents for ongoing management, monitoring, or treatment of ciguatera fish poisoning that was intentionally inflicted by another person. This would include scenarios such as follow-up appointments for persistent neurological symptoms or ongoing gastrointestinal issues related to the initial poisoning.

• Always assign an external cause code (Y07.-) to fully describe the assault.
• Ensure documentation clearly specifies the "subsequent encounter" for the poisoning, not the initial presentation.
• Verify that the poisoning is explicitly documented as an assault to justify the "assault" specificity.
