Scombroid fish poisoning, assault, subsequent encounter

This code signifies a patient presenting for follow-up care or treatment of scombroid fish poisoning that was intentionally inflicted by another person. Scombroid poisoning results from consuming fish (e.g., tuna, mackerel, mahi-mahi) containing high levels of histamine due to improper handling, leading to symptoms like flushing, headache, palpitations, and gastrointestinal distress.

Apply this code when documenting subsequent encounters for a patient receiving ongoing management, monitoring, or treatment for scombroid fish poisoning that was the result of an assault. This includes visits for medication adjustments, symptom resolution checks, or addressing any lingering effects after the initial acute phase.

• Ensure documentation clearly states the poisoning was due to an assault and that this is not the initial encounter for the injury.
• Always sequence this code after the primary code for the specific type of scombroid fish poisoning.
• Consider additional external cause codes (e.g., Y05.-) to further specify the perpetrator if known and documented.
