Scombroid fish poisoning, assault, sequela

This code describes the long-term or residual effects resulting from scombroid fish poisoning that was intentionally inflicted upon the patient. Scombroid poisoning is a type of foodborne illness caused by consuming fish with high levels of histamine due to improper storage. The "assault" designation indicates the poisoning was a deliberate act by another party.

Use this code when documenting a patient presenting with persistent symptoms or complications directly attributable to a past scombroid fish poisoning event, and the medical record clearly indicates the poisoning was the result of an assault. This code is appropriate for follow-up visits addressing chronic issues like persistent neurological symptoms, dermatological conditions, or gastrointestinal sequelae.

• Always ensure the medical record explicitly states both the scombroid fish poisoning and the assault as the cause of the sequela.
• Do not use this code for the initial acute poisoning event; it is specifically for the sequelae.
• Remember the "S" seventh character indicates sequela, meaning the patient is experiencing the residual effects of a previous injury or condition.
