Other fish poisoning, assault, subsequent encounter

This code signifies a patient's adverse reaction to consuming contaminated fish, excluding ciguatera, scombroid, and shellfish poisoning, where the poisoning was intentionally inflicted by another person. The "subsequent encounter" indicates that the patient is receiving follow-up care for this specific poisoning event after the initial treatment.

Apply this code when documenting ongoing treatment or monitoring for a patient who was deliberately poisoned by fish other than ciguatera, scombroid, or shellfish. This would include scenarios like follow-up appointments for symptom management, laboratory re-evaluation, or counseling related to the assault.

• Ensure documentation clearly states the poisoning was an assault and not accidental or self-inflicted.
• Verify that the type of fish poisoning is not ciguatera, scombroid, or shellfish, as those have specific codes.
• Confirm this is a subsequent encounter, meaning the patient has already received initial care for this condition.
