Oth fish poisoning, accidental (unintentional), subs encntr

This code signifies a diagnosis of poisoning resulting from the ingestion of fish, excluding ciguatera or scombroid poisoning, where the exposure was accidental. It specifically indicates that the patient is receiving follow-up care for the initial poisoning event, such as monitoring for lingering symptoms or managing complications.

Use this code for patients presenting for subsequent evaluation or treatment of symptoms related to an accidental fish poisoning that is not otherwise specified. This includes scenarios where the patient is returning for a check-up after initial discharge, or for ongoing management of residual effects from the poisoning.

• Ensure documentation clearly states the poisoning was accidental and due to fish, but not ciguatera or scombroid.
• Confirm the encounter is for follow-up care, not the initial acute treatment, to justify the "D" seventh character.
• Always code any specific symptoms or complications of the poisoning in addition to this code.
