Ciguatera fish poisoning, accidental (unintentional), init

This code signifies an acute illness resulting from the consumption of fish contaminated with ciguatoxins, which are naturally occurring toxins produced by marine dinoflagellates. Symptoms typically involve a combination of gastrointestinal, neurological, and cardiovascular manifestations, varying in severity depending on the amount of toxin ingested and individual susceptibility.

This code is appropriate for documenting the initial presentation and treatment of a patient diagnosed with ciguatera poisoning due to accidental ingestion of contaminated fish. It should be used when the patient is receiving active treatment for the acute effects of the poisoning.

• Ensure documentation clearly states accidental ingestion of fish and the resulting ciguatera poisoning.
• This "initial encounter" seventh character is used for the period when the patient is receiving active treatment for the condition.
• Consider additional codes for specific symptoms or complications (e.g., bradycardia, paresthesia) if documented.
