Ciguatera fish poisoning, assault, initial encounter

This code signifies a diagnosis of ciguatera fish poisoning resulting from an intentional act of harm by another person. The patient is in the acute phase of treatment for the poisoning and its immediate effects. Ciguatera poisoning is caused by consuming fish contaminated with ciguatoxins, leading to gastrointestinal, neurological, and cardiovascular symptoms.

Apply this code when a patient presents with symptoms of ciguatera fish poisoning, and medical documentation clearly indicates the poisoning was inflicted as an assault. This code is appropriate for the initial visit or encounter where the poisoning is being evaluated and treated.

• Ensure documentation explicitly states "assault" or "intentional harm" as the cause of the poisoning.
• Verify this is the patient's first encounter for this specific poisoning episode.
• Code additional symptoms or complications of ciguatera poisoning separately.
