Ciguatera fish poisoning, undetermined, subsequent encounter

This code signifies a diagnosis of ciguatera fish poisoning where the intent (e.g., accidental, intentional self-harm, assault) is unknown or unspecified. It specifically applies to encounters following the initial treatment of the poisoning, indicating ongoing care or follow-up for residual symptoms.

This code is appropriate for subsequent visits when a patient is receiving continued management for ciguatera fish poisoning, and the circumstances surrounding the poisoning remain undetermined. Examples include follow-up appointments for persistent neurological symptoms, gastrointestinal issues, or cardiovascular effects after the initial acute phase.

• Only use this code for subsequent encounters after the initial diagnosis and treatment.
• Ensure documentation clearly states the undetermined intent of the poisoning.
• Pair with additional codes for specific symptoms or complications of the ciguatera poisoning.
