Scombroid fish poisoning, intentional self-harm, sequela

This code signifies the long-term or residual effects resulting from a past episode of scombroid fish poisoning that was intentionally self-inflicted. Scombroid poisoning is an allergic-type reaction to histamine in improperly stored fish, manifesting with symptoms like flushing, headache, palpitations, and gastrointestinal distress. The "sequela" aspect indicates that the current patient encounter addresses a chronic or lasting health issue directly attributable to that prior self-harm event.

Apply this code when a patient presents for treatment of a persistent health problem, such as chronic neurological issues, ongoing dermatological conditions, or other lasting organ damage, that is documented as a direct consequence of a previous, self-inflicted scombroid fish poisoning. This code is appropriate for follow-up care related to the long-term impact, not the acute poisoning event itself. It should be used when the acute phase of the poisoning has passed, and the current encounter addresses the lingering effects.

• Always sequence this code after the specific code(s) for the sequela being treated (e.g., chronic urticaria, neurological deficit).
• Ensure documentation clearly links the current condition to a past episode of intentional self-harm scombroid poisoning.
• Do not use this code for acute poisoning or for accidental/unspecified poisoning; the "intentional self-harm" and "sequela" components are critical.
