Toxic effect of other seafood, assault, sequela

This code signifies the long-term or residual effects resulting from a toxic reaction to seafood other than fish, shellfish, or ciguatera, where the exposure was due to an intentional act of harm (assault). These sequelae could include chronic neurological issues, persistent gastrointestinal problems, or other lasting organ damage.

Apply this code when documenting a patient presenting with ongoing health problems directly attributable to a past incident of seafood poisoning (excluding fish, shellfish, or ciguatera) that was inflicted as an assault. This code is appropriate for follow-up visits addressing the chronic manifestations of such an event, after the acute phase has passed.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past toxic effect from other seafood and specifies the assault intent.
• Do not use for acute poisoning; this code is specifically for sequelae.
