Toxic effect of oth seafood, intentional self-harm, sequela

This code signifies a long-term consequence or residual condition resulting from a past poisoning by seafood other than ciguatera or scombroid, where the exposure was deliberately self-inflicted. It indicates that the acute toxic event has resolved, but the patient continues to experience related health issues.

Apply this code when documenting a chronic or residual health problem directly attributable to a prior intentional self-poisoning with unspecified seafood. This would be used in follow-up encounters after the initial acute toxic event has passed and the patient is being treated for lasting effects.

• Requires a seventh character "S" for sequela, indicating a late effect.
• Ensure documentation clearly links the current condition to the past intentional seafood poisoning.
• Do not use for acute poisoning; this code is exclusively for residual conditions.
