Toxic effect of seafood, accidental (unintentional), init

This code signifies an adverse health event resulting from the unintentional ingestion of seafood other than fish, shellfish, or ciguatera-tainted fish. The patient is experiencing the initial phase of symptoms related to this toxic exposure.

Use this code for patients presenting with symptoms like nausea, vomiting, diarrhea, or neurological signs after accidentally consuming contaminated or spoiled seafood such as sea cucumber, sea urchin, or other less common marine organisms. This applies to the initial visit for diagnosis and treatment of the acute toxic effect.

• Ensure the documentation clearly states "accidental" or "unintentional" ingestion.
• Verify the specific type of seafood involved is not fish (T61.0-T61.2) or shellfish (T61.7).
• This "initial encounter" indicator is used for the entire period a patient is receiving active treatment for the toxic effect.
