Toxic effect of unsp seafood, undetermined, init encntr

This code signifies a patient presenting with adverse health effects due to consuming seafood, where the specific type of seafood causing the reaction is unknown. The intent of the exposure (e.g., accidental, intentional self-harm) is also undetermined. This code is used for the initial phase of treatment for such an event.

Apply this code when a patient experiences symptoms like nausea, vomiting, diarrhea, or allergic reactions after eating seafood, but the medical documentation does not specify which type of seafood was ingested. It is appropriate when the clinician cannot ascertain if the exposure was accidental, intentional, or due to assault. This code is only for the first encounter for this specific toxic effect.

• Ensure documentation clearly states "unspecified seafood" and "undetermined intent" to support this code.
• Do not use if the type of seafood is known (e.g., ciguatera, scombroid poisoning); instead, use a more specific code.
• For subsequent encounters related to the same toxic effect, use the appropriate seventh character (e.g., D for subsequent, S for sequela).
