Toxic effect of unsp noxious sub eaten as food, asslt, init

This code signifies a patient presenting with adverse effects from ingesting an unknown harmful substance that was consumed as food, resulting from an intentional act of assault. The "initial encounter" indicates that this is the first time the patient is receiving treatment for this specific poisoning event.

Use this code when documentation clearly states a toxic effect from an unspecified substance ingested as food, where the intent is explicitly documented as assault. This is appropriate for the initial visit to an emergency department or physician's office for evaluation and treatment of the acute poisoning.

• Always sequence this code first when it represents the primary reason for the encounter.
• Do not use if the substance is known or if the intent is accidental, suicidal, or undetermined.
• Requires thorough documentation of the assaultive nature of the ingestion and the initial phase of care.
