Toxic effect of berries and other plants eaten as food

This code signifies an adverse systemic reaction resulting from the ingestion of berries or other plant matter typically consumed as food, which are inherently toxic. This includes poisoning from wild berries, mushrooms, or other plants mistaken for edible varieties, leading to symptoms such as gastrointestinal distress, neurological effects, or other systemic toxicity.

Assign this code when documentation clearly indicates a patient's illness or injury is directly attributable to the toxic effects of ingesting poisonous berries or other plants commonly mistaken for food. This typically applies to accidental poisonings rather than intentional self-harm. Supporting documentation should detail the ingested substance and the resulting clinical manifestations.

• Differentiate from allergic reactions to edible foods; this code is for inherent toxicity.
• Always sequence as a primary diagnosis when it is the reason for the encounter.
• Consider an E-code (E865.0-E865.9) to specify the external cause of poisoning, if available.
