Poisoning by dietetics

This code signifies an adverse reaction or toxic effect resulting from the ingestion or exposure to substances intended for dietary purposes, such as vitamins, minerals, food supplements, or other dietetic preparations. It encompasses both accidental and intentional poisonings where these substances cause harm beyond their intended nutritional or therapeutic effects.

Apply this code when documentation clearly indicates a patient's illness, injury, or adverse event is directly attributable to an overdose, misuse, or toxic reaction to a dietetic agent. This includes scenarios like excessive vitamin intake leading to hypervitaminosis, mineral toxicity from supplements, or adverse effects from herbal diet aids. Documentation should specify the dietetic substance involved and the resulting clinical manifestations.

• Always code the specific substance responsible for the poisoning using an E-code (E850-E869) in addition to this diagnosis code.
• Distinguish from adverse effects of therapeutic drugs (995.2x) or accidental poisoning by other medications (E850-E858).
• Ensure documentation specifies "poisoning" or "toxic effect" rather than just an adverse reaction to a correctly administered substance.
