Toxic effect of noxious substnc eaten as food, assault, init

This code signifies a patient presenting with an adverse physiological reaction due to ingesting a harmful substance not typically considered food, where the exposure was intentionally inflicted by another party. The toxic effect is from a substance other than those specifically classified elsewhere (e.g., poisonous plants, seafood toxins). This code is for the initial phase of treatment.

Apply this code when a patient experiences acute symptoms of poisoning after consuming a non-food substance, such as a chemical or drug, that was deliberately administered to them by another person. This is appropriate for the initial evaluation and management of such an event in an emergency department or inpatient setting.

• Always assign an additional code for the specific toxic substance ingested, if known.
• Ensure documentation clearly indicates the substance was "eaten as food" (ingested) and that the exposure was an "assault."
• This "initial encounter" indicator (A) is used for the period when the patient is receiving active treatment for the toxic effect.
