Toxic effect of noxious substnc eaten as food, asslt, sqla

This code signifies a long-term or residual effect resulting from the intentional ingestion of a harmful, non-food substance. The substance is not typically classified as a drug or common poison but is specified as a noxious agent. This code is used when the acute phase of the poisoning has passed, and the patient is experiencing ongoing health issues directly attributable to the past ingestion.

Apply this code for follow-up encounters or when documenting chronic conditions stemming from a past assault where the patient was forced or tricked into eating a specified noxious substance. This is appropriate for conditions like persistent gastrointestinal issues, organ damage, or neurological sequelae that developed after the initial toxic event. Do not use for acute poisoning or for substances not specified as noxious.

• Always use in conjunction with a code for the specific sequela (e.g., chronic gastritis, liver damage).
• Ensure documentation clearly states the ingestion was an assault and specifies the noxious substance.
• Verify the encounter is for a sequela and not an acute toxic effect, which would require a different code.
