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

This code signifies a long-term or late effect resulting from the ingestion of an unspecified noxious substance, other than those specifically categorized, that was consumed as food. The initial intent of the exposure (accidental, intentional self-harm, assault) cannot be determined.

Apply this code when documentation indicates a residual condition or complication arising from a past toxic ingestion of an unidentifiable food-borne substance, and the original incident's intent is unknown. This is used after the acute phase of the poisoning has resolved.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly supports the "undetermined" intent and that the substance was ingested as food.
• Confirm that the patient is presenting for treatment of a chronic or residual effect, not the acute poisoning.
