Toxic effect of noxious substnc eaten as food, acc, sequela

This code signifies a long-term or residual condition resulting from an accidental poisoning due to ingesting a harmful substance not typically considered food. The original toxic exposure, which was unintentional, has led to lasting health problems. This category excludes food poisoning from bacteria or viruses.

Apply this code when documenting a chronic health issue directly attributable to a past, accidental ingestion of a non-food noxious substance. Examples include persistent neurological damage from accidental lead paint chip ingestion, or chronic organ dysfunction following unintentional consumption of a poisonous plant. This code is used after the acute phase of the poisoning has resolved.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela.
• Ensure documentation clearly links the current condition to a past, accidental ingestion of a non-food substance.
• Distinguish from foodborne illnesses (e.g., bacterial food poisoning) which have different coding pathways.
