Toxic effect of unsp noxious sub eaten as food, asslt, subs

This code signifies a toxic reaction resulting from an unknown harmful substance ingested as food, where the ingestion was an intentional act of harm by another person. It is used for encounters following the initial treatment of the poisoning.

Apply this code when a patient presents for follow-up care, monitoring, or treatment of complications stemming from food poisoning due to an unspecified substance, and the medical record clearly indicates the poisoning was an assault. This includes situations like ongoing symptoms, medication adjustments, or psychological support after the initial acute phase.

• Ensure documentation explicitly states the toxic substance was "unspecified" and "eaten as food."
• Verify the encounter is for a "subsequent encounter" and not the initial treatment.
• Confirm the intent was an "assault" as documented by the provider.
