Poisoning by oth agents aff GI sys, accidental, sequela

This code signifies a long-term health problem or complication arising from an accidental ingestion or exposure to a substance that primarily damaged the gastrointestinal system. The initial poisoning event has resolved, but its lasting effects on the digestive tract are still present.

Apply this code when a patient presents with chronic gastrointestinal symptoms, such as persistent malabsorption, strictures, or chronic inflammation, that are directly attributable to a past, unintentional poisoning by a substance affecting the GI system. This code is appropriate for documenting the sequelae of such an event, not the acute poisoning itself.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., K90.9 for intestinal malabsorption, unspecified).
• Ensure documentation clearly links the current GI condition to a past accidental poisoning event.
• Do not use this code for acute poisoning events; instead, refer to the acute poisoning codes within the T47 category.
