Poisoning by oth agents aff GI sys, assault, subs

This code signifies a patient presenting with adverse effects from a toxic substance, other than those specifically categorized, that primarily targets the digestive system. The poisoning was intentionally inflicted by another person, and this encounter represents follow-up care after the initial treatment.

Apply this code for patients receiving ongoing management or evaluation for gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea, abdominal pain) resulting from an intentional poisoning by an unspecified or "other" agent. This is appropriate when the patient is seen for a subsequent visit related to the initial assault.

• Ensure the documentation clearly states the poisoning was an assault and that this is not the initial encounter for treatment.
• Verify the primary system affected is the gastrointestinal system; if other systems are primarily affected, a different T47 subcategory may be more appropriate.
• Always sequence this code after any codes for the specific manifestations of the poisoning.
