Poisoning by oth agents aff GI sys, assault, init

This code signifies a deliberate act of poisoning where a substance, not otherwise specified but primarily impacting the digestive system, was administered with malicious intent. The patient is in the initial phase of receiving care for the acute effects of this poisoning.

Apply this code when a patient presents with symptoms of gastrointestinal distress (e.g., nausea, vomiting, abdominal pain, diarrhea) confirmed to be due to poisoning by an unknown or unclassifiable agent, and the medical record clearly documents the poisoning as an assault. This is appropriate for the initial hospital visit or first encounter with a healthcare provider for this specific event.

• Ensure documentation explicitly states the poisoning was an assault and the primary system affected is gastrointestinal.
• Use an additional code to identify the specific toxic agent if known and documented.
• Verify this is the patient's first encounter for this particular poisoning episode; subsequent encounters would require a different seventh character.
