Poisoning by oth agents aff GI sys, assault, sequela

This code signifies a long-term or residual effect resulting from a deliberate act of poisoning with a substance that primarily targets the gastrointestinal system. The initial poisoning event was an assault, and the patient is now presenting with ongoing health issues directly attributable to that past event.

Use this code when documenting a patient presenting with chronic gastrointestinal symptoms, organ damage, or other lasting health problems that are a direct consequence of a past poisoning assault involving agents like certain heavy metals, pesticides, or corrosive substances ingested with intent to harm. This code is appropriate for follow-up visits or when the sequela is the primary reason for the encounter, long after the acute poisoning has resolved.

• Always sequence this code after the code for the specific sequela (e.g., chronic gastritis, esophageal stricture).
• Ensure documentation clearly links the current condition to a past poisoning assault.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
