Poisoning by oth agents aff GI sys, self-harm, sequela

This code signifies a long-term consequence or complication arising from a past intentional self-poisoning event involving substances that primarily affect the gastrointestinal system. These sequelae are chronic conditions or permanent injuries directly attributable to the original self-harm act.

Apply this code when documenting conditions such as esophageal strictures, chronic gastritis, or malabsorption syndromes that developed as a direct result of a previous self-inflicted poisoning by agents like corrosive chemicals or certain medications primarily targeting the GI tract. This code is for use after the acute phase of the poisoning has passed.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past intentional self-harm poisoning event.
• Distinguish from acute poisoning events, which would use an acute poisoning code, not a sequela code.
