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

This code signifies a patient presenting for follow-up care related to a previous act of intentional self-harm involving an overdose or toxic exposure to a substance that primarily impacts the digestive system. The patient is no longer in the acute phase of the poisoning but is receiving ongoing management or evaluation for its effects.

This code is appropriate for subsequent encounters such as follow-up appointments, medication adjustments, or monitoring for long-term complications after the initial treatment for an intentional self-poisoning by a gastrointestinal agent. It applies when the patient is seen for issues directly stemming from the initial self-harm event, not for the acute poisoning itself.

• Always sequence this code after the primary diagnosis for the specific effects or complications of the poisoning.
• Ensure documentation clearly indicates "intentional self-harm" and that the encounter is "subsequent."
• Verify the substance involved primarily affects the gastrointestinal system; otherwise, a different T47 subcategory may be more appropriate.
