Poisoning by digestants, undetermined, subsequent encounter

This code signifies a poisoning event caused by digestants where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is receiving follow-up care for the sequelae or complications of this poisoning, not the initial acute treatment.

Apply this code when a patient presents for ongoing management of symptoms or conditions resulting from an undetermined digestant poisoning. This would include situations like follow-up appointments for organ damage, persistent gastrointestinal issues, or other chronic effects after the initial acute phase has passed.

• Ensure the encounter is for subsequent care, not the initial treatment of the poisoning.
• Confirm that the documentation explicitly states "undetermined" intent for the digestant poisoning.
• Always code any associated manifestations or complications of the poisoning in addition to this code.
