Poisoning by antitussives, intentional self-harm, subs

This code signifies a patient presenting for follow-up care or treatment of complications arising from an intentional overdose of antitussive medications. The initial self-harm event has already occurred, and the current encounter addresses ongoing issues related to that poisoning.

Apply this code when a patient is seen for continued management of organ damage, psychological evaluation, or other sequelae after an intentional antitussive poisoning. This includes situations like follow-up appointments for liver function monitoring, psychiatric counseling, or treatment of aspiration pneumonia that developed as a result of the overdose.

• Ensure documentation clearly states "intentional self-harm" and that this is a subsequent encounter.
• Always sequence this code after any codes for the specific manifestations or complications of the poisoning.
• Do not use for the initial acute poisoning event; that would require an initial encounter (A) or subsequent encounter (D) if the patient is still receiving active treatment for the acute phase.
