Poisoning by antipruritics, intentional self-harm, subs

This code signifies a patient presenting for follow-up care or sequelae resulting from an intentional self-poisoning event involving an antipruritic medication. The initial acute phase of the poisoning has passed, and the patient is now being managed for ongoing effects or complications.

Apply this code when documenting subsequent encounters for patients who previously attempted self-harm by ingesting or otherwise misusing antipruritic drugs. This includes visits for ongoing medical management of organ damage, psychological evaluation, or monitoring of recovery after the initial acute poisoning treatment.

• Always assign an additional code for the specific antipruritic drug involved, if known.
• Ensure the "D" seventh character is used for subsequent encounters, indicating ongoing care after the initial treatment.
• Do not use this code for the initial acute poisoning event; use the "A" seventh character for those encounters.
