Poisoning by immunoglobulin, intentional self-harm, subs

This code signifies a poisoning event resulting from the deliberate self-administration of an immunoglobulin, with the intent to cause harm. It specifically applies to encounters following the initial treatment of the poisoning, such as follow-up visits or management of complications.

Apply this code for patients presenting for ongoing care related to an immunoglobulin poisoning that was intentionally self-inflicted. This includes scenarios like managing organ damage, psychological follow-up for the self-harm attempt, or monitoring for delayed adverse effects after the acute phase has passed.

• Always sequence this code after the primary diagnosis for the specific adverse effect or complication of the poisoning.
• Requires an additional code from Chapter 20 (External Causes of Morbidity) to indicate the intent and circumstances of the self-harm.
• Distinguish from "initial encounter" (A) or "sequela" (S) based on the patient's current stage of treatment for the poisoning.
