Poisoning by immunoglobulin, intentional self-harm, sequela

This code describes the long-term effects or complications arising from a deliberate act of self-poisoning using an immunoglobulin. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience residual health issues directly attributable to that event.

Use this code when documenting conditions such as chronic organ damage, neurological deficits, or persistent immune system dysregulation that are a direct result of a past intentional self-harm overdose of an immunoglobulin. This applies when the patient is no longer in the acute phase of the poisoning but is being treated for its lasting consequences.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past intentional self-harm poisoning by immunoglobulin.
• Do not use this code for acute poisoning; refer to the appropriate acute poisoning codes for initial encounters.
