Poisoning by immunoglobulin, accidental, sequela

This code signifies a long-term or residual effect resulting from an accidental or unintentional overdose or adverse reaction to an immunoglobulin product. This could involve persistent symptoms, organ damage, or other lasting complications that developed after the initial poisoning event.

Apply this code when documenting a patient presenting with a current condition directly attributable to a past, unintended poisoning by an immunoglobulin. This is appropriate for follow-up visits where the sequela is being managed, or when the long-term impact of the poisoning is being addressed.

• Always sequence the code for the specific sequela (e.g., kidney failure, neuropathy) first, followed by this code.
• Ensure documentation clearly links the current condition to a past accidental immunoglobulin poisoning.
• Do not use for acute poisoning events; this code is exclusively for sequelae.
