Poisoning by immunoglobulin, undetermined, sequela

This code describes the long-term effects or complications arising from a past poisoning event involving immunoglobulin, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. It signifies a residual condition or chronic problem directly attributable to the previous adverse exposure to immunoglobulin.

Use this code when documenting a current health problem that is a direct consequence of a prior, unspecified immunoglobulin poisoning. This would apply in situations where a patient presents with a chronic organ dysfunction, neurological deficit, or other lasting sequela, and the medical record clearly links it to an earlier immunoglobulin poisoning event whose intent remains unknown.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, neuropathy).
• Ensure documentation explicitly states the link between the current condition and the past immunoglobulin poisoning.
• Only use this code when the intent of the poisoning is truly undetermined; otherwise, use the appropriate intent-specific sequela code.
