Poisoning by immunoglobulin, assault, subsequent encounter

This code indicates a poisoning event resulting from the administration of immunoglobulin, where the poisoning was intentionally inflicted by another person. It specifically applies to encounters following the initial treatment of the poisoning, such as follow-up visits or management of ongoing complications.

Use this code for patients presenting for ongoing care related to an immunoglobulin poisoning that was determined to be an assault. This includes situations where the patient is being monitored for adverse effects, receiving treatment for lingering symptoms, or undergoing psychological support due to the intentional nature of the poisoning.

• Always assign an additional code for the specific adverse effect or manifestation of the poisoning.
• Ensure documentation clearly supports the "assault" intent and that the encounter is not the initial treatment.
• Distinguish from accidental poisoning (T50.Z11-) or self-harm (T50.Z12-).
