Poisoning by immunoglobulin, undetermined, subs encntr

This code signifies a patient experiencing an adverse effect from an immunoglobulin product, where the specific intent (e.g., accidental, intentional self-harm) is not documented. It indicates that the patient is receiving active treatment for the poisoning, or the sequelae of the poisoning, after the initial encounter.

This code is appropriate for follow-up visits or hospitalizations where a patient is being treated for the ongoing effects of an immunoglobulin poisoning, and the circumstances surrounding the poisoning are unknown or unspecified. This includes situations where the patient is admitted for complications or requires continued management of the toxic effects.

• Always assign an additional code for the specific adverse effect or manifestation of the poisoning.
• Ensure documentation clearly supports an "undetermined" intent; if intent is known (accidental, intentional), use the appropriate specific intent code.
• Verify that the encounter is indeed "subsequent," meaning the patient has already received initial treatment for the poisoning.
