Poisoning by immunoglobulin, undetermined, initial encounter

This code signifies an adverse reaction or toxicity resulting from the administration of an immunoglobulin product, where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is presenting for the initial treatment of this poisoning event.

Apply this code when a patient experiences an adverse effect from an immunoglobulin, and documentation does not specify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the first encounter related to the management of these symptoms.

• Ensure documentation clearly states the substance involved is an immunoglobulin and the intent is "undetermined."
• Always assign an additional code for the specific manifestation(s) of the poisoning, if known.
• Verify this is the patient's first presentation for this particular poisoning episode.
