Poisoning by immunoglobulin, accidental, init

This code signifies an adverse event where a patient has been unintentionally poisoned by an immunoglobulin product. This typically involves an overdose or an inappropriate administration of an immunoglobulin, leading to toxic effects. The poisoning is not due to a manufacturing defect or a known adverse drug reaction at therapeutic doses, but rather an error in administration.

Use this code when documentation clearly indicates an accidental overdose or incorrect administration of an immunoglobulin product resulting in a toxic reaction. This applies to initial encounters for treatment of the poisoning. Examples include a nurse administering a significantly higher dose than prescribed, or a patient accidentally self-administering too much immunoglobulin.

• Ensure the documentation specifies "accidental" or "unintentional" to differentiate from intentional overdose or adverse effects at therapeutic levels.
• Verify that the substance involved is an immunoglobulin; other biologicals would fall under different codes.
• Confirm this is the initial encounter for the poisoning; subsequent care would use the appropriate follow-up or sequela codes.
