Poisoning by plague vaccine

This code signifies an adverse reaction or toxic effect resulting from the administration of a plague vaccine. It indicates that the patient has experienced symptoms or complications directly attributable to the vaccine itself, rather than the disease it prevents.

Apply this code when documentation clearly states a patient's illness or symptoms are due to poisoning by plague vaccine. This includes allergic reactions, systemic toxicity, or other adverse effects directly linked to the vaccine. Supporting documentation should detail the vaccine administered and the resulting clinical manifestations.

• Always sequence this code as a primary diagnosis when it is the reason for the encounter.
• Consider adding an E-code (E948.0 for adverse effects of bacterial vaccines) to further specify the external cause.
• Differentiate from allergic reactions to other vaccines or general adverse effects of therapeutic drugs.
