Poisoning by mixed bacterial vaccines, except combinations with a pertussis component

This code signifies an adverse reaction or poisoning resulting from the administration of a bacterial vaccine that contains a mixture of bacterial components, excluding any vaccines that also include a pertussis (whooping cough) component. This typically involves systemic or localized toxic effects rather than an allergic reaction.

Use this code when documentation clearly indicates a patient experienced poisoning from a multi-component bacterial vaccine, such as certain typhoid or cholera vaccines, where pertussis is explicitly absent from the vaccine formulation. This code is appropriate for reactions like fever, malaise, or severe local reactions attributed to the vaccine's toxic properties.

• Always review vaccine documentation to confirm the exact components and rule out the presence of a pertussis component.
• Distinguish poisoning from allergic reactions (e.g., anaphylaxis), which would be coded differently.
• Sequence this code as a secondary diagnosis when the primary reason for the encounter is the management of the poisoning symptoms.
