Poisoning by mixed bact vaccines w/o a pertuss, acc, init

This code signifies an adverse reaction or poisoning resulting from the accidental administration of a multi-component bacterial vaccine that specifically excludes a pertussis component. This could involve an overdose, wrong vaccine, or other error leading to systemic effects beyond expected vaccine side effects.

Apply this code when a patient presents with symptoms of poisoning or an adverse event due to an unintentional exposure to a mixed bacterial vaccine (e.g., tetanus-diphtheria without pertussis) and it is the initial encounter for this specific poisoning. This would include situations like a medication error where the wrong vaccine was given or an excessive dose.

• Ensure the vaccine involved is a mixed bacterial vaccine and explicitly lacks a pertussis component.
• Confirm the poisoning was accidental (unintentional), not intentional self-harm or assault.
• This code is for the initial encounter for the poisoning; subsequent care would use a different seventh character.
