Poisn by mixed bact vaccines w/o a pertuss, self-harm, subs

This code signifies an adverse effect resulting from the deliberate self-administration of a bacterial vaccine that does not contain a pertussis component. The patient intentionally caused this poisoning, and the encounter documented is for follow-up care after the initial injury or poisoning.

Apply this code when a patient presents for ongoing management or evaluation of complications stemming from a self-inflicted poisoning by a non-pertussis bacterial vaccine. This includes scenarios such as monitoring for lingering side effects, treating persistent symptoms, or addressing secondary infections related to the initial intentional overdose.

• Always assign an additional code for the specific adverse effect or manifestation of the poisoning.
• Ensure documentation clearly indicates "intentional self-harm" and that the encounter is "subsequent."
• Verify the vaccine administered was a bacterial vaccine and explicitly lacked a pertussis component.
