Poisoning by other and unspecified bacterial vaccines

This code signifies an adverse reaction or toxic effect resulting from the administration of a bacterial vaccine not specifically categorized elsewhere. It indicates a patient experiencing symptoms of poisoning due to the vaccine itself, rather than an allergic reaction or an infectious complication from the vaccine.

Use this code when documentation clearly states a patient is suffering from poisoning due to a bacterial vaccine, such as tetanus toxoid, diphtheria toxoid, or pertussis vaccine, and the specific vaccine is not otherwise classified. This code is appropriate when the adverse effect is directly attributable to the vaccine's toxic properties or an overdose, rather than an immune response.

• Always sequence this code as a principal diagnosis when the poisoning is the primary reason for the encounter.
• Do not use this code for allergic reactions to vaccines; refer to codes in the 995.2x series for those scenarios.
• Ensure documentation specifies "poisoning" or "toxic effect" from a bacterial vaccine, not just a general adverse effect or complication.
