Poisn by pertuss vaccine, inc combin w pertuss, asslt, subs

This code signifies a patient experiencing an adverse reaction or toxic effect due to the administration of a pertussis-containing vaccine, where the vaccine was intentionally given to cause harm. This specific code is used for follow-up care after the initial poisoning event.

Apply this code when documenting subsequent encounters for a patient who has been poisoned by a pertussis vaccine, including combination vaccines, as a result of an assault. This would include follow-up appointments for monitoring, managing persistent symptoms, or addressing complications arising from the initial poisoning.

• Always assign an additional code for the specific manifestation of the poisoning (e.g., rash, fever, neurological symptoms).
• Ensure documentation clearly indicates the "assault" intent and that this is a "subsequent encounter" for the poisoning.
• Distinguish from accidental poisoning or adverse effects occurring in a therapeutic setting, which would use different codes.
