Poisn by pertuss vaccine, inc combin w pertuss, acc, sqla

This code signifies a long-term health problem or complication arising from an accidental overdose or improper administration of a pertussis-containing vaccine. It indicates that the initial poisoning event has resolved, but the patient is still experiencing residual effects.

Use this code when documenting a patient presenting with a chronic condition or sequela directly attributable to an unintentional poisoning by a pertussis vaccine. This includes situations where the patient received an incorrect dose, an expired vaccine, or an inappropriate route of administration, leading to lasting adverse effects.

• This "S" code indicates a sequela, meaning it should be used for the residual effects of the poisoning, not the acute event.
• Always sequence the sequela code first, followed by codes for the specific manifestations of the sequela.
• Ensure documentation clearly links the current condition to the past pertussis vaccine poisoning.
