In simple words: This code indicates a long-term health problem that is the result of a bad reaction to a whooping cough vaccine, or a combination vaccine that includes the whooping cough vaccine.

This code represents the long-term consequences or sequelae resulting from an adverse effect of a pertussis vaccine, including combinations containing a pertussis component.A sequela is a condition that is the consequence of a previous disease or injury.

Example 1: A patient received a DTaP vaccine as a child and subsequently developed epilepsy, which is now considered a sequela of the vaccine., A patient experiences long-term neurological deficits following an adverse reaction to a pertussis-containing vaccine, requiring ongoing physical therapy and supportive care., A child develops a persistent developmental delay following an adverse reaction to a DTaP vaccine, which is now documented as a long-term sequela.

Documentation should clearly establish the causal relationship between the pertussis vaccine and the sequela. This may include the initial reaction to the vaccine, the time course of the development of the sequela, and supporting medical records and specialist consultations. Details of the specific sequela and its impact on the patient's function and quality of life should also be documented.

** It is essential to distinguish between the acute adverse effects of the pertussis vaccine and the long-term sequelae.This code is specifically for the sequelae, and other codes would be used to document the initial adverse reaction.Refer to the iFrameAI product for the latest information.
