2025 ICD-10-CM code T50.A15

Adverse effect of pertussis vaccine, including combinations with a pertussis component.

The appropriate use of this code requires consideration of the specific adverse event and adherence to the official ICD-10-CM guidelines.Additional codes should be used to specify the nature of the adverse reaction.Always consult the most current coding manuals for clarification.

Medical necessity is established by the occurrence of an adverse effect following administration of the pertussis vaccine.The documentation should clearly link the temporality of the event to the vaccine administration and provide sufficient clinical detail to justify the diagnosis.

The clinical responsibility lies with the healthcare provider administering the vaccine and monitoring the patient for adverse reactions.This includes proper documentation of the vaccination, immediate management of any adverse events, and follow-up care as needed.

IMPORTANT Related codes might include those specifying the type of adverse reaction (e.g., allergic reaction, anaphylaxis) or additional codes from Chapter 20 (External causes of morbidity) to indicate the circumstances surrounding the event.T50.A15A, T50.A15D, and T50.A15S are also available for initial encounter, subsequent encounter, and sequela, respectively.

In simple words: This code is used when someone has a bad reaction to a pertussis (whooping cough) vaccine.This could be anything from a mild reaction to something more serious, and other codes will be used to describe the exact reaction.

This ICD-10-CM code classifies adverse effects resulting from the administration of a pertussis vaccine, encompassing both vaccines containing only pertussis and those combining pertussis with other components.The code captures a wide range of reactions, from mild to severe, stemming from the vaccine's administration.It's crucial to note that this code should be used in conjunction with additional codes to specify the nature of the adverse effect experienced by the patient.

Example 1: A 6-month-old infant receives the DTaP vaccine and develops a localized reaction at the injection site, characterized by redness, swelling, and mild pain.Code T50.A15 is used to indicate the adverse effect of the vaccine, and additional codes may be used to specify the nature and severity of the local reaction., A 2-year-old child experiences a severe allergic reaction (anaphylaxis) shortly after receiving the DTaP vaccine, requiring immediate medical intervention, including epinephrine administration.T50.A15 is used, along with codes for anaphylaxis and the specific treatment administered., A 5-year-old child receives a combined pertussis vaccine and develops a fever and generalized rash a few days later.T50.A15 is applied in conjunction with codes describing the fever and the rash.

Detailed documentation should include the date and time of vaccination, vaccine administered (including lot number), patient's medical history, description of the adverse event (onset, duration, symptoms), any interventions or treatment provided, and the outcome.This documentation is crucial for reporting and analysis of adverse events following immunization.

** This code is used for adverse effects related specifically to pertussis vaccines.It does not encompass adverse reactions to other types of vaccines.Always ensure that the most appropriate and specific codes are utilized to accurately reflect the patient's clinical presentation.
