Immunization not carried out because of patient allergy to vaccine or component
ICD-10 Z28.04 is a billable code used to indicate a diagnosis of immunization not carried out because of patient allergy to vaccine or component.
Z28.04 is used when a patient is unable to receive a vaccine due to a documented allergy to the vaccine itself or one of its components. This code highlights the importance of understanding patient-specific factors that influence health outcomes, particularly in preventive care settings. Allergies can significantly impact immunization schedules, which are crucial for preventing infectious diseases. Social determinants of health, such as access to healthcare, education about allergies, and socioeconomic status, can also influence a patient's ability to receive vaccinations. Proper documentation of the allergy and the rationale for not administering the vaccine is essential for accurate coding and to ensure that patients receive appropriate preventive care and follow-up screenings.
Complete immunization records, allergy history, and patient education notes.
Routine checkups where immunizations are discussed, screenings for allergies, and aftercare follow-ups for patients with known allergies.
Consideration of social determinants such as access to allergist consultations and patient understanding of vaccine safety.
Population health data on vaccination rates, allergy prevalence, and community health assessments.
Epidemiological studies on vaccine-preventable diseases and community outreach programs addressing vaccine hesitancy due to allergies.
Tracking health disparities related to vaccination and allergy management in different populations.
Used when administering vaccines, but Z28.04 indicates a vaccine was not given due to allergy.
Document the reason for not administering the vaccine alongside the CPT code.
Primary care providers should ensure thorough allergy assessments are conducted.
Document the specific allergy, the vaccine affected, and any discussions with the patient regarding alternative immunization options. Ensure that this information is clearly noted in the patient's medical record to support the use of Z28.04.
