Immunization not carried out because of caregiver refusal

Code Description

ICD-10 Z28.82 is a billable code used to indicate a diagnosis of immunization not carried out because of caregiver refusal.

Key Diagnostic Point:

Z28.82 is used when an immunization is not administered due to the refusal of the caregiver. This situation often arises in pediatric care, where parents or guardians may decline vaccinations for their children based on personal beliefs, misinformation, or concerns about vaccine safety. The refusal can significantly impact public health, as it contributes to lower immunization rates and increases the risk of vaccine-preventable diseases. Understanding the social determinants of health, such as education level, socioeconomic status, and access to healthcare information, is crucial in addressing these refusals. Preventive care strategies should include effective communication about the benefits and risks of immunizations, as well as addressing any misconceptions. Screening for vaccine hesitancy during routine visits can help healthcare providers identify families at risk of refusing immunizations and provide tailored education and support.
