Code Description

ICD-10 Z02.84 is a billable code used to indicate a diagnosis of encounter for child welfare exam.

Key Diagnostic Point:

Z02.84 is used to document encounters specifically for child welfare examinations, which are often mandated by child protective services or other governmental agencies. These examinations assess the child's physical and emotional well-being, ensuring that they are safe and healthy in their living environment. The examination may include screenings for developmental milestones, mental health assessments, and evaluations of social determinants of health such as housing stability, family dynamics, and access to healthcare. Preventive care is a critical component, as these exams can identify potential issues early, allowing for timely interventions. The social context of these encounters is significant, as they often involve children from vulnerable populations who may be at risk due to socioeconomic factors. Proper documentation is essential to capture the complexity of these encounters, including any referrals made for additional services or follow-up care.
