If a patient has social needs documented using ICD-10 Z codes, what is the primary purpose?

• A. Billing only
• B. Scheduling appointments
• C. Prescription management
• D. Coordination of care and tracking population needs

Answer: (D)

ICD-10 Z codes document social determinants of health—nonmedical factors that can affect a patient’s care. The main aim is to help the care team coordinate services and track needs across a population. By recording factors like housing instability, food insecurity, or transportation barriers, clinicians can connect patients with appropriate resources, plan targeted interventions, and monitor outcomes for groups of patients. It isn’t primarily about billing, scheduling, or medication management, even though Z codes may appear on claims; their core purpose is to support care coordination and population health monitoring.
