Learn the importance of collecting data on social determinants of health (SDOH) with Z Codes
What are Z Codes?

SDOH-related Z codes range from ICD-10-CM categories Z55-Z65 and are used to document SDOH data (e.g., food insecurity, housing, lack of transportation).
Z codes refer to factors influencing health status or reasons for contact with health services that cannot be classified elsewhere as diseases, injuries or external causes.
What are SDOHs and why collect them?
SDOH are the conditions in the environment where people are born, live, learn, work, play, worship, and age that affect a wide range of health and quality of life outcomes and risks.
The World Health Organization (WHO) estimates that SDOH accounts for 30-55% of health outcomes.
SDOH revenue can improve equity in health care delivery and research by:
Empower providers to identify and address health disparities (e.g., care coordination and referrals)
Support quality measurement
Support the planning and implementation of social needs interventions
Identify the needs of the community and population
Monitor the effectiveness of the SDOH intervention for patient outcomes
Use data to advocate for updating and create new policies
Using Z Codes for SDOH

SDOH information can be collected before, during, or after a healthcare encounter through structured health risk assessments and screening tools.
These codes should be assigned only when documentation specifies that the patient has an associated problem or risk factor that influences the patient's health.
SDOH information can be collected through person-provider interaction or self-reported, as long as it is signed and incorporated into the medical record by a clinician or provider.
Z Code Update

New SDOH Z codes can go into effect every April 1 and October 1. New codes are announced ahead of their effective date on the CDC website .
Use the CDC National Center for Health Statistics to search for all available Z codes. Available at this link .
Join the public process for the development and approval of SDOH codes through the ICD-10-CM Coordination and Maintenance Committee.
