The Centers for Medicare & Medicaid Services (CMS) Office of Minority Health (OMH) released a new Z code infographic: Improving the Collection of Social Determinants of Health (SDOH) Data with ICD-10-CM Z Codes.

CMS Z Code InfographicThis resource aims to assist providers with understanding and using Z codes to improve the quality and collection of health equity data. Using social determinants of health, Z codes can enhance quality improvement activities, track factors that influence people’s health and provide further insight into existing health inequities.

Z codes are a set of ICD-10-CM codes used to report social, economic, and environmental determinants known to affect health and health-related outcomes. Nine broad categories of Z codes represent various hazardous socioeconomic, and environmental conditions. Z codes can be used in any health setting and by any provider as a tool for identifying a range of issues related to education and literacy, employment, housing, ability to obtain adequate amounts of food or safe drinking water, and occupational exposure to toxic agents, dust or radiation.
