This video reviews the Mapping Medicare Disparities (MMD) Tool, developed by the CMS Office of Minority Health. It is an interactive mapping tool that allows users to identify areas of disparities between Medicare sub-groups (e.g., by race and ethnicity, age, sex, and dual eligibility status) in health outcomes, utilization, and spending. This information provides a starting point for understanding health-related data geographically and may be used to target populations for potential interventions.
