Data, Measurement and Equity
To improve equity, first measure it.
Stratifying HEDIS Measures By Race & Ethnicity
Stratifying HEDIS measures is part of NCQA’s commitment to include health equity in all offerings. New for measurement year 2025, a total of 23 HEDIS measures can be stratified by race and ethnicity.
Why stratify?
Because better transparency into health plan performance by race and ethnicity will help quality advocates and health equity champions understand:
- Where disparities exist, so we can address care gaps.
- Where disparities don’t exist, so the industry can learn from top performers.
To learn more about how health plans can improve collection and management of race and ethnicity data, view the on-demand webinar or explore the Race and Ethnicity Stratification Learning Network.
How does stratification work within HEDIS measures?
- Align race and ethnicity reporting with Office of Management and Budget categories.
- Include options for “declined” if a member chooses not to provide race or ethnicity.
- Stratify separately by race and ethnicity.
