A tool that more than 90 percent of America’s health plans use to measure performance on important dimensions of care and service. HEDIS consists of 71 measures across eight domains of care. Because so many plans collect HEDIS data and because the measures are so specifically defined, HEDIS makes it possible to compare the performance of health plans on an “apples-to-apples” basis.
Health plans also use HEDIS results themselves to see where they need to focus their improvement efforts.
