HEDIS® Audits


Since its introduction in 1993, the Healthcare Effectiveness Data and Information Set (HEDIS®) has evolved to become the gold standard in health plan performance measurement. HEDIS is a set of performance measurements or indicators used to compare organizations “apples-to-apples” in terms of quality or value rather than price. In general, HEDIS is important to employers, government agencies, and consumers who wish to compare various organizations within a market. HEDIS performance is an integral component of CMS Stars rating, NCQA plan accreditation, Health Exchange scoring, and incentive programs for Medicaid plans.
