Which statement regarding HEDIS is NOT true?

The statement regarding HEDIS that is NOT true is that it is a division of the Centers for Medicare and Medicaid Services (CMS). HEDIS, which stands for Healthcare Effectiveness Data and Information Set, is actually developed and maintained by the National Committee for Quality Assurance (NCQA). It consists of standardized performance measures used to evaluate the quality of care and services provided by health plans. While CMS utilizes HEDIS measures in various programs to assess quality, it doesn't oversee or operate HEDIS as a division. Understanding this context clarifies why the statement indicating that HEDIS is a division of CMS is incorrect.

The other statements accurately describe HEDIS, including its purpose, development, and how it is used in quality assessment within the healthcare system.
