HEDIS Data Submission

NCQA collects HEDIS data directly from Health Plan Organizations and Preferred Provider Organizations for multiple purposes via the Healthcare Organization Questionnaire (HOQ) and HEDIS non-survey data through the Interactive Data Submission System (IDSS). The links below provide important information concerning the data submission process. All HEDIS data collected by NCQA are maintained in a central database with strict controls to protect confidentiality.

HEDIS data collected by NCQA are important for researchers working to improve the health care system, as well as for NCQA staff seeking to improve the HEDIS measures themselves. Commercial HEDIS data are used to calculate national performance statistics and benchmarks, as well as to set standards for measures included in NCQA's Accreditation program. Given plan permission, commercial data are also included in Quality Compass®. Health plans, purchasers, consultants and the media use Quality Compass data for comparative health plan performance analyses.

NCQA collects Medicare HEDIS data on behalf of the Centers for Medicare & Medicaid Services (CMS), and Medicaid HEDIS data on behalf of state agencies. In addition, NCQA collects commercial data on behalf of some states and the U.S. Office of Personnel Management for health plan report cards.
