Data Submission Details
HEDIS is the nation’s most widely used set of health care performance measures. NCQA collects Medicare and Exchange data on behalf of the Centers for Medicare & Medicaid Services (CMS), collects Medicaid HEDIS data on behalf of state agencies and collects commercial data on behalf of states and the U.S. Office of Personnel Management.
HEDIS data help calculate national performance statistics and benchmarks and set standards for measures in NCQA Accreditation.
With 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.
If your health plan is interested in submitting HEDIS data for the first time, contact the NCQA Data Collection team at https://my.ncqa.org/. All health plans submitting HEDIS data must complete the Healthcare Organization Questionnaire (HOQ) to request a submission. Plans that submit the HOQ will have automatic access to the Interactive Data Submission System (IDSS) that NCQA uses to collect non-survey HEDIS data.
For information on how to get started, review our New Orgs Submitting document.
Organizations that identify errors in a reported measure rate or its component after data submission are required to report the error to NCQA if it exceeds a five percent threshold. For a summary of reported data errors, visit the data errata page here.
