HEDIS Requests

The Healthcare Effectiveness Data and Information Set, or HEDIS, is a tool used by more than 90% of America's health plans to measure performance on important dimensions of care and service, including the delivery of immunizations. CIIS can provide HEDIS matches for health plans provided that they have a signed Letter of Agreement and submit data to CIIS on at least a monthly basis.
