GRID implemented 11 new radiology-specific quality measures in 2020. When implemented into routine clinical practice, these quality measures support the delivery of patient-centered, evidence-based quality care for the promotion of positive health outcomes. Seven of the 11 quality measures are approved by the Centers for Medicare and Medicaid Services (CMS) for use in the Merit-based Incentive Payment System (MIPS) when submitting your data to CMS through the NRDR Qualified Clinical Data Registry (QCDR).
