The GRID Exam Data Upload File Specification and Data Element document, posted below, describes the file specification and each data element for exam-level data records used for capturing data for QCDR non-MIPS measures. 

There are currently two file versions available, versions 1.0 and 1.1. Version 1.1 includes a Facility ID data element, to allow multiple facilities to be submitted within a single file.

Note: The Facility ID is optional; in the event the field is left blank, data will be uploaded to the current facility selected in the facility picker, in the upper right corner of the portal.


In early July, 2019, we will release Version 1.2 of the GRID file specifications. Version 1.2 includes two new data elements, Multiple Readers and Place of Service. After completion of the 2019 QCDR/MIPS cycle (tentatively March 2020), Versions 1.0 and 1.1 of GRID will no longer be accepted.

Consult GRID Data File Uploads for detailed instructions for creating a file of exam-level data for upload to the GRID.
