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 four file versions available:

    1.0 - Original version

    1.1 - Includes a Facility ID data element, to allow multiple facilities to be submitted within a single file. 

    1.2 - Includes a Facility ID data element and two new data elements, "Multiple readers" and "Place of service."

    2.0 -  Includes patient demographics, clinical focus and whether follow-up imaging is recommended or performed.

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.


We encourage sites to convert to Version 1.2 at their earliest convenience, particularly if participating in QCDR, as the new fields may impact QCDR measures in future performance years. 

After completion of the 2019 QCDR/MIPS cycle (tentatively March 2020), Versions 1.0 and 1.1 of GRID will no longer be accepted for submission of exam-level data.

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