GRID Exam-Level Data File Reference Documents

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 (Note: Version 2.0 will be discontinued on April 30, 2023. Version 2.1 will be the only accepted version after this date.):

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

    2.1 - Addition of Physician TIN.

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.


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