GRID 2.0 Measures

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). 

GRID 2.0 Measures

Bolded measures indicate that the measure is also available for MIPS reporting through the QCDR.

  • Recommended Follow-up for Imaging Findings

  • Appropriateness: Follow-up CT Imaging for Incidentally-Detected Pulmonary Nodules According to Recommended Guidelines

  • Follow-up Recommendations for Incidental Findings of Simple-Appearing Cystic Renal Masses

  • Appropriate Follow-up Imaging for Benign Adrenal Masses

  • Interpretation of CT Pulmonary Angiography (CTPA) for Pulmonary Embolism (PE)

  • Incidental Coronary Artery Calcification Reported on Chest CT

  • Use of Structured Reporting in Prostate MRI

  • Surveillance Imaging for Liver Nodules <10 mm in Patients at Risk for Hepatocellular Carcinoma (HCC)

  • Use of Quantitative Criteria for Oncologic FDG PET Imaging

  • Use of Low Dose Cranial CT or MRI Examinations for Patients with Ventricular Shunts

  • Use of Low Dose CT Studies for Adults with Suspicion of Urolithiasis or Nephrolithiasis

More information on the measure descriptions and the data elements can be found in the attachment below. Please review this document to determine which measures are relevant to your practice, and what elements will be needed to calculate performance for each measure.

How to Upload

To upload data to GRID for these measures, please refer to the GRID Exam Data Upload File Specification and Data Element document and the GRID Exam Data Form Template 2.0. The file specification describes the necessary data elements required for exam-level data records, which you would then implement within the upload template. Once the upload template is filled out, please navigate to the GRID registry within the NRDR to upload your file. More information on file upload can be found in the GRID Data Submission Overview article.

Please contact the NRDR Support Desk at if you need assistance with these measures.

Simplified Submission for MIPS Participants

For MIPS participants, a simplified submission option is available using a template file similar to MIPS measure submission rather than uploading data via GRID. Each GRID 2.0 measure includes a list of denominator codes and numerator performance codes which would be populated into an Excel or Text template and uploaded to the MIPS Participation Portal using the "Upload Data" tab. GRID registration is not required for users opting to submit using this method. These measures will appear under the MIPS Performance Report as "QACRad" rather than "ACRad" to differentiate them from those submitted via standard GRID upload. Users can choose either method for reporting these measures. Please see the attached specifications and template file for more details.
