Outpatient Imaging Efficiency Core Measures by State

$179 / year

This dataset includes the State data for the Outpatient Imaging Efficiency Core Measures. These Core Measures gives information about the hospitals’ use of medical imaging tests for outpatients. Examples of medical imaging tests include CT Scans, MRIs, and mammograms.


Centers for Medicare & Medicaid Services (CMS) has adopted six Core Measures which capture the quality of outpatient care in the area of imaging. CMS notes that the purpose of these Core Measures is to promote high-quality efficient care. Each of the measures currently utilizes both the Hospital Outpatient Prospective Payment System (OPPS) claims and Physician Part B claims in the calculations. These calculations are based on the administrative claims of the Medicare fee-for-service population. Hospitals do not submit additional data for these measures. The measures on the use of medical imaging show how often a hospital provides specific imaging tests for Medicare beneficiaries under circumstances where they may not be medically appropriate. Lower percentages suggest the more efficient use of medical imaging. The purpose of reporting these measures is to reduce unnecessary exposure to contrast materials and/or radiation, to ensure adherence to evidence-based medicine and practice guidelines, and to prevent wasteful use of Medicare resources. The measures only apply to Medicare patients treated in hospital outpatient departments.
