The purpose of this study was to assess potential disparities in the utilization of advanced imaging during emergency department (ED) visits. This retrospective study was conducting using 5% Research Identifiable Files. All CT and MRI (together defined as “advanced imaging”) examinations associated with ED visits in 2015 were identified for continuously enrolled Medicare beneficiaries. Among Medicare beneficiaries receiving care in U.S. EDs, significant disparities exist in advanced imaging utilization. Although imaging appropriateness was not investigated, these findings suggest inequity. Further research is necessary to understand why consistent health benefits do not translate into consistent imaging access among risk-adjusted ED patients. Full Article

The purpose of this study is to assess recent trends and characteristics in radiologist-practice separation across the United States. Using the Medicare Physician Compare and Medicare Physician and Other Supplier Public Use File data sets, the researchers linked all radiologists to associated group practices annually between 2014 and 2018 and assessed radiologist-practice separation over a variety of physician and group characteristics. Multivariate logistic regression modeling was used to estimate the likelihood of radiologist-practice separation. Full Article

Using the Medicare Physician-Supplier Procedure Summary Master File, we evaluated the evolving use of fMRI in
Medicare fee-for-service beneficiaries from 2007 through 2017. Annual use rates (per 1,000,000 enrollees) increased from 17.7 to
32.8 through 2014 and have remained static since. Radiologists have remained the dominant specialty group from 2007 to 2017
(86.4% and 88.6% of all services, respectively), and the outpatient setting has remained the dominant place of service (65.4% and
65.4%, respectively). Full Article

This study characterize national trends in oncologic imaging (OI) utilization. This retrospective cross-sectional study used 2004 and 2016 CMS 5% Carrier Claims Research Identifiable Files. Radiologist-performed, primary noninvasive diagnostic imaging examinations were identified from billed Current Procedural Terminology codes; CT, MRI, and PET/CT examinations were categorized as “advanced” imaging. OI examinations were identified from imaging claims’ primary International Classification of Diseases-9 and International Classification of Diseases-10 codes. Imaging services were stratified by academic practice status and place of service. State-level correlations of oncologic advanced imaging utilization (examinations per 1,000 beneficiaries) with cancer prevalence and radiologist supply were assessed by Spearman correlation coefficient.OI usage varied between practice settings. Although the percentage of advanced OI done in academic settings nearly
doubled from 2004 to 2016, the majority remained in nonacademic practices. Full Article

The operational and financial impact of the widespread coronavirus disease 2019 (COVID-19) curtailment of imaging services on radiology practices is unknown. We aimed to characterize recent COVID-19-related community practice noninvasive diagnostic imaging professional work declines. The authors used imaging metadata from nine community radiology practices across the United States between January 2019 and May 2020, and mapped work relative value unit (wRVU)-weighted stand-alone noninvasive diagnostic imaging service codes to both modality and body region.

The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on imaging utilization across practice settings. The purpose of this study was to quantify the change in the composition of inpatient imaging volumes for modality types and Current Procedural Terminology–coded groups during the COVID-19 pandemic.

Bundled payments have been touted as mechanisms to optimize quality and costs. A recent feasibility study evaluating
bundled payments for screening mammography episodes predated widespread adoption of digital breast tomosynthesis (DBT). We
explore a similar model reflecting emerging acceptance of DBT in breast cancer screening.
Methods: Using 4-year data for 59,094 screening episodes from two large facilities within a large academic health system, we utilized published methodology to calibrate Medicare national allowable reference prices for women undergoing screening mammography before and after practice-wide implementation of DBT.
