Trends in Diagnostic Imaging Medicare Reimbursements: 2007 to 2019

Purpose: The aim of this study was to evaluate recent trends in Medicare reimbursement rates for various imaging studies. Methods: Common diagnostic radiologic studies were selected across multiple imaging modalities: bone densitometry, CT, CT angiography, mammography, MR angiography, MRI, nuclear medicine, radiography, and ultrasound. The Physician Fee Schedule Look-Up Tool from CMS was queried for Current Procedural Terminology codes to extract reimbursement data. All monetary data were adjusted for inflation to 2019 US dollars. The compound annual growth rate, average annual change, and total percentage change in reimbursement were calculated on the basis of these adjusted trends. Results: Inflation-adjusted Medicare reimbursement for all imaging modalities decreased between 2007 and 2019. The greatest mean decrease in reimbursement rates was observed for MRI (-$52.08), and the largest decrease in total percentage change was seen for bone densitometry (-70.5%). Nuclear medicine demonstrated the smallest mean decreases in both annual change (-$0.32) and total percentage change (-4.28%). Conclusions: This study examined Medicare reimbursements for radiologic studies from 2007 to 2019. After accounting for inflation, reimbursement rates were shown to decline for all studies across all imaging modalities except for individual studies in nuclear medicine, radiography, and ultrasound. Further investigation is encouraged to properly model future trends in reimbursement rates.
