Gender differences in provider practice characteristics and medicare payment & services among diagnostic radiologists

Abstract

Background Gender-based differences in representation, practice settings, sub-specialty, billings, and payments among radiologists are poorly understood. Purpose To compare representation, scope of practice, productivity, and Medicare payments between female and male diagnostic radiologists. Methods and materials This cross-sectional (2017–2021) retrospective study examined the CMS Medicare Fee-for-Service Provider Utilization and Payment Database for payments to male and female diagnostic radiologists. The study practice setting, volume of services provided, number of unique beneficiaries served and financial data. Descriptive statistics were reported as mean with standard error (SE) for financial variables and median with interquartile range (IQR) for non-financial variables. Results Between 2017–2021 data, a total of 33,029 diagnostic radiologists provided services to Medicare fee-for-service beneficiaries, of whom 8,217 (24.9%) were female. Female radiologists were disproportionately in academic versus non-academic radiology (34.2% vs 22.6%); practicing in urban versus rural areas (26.3% vs 17.0%); in larger practices (30.1% in practices with ≥100 radiologists vs 17.5% in practices with 1–9 radiologists); and in certain subspecialties (breast imaging- 64.9%). On average, female radiologists received 86% of the total Medicare payments received by male radiologists (mean [SE], $301,931 [$1810] vs $352,604 [$1,164]; p
