Trends in the Use of Percutaneous Versus Open Surgical Breast Biopsy: An Update.

Despite the emergence of core-needle (percutaneous) biopsy as the standard of breast care, open surgical breast biopsies continue to be performed with variable frequency. The aim of this study was to compare trends in the use of percutaneous and open surgical breast biopsies and the relative roles of radiologists and surgeons in performing them. The nationwide Medicare Part B Physician/Supplier Procedure Summary Master Files for 2004 to 2016 were reviewed, and trends were studied in the total volume of breast biopsies performed in the Medicare fee-for-service population and in volumes of imaging-guided percutaneous biopsies (IGPBs) and open surgical biopsies. Using Medicare's physician specialty codes, the numbers of procedures performed by different specialties were determined. Trends in the type of imaging used for IGPBs were analyzed using the relevant Current Procedural Terminology codes, introduced in 2014. Between 2004 and 2016, utilization of IGPBs increased from 124,423 to 187,914 (+51%), whereas the use of open surgical breast biopsies declined from to 6,605 to 2,373 (-64%). IGPBs performed by radiologists increased from 89,493 to 160,485 (+79%), and IGPBs by surgeons declined from 30,264 to 24,703 (-18%). Among IGPBs from 2014 to 2016, ultrasound-guided and MRI-guided percutaneous biopsies increased, whereas stereotactic biopsies declined. There is a steady upward trend in the utilization of imaging-guided breast biopsies, and a majority are performed by radiologists. Ultrasound is the primary guidance technique used in percutaneous breast biopsies.
