Evaluate utilization trends in percutaneous extremity venography among radiologist and nonradiologist providers. The nationwide Medicare Part B fee-for-service databases for 2010to 2018 were used to obtain percutaneous extremity venography volumes. Two procedure codes were used to identify extremity venography procedures, including both unilateral and bilateral procedures. Procedure volumes were aggregated based on physician specialty, specifically as radiologists, cardiologists, vascular surgeons, general surgeons, or other providers. Procedures were stratified based on place of service, including inpatient, hospital outpatient departments, office, emergency room, and other. The additional codes for transcatheter and percutaneous mechanical thrombectomy were not included to avoid potentially duplicating procedures. From 2010 to 2018, the total number of percutaneous extremity venography procedures declined (-39%) but began to plateau in 2017 to 2018 (-10%) (Table). More procedures were performed in the hospital outpatient department or office setting (N = 263,991; 58% of total volume) compared to inpatient (N = 183,386; 40%). Radiologists performed the majority of these procedures (N = 164,580; 36% of the total volume), followed by cardiologists (N = 138,949; 31%) and vascular surgeons (N = 75,431; 17%). However, radiologists saw the greatest decline in procedure volumes (25,907 to 13,108; -49%), compared with cardiologists (20,514 to 12,629; -35%) and vascular surgeons (9684 to 7921; -18%). The volume of percutaneous extremity venography procedures performed in the Medicare population declined from 2010 to 2018, most likely related to more stringent patient selection. Radiologists performed the majority of procedures but were closely followed by cardiologists.Tabled 1Total Number of Submitted Services per Year for Percutaneous Extremity Venography201068,426201160,395201252,906201350,002201448,057201545,926201644,417201742,001201841,598Total453,728 Open table in a new tab
