  • Five-Year Results of a Merger Between Vascular Surgeons and Interventional Radiologists in a University Medical Center
    From the Eastern Vascular Society Five-year results of a merger between vascular surgeons and interventional radiologists in a university medical center Richard M. Green, MD, and David Waldman, MD, PhD, for the Center for Vascular Disease* Rochester, NY Objectives: We examined economic and practice trends after 5 years of a merger between vascular surgeons and interventional radiologists. Methods: In 1998 a merger between the Division of Vascular Surgery and the Section of Interventional Radiology at the University of Rochester established the Center for Vascular Disease (CVD). Business activity was administered from the offices of the vascular surgeons. Results: In 1998 the CVD included five vascular surgeons and three interventional radiologists, who generated a total income of $5,789,311 (34% from vascular surgeons, 24% from interventional radiologists, 42% from vascular laborato- ries). Vascular surgeon participation in endoluminal therapy was limited to repair of abdominal aortic aneurysms (AAAs). Income was derived from 1011 major vascular procedures, 10,510 catheter-based procedures in 3286 patients, and 1 inpatient and 3 outpatient vascular laboratory tests. In 2002 there were six vascular surgeons (five, full-time equivalent) and four interventional radiologists, and total income was $6,550,463 despite significant reductions in unit value reimbursement over the 5 years, a 4% reduction in the number of major vascular procedures, and a 13% reduction in income from vascular laboratories. In 2002 the number of endoluminal procedures increased to 16,026 in 7131 patients, and contributions to CVD income increased from 24% in 1998 to 31% in 2002. Three of the six vascular surgeons performed endoluminal procedures in 634 patients in 2002, compared with none in 1998.

There are no required pre‐requisites, however; it is strongly recommended that enrollees have hands on coding experience in one or more areas as well as at least one core coding credential (CCS, CCS‐P, CPC, COC, CIC, etc.) Prior to registering enrollees should have knowledge of anatomy and medical terminology. When is the course open for enrollment? Until recently we only opened enrollment once or twice per year. To better serve potential customers, we decided to remove the specific enrollment deadlines, however, we are still limiting the number of enrollees we will allow in the course at any given time. The number of seats available will vary depending upon how many enrollees complete the course early and how much support current students require during the studies. We want to be sure that everyone who enrolls has the best experience possible and that we can provide them the time and attention needed to be successful in the course.

  • About Interventional Radiology
    FACT SHEET Contact Maryann Verrillo, (703) 460-5572 Ellen Acconcia, (703) 460-5582 Nonsurgical Interventional Radiology Procedures Offer Less Risk, Less Pain and Less Recovery Time Compared to Open Surgery What Is Interventional Radiology? The landscape of medicine is constantly changing, and for the past 30 years, interventional radiologists have been responsible for much of the medical innovation and development of the minimally invasive procedures that are commonplace today. Interventional radiologists pioneered modern medicine with the invention of angioplasty and the catheter-delivered stent, which were first used to treat peripheral arterial disease. By using a catheter to open the blocked artery, the procedure allowed an 82-year-old woman, who refused amputation surgery, to keep her gangrene-ravaged left foot. To her surgeon’s disbelief, her pain ceased, she started walking, and three “irreversibly” gangrenous toes spontaneously sloughed. She left the hospital on her feet—both of them. Charles Dotter, M.D., the interventional radiologist that pioneered this technique, is known as the “Father of Interventional Radiology,” and was nominated for the Nobel Prize in medicine in 1978. Angioplasty and stenting revolutionized medicine and led the way for the more widely known applications of coronary artery angioplasty and stenting that revolutionized the practice of cardiology. Today many conditions that once required surgery can be treated nonsurgically by interventional radiologists. Through a small knick in the skin, they use tiny catheters and miniature instruments so small they can be run through a person’s network of arteries to treat at the site of illness internally, saving the patient from open invasive surgery.

    AMSER GUIDE TO APPLYING FOR INTERVENTIONAL RADIOLOGY RESIDENCY VERSION 1 – AUGUST 2016 DEVELOPED AND EDITED BY Kyle J. Cooper, M.D.; Minhaj S. Khaja, M.D., M.B.A.; Sravanthi Reddy, M.D., Kate Klein, M.D. WITH HELP AND INPUT FROM OTHER AMSER MEMBERS INTRODUCTION This document is intended to provide guidance for students considering applying to a residency in interventional radiology, known to many as IR/DR). It includes answers to the most common questions that advisors and program directors have been asked, as well as some “hard data” from the national websites. Some advice reflects personal opinion of the authors. WHY INTERVENTIONAL RADIOLOGY? Unfortunately, many medical students are not exposed to interventional radiology until their third or fourth year of medical school, if at all. This can make it difficult for students to decide if this is the specialty choice for them. The following is general information about the specialty and the sort of personalities that tend to enjoy it as a profession. Careers in Medicine® (CiM) Vascular and interventional radiologists use their expertise in interpreting X-rays, ultrasound, and cross-sectional imaging other medical modalities to guide small instruments such as catheters and wires through the blood vessels or other pathways to treat disease percutaneously. These procedures are typically much less invasive and much less costly than traditional surgery. These radiologists diagnose and treat diseases by various radiologic imaging modalities including fluoroscopy, digital radiography, computed tomography, sonography, and magnetic resonance imaging. Common interventional radiological procedures include: angioplasty; thrombolytic therapy for blood clots; chemoembolization--delivery of chemotherapy directly to the site of the tumor; infection and abscess drainage; uterine fibroid embolization; removal of a urinary tract or fallopian tube obstruction; needle biopsy; and radiofrequency ablation.

  • Can an Interventional Radiologist Survive in Today's Turf War?
    UNIVERSITYUNIVERSITY OF WISCONSIN–MADISON OF WISCONSIN–MADISON Can An Interventional Radiologist Survive In Today’s Turf War? John Swietlik, MD, Paul H Yi, MD, Nathan Kim, MD & Jie Nguyen, MD, MS Department of Diagnostic Radiology University of Wisconsin-Madison UNIVERSITY OF WISCONSIN–MADISON Disclosures The authors have no financial disclosures relevant to this electronic exhibit. University of Wisconsin–Madison 2 UNIVERSITY OF WISCONSIN–MADISON Introduction • Increasing numbers of imaging-assisted endovascular and cardiac procedures are being performed by non-Interventional Radiologists. “Between 1997 and 2002, procedure volume in percutaneous peripheral arterial interventions grew at faster rates among cardiologists, vascular surgeons, and other physicians than it did among radiologists.” • This trend has raised concerns amongst Interventional Radiology (IR) physicians regarding the financial viability of the field. University of Wisconsin–Madison 3 UNIVERSITY OF WISCONSIN–MADISON Let the Turf Wars Begin • As a result, there has been concern about turf wars between IR and other endovascular and cardiac procedure-oriented fields for decades. University of Wisconsin–Madison 4 UNIVERSITY OF WISCONSIN–MADISON Goals & Objectives • The purpose of this study was to assess the differences in maximum Medicare reimbursements to IR, VS, and Cardiology physicians. In other words… Can the field of IR remain financially viable in today's healthcare market? University of Wisconsin–Madison 5 UNIVERSITY OF WISCONSIN–MADISON Methods • The Medicare Provider Utilization and Payment Database is a publicly available database provided by the Centers for Medicare & Medicaid services (US Government organization) that discloses all Medicare payments by dollar amount to physicians from 2012 to the present. • This database was queried for all IR, VS, and Cardiology physicians who received Medicare reimbursements in 2014.
