This study states that In the current era of cost containment, the financial impact of high-cost procedures such as endovascular aneurysm repair (EVAR) remains an area of intensive interest. Previous reports suggested slim to negative operating margins with EVAR, prompting widespread initiatives to reduce cost and to improve reimbursement. In 2015, the Centers for Medicare and Medicaid Services (CMS) announced the reclassification of EVAR to more specific diagnosis-related group (DRG) coding and predicted an overall increase in hospital reimbursement. The potential impact of this change has not been described.
Patients undergoing elective EVAR at a single institution between January 2014 and December 2018 were identified retrospectively, then stratified by date. Group 1 patients underwent EVAR before DRG change in 2015 and were classified with DRG 237/238, major cardiovascular procedure. Group 2 patients underwent EVAR after the change and were classified as DRG 268/269, aortic/heart assist procedures. The total direct cost included implant cost, operating room (OR) labor, room and board, and other supply costs. Net revenue reflected real payer mix values without extrapolation based on standard Medicare rates. Hospital profit was defined as the contribution to indirect (CTI), subtracting total direct cost from net revenue.
