Many vascular access centers (VACs) that currently operate as an extension of practice (EOP) are evaluating the viability and legal permissibility of a conversion to an ambulatory service center (ASC) and the related costs. VACs are outpatient facilities that specialize in access maintenance for patients with end-stage renal disease (ESRD). The valuation of a VAC in-office carve-out and the related conversion to an ASC is explained in an article, “Valuation Considerations for Vascular Access Centers in 2017,” by Brad Brumbaugh and Jason Ruchaber, both with VMG Health in the Denver office.
