Medicare pays for surgical procedures performed at ambulatory surgical centers (ASC) and hospital outpatient departments through different payment systems. Although they perform a similar set of procedures, no comparison of ASC and hospital outpatient per-procedure costs has been conducted. The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 directed GAO to compare the relative costs of procedures furnished in ASCs to the relative costs of those procedures furnished in hospital outpatient departments, in particular, how accurately the payment groups used in the hospital outpatient prospective payment system (OPPS) reflect the relative costs of procedures performed in ASCs. To do this, GAO collected data from ASCs through a survey. GAO also obtained hospital outpatient data from the Centers for Medicare & Medicaid Services (CMS).
