While advances in medical technology and changes in Medicare payment policy over the past four decades have expanded the list of procedures for which the Centers for Medicare & Medicaid Services (CMS) will reimburse ASCs, Medicare policies have not kept pace with innovation. There are more than 300 procedures that are reimbursed in hospital outpatient departments (HOPD) but not ASCs. Other procedures, such as total hip, shoulder, wrist and ankle, that ASCs are performing safely on non-Medicare patients are still on the inpatient-only (IPO) list. ASCA is asking CMS to add codes to the ASC-payable list that our clinicians know can be performed safely on the Medicare population in the ASC setting.
