The Centers for Medicare & Medicaid Services (CMS) released a final rule with comment period that updates payment rates for hospital outpatient services paid under the Medicare outpatient prospective payment system (OPPS) and establishes relative payment weights and amounts for services furnished in ambulatory surgical centers (ASCs) for the calendar year 2012 (CY12) ASC payment system. These final changes will be applicable to services furnished on or after January 1, 2012. CMS also proposes to update the requirements for both the Hospital Outpatient Quality Reporting (OQR) Program, as well as the ASC Quality Reporting System, and make additional changes to the provisions of the Hospital Inpatient Value-Based Purchasing (VBP) Program. The final rule is effective January 1, 2012. Comments on the proposal are due January 3, 2012.
