Value Based Purchasing Program for Ambulatory Surgical Centers

The Affordable Care Act requires the Secretary of Health and Human Services to develop a plan to implement a value-based purchasing (VBP) program for payments under the Medicare program for ambulatory surgical centers (ASCs). The Secretary submits a report to Congress containing this plan.

The Report to Congress (PDF) describes the current efforts to improve quality and payment efficiency in ASCs.  In addition, it considers the steps required in designing and implementing an ASC VBP program for payments under the Medicare program.  CMS views VBP as an important step forward in revamping how Medicare pays for health care services; moving the program towards rewarding better value, outcomes, and innovations, instead of merely volume.

The ASC VBP Report to Congress was authorized under Section 3006(f) of the Patient Protection and Affordable Care Act (Pub. L. 111-148), enacted on March 23, 2010, as amended by the Health Care and Education Reconciliation Act of 2010 (Pub. L. 111-152), enacted on March 30, 2010 (collectively known as the Affordable Care Act) (as added by section 10301(a) of the Affordable Care Act).
