About the National Implementation and Public Reporting Program

The Centers for Medicare & Medicaid Services (CMS) implemented a voluntary national reporting program for the OAS CAHPS Survey in January 2016. Participation in the program is open to any interested Medicare-certified Hospital Outpatient Departments (HOPDs) and free-standing ambulatory surgery centers (ASCs). CMS provides guidelines for survey administration similar to those implemented on other CAHPS surveys through the OAS CAHPS Survey Protocols and Guidelines Manual (available in the Survey Materials menu tab). Additionally, CMS-approved survey vendors administer the survey on behalf of HOPDs and ASCs and submit the data to the OAS CAHPS Data Center (RTI International, an independent, non-profit contract research organization). RTI International analyzes the data. CMS started publicly reporting survey results from voluntary participation on in 2018.

HOPDs and ASCs can benefit from participating in the voluntary national reporting program in the following ways:

  • Participating HOPDs and ASCs will be part of a program that provides valuable information to consumers about the quality of care provided nationally by HOPDs and ASCs.
  • Participating HOPDs and ASCs can compare their patient responses against their state and the national average. Results and links to these datasets will be available for download on a CMS website such as
  • HOPDs and ASCs may add supplementary questions to the survey and can choose to replace their internal patient experience of care surveys with the OAS CAHPS survey.
  • Participation in the OAS CAHPS Survey may be used to meet state or other regulations that require a patient satisfaction survey to be conducted regularly. Check with your state or accreditation bodies on such regulations.

In the CY 2020 Final Rule (Final Rule), CMS plans to continue voluntary implementation of the OAS CAHPS Survey throughout 2020. The OPPS and ASC Rules are updated annually. The CY 2020 Rule reflects participation information for the 2020 data collection period (CY 2022 payment determination). Any updates on OAS CAHPS Survey participation will be posted on this website after each Rule is published in the Federal Register.
