During voluntary implementation, CMS will allow participating hospital outpatient departments (HOPDs) and ambulatory surgery centers (ASCs) to have their data suppressed, that is, not displayed on

OAS CAHPS Survey data are scheduled refresh in October 2024, which includes data from Quarter 1, 2023 - Quarter 4, 2023.

For the October 2024 refresh, vendors must notify the OAS CAHPS Survey Coordination Team (via email at by May 15, 2024, of any CCNs that choose to exclude their data from public reporting. Please note that the deadline for suppression is earlier than the date by which the Preview Reports are posted on

The e-mail message to the Coordination Team for suppression requests should include the HOPD's or ASC's name and CMS Certification Number (CCN).

Future plans for Public Reporting: Participation requirements and public reporting for OAS CAHPS will change for HOPDs for data collected for CY 2024 and for ASCs for data collected for CY 2025.

  • As noted in the Final Rule for CY 2024, to receive the annual payment update (APU) for calendar year (CY) 2026, all Medicare-certified hospital outpatient departments (HOPDs) that are not eligible for an exemption from participation in the OAS CAHPS Survey must participate in the OAS CAHPS Survey on a continuous monthly basis from January 1, 2024, through December 31, 2024. ASCs will follow a similar schedule in 2025.
  • Because participation is no longer voluntary for HOPDs, HOPDs can no longer choose to have their data suppressed from public reporting on once the data from 4 quarters of 2024 are publicly reported.
