Outpatient and Ambulatory Surgery CAHPS (OAS CAHPS) Survey results based on responses from patients who received an outpatient surgery or procedure between January 2025, and December 2025 are now publicly available on CMS websites. Downloadable datasets for both ASCs and HOPDs are available on the Provider Data Catalog (PDC) website (direct link: https://data.cms.gov/provider-data/). OAS CAHPS data for HOPDs is also available on the Care Compare website (direct link: https://www.medicare.gov/care-compare/).

You can access OAS CAHPS Survey results at the facility, state and national levels. As a reminder, OAS CAHPS Survey results are updated quarterly, as shown in Table 16.2 of the OAS CAHPS Survey Protocols and Guidelines Manual.
