Outpatient and Ambulatory Surgery CAHPS (OAS CAHPS) Survey results based on responses from patients who received an outpatient surgery or procedure between January 2024 and December 2024 are now publicly available on CMS websites. Data for both ASCs and HOPDs is available on the Provider Data Catalog (PDC) website (formerly known as Data.Medicare.gov). The PDC website provides downloadable datasets (direct link: https://data.cms.gov/provider-data/). Starting with this refresh, which includes four quarters of data linked to reimbursement for HOPDs, OAS CAHPS data for HOPDs are now also available on Care Compare (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.

For more information about how the data were analyzed and for the patient-mix adjustment factors that were used to statistically adjust the results that are currently being publicly reported, click on the "Patient Mix Adjustment Factors" in the Quick Links box on the Home page.
