Public ReportingPosted August 6, 2025

Outpatient and Ambulatory Surgery CAHPS (OAS CAHPS) Survey results based on responses from patients who received an outpatient surgery or procedure between October 2023 and September 2024 are now publicly 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/).

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.

OAS CAHPS Preview Reports Available for Quarter 4, 2023 through Quarter 3, 2024
Public ReportingPosted July 17, 2025

The purpose of this announcement is to alert hospital outpatient departments (HOPDs) and ambulatory surgery centers (ASCs) that Preview Reports reflecting results from the Outpatient and Ambulatory Surgery CAHPS (OAS CAHPS) Survey for October 2023 through September 2024 (Q4, 2023 – Q3, 2024) are now available on the OAS CAHPS website.

The following are some frequently asked questions and answers about the Preview Reports. More information about the OAS CAHPS Survey Preview Reports can be found in the "Understanding the Preview Reports" link under the For Facilities menu tab on the OAS CAHPS website.

Who has access to a facility’s Preview Report?
HOPDs and ASCs participating in the OAS CAHPS Survey have access to their own reports. The Preview Report is not available to OAS CAHPS Survey vendors or to anyone other than the facility staff registered through the https://oascahps.org website. If facility staff want to share the Preview Report with their OAS CAHPS Survey vendor or with anyone else, they can export the results to a Microsoft Excel File and distribute it.

How does a facility user access its Preview Report?
The Preview Reports are posted on the secured (private) link on https://oascahps.org/. To access a facility's report, an authorized user must first log into the OAS CAHPS website with their registered username and password. Then, select the "Survey Preview Report" link under the "For Facilities" menu tab. All of the user's registered CMS Certification Numbers (CCNs) are displayed on the Preview Report webpage for review.

What results are shown in the Preview Reports?
For each CCN, the Preview Report shows the results for each variable and measure shown below:
1. The number of patients who were sampled; the number of completed surveys; and the response rate percentage during the reporting period;
2. The percentage of patients who rated the overall care they received at the HOPD or ASC a "9" or "10" on a scale of 0 (worst care possible) to 10 (best care possible);
3. The percentage of patients who reported YES, they would definitely recommend the HOPD or ASC to friends and family;
4. The percentage of patients who reported that the HOPD or ASC staff gave care in a professional way and the facility was clean;
5. The percentage of patients who reported that the HOPD or ASC staff definitely communicated with them about what to expect during and after the procedure; and
6. The percentage of patients who reported that the HOPD or ASC staff definitely gave them information about what to do if they had pain, nausea or vomiting, bleeding, or possible signs of infection as a result of the procedure or the anesthesia, if any of these outcomes were experienced. NOTE: While CMS reviews the data, Composite 3 will not be publicly reported on CMS’ website. At this time, this composite score is only available directly to each facility through the Preview Report.
More information about the OAS CAHPS Survey measures in the Preview Reports can be found in Chapter XVI of the OAS CAHPS Survey Protocols and Guidelines Manual available under the Survey Materials menu tab on the OAS CAHPS website.

Which sample months are included in the Preview Report results?
The results included in the current Preview Report are based on OAS CAHPS Survey response data from patients who had an outpatient surgery or procedure October 2023 through September 2024. The future anticipated public reporting periods are provided in Table 16.2 of the OAS CAHPS Survey Protocols and Guidelines Manual.

My facility participated in the OAS CAHPS Survey, but there are no results shown. Why?
OAS CAHPS Survey results are publicly reported when an HOPD or ASC has 4 quarters of OAS CAHPS Survey data. An HOPD or ASC must have had survey response data (patients who responded to the survey) in all 4 quarters included in the public reporting period for results to be publicly reported.

Notice of Publication of the Proposed Rule for Calendar Year 2026
Final/Proposed RulesPosted July 17, 2025

Process to Suppress OAS CAHPS Survey Data from Public Reporting for October 2025 Refresh
Public ReportingPosted July 15, 2025

During voluntary implementation, CMS allows participating ambulatory surgery centers (ASCs) to have their data suppressed, that is, not displayed on data.CMS.gov/provider-data.

The next refresh of OAS CAHPS Survey data (scheduled for October 2025) includes data from Quarter 1, 2024 – Quarter 4, 2024.

NOTE: The October 2025 refresh includes data for a full year that participation was linked to reimbursement (not voluntary) for HOPDs (Quarter 1, 2024 – Quarter 4, 2024). HOPDs can no longer choose to have their data suppressed, that is, not displayed on data.CMS.gov/provider-data, as there is no longer data linked to voluntary implementation for HOPDs.

For the October 2025 refresh, vendors must notify the OAS CAHPS Survey Coordination Team (via email at oascahps@rti.org) by August 15, 2025, of any ambulatory surgery center (ASC) 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 oascahps.org.

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: ASCs will continue to have the ability to choose to suppress data as long as any voluntary data are being reported, which will go through the July 2026 refresh. Starting with the October 2026 refresh, which will include data from Quarter 1, 2025 – Quarter 4, 2025, ASCs will no longer be able to choose to have their data suppressed as that refresh will include data for the full year that participation was linked to reimbursement (not voluntary) for ASCs.

Please contact the OAS CAHPS Survey Coordination Team via e-mail at oascahps@rti.org or call toll-free (866) 590-7468, if you have any questions.

In anticipation of the Quarter 1, 2025 data submission deadline (July 9, 2025), CMS will begin notifying ASCs of the status of their OAS CAHPS data submissions to the OAS CAHPS Data Center.
