About the Survey

The Consumer Assessment of Healthcare Providers and Systems (CAHPS) Survey for Accountable Care Organizations (ACOs) lets accountable care organizations participating in the Medicare Shared Savings Program and Next Generation ACO Model meet their requirement to measure patient experience of care.

The yearly CAHPS for ACOs Survey collects data through survey mailings and follow-up phone calls to non-respondents to measure the ten required patient experience-of-care summary survey measures included in the Next Generation ACO Model. CAHPS ask patients about the interpersonal aspects of health care—aspects for which patients may be the best, if not the only source of information, and areas that patients have identified as being important to them.

Next Generation ACOs are groups of doctors, hospitals, and other health care providers, who come together voluntarily to give coordinated high quality care to their Medicare patients.

For Next Generation ACOs

  • Have questions about your Next Generation ACO’s responsibility for survey administration? Visit our Next Generation ACO Model page.
  • All Next Generation ACOs must select a CMS-approved CAHPS for ACOs Survey vendor. Next Generation ACOs must complete the 2021 CAHPS for ACOs Survey vendor authorization process, which will open in Summer 2021. Each Next Generation ACO participating in the CAHPS for ACOs Survey will receive information about how to access the electronic vendor authorization in Summer 2021. Next Generation ACOs must select a vendor from the final list of 2021 CMS approved survey vendors.

The CAHPS for ACOs Survey allows Next Generation ACOs to meet their requirement to measure patient experience of care:

  • Next Generation ACO Model. CMS launched this new ACO model in 2016, partnering with Next Generation ACOs that are experienced in coordinating care for populations of patients and whose provider groups are ready to assume higher levels of financial risk and reward. The Model will consist of three initial performance years and two optional one-year extensions.
  • The CAHPS Survey for ACOs captures the core CG-CAHPS Survey plus the Summary Survey Measures that are part of the Next Generation ACO quality standard.
