What does OAS CAHPS Mean?

  • Outpatient and Ambulatory Surgery Survey
  • Consumer Assessment of Healthcare Providers and Systems

What’s the Purpose of the OAS CAHPS Survey?

  • Measure the experience of care in Hospital Outpatient Departments (HOPDs) and Ambulatory Surgery Centers (ASCs)
  • Encourages quality improvement
  • Allows consumers to make informed decisions when choosing an HOPD or ASC because the data is available publicly

Why Should Organizations Care Now?

  • There are TWO entities with mandates quickly approaching:
    • Hospital Outpatient Department surveys (HOPD) will be mandated in 2024
      • Must have 300 completed surveys per year*
        • If there are less than 60 patients a year, the Hospital can file for an exemption
    • Ambulatory Surgery Center (ASC) will be mandated in 2025
      • Must have 200 completed surveys per year*
        • *If there are less than 60 patients a year, the Surgery Center can file for an exemption

How Do Organizations Know if They Qualify?

  • If they perform procedures that are within range of CPT-4 Codes for Surgery
  • Are Medicare-certified
  • Have a CMS Certification Number (CCN)
  • Bill under the Payment System OR the Outpatient Payment Prospective System (OPPS)
  • Participate in the Ambulatory Surgical Center Quality Reporting (ASCQR) Program OR the Hospital Outpatient Quality Reporting Program (Hospital OQR)
  • Have an agreement with CMS

What Happens if Organizations Don’t Do Surveys?

  • HOPDs and ASCs that do not administer and report OAS CAHPS when it becomes mandatory could be subject to a penalty of 2% of their annual Medicare payment update.

Why Should Companies Consider Starting the Surveys Before the Mandate Starts?

  • If HOPDs and ASCs start early, they will get the chance to see where they’re doing well and where they can improve before the data goes “public”.
  • Bringing over 6,200 Medicare-certified ASCs in the United States into compliance with this survey will be a time-consuming process. Waiting until the last moment to start this is not recommended.
