Contact Information for Medicare Advantage Organizations (MAOs)

CMS developed the Medicare Health Outcomes Survey (HOS) Vendor Program to establish standardized data collection to promote comparability of results across Medicare Advantage Organizations (MAO). MAOs select and contract with a CMS-approved HOS survey vendor to administer the survey using a mixed mode (mail and telephone) protocol. To become a CMS-approved HOS survey vendor, an organization must demonstrate that it has the capability, experience, and personnel to collect and report accurate HOS survey results and successfully complete the annual HOS survey vendor training. The organizations listed below, in alphabetical order, have met the requirements to administer the 2023 Medicare Health Outcomes Survey (HOS).
