Welcome to the Medicare Health Outcomes Survey (HOS) Website
The Medicare HOS is the first patient-reported outcomes measure used in Medicare managed care. The goal of the Medicare HOS program is to gather valid and reliable clinically meaningful data that have many uses, such as targeting quality improvement activities and resources; monitoring health plan performance and rewarding top-performing health plans; helping people with Medicare make informed health care choices; and advancing the science of functional health outcomes measurement. Managed care plans with Medicare Advantage (MA) contracts must participate.
Each year a random sample of people with Medicare is drawn and surveyed from each participating Medicare Advantage Organization (MAO) that has a minimum of 500 enrollees (i.e., a survey is administered to a different baseline cohort, or group, each year). Two years later, the baseline respondents are surveyed again (i.e., follow up measurement). Cohort 1 was surveyed in 1998 and was resurveyed in 2000. Cohort 2 was surveyed in 1999 and was resurveyed in 2001, and so on. During the most recent HOS administration (2021 Round 24), Cohort 24 was surveyed and Cohort 22 was resurveyed using HOS 3.0. For data collection years 1998-2006, the MAO sample size was one thousand. Effective 2007, the MAO sample size was increased to twelve hundred. Since 2019, MAOs can request a survey sample larger than the standard sample of 1,200.

The memo states that the two HOS outcomes measures, Improving or Maintaining Physical Health and Improving or Maintaining Mental Health, will be moved to the display page on CMS.gov for the 2022 and 2023 Star Ratings. Due to the pervasive way in which the COVID-19 Public Health Emergency (PHE) has impacted and will continue to impact the validity of these two HOS outcomes measures for the 2020 and 2021 follow-up measurement periods, the 2022 and 2023 Star Ratings will be calculated without the use of Improving or Maintaining Physical Health and Improving or Maintaining Mental Health.
