What is the Health Outcomes Survey (HOS)?

HOS is an annual survey administered in August to a random sample of Medicare Advantage patients. The same patients are surveyed again two years later to assess change in physical and mental health status.

The survey is a measurement of patients' perception of their physical and mental health and overall quality of life.

The survey results impact CMS star ratings.
