CMS rates qualified health plans (QHPs) offered through the Marketplaces using the Quality Rating System (QRS), which is based on third-party validated clinical measure data and QHP Enrollee Survey response data. CMS calculates QRS ratings annually using a 5-star scale. QHP issuers contract with HHS-approved survey vendors that independently conduct the QHP Enrollee Survey each year. QRS ratings and QHP Enrollee Survey results may change from one year to the next. For more information, please see CMS' Health Insurance Marketplace Quality Initiatives website at: http://www.cms.gov/Medicare/Quality-Initiatives-Patient-Assessment-Instruments/QualityInitiativesGenInfo/Health-Insurance-Marketplace-Quality-Initiatives.html.
 Plan quality ratings and enrollee survey results are calculated by CMS using data provided by health plans in 2019. The ratings are being displayed for health plans for the 2020 plan year. Learn more about these ratings. https://www.healthcare.gov/quality-ratings/.
