Health Insurance Company Quality Rating System

Covered California health plans are rated using clinical measure data and members’ reported experiences with their plans. The system has one to five stars, with five stars being the top rating.

To assign the star rating, each health plan is compared to 300 other health plans across the nation. A five-star plan means the health plan scored among the top plans nationwide; a three-star rating is assigned to plans that scored in the middle; those plans that scored somewhat lower than the average were rated two stars and plans that scored somewhat higher than average were rated four stars; a one-star rating means the plan's socre was among the lowest.

Health plan quality ratings are calculated by Covered California using data the plans provided to the federal government in 2016. The use of star ratings is being tested to help improve the ways this information is communicated to consumers.
