UnitedHealthcare, it is a pretty big medical insurance company, just search it online you will see it. https://www.aarpmedicareplans.com/ How are AARP and UnitedHealthcare aligned in their mission? Over 20 years, the organizations have worked together to advance health care for older Americans, including continually enhancing Medicare plans, and creating better consumer experiences and robust research programs to improve health outcomes.

我也是AARP的member，怎么不知道它们有医疗保险呢？
