Graves, who works out four to five days a week and has a UnitedHealthcare Medigap policy, decided to seek coverage elsewhere after the company raised his policy's rates and eliminated SilverSneakers in California. He has signed up for a new policy with Blue Shield of California. Starting next year, UnitedHealthcare will offer members a package of fitness and wellness benefits instead of paying to use SilverSneakers — a move that will give the company more control over its benefits and may save it money. Seniors with UnitedHealthcare Medicare supplemental policies will get 50 percent off memberships at thousands of gyms across the country, telephone access to wellness coaches and access to various online communities and health-related resources.
