Having been a member of AARP since turning 55, am now 72, I have consistently noticed a greater and greater relationship with United Health Care Insurance. The amount of money this company gives to AARP is certainly a large factor in that relationship. However, the founding principle of AARP is to serve it older membership in ways that benefit them not just AARP. What many seniors are not aware of is that Medicare supplements have to offer the same basic benefits. For example, plan E does not require copays, or in network providers. The only difference between various insurance companies for this policy is price. United HealthCare is among the most expensive. What AARP should be doing is letting its members know that they should check with an independent insurance agent to see what the best price vs benefits they can get for their supplemental.
