You may have heard that Medicare will be costing you a lot more in 2016, with premiums increasing perhaps over 50%. Rest assured that is not the case. In fact, it’s quite likely you will pay the same as you did in 2015. Since Social Security benefits are staying flat next year, due to a zero cost-of-living-adjustment (COLA), by law the same will be true with Medicare Part B premiums for most participants. That is because of a provision governing premiums that provides they cannot rise more than the amount a person’s Social Security benefits increase due to inflation – if total income is within limits.
