Retirees will have a bit more money in their pocket in 2015 with the 1.7% increase announced for Social Security benefits. Coupled with no increase in the Medicare Part B premium, seniors are in a bit better shape than they have been in the past. One more financial step seniors should take this year is to review their Medicare plan for 2015, especially their Medicare Part D prescription drug plan. While premiums on these plans have held steady - the changes in deductibles and co-pays can lead to big out of pocket expenses in 2015. Medicare Open Enrollment ends Dec. 7 so shop and compare plans now.
