When you head to the doctor or pharmacy for the first time this year don't be surprised when you have to pay for services from your Medicare plan. New year, new Medicare deductible. How much you pay and how frequently depends upon the type of plan that you have. If you moved from a Medicare supplement plan F to a Plan G remember that you will be paying the first $166 in doctor/provider bills before your plan begins to pay. Plan F - your plan pays the deductibles. Check your prescription drug plan too. Even if you kept the same plan the deductible may have changed.
