How Much Will Medicare Rise? 
Every year Congress decides how much of tax revenues to allocate for Medicare spending . They also set the deductibles for the coming year as well as premiums for Part A and Part B . This is all done under a full moon at midnight following the swinging of a dead chicken over their head ceremony . Seriously , there is no predicting what Congress will do since it is based on political whim and has nothing to do with inflation , costs or anything else . Over the last few years deductibles and premiums have risen 4 - 6 % which is an effective cost to you of 8 - 12 % .
