A big worry for Memphis residents about having a Medicare plan is whether the monthly premium will ever increase. Current estimates through 2014 show that while Medicare premiums are in fact expected to increase, the total amount of the increase will be small. A study by the Center for Medicare and Medicaid Services projects Medicare premiums for Plan B to cost $108.20 in 2012, $112.10 in 2013 and $117.10 in 2014. Premiums could increase more if the Medicare recipient is in a high income bracket.
