Yes, and those premiums will probably increase for 2016 since they didn't for 2015.

Flowergirl, are you saying that Medicare premiums are set to increase up to 51%, or are you talking about private supplemental insurance?

The oft related cuts to Medicare were actually to the Medicare Advantage program subsidies. Here is the scoop about it. The long and short of it is that the Medicare Advantge program was instituted in the George W Bush administration to increase competition in the Medicare field by involving private insurers. It has been a popular program (I am in a Medicare Advantage plan). BUT the payouts to Medicare Advantage per insuree averaged higher than Medicare itself and the cuts were to level the difference. Each year with the Advantage plan you can go shopping for any of the Advantage plans that are active in your state. So far I have been satisfied with the Advantage plans and their coverage and prices. Like others shopping for medical insurance you typically have a choice of prices in each of the plans depending on deductivles, etc. 

Here is the article explaining the cuts and how it has been used politically.
