Those certainly are substantial increases but are they Obamacare-related increases? I am still in my 50s (barely), so haven't looked closely at Medicare yet.
I received a letter from my husband’s insurer that said I was being removed because of obamaCare and I had to go on medicare (forced),
After the first year, these premiums went up and I was told because of obamaCare. Plan D is the drug program, not only did the premiums go up what they would cover was reduced. IE thyroid meds went from $3.00 to no coverage, because they were not considered medically necessary.
So YES, these increases are because of obamaCare.
My husband’s went up and the letter from the insurer said directly because of obamaCare, premiums up - coverage down.
