Zytiga cost through Medicare?

Those with more knowledge will be around later so let someone without knowledge babble first. I turn 65 in January and went to a local guy that all my friends use for medicare planning. He determined that staying on my wife's medical plan was the best. He ran numbers on the website and my out of pocket cost for zytiga would have been $500 per month. Maybe that is just an Ohio medicare thing. Janssen has a help fund to cover costs and your Dr may have some local sources. Hopefully we'll see a generic soon and start paying a lot less.

I've already failed out on Zytiga for liver damage, so had to look it up on my policy. It falls in tier 5 for mine

In deductible phase, about $11000, but deductible is less than that for me, so I'm not sure what it would figure.
After deductible, about $3000
Donut hole, about $5000
After donut hole, about $600
