katiekateny,

I found myself in your situation in March when I was diagnosed with persistent Afib. My Eliquis costs me $106 a month and I know several people with Medicare Part D who only pay $47 a month and my pharmacist told me $45 to $47 is what most on Part D pay. So, now that it is open enrollment, I am looking for a plan that pays better. I would recommend you do the same.
We have a senior center here with very experienced people who know the best plans based on your medications. Perhaps you can find help to find the best plan. I know it hits hard to see the cost of eliquis, but stroke is a serious risk. Good luck with finding that better plan.
