@peggyle If your drug plan is through a private company ( not a Medicare Part D or Medicare Advantage plan, or any government sponsored insurance) you are eligible to receive a coupon from the Eliquis manufacturer's website which allows you to purchase the drug for $10 for a month's supply or $30 for a 90 day supply. The requirements are that you need that private drug health plan, are a US citizen, or a citizen of Puerto Rico, and don't have your drug plan via a government sponsored entity.

I have Medicare Parts A and B and a secondary insurance through the federal employees' Blue Cross/Blue Shield plan, our drug plan is included in the secondary insurance. It's a private, non-government company so I qualify for this discount.

Good question as to why you would have to pay more than $110/month. We went through the medicare.gov site, so perhaps that is a factor, or not. I asked AI why there would be such a gap in cost per month, and two answers came up that might help: one is that location is a huge factor. If we live in a more rural area, and get meds locally, it stated there is a higher cost. The second factor was the chosen pharmacy. We live in a large city, and we chose the mail order option. That gave us Optum Rx as the mail order pharmacy.
I tried going through Medicare.gov just a few minutes ago and got the same pricing structure, if that helps.
It does give me more of a peace of mind going through a pharmacy here in the States. My Husband also gets Multaq, and the high cost of that makes the $110/month more worth it. I never received our last order from the Canadian pharmacy, and was out nearly $1000. They said it was delivered, the post office said it had no record. Kind of hard to fight internationally. So the decision was easier.
I hope this helps.
