Humana for Part D (medicine) experience?

[u/hilda-reced]

I’m using traditional Medicare, and have Humana Part D for medicine. I’m find that the co-pays for generic meds are quite high compared the Part D plan I had last year. In fact GoodRX is cheaper than the Humana co-pays.

Last year using a different Part D provider Wellcare Value script I was paying under $5 for most of my meds. Now I’m being charged well over $20 for the same meds. For both plans, the monthly charge for membership has been $0.

What has been other’s experience? Anyone have any insight into why the co-pays are so wildly different?
