I use a medicare licensed representative. Doesnt cost you. I just send her my list of drugs and my wifes and she tells me the best one. Medicare A&B and my supplement never change. Those are pretty fixed in what they offer. But your drug provider has different guidelines. Currently using UHC but its $25 month but covers one cholesterol drug I need. But I am going to switch because I think Cigna will cover the drug at $12 month. Worth checking anyway. I think around the 15th November is open enrollment.
