This is my first year on Medicare and I signed up with Humana because it is the plan offered through my state retirement. As soon as I can, I will be changing to a Medicare advantage plan with another company. I am diabetic and Humana keeps denying the medications my doctor prescribes. These are not new and expensive drugs, they have been around for years (glyburide, 70/30 insulin). So far, I've found more drugs they won't approve than they will. During my career, I had insurance with some stellar companies and some not so good. Humana is among the worst.
