Beta, have you called and asked for the speciality pharma department? Those of us with chronic diseases that need high dollar meds are frequently put into a special pharma program where you even get a single person point of contact. I get 3 mos of my MS injection via mail order for the same copay as the others but get handled through a different unit.
Is the total cost to you less even if you get only one mos at a time thrugh mail order? Usually, it is.
Another idea is to call the drug manufacturer itself. They frequently will have a website and a program specific to the disease and can help you find your way through the insurance programs.
Just some ideas.
