Regence Medical Insurance

Well, I just found out that my Regence Evolve Plus medical insurance, which I started out paying $150 per month for and has now gone up to a whopping $336 per month, now "covers" Rebif.  What this means is that I am now "allowed" to get my Rebif with 50% coverage.  50% of $2400????  And that helps me how??  MS Lifelines, which is a great organization, was helping me get my Rebif for a reasonable amount, considering my less-than-stellar income.  Now, MS Lifelines has a program to help, but because of the so-called insurance coverage, the program is not as helpful as when I have no coverage.  I still have several months to go before I am eligible for Medicare, and I have no idea what that means.
