In about two years, full prescription coverage under Medicare will begin. In return for a monthly premium of about $35, most seniors without any prescription drug coverage can now expect to see their current drug bills cut roughly in half. This new law will provide 95 percent coverage for out-of-pocket drug spending that exceeds $3,600 a year. For the first time, we're giving seniors peace of mind that they will not have to face unlimited expenses for their medicine.
