No. Even if your Medicare prescription drug plan offers coverage for some generics in the Coverage Gap (for example, you pay a $5 co-pay for all Tier 1 generics), your Medicare Part D plan is not required to offer the same Coverage Gap cost-sharing for all generics.
However, any generics on your plan’s formulary that were covered during the initial coverage phase of your plan coverage will receive the donut hole discount. And those medications that are covered in the donut hole, will receive the donut hole discount in addition to the coverage.
So for our example, although you have $5 co-pay on some of your generics in the Coverage Gap, those generics will receive the donut hole discount off the $5. All other generics not falling under the $5 co-pay would receive the current donut hole discount (28% in 2014). What kind of discount can we expect in the Doughnut Hole each year?
