But if one of your drugs is made by a manufacturer that declines to participate in the discount program, this means your Part D plan won't cover it at all — not in the initial and catastrophic periods of coverage, not in the doughnut hole, and not in the Extra Help program.
Will it take me longer to get out of the gap?
No. The 50 percent discounts from the manufacturers count toward the out-of-pocket spending limit that gets you out of the gap — even though they didn't come out of your pocket. So if your drug costs are high, you reach catastrophic coverage as quickly as you would have without the discounts.
Example: You fill a 30-day prescription for a brand-name drug while in the doughnut hole. The full price is $102 — $100, plus a $2 dispensing fee. The manufacturer's discount brings the price down to $50. You pay $52. But the whole amount of $102 counts toward getting you out of the gap.
However, the discounts on generic drugs (7 percent in 2011) provided by the government do not count toward the doughnut hole limit.
My plan agreed to pay for a drug it doesn't normally cover. Do I get a gap discount?
Yes. If a plan agrees to cover a drug it doesn't normally cover — usually in response to the patient's doctor's request for an exception to its rules — this drug is considered a covered drug for the purpose of discounts in the doughnut hole, and counts toward the dollar limit that gets you out of the gap.
What if my plan already covers some of my drugs in the gap?
Your plan's coverage is applied first, and the discounts are applied to the remaining amount.
What if I'm enrolled in a state pharmacy assistance program?
You still get the discounts in the doughnut hole. They're applied to the price of your drugs before the state assistance kicks in.
What if I already get help from a drug manufacturer?
Check with the manufacturer's patient assistance program to see if its policy has changed.
How will I know if the proper discounts have been applied?
An explanation will be included in the regular statements you receive from your plan. If you have reason to think that the discounts shown are not correct, call the customer service number shown on your membership card. If you disagree with the plan's explanation, you can use the standard appeals process to resolve the issue. You can also call Medicare at 1-800-633-4227 to file a complaint.
Why is there a doughnut hole anyway?
In designing the 2006 Medicare Part D drug coverage, Congress decided to give comprehensive benefits to people with low incomes (Extra Help) or high drug expenses (catastrophic coverage). It was impossible to cover everybody else comprehensively within the $400 billion that Congress had budgeted for the program.
In order to spread the cost burden, just like any other kind of insurance, the law's drafters had to provide at least some upfront coverage for all. Inventing the doughnut hole solved the problem for the government's budget, but created one for many enrollees' pocketbooks.
