What is the Medicare Part D donut hole and how does it affect costs?

• A. The donut hole is a period where beneficiaries pay a higher share of drug costs until reaching catastrophic coverage; this gap has been gradually closing.
• B. There is no coverage change during the donut hole.
• C. The donut hole means you get drugs for free.
• D. The donut hole only affects coverage for vaccines.

Answer: (A)

The question tests understanding of the Medicare Part D coverage gap, often called the donut hole, and how it changes out-of-pocket costs. In Part D, after you pass the plan’s initial coverage limit, you enter a spending phase where you end up paying a larger share of prescription drug costs until you reach the point of catastrophic coverage. That gap was designed to shift more cost onto beneficiaries during high spending, so you would typically pay a bigger portion of the drug costs while in this phase. Over time, reforms have gradually reduced the burden of this gap, with changes that count manufacturer discounts and plan contributions toward the threshold, so the amount you pay while in the donut hole has been decreasing. Once catastrophic coverage kicks in, Medicare covers most remaining costs and you pay only a small amount out-of-pocket. This is why the donut hole is described as a period of higher cost-sharing that has been gradually closing.
