What is the coverage gap,
and what do I pay?
Medicare cares about what they call your total drug costs.
Your total drug costs are:
- What you pay for the prescriptions on your plan's drug list, PLUS
- What your plan pays for your prescriptions.

If your total drug costs are greater than $2,830 in 2010, you will probably hit the "coverage gap." The coverage gap is sometimes called the donut hole. Then you will pay 100% of your drug costs until your out-of-pocket costs reach $4,550, or your total drug costs hit $6,440.
After that, to get the prescriptions on your plan's list of covered drugs, you will pay either:
- 5% of the costs, while your plan pays 95%, OR
- A co-pay of $2.50 for generic drugs and $6.30 for brand-name drugs.
How might the coverage gap affect my monthly costs?
With most of the Medicare Prescription Drug Plans, you will probably pay different amounts of your drug costs over the course of a year. Some months you will pay less; other months you will pay more. You can budget for those months if you understand how the program works.
- Each month, you will pay your monthly premium, no matter what.
- You must also pay the full cost of drugs until you reach the amount of your deductible.
- After your deductible, you will pay a set percentage of your costs for covered drugs, until you reach the coverage gap.
- The coverage gap starts when the total drug cost - the amount that you and your plan together have paid for covered drugs during the year - reaches $2,830. This does NOT count your premiums or costs for drugs not covered by your plan.
- Once you reach the coverage gap, you must pay the FULL PRICE of drugs yourself. Your plan does not pay anything.
- If the total drug cost for the year reaches $6,440, you reach the level of catastrophic coverage.
- Catastrophic coverage is also triggered if the amount YOU pay for covered drugs out of pocket reaches $4,550. This does NOT count premiums or costs for drugs not covered by your plan.
- Once you reach the level of catastrophic coverage, you will pay at most 5% or less of your costs for covered drugs. Your plan will pay 95%.

The charts below show some examples of what you would pay each month with a sample plan if the cost of your drugs stays the same from month to month. These are only examples. The plan you choose may have very different costs.
