An explanation of the 2017 Medicare Part D Coverage Gap or Donut Hole.

The Medicare Part D Coverage Gap or Donut Hole was actually similar to a second deductible in an insurance policy where, after receiving a certain level of coverage, you were responsible for paying your own drug coverage. However, with the introduction of the Donut Hole discount in 2011, you are now responsible for only a portion of your own drug coverage in the Donut Hole. In 2020, the Coverage Gap will be considered "closed" when both generic and brand-name drugs will cost Medicare Part D plan members 25% of the retail drug price (so you will pay $250 for a medication with a $1,000 retail cost).

How does the Donut Hole work in 2017?

The 2017 Donut Hole generic drug discount will increase from 42% to 49%.

This means: You will save more on generic medications in the 2017 Coverage Gap. As an example, if you reach the 2017 Donut Hole phase of your Medicare Part D plan, and your generic medication has a retail cost of $100, you will pay $51. The $51 that you spend will count toward your out-of-pocket spending limit or TrOOP.

The 2017 Donut Hole discount for brand-name drugs will increase to 60% and you will receive credit for 90% of the retail drug cost toward meeting your 2017 total out-of-pocket maximum (TrOOP) or Donut Hole exit point (the 40% you spend plus the 50% drug manufacturer discount).

This means: You will have additional savings on brand-name drugs in the 2017 Coverage Gap. For example, if you reach the 2017 Donut Hole and purchase a brand-name medication with a retail cost of $100, you will pay $40 for the medication, and receive $90 credit toward meeting your 2017 out-of-pocket spending limit – or Donut Hole exit point.

As a reminder, your Medicare Part D plan coverage has four separate parts or phases:

(1) The Initial Deductible Phase (unless your plan has a $0 deductible and you skip directly to the Initial Coverage Phase): If your Medicare Part D plan has an Initial Deductible, you will usually pay 100% for your medications and the amount you pay will count toward the Donut Hole. However, some Medicare Part D prescription drug plans are now covering your generic medications in the Initial Deductible. So, whether you or your plan pays for your medications in the Initial Deductible, the retail value of your medications counts toward your Initial Coverage Limit (see next section) and entering into the Donut Hole or Coverage Gap.

The standard Initial Deductible can change each year. In 2016, the Initial Deductible was $360 - in 2017, the Initial Deductible is $400.

(2) The Initial Coverage Phase: After the Initial Deductible (if any), you will continue into your Initial Coverage Phase where your Medicare Part D plan covers a portion of your prescription costs and you pay some cost-sharing (co-payment or co-insurance). You will leave your Initial Coverage Phase and enter the Donut Hole or Coverage Gap when your retail medication costs reach a certain amount (not the amount of what you paid for your drugs, but the retail value of the medications you purchased - for instance, if you buy a medication with a retail value of $100 for a $30 co-payment, the $100 retail value counts toward your Initial Coverage Limit).

The Initial Coverage Limit can change each year. In 2014, the Donut Hole entry point began when a person's total retail drug costs exceeded $2,850 - in 2015, the Donut Hole entry point began when retail drug costs exceeded $2,960 - in 2016, the Initial Coverage Limit or Donut Hole entry point is when retail drug costs exceed $3,310 - in 2017, the Initial Coverage Limit or Donut Hole entry point is when retail drug costs exceed $3,700.

Bottom Line: If the retail cost of your medications is over $308 per month, you will enter the 2017 Donut Hole.

Please note, if you use an expensive medication, you may find that one large drug purchase (or multiple drug purchases in a single month) can actually move you from the Initial Coverage Phase into the Donut Hole, so the only way to know exactly when you will enter or leave the doughnut hole is by watching your monthly Medicare Part D plan's Explanation of Benefits statement carefully (you received this printed form in the mail) or you can contact your Medicare Part D plan and ask the Member Services representative where you are relative to the plan's Coverage Gap.

(3) The Coverage Gap or Donut Hole: As mentioned, this is the portion of your Medicare Part D coverage where you pay a larger percentage of the retail drug cost. From 2006 through 2010, you were responsible for 100% of your drug costs, unless your Medicare plan included some Donut Hole coverage. Since 2011, you receive some discount on your Medicare Part D plan purchases while in the Donut Hole.

The 2017 Donut Hole discount is 60% for brand-name drugs (you pay 40%) and 49% for generic drugs (you pay 51%). For more information about the Donut Hole discount, you can click here to see how the Donut Hole discount increases over the next few years until, in 2020, the discount reaches 75% and the Donut Hole is considered “closed”.

How much could you save on brand-name medication purchases while in your 2017 Donut Hole?
About $2,458.50 - maybe even a little more depending on your Medicare Part D plan. You can click here to read more.

(4) The Catastrophic Coverage Phase: You will stay in the Donut Hole phase until your out-of-pocket costs (also called TrOOP or total drug spend) reaches a certain level. The TrOOP level in 2017 is $4,950. So if you have spent $4,950 on Medicare Part D drugs (not including monthly Medicare plan premiums), you will exit the Donut Hole and enter the Catastrophic Coverage phase.

TrOOP is the total of what you pay during the Initial Deductible (if you have one) plus what you personally pay in the Initial Coverage Phase, before the Donut Hole, plus what you pay in the Donut Hole (and plus you get credit for the 50% brand-name discount paid by the drug manufacturer in the donut hole - for instance, if in the 2017 Donut Hole you buy a brand-name drug with a $100 retail value, you pay the $40 discounted price, but actually get credit for $90 toward meeting your TrOOP limit).

Your TrOOP limit can change every year: the TrOOP limit in 2014 was $4,550 - TrOOP in 2015 was $4,700 - TrOOP in 2016 was $4,850.

A note on TrOOP vs. Retail Cost: Without considering your Donut Hole discount, your 2017 TrOOP (true or total out-of-pocket costs) should equate to about $7,425 in retail drug costs. But with the Donut Hole discount, Medicare estimates that your retail drug cost should be around $8,071.16 before exiting the 2017 Donut Hole. The estimate is based on historic brand-name and generic drug purchases while in the Donut Hole.

Bottom Line: If your monthly retail drug costs are somewhere around $673, you probably will spend your way through the 2017 Donut Hole and enter your Medicare Part D plan's 2017 Catastrophic Coverage phase.

Once you enter the 2017 Catastrophic Coverage portion of your Medicare Part D plan, you pay the greater of 5% or $3.30 for generic drugs (or preferred drug that is a multi-source drug) or the greater of 5% or $8.25 for all other drugs (such as brand-name medications). For example, if you purchase a brand-name medication in the 2017 Catastrophic Coverage phase that has a retail cost of $100, you will pay $8.25 (since this fixed cost of $8.25 is higher than $5.00 ($100 * 5%).

Here is how a formulary drug purchase is calculated throughout your 2017 Medicare Part D plan (using the CMS defined standard benefit Medicare Part D plan as a guide).

When you purchase a formulary medication with a $100 retail cost in 2017
Retail Cost	You Pay	Medicare Plan Pays	Pharma Mfgr Pays	Gov. Pays	Amount toward your TrOOP
Initial Deductible	$100	$100	$0	$0	$0	$100
Initial Coverage Phase *	$100	$25	$75	$0	$0	$25
Coverage Gap - brand-name **	$100	$40	$10	$50	$0	$90
Coverage Gap - generic ***	$100	$51	$49	$0	$0	$51
Catastrophic Coverage (brand drug) ****	$200	$10	$30	$0	$160	n/a
Catastrophic Coverage (generic drug) ****	$100	$5	$15	$0	$80	n/a

* 25% coinsurance or cost-sharing
** 60% Brand-name Discount
*** 49% Generic Discount
**** you pay 5% of retail or $8.25 for brand drugs whatever is higher or 5% of retail or $3.30 for generic or multi-source drugs whatever is higher (80% paid by Medicare, 15% paid by Medicare plan, and around 5% by plan member)

No matter where you are at the end of the plan year, your Medicare Part D plan coverage ends on December 31st and the whole process begins again on January 1st of the next year. To help you visualize the phases of your Medicare Part D prescription drug plan coverage, we have a Donut Hole Calculator or 2017 PDP-Planner online illustrating the changes in your monthly estimated costs based on the established 2017 standard Medicare Part D plan limits mentioned above.

We also have several examples online to help you get started with our 2017 PDP-Planner tool. You can click here for an example of a Medicare beneficiary with relatively high monthly prescription drug costs (retail prescription drug cost of $800 per month) and then change the monthly drug cost to whatever you wish.
