Seven rules for shopping Medicare Part D plans

Medicare’s Part D benefit is complex, but simple shopping strategies can potentially save enrollees thousands of dollars each year.

As a Medicare beneficiary, you have a multitude of choices to make. From my experience dealing with frustrated Medicare enrollees, I can tell you that selecting the right prescription drug plan is one of the most important. If you make the right choices, they can save you huge sums of of money and headache, while ensuring you have access to the medications you need.

My family is a perfect example: When I sat down with a great uncle a few years ago to take a look at his Part D coverage, it was very quickly obvious that he was overpaying – about $2,000 too much – for coverage for prescription drugs he needed. Even with my immediate family, my father had the right drugs covered but was paying too much – by hundreds of dollars each year.

My family members are just two examples out of the millions of Americans – 39 million in 2015 – who have selected a Part D plan. (That’s about 70 percent of all Medicare beneficiaries.)

Why we needed a Part D benefit

These are people who enrolled in Part D because prescription drugs have historically been one of the expenses that were most concerning to beneficiaries. (About $1 of every $6 Medicare dollars goes toward outpatient prescription drug costs.)

Before Medicare included a prescription drug benefit, many Medicare members had to choose between paying their electric bills or buying groceries and getting their prescriptions filled. Today, the situation is much improved – especially for seniors who take the time to carefully choose a Part D plan that covers their medications – with potential savings in the thousands of dollars each year for people who are wise shoppers.

Medicare beneficiaries access these prescription drug benefits through private Part D plans – the Medicare drug benefit program created in 2003. Because it is based on competition among individual plans, seniors and people with disabilities have many options. Even better news: simply by being an active shopper every year, you can find the best coverage for your needs while saving thousands of dollars.

When tackling Medicare Part D, here are seven rules of the road.

1. Know your shopping window.

You have from October 15 through December 7 to shop around for a new Part D plan or change your Medicare Advantage coverage for the following year.

Because most people can’t change plans outside of this shopping window, it pays to be prepared. Some Medicare members can safely remain in their current plan without increased costs from one year to the next. In fact, some need to remain for other reasons (such as having their best option for Medicare health plan benefits and doctors tied to their Part D coverage, as explained below).

But for many – if not most – Medicare beneficiaries and their caregivers, shopping around for new and better options will invariably save money and ensure you can continue benefitting from the Medicare program’s promise of affordable and accessible health coverage for Americans who need it most.

During your shopping window each fall, it’s important to keep in mind that changes will almost always take effect starting in January, leaving you the option to change your mind more than once during the fall open enrollment window.

2. Check your Medicare Advantage plan.

If you have a Medicare Advantage plan, you usually have to receive your drug benefits through the plan rather than a separate Part D insurer.

In most of the United States, if you are one of the growing number of Medicare beneficiaries who receive their hospital and physicians benefits (Medicare Part A and Part B) through a private Medicare Advantage plan, that same insurer provides your Part D coverage. This means that when you change your Part D plan, your health and hospital benefits change too.

You should consider switching Medicare Advantage plans if your plan’s Part D formulary for next year would limit your ability to continue taking your current prescriptions. Just be sure to choose a replacement Medicare plan that will also cover your current health care providers – in addition to covering your medications. (The same plan comparison tool to select from Medicare health plans also allows you to compare Part D benefits offered by those same insurers – and benefits offered by separate Part D plans, as well.)

Unless you’re really comfortable using a computer and other Internet tools, the best way to select a Part D plan is to contact the government’s 1-800-MEDICARE call center and ask the customer service agent to spend some time and walk you through the process of using’s online Plan Finder to select a new plan. It’s easier to have an agent at Medicare help you through the process than to do it yourself, especially because the online tool itself is not very user friendly.

(As somebody who works in IT, technology holds great promises to make choosing health plans easier for consumers like you. The government is working to do better for seniors, but in the meantime, you can get help from Medicare’s customer service agents – who can guide you through the process of selecting the best plan for your needs.)

3. Check your formularies – and drug costs.

Plans change their lists of covered drugs (formularies) and the drugs’ costs each year. Because prescription drugs are expensive, plans need to change their benefits and can require you to pay more (or less) for the same medication from one year to the next.

Another thing to be aware is that Part D plans can add requirements that you receive the plan’s approval before covering your current medications next January. This is known as prior-authorization or pre-certification.

If you can’t find a plan that covers all your medications, you may be able to work with your doctor to get your existing plan (that has changed your current medication to require pre-approval) to cover the drug anyway. To help speed up the process, you should keep any letters from your Part D insurer if it has approved coverage for one of your medications this year – as evidence to submit support your case.

As an additional safeguard, your Medicare prescription drug insurer must generally offer enrollees a 90-day filling of their current medications when the plan benefits change from one year to the next – under certain circumstances. Because there are conditions attached to this policy, known as a “transition fill,” you should be sure to know your insurer’s rules – while ensuring the plan follows through on its obligations to support you as Medicare beneficiary.

4. It pays to shop around.

Even without major coverage changes, new and different offerings can come to your area, so it still pays to shop around for new plans.

Medicare Part D is the private sector’s first foray into a part of the Medicare program where all benefits are delivered by the private sector. To make Part D coverage palatable to budget analysts in Washington – who need to sign off before lawmakers can create something like a prescription drug benefit – the law’s authors created a “donut hole” (also known as the coverage gap), where you have to pay for most of the costs of your prescriptions. But some plans can save you money during the donut hole, as described in further detail below.

The Affordable Care Act closes the Part D donut hole by 2020 – four years from now. But this is 2016 – and current Medicare members will enter a phase where they have to pay much of the cost of their medications – costing them thousands of dollars they may not have.

5. Part D premiums aren’t everything.

Part D premiums aren’t the whole story – but they are a big part of it. Benefits under Part D before, during and and after you pass through the donut hole change from year to year year. So it pays to closely examine your costs under each plan available, with some plans offering generic drugs without copays. If those offerings apply to your medications, you could save a lot of money throughout the course of they year.

In addition, some Part D plans offer enhanced coverage beyond a minimum level of prescription drug benefits required of insurers by the federal government. This can include softening your cost increases when you enter the donut hole, or eliminating the donut hole altogether. As good as that sounds, enhanced Part D plans may not pay for themselves with lower copays or better coverage in the donut hole – because their higher premiums can more than negate the savings offered by the lower co-pays and deductibles the enhanced plans advertise. This is why it is so important to consider your costs across the entire year, including premiums, co-pays and co-insurance, before making a decision on next year’s Part D plan.

Using Medicare’s own tool (rather than a third party’s tool) allows you to hold Medicare and the Part D plan accountable – and change plans during the benefit year – if you rely on plan information shares with you to make a decision on a health plan, and that information (such as whether the plan covers a certain medication) turns out to be inaccurate. You should be able to ask to change to another plan during the year, if you keep proof that or the plan gave you incorrect information when you were selecting your current plan.

6. Have a lower income? Expect different benefits.

Low-income members including those who have both Medicare and Medicaid can wind up with different benefits. This is important.

You probably know if you have Extra Help (also known as the Low Income Subsidy or “LIS”) with your Part D coverage if your copays for all medications are between $3 and $7 dollars. (Cost sharing for a small segment of enrollees, between 135 and 150 percent of the poverty level, is a fixed percentage rather than a copay, but is still reduced compared to those who don’t receive a Part D subsidy.)

There is more information here on programs that can help you save on your Medicare prescription drug costs and apply for government programs that can help you if you’re in need. It’s important to note that, in addition to having better coverage with lower copays, Part D members with Extra Help also have the ability to change plans up to once per month – even outside of open enrollment.

This doesn’t mean you shouldn’t be proactive about choosing a plan that covers your medications during the regular open enrollment window for Medicare each fall, but it does mean you have some flexibility if something does come up mid-year and you need to change plans again.

7. Part D plan quality is in the stars.

Pay attention to Star Ratings when selecting your plan. Although your primary focus should be whether your medications will be covered, the federal government’s Star Ratings program shows how well a Medicare prescription health or drug plan is doing in a number of ways that impact you.

Good star ratings – especially ratings of four stars and above – can mean a plan has demonstrated quality customer service and has a track record of paying attention to your many health care needs (such as periodic screenings or health assessments). By that same token, you should be wary of plans with fewer than four stars. Those plans often have a track record of mistreating their members, providing subpar customer service, and being slow to process member claims and appeals – delaying or even preventing access to needed health care.

In other words, just be savvy.

The best way to select a Part D plan is to pay attention and be a savvy shopper. You can ask for help doing this – from a friend, neighbor, family member – or an advocate you can access through your senior center or Social Services office.

By taking advantage of resources available to you free of cost, you can be confident you’ll have access to your medications and health care providers, while knowing you selected a plan for next year that is more likely to take care of your needs. Seniors and people with disabilities deserve no less.
