Premiums for Medicare Part D plans can vary based on a number of factors such as age and location. Any prices mentioned above are based on averages reported by Kaiser Family Foundation.¹

Not all plans may be available in all locations. Your monthly premium may be higher if you waited to get Medicare prescription drug coverage. Copay and coinsurance amounts could be higher if you visit an out-of-network pharmacy, depending on what plan you choose.

Medicare Part D Star Ratings

Every year, Medicare evaluates plans based on a 5-star rating system. The Centers for Medicare and Medicaid Services (CMS) uses a star ratings system to rate all Medicare Part D and Medicare Advantage plans.

Criteria used for rating a plan includes:

1. Access to preventive medicine
2. Management of chronic conditions
3. Member experience
4. Member complaints
5. Customer service
6. Drug safety and drug pricing accuracy

When you shop for Medicare prescription drug plans available where you live, you can use the Medicare Star Ratings as one factor you consider to help you find the right plan for you.

A licensed insurance agent can help you compare the Star Ratings of plans that are available where you live. You can also compare the Star Ratings, costs and covered drugs of available plans online.

How to shop for a Medicare Part D plan

Some of the additional features you might find in some Part D plans could factor into your decision about what plan is best for you, such as:

• Mail-delivery service so you can have your drugs shipped right to your home
• Additional coverage in the Medicare Part D coverage gap (or “donut hole”)
• 24/7 customer service

When you’re comparing Medicare prescription drug plans, you may want to consider the following:

• Does the plan cover the drugs you currently take?
• Does the plan’s network include pharmacies that are close to your home or feature a mail delivery service?
• Would you rather pay a higher premium in exchange for a lower deductible and other cost-sharing? Or would you prefer to pay a lower monthly premium and potentially be responsible for more cost-sharing as you use the plan?
• What is the plan’s Medicare Star Rating?

Most Medicare Advantage plans include prescription drug coverage

Don’t forget that many Medicare Advantage plans also include prescription drug coverage.

Medicare Advantage plans provide all of the same benefits as Original Medicare (Part A and Part B). Some Medicare Advantage plans offer additional coverage for things like dental, vision, hearing, transportation and more.

When shopping for a Medicare prescription drug plan, you may want to review any Medicare Advantage plans available in your area that include prescription drug coverage.
