Choosing a Medicare Part D plan can feel like a puzzle. You want to keep costs low, but the cheapest monthly premium might not save you money on your specific medications. That’s why you need to compare Medicare Part D drug plans by medication cost , not just by premium. In this guide, we’ll walk you through six top plans, explain how to use the official Medicare plan finder, and give you the tools to pick the plan that fits your needs and budget. We’re Medicare on Video, and we’ve helped thousands of seniors find the right coverage. Let’s get started.
1. Medicare.gov Plan Finder , The Official Comparison Tool
Before you look at any specific plan, start with the most powerful tool available: the Medicare Plan Finder on Medicare.gov. This free online tool lets you enter your list of prescriptions, dosages, and preferred pharmacy. Then it computes your total yearly cost for every available Part D plan in your area , including premiums, deductibles, and copays. It ranks plans from lowest to highest total cost, so you can see which plans save you the most.
Here’s how to use it: create a MyMedicare account so you can save your drug list. Then go to the Plan Finder, enter your ZIP code, and add each medication exactly as prescribed. The tool will show you estimated annual costs for each plan. You can also see star ratings, pharmacy networks, and any restrictions like prior authorization. It’s the most accurate way to compare Medicare Part D drug plans by medication cost because it uses real-time data from the plans.
One thing to know: the tool works best if you have your current drug list handy. If you’re not sure how to use it, the California Health Insurance Counseling & Advocacy Program provides step-by-step instructions on using the Plan Finder.
2. Humana Walmart Value Rx Plan , Low-Cost Option
If you’re looking for an affordable Part D plan with solid coverage, the Humana Walmart Value Rx Plan is a strong choice. Humana is one of the most popular Part D sponsors , in fact, our research shows 3 out of 5 plans highlighted in comparison guides are from Humana. This plan covers more than 3,600 prescription drugs, including many generics at low copays. It’s designed for people who want low cost-sharing on generics and a manageable monthly premium.
What makes the Humana Walmart Value Rx Plan stand out? First, it has a large network of preferred pharmacies, including Walmart and Sam’s Club, where you’ll pay less. Second, it offers a predictable copay structure. You’ll know what you owe at the pharmacy. The plan also has a mail-order option for maintenance drugs, so you can get a 90-day supply delivered to your home.
Keep in mind that even with a low premium, your out-of-pocket costs depend on your specific medications. Use the Medicare Plan Finder to check how much this plan would cost with your drugs. Also note that all Medicare Part D plans share the same $2,100 out-of-pocket maximum in 2026, so once you spend that much, you pay nothing for covered drugs the rest of the year. You can find more details about this plan on Humana’s Value Rx Plan page.
3. SilverScript Choice by CVS Health , Broad Coverage
SilverScript Choice is a Medicare Part D plan offered by CVS Health through Aetna Medicare. It’s known for its broad formulary and wide network of pharmacies, including CVS and many other national chains. This plan is a good option if you take a mix of brand-name and generic medications and want flexibility in where you fill prescriptions.
One of the key benefits is the mail-order pharmacy through CVS Caremark. You can get up to a 90-day supply of maintenance drugs delivered to your door, often at a lower copay than in-store. The plan also has a five-tier formulary, with lower tiers for generics and higher tiers for specialty drugs. Make sure your medications are on the formulary before enrolling.
Watch this video from Medicare on Video that explains how to compare Part D plans and what to look for:
In the video, we break down the costs: for example, one review shows an estimated $393 per year for all brand drugs. That’s a good benchmark, but your costs will vary. SilverScript Choice also qualifies for the Medicare Extra Help program, which can reduce your premium and copays if you have limited income. For more on how drug tiers work, visit Aetna’s drug list check page.
4. Aetna Medicare Rx Select , Complete Benefits
Aetna Medicare Rx Select is another strong contender, especially if you want complete coverage with added perks. This plan covers a wide range of brand and generic drugs and offers benefits like preferred pharmacy networks and mail-order options. It’s available in many states and pairs well with Original Medicare.
One feature that sets Aetna apart is its focus on the Extra Help program. If you qualify, SilverScript Choice (also by Aetna) can lower your plan premium and copays significantly. Aetna also provides clear information about the Inflation Reduction Act, which caps out-of-pocket drug costs and spreads payments across the year.
To give you a quick comparison, here’s a table showing how these plans stack up on key factors:
| Plan | Annual Premium Range | Out-of-Pocket Max | Brand Drug Cost (Est.) |
|---|---|---|---|
| Humana Walmart Value Rx | $0 – $1,070 | $2,100 | $393/year |
| SilverScript Choice | Varies | $2,100 | $393/year |
| Aetna Medicare Rx Select | Varies | $2,100 | — |
| Wellcare Value Script | $0 (in some areas) | $2,100 | — |
| Cigna Secure Rx | Varies | $2,100 | — |
Note that out-of-pocket maximums are the same across all Part D plans , $2,100 for 2026. So the premium doesn’t affect that cap. Check Aetna’s New York plan page for examples of how premiums and costs vary by location.
5. Wellcare Value Script , Low Premiums
Wellcare Value Script is often touted as a $0 premium plan in many areas. That sounds great, but remember: a $0 premium doesn’t mean free drugs. You’ll still pay deductibles, copays, and coinsurance. And you’re still subject to the $2,100 out-of-pocket cap. However, if you take only a few generic medications, this plan can save you a lot on monthly premiums.
Wellcare offers $0 copays on Tier 1 generics at preferred pharmacies like CVS and Walgreens. They also have free mail delivery through Express Scripts for 90-day supplies. The plan covers thousands of drugs, but you need to check if your brand-name medications are on the formulary. Wellcare is part of Centene Corporation and has a large pharmacy network.
One thing to watch: a low-premium plan might have higher copays for brand drugs or more restrictions. Always use the Medicare Plan Finder to compare total costs. For official details, see Wellcare’s prescription drug plan page.
6. Cigna Secure Rx , Reliable Coverage
Cigna Secure Rx is known for reliable coverage and a user-friendly experience. Cigna offers competitive premiums and a broad formulary that includes many popular drugs. The plan also has a strong pharmacy network, including major chains and independent pharmacies. Cigna’s digital tools make it easy to check drug costs and find in-network pharmacies.
One advantage of Cigna is its customer service ratings. Many enrollees appreciate the clear explanations and easy claims process. Cigna also offers mail-order pharmacy services for maintenance medications. If you want a plan that balances cost and convenience, Cigna Secure Rx is worth considering.
According to the Centers for Medicare & Medicaid Services, Part D plans must cover at least two drugs in each therapeutic category. Cigna meets this requirement and often covers more. Check CMS’s Part D information page for official standards.
How to Choose the Right Medicare Part D Plan , Key Factors
Now that you know the top plans, how do you decide? Start by looking at total annual cost, not just the premium. Use the Medicare Plan Finder with your specific drugs. Second, check the formulary: make sure your medications are covered and at what tier. Third, look at the pharmacy network: are your preferred pharmacies included? Fourth, review the star rating , plans with 4 or 5 stars generally offer better service and fewer complaints.
Also, consider the stage of coverage: deductible, initial coverage, coverage gap (donut hole), and catastrophic coverage. In 2026, the coverage gap is eliminated, and after you spend $2,100 out-of-pocket, you pay nothing. That simplifies things. If you qualify for Extra Help, a plan like SilverScript Choice or Aetna Medicare Rx Select can reduce your costs further.
At Medicare on Video, we offer free resources to help you compare plans. Our team can walk you through the process or answer your questions. We also have a detailed guide to Medicare Part D costs that goes deeper into premiums, deductibles, and copays.
Don’t forget to compare plans every year during the Annual Enrollment Period (Oct 15 , Dec 7). Plans change their formularies and costs annually. What worked this year might not be the best next year.
Frequently Asked Questions About Medicare Part D Drug Costs
How do I compare Medicare Part D drug plans by medication cost?
Use the Medicare Plan Finder on Medicare.gov. Enter your list of prescriptions, dosages, and preferred pharmacy. The tool calculates your total yearly cost for each available plan, including premiums, deductibles, and copays. Then sort by lowest total cost. That’s the most accurate way to compare plans based on your specific medications.
What is the out-of-pocket maximum for Medicare Part D in 2026?
The out-of-pocket maximum for all Part D plans in 2026 is $2,100. Once you spend that much on covered drugs in a year, you enter catastrophic coverage and pay nothing for the rest of the year. This cap applies regardless of your plan’s premium.
Can I get a Medicare Part D plan with $0 premium?
Yes, some plans like Wellcare Value Script offer $0 premiums in certain areas. However, a $0 premium doesn’t mean your drugs are free. You’ll still pay deductibles, copays, and coinsurance. Always compare total annual cost, not just the premium.
What happens if I don’t enroll in Part D when I’m first eligible?
You may face a late enrollment penalty. The penalty is 1% of the national base beneficiary premium ($38.99 in 2026) for each full month you were eligible but didn’t have creditable drug coverage. This penalty is added to your premium for as long as you have Part D. Avoid it by enrolling when you first become eligible.
Do all Part D plans cover the same drugs?
No, each plan has its own formulary (list of covered drugs). Plans must cover at least two drugs in each therapeutic category, but specific brand and generic drugs vary. Always check the formulary to make sure your medications are covered and at what tier.
What is the Medicare Extra Help program?
Extra Help is a federal program that helps people with limited income and resources pay for Part D costs. It can lower your monthly premium, annual deductible, and copays. You can apply through Social Security. If you qualify, it can save you hundreds of dollars a year.
