The bottom line: AARP Medicare Rx plans from UnitedHealthcare are widely available, and the higher-end Medicare Rx Preferred plan costs less than major competitors’ similar plans. But AARP/UHC’s 2025 star ratings are just average, and high premiums for the Medicare Rx Saver plan make it a less competitive option.

AARP Medicare Rx star ratings
Average Part D star rating, weighted by enrollment: 3.16 stars
AARP Medicare Part D plans from UnitedHealthcare get an average star rating of 3.16 stars from the Centers for Medicare & Medicaid Services (CMS) in 2025, weighted by enrollment. For comparison, the weighted average star rating for all stand-alone Part D plans is 3.11 stars.
CMS rates Medicare Part D plans on 12 quality measures. (You can find definitions for each of these factors in the CMS Star Ratings Technical Notes.)
These ratings use a 5-point scale, where 5 is the best and 1 is the worst. The agency bases its ratings on drug plans’ quality of service and customer experiences, and ratings are updated annually.
🤓Nerdy Tip
Medicare star ratings are typically released once per year, but CMS recalculated its 2025 star ratings for AARP/UnitedHealthcare in December 2024. Pursuant to a court order, CMS removed disputed data from the calculations. NerdWallet has updated this review accordingly.
AARP Medicare Part D prescription drug plans
There are two AARP Medicare Rx Part D prescription drug plan options available from UnitedHealthcare in 2025 — down from four in 2024:
AARP Medicare Rx Saver: According to AARP and UnitedHealthcare, this plan is a good fit if you receive Medicare Extra Help subsidies or “want a robust pharmacy network.”
AARP Medicare Rx Preferred: According to AARP and UnitedHealthcare, this plan is a good fit if you “want our most extensive drug coverage and access to a broad pharmacy network.”
The AARP Medicare Rx Walgreens and AARP Medicare Rx Basic plans are no longer offered in 2025.
Medicare beneficiaries with Original Medicare (Part A and/or Part B) can purchase a Medicare Part D plan for prescription drug coverage. Part D plans are sold by private insurance companies. The costs and coverage can vary significantly, so it’s important to compare options.
AARP Medicare Rx Part D prescription drug plans are insured by UnitedHealthcare. About 3.8 million Medicare beneficiaries have AARP Medicare Rx Part D plans from UnitedHealthcare as of November 2024.
💬 From our Nerds: Are AARP Medicare Rx plans from UnitedHealthcare good prescription drug plans?
“Some AARP Medicare Rx plans are stronger options than others in 2025. For higher-coverage plans, the AARP Medicare Rx Preferred plan could be a better value than some competitors’ pricier plans. But the Medicare Rx Saver plan isn’t as competitively priced among 2025’s lower-cost options.
"But remember, the most important thing to know when choosing a Medicare Part D plan is whether and how your prescription drugs are covered. Confirm that your drugs are included on the plan's formulary with out-of-pocket costs you can afford."
— Alex Rosenberg, lead writer covering Medicare

The AARP Medicare Rx Saver plan has a $590 deductible for all covered drugs.
$0-copay options
AARP Medicare Part D plans have relatively few $0-copay options in 2025.
The Medicare Rx Preferred plan has $0 copays for a 90-day supply of drugs on Tiers 1-2 when obtained from a preferred mail-order pharmacy. Drugs from in-person pharmacies, non-preferred pharmacies or on higher tiers all have coinsurance or copay requirements.
There are no $0-copay tiers for the Medicare Rx Saver plan.
Copay vs. coinsurance requirements
You’ll want to check whether you’ll pay a copay or coinsurance for your medications. Copays are set dollar amounts, so it’s easy to see what you’ll pay. Coinsurance is a percentage of the price for your medications, so coinsurance requirements can be less predictable and more expensive.
For 2025, the tier at which AARP Medicare Rx plans start requiring coinsurance rather than copays varies depending on plan and, in some cases, location:
The AARP Medicare Rx Saver plan has copays for Tiers 1-2 and coinsurance for Tiers 3-5.
In the 50 states and Washington, D.C., the AARP Medicare Rx Preferred plan has copays for Tiers 1-3 and coinsurance for Tiers 4-5.
In American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the U.S. Virgin Islands, the AARP Medicare Rx Preferred plan has a 25% coinsurance for Tiers 1-5.
You can enter your medications and pharmacy information on UnitedHealthcare’s website to see which drugs are covered and review your estimated costs with different plan options.

Find the right Medicare Part D prescription drug plan
The interactive tool on Medicare.gov can help you find a Medicare Part D plan that covers your prescriptions. It also helps you compare costs among Medicare Part D and Medicare Advantage plans available to you.
Here are some things to keep in mind when comparing plans:
Check the formulary: You’ll want to make sure the medicines you currently take and, importantly, any you think you might need in the future, are covered under each of the plans you’re considering. Talk to your health care providers about what brand-name and generic medicines to look for and any alternatives that may also work in case you can’t find your current medicines on the plans available in your area.
Look for plan changes: Formularies change frequently. Your insurer should send you a Notice of Plan Change when the formulary changes. Read that document carefully.
Check the pharmacy network: Most Medicare Part D plans negotiate with a network of pharmacies for the lowest cost. Check to see if your pharmacy or an equally convenient one is in the plan’s network. Also, compare prices for using mail order.
If your plan does change, and the change affects the prescription drugs you need, you can switch plans during Medicare's open enrollment period, Oct. 15 to Dec. 7. Changes go into effect on the following Jan. 1.
If you have additional questions about Medicare, visit Medicare.gov or call 800-MEDICARE (800-633-4227, TTY 877-486-2048).
