The bottom line: AARP offers Medicare Part D plans through UnitedHealthcare, and you don’t have to be a member to enroll. These plans are widely available, and you can choose between a more affordable basic plan and a low-deductible high-end plan. But AARP/UHC’s 2027 member experience ratings are significantly below average, and it offers some of the most expensive plans. Jump to: Full Review

NerdWallet star rating for AARP Medicare Part D plans from UnitedHealthcare
UnitedHealthcare’s prescription drug plans earned 2.9 out of 5 stars from NerdWallet. NerdWallet’s ratings are determined by our editorial team. The scoring formula takes into account premiums, out-of-pocket costs, government quality ratings, customer complaints and more.
Why NerdWallet star ratings differ from CMS star ratings
NerdWallet star ratings go beyond Medicare star ratings developed by the Centers for Medicare & Medicaid Services (CMS).
Our data-driven, consumer-first scoring rubric factors in cost and customer complaints in addition to government quality data. This makes NerdWallet star ratings a more practical tool for seniors looking to find the best overall value.
CMS quality ratings for AARP Medicare Part D plans from UHC
Average CMS star rating, weighted by enrollment: 3
UnitedHealthcare prescription drug plans are rated below the industry average, receiving an average rating of 3 out of 5 from the Centers for Medicare & Medicaid Services (CMS) for 2027, weighted by enrollment. For comparison, the average weighted CMS star rating for all plans is 3.21 stars.
The Centers for Medicare & Medicaid Services (CMS) maintains its own database of star ratings. Medicare Part D plans are rated on 13 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.

AARP Medicare Part D prescription drug plans
There are two AARP Medicare Rx Part D prescription drug plan options available from UnitedHealthcare in 2027:
AARP Medicare Rx Saver: This plan has a $700 deductible that applies to all drug tiers. It has a lower premium than UHC’s other plan, making it better suited for members looking to minimize monthly bills, but it’s still above average compared to other insurers.
AARP Medicare Rx Preferred: This plan has a low deductible that only applies to drugs in Tiers 3-5 in all 50 states and Washington, D.C. People who spend a lot on generics might find it helps them minimize out-of-pocket costs, but the high premiums will likely outweigh any savings. In U.S. territories, Preferred is UHC’s only plan, and it comes with a lower premium and higher deductible than in the states.
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. Over 2.3 million Medicare beneficiaries have AARP Medicare Rx Part D plans from UnitedHealthcare as of October 2026 — a decline of over 1 million members since 2025.
More Nerdy Perspective
Are AARP Medicare Rx plans from UnitedHealthcare good prescription drug plans?
AARP’s Medicare Rx plans have lower member experience ratings and higher premiums than the best Medicare Part D plans. But they are widely available, and if you live in one of the U.S. territories, the AARP Medicare Rx Preferred plan might be one of your only options.
The best prescription drug plan for seniors on Medicare depends on whether and how your prescriptions are covered. You want a plan that comes with monthly premiums and out-of-pocket costs you can afford. Make sure your medications are included on the plan’s formulary, and check how much they’ll cost you before committing to a plan.

Out-of-pocket costs
What you pay for deductibles and copays can vary depending on where your medication falls on the plan’s formulary. A formulary is the plan's list of covered drugs, organized by tiers. Having $0-deductible and $0-copay options can help you minimize your out-of-pocket costs.
Availability can vary by location. Here's what you might pay for prescription drugs at some common price points:
AARP Medicare Rx Saver from UHC
(Everywhere)
Deductible
$700 on all tiers.
Average out-of-pocket cost*
$0 for Tier 1 (preferred generics).
$5 for Tier 2 (generics).
$40.24 for Tier 3 (preferred brands).
AARP Medicare Rx Preferred from UHC
(U.S. states and D.C.)

You can save on your prescriptions by using Optum Home Delivery Pharmacy and Optum Rx — the preferred mail-order pharmacies for AARP Medicare Rx. For example, Preferred plan members in the 50 states and Washington, D.C., pay a $0 copay for a 90-day supply of Tier 1 and Tier 2 drugs through these services.
Cost-sharing requirements for higher tiers can quickly get more expensive. As a result, it’s important to check where your medications and pharmacies fall on each plan’s formulary.
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 2027, the tier at which AARP Medicare Rx plans start requiring coinsurance rather than copays varies depending on plan and, in some cases, location:
Both the AARP Medicare Rx Saver plan and Medicare Rx Preferred plan have copays for Tiers 1-2 and coinsurance for Tiers 3-5 in the 50 states and Washington, D.C.
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: Make sure the medicines you currently take are covered. Talk to your health care providers about what medications to look for. You might also want to check for possible alternatives and/or drugs you think you might need in the future.
Look for plan changes: Formularies (lists of covered drugs) 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 have networks of lower-cost pharmacies. Check to see if the plan's pharmacies are convenient for you. Also, compare prices for using mail order.
You can switch plans during Medicare's open enrollment period, Oct. 15 to Dec. 7. Changes go into effect on the following Jan. 1.
