AARP Medicare Part D prescription drug plans are insured by UnitedHealthcare. More than 4 million Medicare beneficiaries have AARP/UnitedHealthcare Part D plans as of April 2022.
Medicare Part D plans from AARP/UnitedHealthcare are widely available and get solid ratings for quality from the Centers for Medicare & Medicaid Services. Pricing for the highest-coverage option can get expensive, however, and the plans’ ratings for helping members with their medications are below average.
Here’s what you should know about Medicare Part D prescription drug plans from AARP and UnitedHealthcare.
AARP/UnitedHealthcare Medicare Part D pros and cons
Medicare prescription drug plans from UnitedHealthcare have advantages and disadvantages.
Available Medicare Part D prescription drug plans
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.
There are three AARP/UnitedHealthcare Part D prescription drug plan options available in 2022:
AARP MedicareRx Walgreens. According to AARP/UnitedHealthcare, this plan is a good fit if you’re “looking for a low premium and can fill your prescriptions at one of more than 9,000 Walgreens and Duane Reade locations.”
AARP MedicareRX Saver Plus. According to AARP/UnitedHealthcare, this plan is a good fit if you “don't take many prescription drugs and are looking for low premiums and copays, and a broad pharmacy network.”
AARP MedicareRx Preferred. According to AARP/UnitedHealthcare, this plan is a good fit if you’re “looking for a plan with robust drug coverage and a broad pharmacy network.”

AARP/UnitedHealthcare Medicare Part D drug formulary tiers
A formulary is a list of the prescription drugs covered by an insurance plan. The plans often organize different kinds of drugs into tiers according to the cost of the drugs.
AARP/UnitedHealthcare prescription drug plans use a five-tier formulary:
Tier 1: Preferred generic
Lower-cost, commonly used generic drugs.
Tier 2: Generic
Many generic drugs.
Tier 3: Preferred brand
Many common brand-name drugs (called preferred brands) and some higher-cost generic drugs.
Tier 4: Non-preferred drug
Non-preferred generic and non-preferred brand-name drugs.
Tier 5: Specialty tier
Unique and/or very high-cost brand and generic drugs.
Each tier has copay or coinsurance requirements, and you’ll pay more for drugs listed in higher tiers.
Which drugs are included in which tiers and what you’ll pay for each tier depends on your choice of prescription drug plan and what kind of pharmacy you use. For example, AARP/UnitedHealthcare plans have the lowest copays for retail and mail-order pharmacies in their preferred network, while you’ll pay more if you use a standard (non-preferred) pharmacy.
Some plans offer $0 copays and waive deductibles for Tier 1 drugs, while higher tiers have coinsurance requirements that can quickly get more expensive. As a result, it’s important to check where your medications and pharmacies fall on each plan’s formulary.
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 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 this 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.
