Quick answer: AARP Medicare Rx plans are Part D prescription drug plans underwritten by UnitedHealthcare and offered under the AARP name. Like all Part D plans, exact premiums, deductibles, and covered drugs change every year, so always confirm current details directly before enrolling.
What “AARP Medicare Rx” Actually Is
These are standard Medicare Part D prescription drug plans, sold under license to AARP by UnitedHealthcare. That means they follow the same federal Part D rules as any other drug plan — the same 2026 out-of-pocket cap, the same late enrollment penalty rules, and the same annual enrollment windows described throughout this site.
How Part D Plans Like This Generally Work
You’ll typically choose from a few tiers of plans with different monthly premiums, deductibles, and drug tier structures. In 2026, no matter which specific Part D plan you choose, your out-of-pocket costs for covered drugs are capped at $2,100 for the year. See our full breakdown of 2026 Part D costs for how the deductible, coinsurance, and cap work together.
When You Can Enroll
The Annual Enrollment Period runs October 15 through December 7 each year, for coverage starting January 1. If you’re newly eligible for Medicare, you have your own Initial Enrollment Period instead. If you’re already an AARP Medicare Rx member, your plan renews automatically each year unless you make a change during AEP — but it’s still worth reviewing your plan’s costs and covered drugs annually, since these can change from year to year.
Before You Enroll: Check For Assistance First
If your income is limited, check whether you qualify for Extra Help before comparing specific plans — it can significantly lower your premium, deductible, and copays with any Part D plan, not just AARP-branded ones. See if you qualify for Extra Help.
How to Compare Plans Accurately
Because premiums, deductibles, and covered drug lists change every year, the most reliable way to compare AARP Medicare Rx against other Part D options is Medicare’s own Plan Finder tool at Medicare.gov, using your actual medication list and preferred pharmacy. Gather your current prescriptions (names and dosages), then compare total estimated yearly cost — not just the premium — across a few plans before deciding.
