AARP Supplemental Insurance Cover Guide – AARP Supplemental Insurance, officially known as AARP Medicare Supplement Insurance Plans (also called Medigap), helps millions of Americans with Original Medicare fill the gaps in coverage. Offered through a partnership with UnitedHealthcare, these plans pay for out-of-pocket costs like deductibles, coinsurance, and copayments that Original Medicare does not cover. This comprehensive AARP Supplemental Insurance Cover Guide explains exactly what these plans cover in 2026, who qualifies, how they compare to other options, and how to enroll—based on the latest data from Medicare.gov and official AARP/UnitedHealthcare sources.
If you’re enrolled in Original Medicare Parts A and B and want predictable costs with the freedom to see any Medicare-accepting provider nationwide, this guide is for you.
What Is AARP Supplemental Insurance and How Does It Work?
AARP Medicare Supplement Insurance Plans are standardized Medigap policies endorsed by AARP and insured by UnitedHealthcare. They work alongside Original Medicare: Medicare pays its approved share first (typically 80% for Part B services), and the AARP plan covers the rest according to the specific plan letter you choose.
These plans do not include prescription drug coverage (you’ll need a separate Part D plan), vision, dental, or long-term custodial care. Instead, they focus on reducing your financial risk from hospital stays, doctor visits, and certain emergencies. Plans are guaranteed renewable for life as long as you pay premiums on time and did not provide material misrepresentations during enrollment.
You must be an AARP member to enroll (non-members can join for just $20 per year). Plans are available in most states, though exact offerings and rates vary by location, age, gender, and tobacco use.
2026 Medicare Deductibles and Out-of-Pocket Costs You’ll Face Without Supplemental Coverage
Before choosing a plan, it’s important to understand what Original Medicare leaves you responsible for in 2026:
- Part A (Hospital Insurance) deductible: $1,736 per benefit period
- Part B (Medical Insurance) deductible: $283 per year
- Part B coinsurance: 20% of Medicare-approved amount after the deductible
- Part A hospital coinsurance: $434 per day for days 61–90; $868 per day for lifetime reserve days
- Skilled nursing facility coinsurance: $217.50 per day for days 21–100
Without a Medigap plan, there is no annual out-of-pocket maximum under Original Medicare. That’s why AARP supplemental coverage is popular—it can cap your exposure.
Available AARP Medicare Supplement Plans in 2026
AARP offers the following standardized Medigap plans (lettered A through N). All plans are federally standardized, so benefits are identical regardless of insurer—only premiums differ.
Note: Plans C and F are not available to people who became eligible for Medicare on or after January 1, 2020. High-deductible versions of Plans F and G are offered in some states (you pay the first $2,950 in 2026 before coverage begins).

Who Is Eligible and When Can You Enroll?
You need Original Medicare Parts A and B. Best time to enroll is your 6-month Medigap Open Enrollment Period (starts the month you turn 65 and are enrolled in Part B)—no medical underwriting required. Guaranteed-issue rights also apply in certain situations (e.g., losing employer coverage).
Under-65 disabled or ESRD beneficiaries may qualify in some states.
How to Enroll in AARP Supplemental Insurance?
- Confirm you have Original Medicare Parts A and B.
- Join or verify AARP membership ($20/year if needed).

You can switch plans during certain periods, but medical underwriting may apply outside open enrollment.
AARP Supplemental Insurance vs. Medicare Advantage
Medicare Advantage (Part C) often bundles Part D, vision, and dental but usually has networks, prior authorizations, and annual out-of-pocket maximums. AARP Medigap + Original Medicare + Part D gives you maximum flexibility and no network restrictions—ideal if you travel or see multiple specialists.
