AARP Medicare Supplement Plans Explained for Smart Choices
Understanding AARP Medicare Supplement (Medigap) Plans: Bridging the Gaps in Original Medicare
What Are Medigap Plans and How Do They Work with Original Medicare?
AARP Medicare Supplement Insurance Plans—commonly known as Medigap—are designed to help cover the out-of-pocket costs left behind by Original Medicare. Medicare Part A and Part B pay for many services, but not everything. That’s where Medigap comes in: it helps pay for coinsurance, copayments, and deductibles, so your out-of-pocket expenses are more predictable. Medigap plans do not replace Medicare Parts A and B. Instead, they work alongside Original Medicare to provide additional coverage. When you receive care, Medicare pays its share of approved amounts first, and your Medigap plan kicks in to pay the rest, based on your plan.
The Role of UnitedHealthcare and AARP Membership Requirement
AARP Medicare Supplement plans are insured by UnitedHealthcare, a trusted leader in the health insurance industry. While the plans are branded under AARP, you must be an AARP member to enroll. Membership is open to anyone aged 50 or older and has a nominal yearly cost—$20 annually starting in 2025, with a discounted $15 fee for new members in their first year.
Standardization of AARP Medigap Plans Across States and Exceptions
Federal regulations require that all Medigap plans (Plan A through N) with the same letter offer identical basic benefits, regardless of the insurance company or your location—except in Massachusetts, Minnesota, and Wisconsin, which have their own standardized alternatives. However, premiums and plan availability can differ by state, which makes it crucial to compare carefully during enrollment.
Coverage Benefits and Key Features of AARP Medicare Supplement Plans
Coverage of Out-of-Pocket Costs: Coinsurance, Copayments, and Deductibles
Original Medicare leaves beneficiaries responsible for approximately 20% of medical costs through coinsurance and does not have a cap on out-of-pocket spending. AARP Medigap plans help alleviate these expenses by covering:
- Part A inpatient hospital coinsurance
- Part A deductible
- Part B coinsurance or copayment
- First three pints of blood
- Part B excess charges (depending on the plan)
Hospital Stay Coverage: Part A Coinsurance, Deductibles, and Extended Benefits
After the first 60 days of hospitalization, Medicare Part A requires a coinsurance of $419 per day for days 61–90 (as of 2025). After that, lifetime reserve days cost $838 per day. AARP Medigap plans cover these amounts and offer up to 365 extra days of hospital coverage when your Medicare benefits run out.
Skilled Nursing Facility and Hospice Care Coverage
Plans such as G, N, and F include coverage for skilled nursing facility coinsurance and hospice care coinsurance or copays. Considering how expensive rehabilitative therapy can be, this is a significant benefit for those recovering from surgery, illness, or injury.
Foreign Travel Emergency Coverage: What It Includes and Who Benefits
For snowbirds, retirees who vacation abroad, or those who travel frequently internationally, foreign travel emergency (FTE) coverage is essential. Plans G, F, and N include FTE coverage—up to 80% of emergency costs, with a $250 deductible and a $50,000 lifetime limit.
Freedom to Choose Providers with No Network Restrictions
One of the biggest advantages of Medigap is that you can visit any doctor or hospital in the U.S. that accepts Medicare. There are no network restrictions, giving you full control over your providers. This is especially helpful for individuals who move or travel frequently.
Overview of Plan Letters and Their Standardized Benefits (A, B, G, N, etc.)
Each Medigap plan type—identified by letters—offers a unique mix of benefits. Plan G has grown in popularity as a comprehensive option, especially since Plan F is no longer available to new Medicare enrollees post-2020. Plan N offers lower premiums with copays, while Plans K and L include cost-sharing with annual limits.
Latest Updates and 2025 Changes Impacting AARP Medicare Supplement Plans
Updated Premium Structures and AARP Membership Fees in 2025
While premium amounts vary by age, location, and health status, one universal requirement remains: AARP membership. Starting in 2025, this costs $20 annually, or $15 for the first year. Make sure to factor this into your budget when planning healthcare expenses.
Changes to Deductibles, Coinsurance, and Out-of-Pocket Limits for 2025
With inflation and healthcare costs rising, the following 2025 updates are noteworthy:
- Part A deductible: $1,676 per benefit period
- Coinsurance for days 61–90 in hospital: $419/day
- Lifetime reserve hospital days: $838/day
- Plan K out-of-pocket limit: $7,220
- Plan L out-of-pocket limit: $3,610
Plan Availability Updates: Restrictions on Plans C and F Enrollment
If you became eligible for Medicare on or after January 1, 2020, you are not eligible to enroll in Plan F or Plan C. These plans cover the Part B deductible—a benefit no longer available to new enrollees under current law.
Understanding Annual Out-of-Pocket Limits in Plans K and L
Unlike other Medigap plans, Plans K and L share costs with beneficiaries until they hit an annual cap—$7,220 and $3,610 respectively in 2025. These can be cost-effective for those who don’t expect high medical usage.
How These Changes Affect Your Choice and Budget Planning
Understanding these annual updates ensures you’re not caught off-guard by unexpected costs. Choosing the right plan can significantly impact your healthcare budget, especially if you’re on a fixed income.

AARP Medigap Plans vs. Medicare Advantage: Which Option Fits Your Lifestyle?
Key Differences in Provider Access and Coverage Scope
Medigap plans work alongside Original Medicare and allow access to any provider nationwide that accepts Medicare. Medicare Advantage (MA), often HMOs or PPOs, restrict you to network providers.
Out-of-Pocket Protection and Cost Predictability Comparison
Medigap plans provide more cost predictability by covering gaps, while MA plans may include deductibles, copays, and annual limits.
Prescription Drug Coverage: Separate Part D vs. Bundled Plans
Medigap plans do not include drug coverage. You’ll need to enroll in a separate Part D plan. If you’re unfamiliar with Part D, check out this guide on what is Medicare Part B and drug coverage basics.
Extra Benefits like Dental and Vision: What’s Included?
MA plans often include additional perks like dental, vision, and fitness, while Medigap plans focus only on medical expenses.
Can You Combine Medigap and Medicare Advantage? Understanding Enrollment Restrictions
You can’t use Medigap and Medicare Advantage simultaneously. Choose one based on your preferred provider flexibility and benefit structure. Learn more about Advantage plans in this article on what is Medicare Part C.
