AARP Medicare Supplement Insurance plans
AARP’s Medicare Supplement Insurance plans are insured exclusively by UnitedHealthcare, which is the largest seller of Medicare Supplement Insurance, or Medigap, and of Medicare Advantage plans.
AARP Medicare Supplement Insurance from UnitedHealthcare offers these Medigap plan types in at least some locations for any Medicare member:
Medigap Plan A — the basic benefits included in every Medigap plan without any extras.
Medigap Plan B — basic benefits plus coverage for the Medicare Part A deductible.
Medigap Plan G — the highest-coverage option available to new Medicare members.
Medigap Plan K — the lowest-cost Medigap plan, with 50% coverage for most benefits.
Medigap Plan L — a low-cost option with 75% coverage for most benefits.
Medigap Plan N — a plan with lower premiums but higher copays.
Medigap Plan C and Medigap Plan F are also available for beneficiaries who were eligible to enroll in Medicare prior to 2020. Newer Medicare members can’t buy these plans from any insurance company.
In addition, AARP offers plans in Massachusetts, Minnesota and Wisconsin according to each state's Medigap plan standards, which differ from the standardization system used in the majority of the country.
More Nerdy Perspective
“Yes, AARP Medigap plans are good. They earned our highest score for Medicare Supplement Insurance companies with worthwhile discounts, low complaint rates and many plan types. "Medigap options can vary by location, so I'd recommend comparing a few companies' quotes and/or working with a licensed agent, but UnitedHealthcare and AARP's combination of features is hard to beat."
Medicare Select policies add network requirements
AARP and UnitedHealthcare offer Medicare Select policies in some locations. These plans cover the same Medicare services as any Medigap plan of the same type, but they require beneficiaries to get inpatient services from in-network hospitals and health care providers.
In exchange for the network restrictions, Select plans may offer lower premiums than their non-Select counterparts.
Opting for the Medicare Select version won't save you money in every case. Compare quotes carefully to see what you might save (or not).
If you have a Medicare Select plan and get services from an out-of-network hospital, you become responsible for the Medicare Part A deductible, which is $1,676 in 2025. Exceptions are available for emergency services, services not available from an in-network hospital and when you’re more than 100 miles from home.
Select plans aren’t available in all areas or for all Medigap plan types. Enter your ZIP code on UnitedHealthcare’s website to check what’s available to you and to compare prices for Select and non-Select plans.
Cost for AARP Medigap plans
Premiums for AARP Medicare Supplement Plans from UnitedHealthcare aren’t the lowest, but they’re also far from the highest. AARP's premiums for Plan G were about 17% higher than the least expensive option in the area, and premiums for Plan N were about 29% higher.
- How we evaluate Medigap companies’ prices
The following price estimates were obtained for three metropolitan areas representing above-average, average and below-average costs for the most popular Medicare Supplement Insurance plans (Plan G and Plan N):
Los Angeles: More expensive than average.
Atlanta: Average cost for the U.S.
Dallas: Less expensive than average.
The sections below show estimated pricing information from UnitedHealthcare for a 65-year-old female nonsmoker as filed with the Centers for Medicare & Medicaid Services. (Note: Some Medigap prices may be higher for males.) Prices listed are for base plan types (not Medicare Select plans or any other non-standard option).
For comparison, each table also includes the price for the least-expensive option to buy the same plan from any company that filed prices. For example, AARP/UnitedHealthcare’s lowest estimated price for Medigap Plan G in Los Angeles appears alongside the lowest price on Medicare.gov for all Plan G policies available in Los Angeles to an applicant with identical demographics.
Plan G
AARP/UHC price | Medicare.gov lowest price | |
|---|---|---|
Los Angeles | $173. | $148. |
Atlanta | $153. | $139. |
Dallas | $146. | $117. |
Plan N
AARP/UHC price | Medicare.gov lowest price | |
|---|---|---|
Los Angeles | $146. | $114. |
Atlanta | $137. | $98. |
Dallas | $106. | $88. |
AARP membership
You need to have an AARP membership to enroll in an AARP-branded insurance policy. An AARP membership typically costs $20 per year. Discounts may be available for new members, automatic renewal and/or longer membership terms.
Discounts
Here are several discounts AARP and UnitedHealthcare offer to some Medicare Supplement Insurance applicants:
Multiple policies: Qualifying members can get a discount on monthly premiums if two or more members with the same AARP membership number have eligible AARP-branded Medigap policies. This discount can’t be combined with the household discount.
Household: Qualifying members can get a discount on monthly premiums if they live with another household member who is also an AARP member. This discount can’t be combined with the multiple policy discount.
Electronic funds transfer: Qualifying members can get a discount on monthly premiums for paying with an electronic funds transfer from their bank account.
Available discounts may vary according to factors such as your location, household status and how you apply for a policy.
UnitedHealthcare member complaints
47% fewer complaints than average
Members file complaints about AARP Medicare Supplement Insurance plans at a rate almost 47% below the average for all Medigap plans, according to 2022 and 2023 data from the National Association of Insurance Commissioners for UnitedHealthcare and its subsidiaries that sell Medigap policies.
NerdWallet conducts its data analysis and reaches conclusions independently and without the endorsement of the NAIC.
UnitedHealthcare’s spending on care
84.4% for member benefits
AARP Medigap plans spent 84.4% of premiums on member benefits, according to the most recent annual data. (The other 15.6% went to overhead expenses like administrative costs, marketing, salaries and commissions.) For comparison, the average for all companies is 83.9%.
Medicare Supplement Insurance companies are required to report data on the premiums they collect and how much they spend to provide benefits for members. The minimum required by law for individual Medigap policies is 60%.
Additional benefits
Medigap plans have standardized Medicare benefits, but companies can offer additional perks. Here are examples of extra benefits available with some AARP Medigap policies:
24/7 nurse line: Members can call to speak with a nurse to ask questions, discuss concerns or get help accessing community resources.
Gym memberships: Some plans include gym memberships at no additional cost.
Discounts for dental, hearing and vision: Some plans include discounts on dental services, eye exams, eyewear and hearing devices from certain providers.
Driver safety course: Some plans grant members access to the AARP Smart Driver course. Completing that course might help members qualify for auto insurance discounts.
Note: In some cases, extra perks are included only in plans sold with the “+ wellness extras” label. In most cases, these extras carry an additional cost over a version of the same plan without the extras. However, in some states, such as California, there is no option — plans automatically include the extras even though there’s no “+ wellness extras” label.

Find the right Medicare Supplement Insurance plan
Because Medigap plans are standardized, you can get precisely the same Medicare benefits from any company offering the plan. So when you shop, keep these considerations in mind to find the best policy to fit your needs:
Is your preferred plan available? Health insurance companies don’t always sell every plan, so check who sells the plan you want to buy in your area.
What are the premiums? Prices for the same plan can vary between companies, so check to find the most competitive rates.
Will your premiums change over time? Most policies cost more as you age, but some companies offer policies that let you lock in a price when you sign up.
Are there extras? Medigap plans’ core benefits are standardized, but in certain cases, some companies include such perks as discount programs or gym memberships.
If you have additional questions about Medicare, visit Medicare.gov or call 800-MEDICARE (800-633-4227, TTY 877-486-2048).

Medicare Supplement Insurance ratings methodology
NerdWallet’s Medicare Supplement Insurance (Medigap) ratings are based on pricing, discounts, plan types offered, complaint data from the National Association of Insurance Commissioners, consumer experience, additional perks and benefits, and more. To calculate each health insurance company's rating, we adjusted the scores to a curved 5-point scale, rounded to the nearest half star.
NerdWallet reviewed 15 Medicare Supplement Insurance companies based on highest enrollment and greatest online search volume. At the national level, our scored reviews include companies covering about two-thirds of all Medigap beneficiaries. At the state level, our research includes at least one of the two largest Medigap insurance companies in 48 of the 50 states, plus Washington, D.C.
These ratings are a guide, but we encourage you to shop around and compare several insurance quotes to find the best coverage and rate for you. NerdWallet does not receive compensation for any reviews. Read our editorial guidelines and full ratings methodology for Medicare Supplement Insurance.
Insurer complaints methodology
We examined complaints received by state insurance regulators and reported to the National Association of Insurance Commissioners. To assess how insurers compare to one another, the NAIC calculates a complaint index each year for each subsidiary, measuring its share of total complaints relative to its size, or share of total premiums in the industry. To evaluate a company’s complaint history, we calculated a similar index for each insurance company, weighted by market shares of each subsidiary. We score companies based on this index of how many complaints the company receives relative to its market share. NerdWallet conducts its data analysis and reaches conclusions independently and without the endorsement of the NAIC.
