AARP and UnitedHealthcare’s Medigap offerings have advantages and disadvantages.
Plenty of plan types: Eight of the 10 standard Medigap plan types are available to qualifying applicants.
Available everywhere: Plans are available in every state — even Massachusetts, which competitors tend to skip.
Customers are happy: Customers complain about AARP/UHC Medigap plans at relatively low rates.
Extra perks add cost: Plans that include health and wellness discounts sold as "wellness extras" sometimes cost more, while some competitors include similar perks for free.
Confusing plan variations: Some plans are offered with as many as three variations, each with different pricing, extras and restrictions.
Medicare Select networks: UHC/AARP's Medicare Select plans can have lower premiums, but they only work if you can stay in-network for inpatient care.
AARP and UnitedHealthcare offer these Medicare Supplement Insurance plans 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 and UnitedHealthcare offer 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.
“Yes, AARP/UnitedHealthcare Medigap plans are good. They earned our highest score for Medicare Supplement Insurance companies in 2024. I’d still recommend comparing a few companies’ quotes, but AARP/UnitedHealthcare’s combination of strong discounts, low complaint rates and many plan types is hard to beat."
Note: Since Medigap plan options can vary by location, it’s a good idea to do your research, compare multiple quotes and consider working with a licensed insurance agent for more personalized recommendations.
— Alex Rosenberg , lead writer covering Medicare
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 $1,632 in 2024 . 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.
Premiums for AARP Medicare Supplement Plans from UnitedHealthcare aren’t the lowest, but they’re also far from the highest. AARP/UnitedHealthcare’s premiums for Plan G were about 24% higher than the least expensive option in the area, and premiums for Plan N were about 34% higher.

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.

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.

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.

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 13 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.
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.
