HealthSpring (formerly Cigna) is NerdWallet's pick as the best Medicare Advantage company for low-cost plan availability. HealthSpring has both the highest percentage of $0-premium plans and the lowest average monthly premium among major companies. While its CMS quality ratings are below average, the majority of its members are in highly rated plans. Departing members report more problems than average with coverage of doctors and hospitals, however.
UnitedHealthcare stands out for its large network of providers and hospitals and is included on our list of the best Medicare Advantage companies. Its plans, which are sometimes co-branded with AARP, are available with $0 premiums in 46 states. However, UHC doesn’t always score well on customer experience surveys.

Find the right Medicare Advantage plan
It’s important to do your research before selecting a Medicare Advantage plan for yourself. Here are some questions to consider asking:
What are the plan’s costs? Do you understand what the plan’s premium, deductibles, copays and/or coinsurance will be? Can you afford them?
Is your doctor in-network? If you have preferred medical providers, make sure they participate in the plan’s network.
Are your prescriptions covered? If you’re on medication, it’s crucial to understand how the plan covers it. What tier are your prescription drugs on, and are there any coverage rules that apply to them?
Is there dental coverage? Does the plan offer routine coverage for vision, dental and hearing needs?
Are there extras? Does the plan offer any extra benefits, such as fitness memberships, transportation benefits or meal delivery?

Medicare Advantage review methodology
NerdWallet’s Medicare Advantage ratings are based on premiums, out-of-pocket costs, prescription drug coverage, quality data from the Centers for Medicare & Medicaid Services, consumer experience and more. We calculate each health insurance company’s rating on a curved 5-point scale.
NerdWallet’s editorial team analyzed companies covering about 87% of all Medicare Advantage beneficiaries in the United States. We reviewed 25 Medicare Advantage brands, with some insurance companies having more than one brand under their umbrella. (For example, Blue Cross Blue Shield includes the brands Anthem and Highmark.)
The Medicare Advantage marketplace is concentrated among just a handful of companies. In many places, one company serves more than half of the market. At the national level, NerdWallet’s reviews include each of the 10 largest brands by enrollment.
At the state level, our research includes at least one major insurer in every state where Medicare Advantage plans are sold, and includes the top two insurers in 40 of those 49 states. (Alaska doesn't offer Medicare Advantage plans.) We also look at online search volume to identify regional and other notable players in the space.
These reviews are a guide, but we encourage you to shop around and compare several plans to find the best coverage and rate for you. NerdWallet does not receive compensation for any reviews. Read our editorial guidelines for additional information.
