More than 1.7 million people in New Jersey are signed up for Medicare, placing it in the top 15 U.S. states for Medicare beneficiaries.
Medicare is the federal health insurance program for people age 65 and older. Medicare Advantage is a bundled alternative to Medicare sold by private companies. It offers all the same benefits and usually some extras, such as cost savings on dental and vision coverage.
Medicare Advantage plans offer more benefits than Original Medicare, and they can be cheaper than paying for Medicare and a Medicare Supplement plan. However, they have less flexibility since you’ll need to get care from within the plan’s network of providers. Weigh your options to determine which plan best suits your needs.

December update
Medicare star ratings are typically released once per year, but CMS recalculated its 2025 star ratings for UnitedHealthcare and Centene companies in December 2024. Updates took place after multiple lawsuits from insurance companies alleging that CMS improperly calculated the 2025 star ratings. NerdWallet has updated this article accordingly.

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 a preferred medical provider or 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?
If you have additional questions about Medicare, visit Medicare.gov or call 800-MEDICARE (800-633-4227, TTY 877-486-2048).

Medicare Advantage review methodology
The Medicare Advantage marketplace is concentrated among just a handful of companies; in many places, one insurer serves more than half of the market. NerdWallet reviewed 26 Medicare Advantage brands, with some insurers having more than one brand under their umbrella. (For example, Blue Cross Blue Shield includes the brands Anthem and Highmark.) At the national level, these reviews include nine of the 10 largest brands by enrollment. At the state level, our research includes at least one major insurer in 47 of the 49 states that offer Medicare Advantage plans, and includes the top two insurers in 35 of those 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.
NerdWallet’s Medicare Advantage reviews are based on ratings data from the Centers for Medicare & Medicaid Services, as well as pricing, plan availability by state, plan types available, consumer experience, extra benefits offered and more. 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.
