Medicare Advantage plans replace Original Medicare (Part A and B, and often D). Benefits extend beyond Original Medicare, including an annual out-of-pocket expense limit and dental, vision, and hearing coverage. In exchange (and unlike Original Medicare), you generally must use in-network providers and services.
Commercial insurance companies administer MA plans. Costs and benefits differ, so shopping around and comparing plans is essential.
To choose the best Medicare Advantage companies, we evaluated nine major health insurance companies for 22 criteria that fall into categories including plan and care quality, cost, Medicare drug gap coverage, and state availability.

Most plans offer additional drug coverage during the Medicare donut hole, which can save money if your drugs cost more than $5,030 in 2024.
UHC outperforms its peers in key metrics, but the average out-of-pocket expense is $5,579 in 2024. This amount is higher than some competitors’ but lower than the average across major insurers.Read more in our UnitedHealthcare Medicare review.
UnitedHealthcare Group is being sued for allegedly using a flawed artificial intelligence algorithm that denies rehabilitation care for Medicare Advantage patients, despite knowing that the algorithm has a 90% error rate.
Lowest Cost : Cigna
- Lowest overall-cost plans compared to the largest providers
- Lowest average premium compared to the largest providers
- No PFFS plans

This is important because once you and your plan spend $5,030 on drugs in 2024, you’ll pay up to 25% on brand-name drugs and generics. Then, after you spend $8,000 out of pocket on drugs, you leave the donut hole.
Aetna came in second in our evaluation of nationwide costs for MA plans, which looks at average premiums, drug deductibles, and out-of-pocket expenses. But if you live in Alaska, Hawaii, Montana, or Vermont, or want a PFFS plan (private-fee-for-service), you'll need to consider another Medicare Advantage provider.Read more in our Aetna Medicare review.
Best for Patient Quality and Customer Satisfaction : Kaiser Permanente
- Highest average NCQA rating of the major providers
- Highest Medicare star rating of the major providers
- Lowest deductibles, on average, compared to all other major providers

Bottom Line
To choose the best Medicare Advantage company, consider what you need from a plan. Are you comfortable with an HMO, or do you require additional flexibility? For instance, if you want a PFFS plan, there are a few providers to consider, including UnitedHealthcare and Humana.
If cost is your primary concern, consider Cigna. But beware that its Medicare star rating is below average. Or would you rather pay more monthly for a higher level of quality and customer satisfaction? Check out UHC's AARP plans, Aetna, and Kaiser, if it’s available in your area. Do you want a plan with drug coverage? If so, how much do you expect to spend on prescription drugs, and which specific drugs do you use? lets you input the drugs you use when comparing plans to see which provides the best coverage. You can also see which specific plans offer additional coverage in the Medicare donut hole. Individual Medicare Advantage plans have their own Medicare star ratings—we looked at national company averages. So, even if you choose a top-ranked company like UnitedHealthcare, ensure the specific MA plan you’re interested in has a rating you’re comfortable with. That information is also available in the plan finder tool.Frequently Asked Questions
-
What Is the Medicare Donut Hole or Coverage Gap?
The Medicare coverage gap or "donut hole" refers to a period when there is a limit on prescription drug coverage. It begins once the Medicare Advantage plan member spends $5,030 on covered drugs. During this time, Medicare asks members to be responsible for up to 25% of drug costs. But some plans offer additional coverage in the gap, such as $0 copays on preferred brand name drugs and generics. In 2024, the gap ends once the member spends $8,000 on covered drugs.
-
What Is the Highest-Rated Medicare Advantage Plan?
Kaiser Permanente’s 2023 Medicare Advantage plans receive 5 stars from the Centers for Medicare and Medicaid Services (CMS) in California, Colorado, Georgia, Hawaii, and Mid-Atlantic states (Maryland, Virginia, and Washington, D.C.). The CMS ranks Medicare Advantage and prescription drug plans from 1 to 5 stars, with 5 stars being the highest or best rating. A plan’s star rating reflects its performance based on enrolled people’s experiences.
-
What Is the Biggest Disadvantage of Medicare Advantage?
A primary Medicare Advantage plan drawback is that these plans typically require you to use dedicated networks, such as an HMO or PPO. As a result, geographic coverage and provider choice is limited. Original Medicare doesn’t restrict you to a network; you can choose any provider accepting Medicare.
-
Can I Drop My Medicare Advantage Plan and Go Back to Original Medicare?
Yes, you can switch back to Original Medicare during the annual Medicare Open Enrollment period from October 15 to December 7. Your Original Medicare coverage will go into effect on January 1. Or, you can switch during Medicare Advantage Open Enrollment from January 1 to March 31. Your new coverage becomes effective on the first day of the month after joining the plan.
How We Chose the Best Medicare Advantage Providers
To identify which Medicare insurance companies to review, we analyzed business and market insight databases including Statistia, Plunkett, and Gale. We also considered user-generated data from Google to determine public interest and trends in Medicare plans.We collected data from third-party rating agencies like the credit rating agency AM Best and the National Committee for Quality Assurance (NCQA), an independent organization that rates health insurance plans on quality and customer satisfaction. We also gathered data from government websites and databases provided by the Centers for Medicare and Medicaid Services (CMS) such as CMS.gov and HealthCare.gov, and directly from companies via websites, media contacts, and existing partnerships. The data collection process spanned Sept. 15 to Sept. 29, 2023.
We then developed a quantitative model that scores each Medicare Advantage provider based on four major categories and 22 criteria that are crucial in evaluating the company's offerings and benefits. We weighted the four categories as follows for this article:- Plan features: 35%
- Plan quality and customer satisfaction: 30%
- Cost: 20%
- Availability: 15%
