Medicare Advantage ratings come from Medicare itself, not from consumer magazines

Medicare publishes a star rating for every Medicare Advantage plan each year, based on data about customer service, claims processing, and health outcomes. These ratings range from 1 to 5 stars. The highest-rated plans in your area are not necessarily the highest-rated plans nationally — the same plan name may have different star ratings depending on which state or county you live in, because the ratings reflect how that specific plan performed for its members in your location.

You can find your area's highest-rated plans by entering your zip code on Medicare.gov's plan comparison tool. The tool shows you every plan available where you live, sorted by star rating. This is the official source; consumer websites and insurance brokers may list plans, but Medicare's own ratings are what Medicare uses to measure performance.

A higher star rating does not automatically mean lower out-of-pocket costs or better coverage for your specific doctors. A 5-star plan with excellent customer service ratings may have a higher deductible than a 3-star plan, or it may not include your preferred cardiologist. The star rating is one piece of information, not the only piece.

Key Takeaways

  • Medicare publishes star ratings for every Medicare Advantage plan based on customer service, claims processing, and health outcomes, and these ratings vary by location.
  • You can see your area's highest-rated plans by entering your zip code on Medicare.gov's plan comparison tool, which is the official source for ratings.
  • A plan's star rating does not tell you whether your doctors are in the network, what your out-of-pocket costs will be, or whether it covers the services you need most.
  • The highest-rated plan in your area may not be the best plan for your situation — you need to check the network, costs, and coverage alongside the rating.

What the star ratings actually measure

Medicare's star ratings are built from specific measures, not from overall customer satisfaction. The measures include how quickly the plan processes claims, how often members report getting care when they need it, how well the plan manages chronic conditions like diabetes and heart disease, and how members rate their experience with customer service. Each measure gets a score, and those scores combine into the overall star rating.

A plan with a 4-star rating may have excellent claims processing but lower scores on preventive care. A 5-star plan may excel at managing chronic disease but have longer wait times for appointments. The star rating is an average, so you should look at the individual measures if a particular area of care matters to you. Medicare.gov shows the breakdown of each measure for each plan.

Star ratings change every year, usually announced in October. A plan that was 4 stars last year may be 3 stars this year, or vice versa. If you are comparing plans, check the current year's ratings — last year's data is not useful for this year's decision.

How to use the Medicare plan comparison tool to find top-rated plans

Go to Medicare.gov and click "Find care providers and care facilities" or search for "Medicare plan comparison." Enter your zip code. The tool will show every Medicare Advantage plan available in your area, with the current star rating displayed for each one.

You can sort the list by star rating to see the highest-rated plans first. Click on any plan name to see more detail: the individual star measures, the network of doctors and hospitals, the monthly premium, the deductible, copays for common services, and whether the plan covers prescription drugs. This detail page is where you find out whether the plan actually works for your situation.

The tool also lets you enter your current doctors' names to see which plans include them in the network. This step is critical. A 5-star plan does you no good if your primary care doctor is not in the network and you would have to switch.

Comparing the highest-rated plans side by side

Once you have identified two or three of the highest-rated plans in your area, use Medicare.gov's comparison feature to line them up. The tool shows you the premium, deductible, copays, coinsurance, and out-of-pocket maximum for each plan in columns, so you can see the cost differences at a glance.

Pay special attention to the out-of-pocket maximum — this is the most you will pay in a year for covered services. A plan with a lower monthly premium may have a higher out-of-pocket maximum, which means you could end up paying more overall if you need significant medical care. Run the numbers based on your expected health needs, not just the premium.

Check whether each plan covers the prescription drugs you take. Enter your medications into the tool, and it will tell you the copay or coinsurance for each drug under each plan. If you take multiple medications, the total drug cost can vary significantly between plans.

What to do if the highest-rated plan does not include your doctors

If the 5-star plan in your area does not have your primary care doctor or a specialist you see regularly, you have three options: switch to a plan that does include that doctor, even if it has a lower star rating; contact the plan and ask whether your doctor might be added to the network; or check whether your doctor is in-network for other high-rated plans in your area.

Before you rule out a plan because a doctor is not listed, call the plan directly and ask. Network lists on Medicare.gov are updated regularly but sometimes lag behind actual network changes. A doctor may have recently joined the network but not yet appear in the online directory. The plan's customer service line can tell you whether your doctor is currently in-network.

If your doctor is definitely not in the network and will not be added, consider whether you are willing to switch doctors to get a higher-rated plan. This is a personal decision. Some people prioritize continuity of care; others prioritize the plan's overall quality and customer service. There is no wrong answer, but you should make the choice consciously rather than defaulting to the plan you know.

Star ratings versus cost: which matters more

A plan with a 3-star rating and a $0 deductible may cost you less out of pocket than a 5-star plan with a $500 deductible, depending on how much medical care you use. If you are generally healthy and see a doctor once a year, the lower-cost plan may be the better choice even with a lower star rating. If you have multiple chronic conditions and see specialists regularly, the higher-rated plan's better claims processing and care coordination may save you money and hassle despite the higher deductible.

Use the Medicare plan comparison tool to estimate your total costs under each plan: premium plus deductible plus expected copays for your doctors and medications. This gives you a real number to compare, not just a star rating or a premium amount. Some plans publish a "total estimated cost" based on your information, which can help with this calculation.

Star ratings are most useful as a tiebreaker when two plans have similar costs. If Plan A and Plan B both cost you about the same amount out of pocket, and both include your doctors, the higher-rated plan is the safer choice because it has a track record of better service and outcomes.

Where to find help comparing plans if you are unsure

Medicare offers free counseling through the State Health Insurance information Program (SHIP). SHIP counselors are trained to help you understand star ratings, compare plans, and work through your specific situation. You can find your state's SHIP by calling 1-800-MEDICARE or visiting the SHIP locator on Medicare.gov.

Your local Area Agency on Aging may also offer plan comparison help. Many agencies have staff who can walk you through the Medicare.gov tool and answer questions about what the ratings mean. Call your county's Area Agency on Aging to ask whether this service is available in your area.

Insurance brokers who sell Medicare Advantage plans can also help you compare, but remember that they earn commission on the plans they sell. A broker has an incentive to steer you toward plans that pay them higher commissions, not necessarily the highest-rated plan or the best plan for you. If you work with a broker, also do your own research on Medicare.gov so you can verify their recommendations.

Frequently Asked Questions

Does a 5-star Medicare Advantage plan cost more than a 3-star plan?

Not necessarily. Star ratings and premiums are separate. A 5-star plan might have a $0 premium while a 3-star plan costs $50 per month, or vice versa. You have to check both the rating and the cost for each plan in your area. The highest-rated plans are not always the most expensive.

Can I switch to a higher-rated plan if I already chose a Medicare Advantage plan?

Yes. During the Annual Enrollment Period (October 15 to December 7 each year), you can switch to any other Medicare Advantage plan available in your area, including a higher-rated one. If you have a may have access to life event like moving or losing employer coverage, you may be able to switch outside the enrollment period.

What if there are no high-rated Medicare Advantage plans in my area?

Some rural areas have only one or two Medicare Advantage plans available, and they may have lower star ratings. In that case, compare the available plans on cost and coverage rather than rating. You can also consider Original Medicare with a Medigap or Part D plan as an alternative, though that is a different type of coverage.

Do star ratings include information about wait times to see doctors?

Star ratings include some measures related to access to care, but they do not show specific wait times. To find out how long it takes to get an appointment with a doctor in a plan's network, call the plan directly or ask your doctor's office how long their current patients wait for appointments.

If I choose the highest-rated plan, am I may provide good care?

A higher star rating means the plan has performed well on specific measures like claims processing and chronic disease management, but it does not may provide that your individual experience will be perfect. Plans are made up of many doctors and hospitals, and your experience depends partly on which providers you see and how well they coordinate your care.
