There is no single best Medicare Advantage plan for everyone

The "best" Medicare Advantage plan depends entirely on your doctors, your medications, where you live, and how much you are willing to pay out of pocket. A plan that works perfectly for your neighbor may have your doctor out of network or cost you thousands more per year. Medicare Advantage plans vary by county — the same plan name may have different networks and costs in different states, and some plans do not exist in your area at all.

The only way to find the right plan for you is to check three things: whether your current doctors are in the plan's network, what your total yearly costs would be (premiums, deductibles, and copays combined), and whether the plan covers your medications at a price you can afford. This takes about an hour per plan, but it is the only comparison that matters.

Key Takeaways

  • Medicare Advantage plans are county-specific, so you must check plans available in your zip code, not plans available nationally.
  • The lowest premium is rarely the lowest total cost — you need to add premiums, deductibles, copays, and medication costs to compare fairly.
  • Your doctors must be in the plan's network, and you should call the plan to confirm they are accepting new patients, not just listed as in-network.
  • You can change plans once per year during the Annual Enrollment Period (October 15 to December 7), so choosing imperfectly is not permanent.
  • Medicare.gov's plan comparison tool lets you enter your doctors and medications and see actual costs for each plan in your area.

How to check if your doctors are in network

Before you compare anything else, verify that your primary care doctor, any specialists you see regularly, and your hospital are in the plan's network. A plan with a $0 premium is worthless if your cardiologist is out of network and costs you $200 per visit.

Go to the plan's website and use their provider search tool. Search by name and location. If your doctor appears, note the network status — some plans have "preferred" and "standard" networks with different copays. Then call your doctor's office directly and ask: "Are you accepting new Medicare Advantage patients from [plan name]?" Websites lag, and doctors sometimes stop accepting a plan even though they still appear as in-network.

If your main doctor is not in any plan available in your area, you have a choice: switch doctors to someone in-network, or stay on Original Medicare instead of Medicare Advantage. There is no penalty for staying on Original Medicare, though you will need a separate prescription drug plan (Part D).

Calculate your total yearly cost, not just the premium

Medicare Advantage plans advertise their monthly premium, but that is only one piece of your cost. You also pay a deductible (usually $0 to $500), copays for each doctor visit (usually $0 to $50), coinsurance for hospital stays, and out-of-pocket maximums that can reach $7,550 per year. A plan with a $0 premium and a $500 deductible plus $40 copays will cost you far more than a plan with a $50 premium and $0 deductible plus $10 copays — but only if you actually use those services.

Use Medicare.gov's plan comparison tool. Enter your zip code, your doctors' names, and the medications you take. The tool will show you the estimated total cost for each plan based on your actual prescriptions and your doctors' typical visit frequency. This estimate is not perfect, but it is far more accurate than comparing premiums alone.

Write down the total yearly cost for your top three plans. Include the monthly premium times 12, the deductible, and the average copay costs the tool estimates. Then compare the three numbers side by side.

Understand what "out of pocket maximum" means

Every Medicare Advantage plan has an out-of-pocket maximum — the most you will pay in a single year for covered services. Once you reach that number, the plan pays 100% of covered costs for the rest of the year. The out-of-pocket maximum for 2024 is capped at $7,550 for in-network services, though some plans set it lower.

This matters most if you have a chronic condition that requires frequent visits or expensive medications. If you take three medications that cost $200 per month each, you will hit your out-of-pocket maximum quickly, and the plan will cover the rest of the year free. If you rarely see a doctor, you may never reach it, so a plan with a higher out-of-pocket maximum but lower copays might save you money.

When you compare plans, check both the out-of-pocket maximum and the copay structure. A plan with a $5,000 out-of-pocket maximum and $50 copays might cost you less over the year than a plan with a $7,550 out-of-pocket maximum and $10 copays, depending on how many visits you actually make.

Check prescription drug coverage carefully

Medicare Advantage plans include prescription drug coverage (Part D), so you do not buy a separate drug plan. However, not all plans cover all medications, and the copay for the same drug varies widely between plans. Some plans charge $10 for a generic blood pressure medication; others charge $50.

On Medicare.gov, enter each medication you take — the name, strength, and quantity. The tool will show you the copay for that exact medication in each plan. If you take five medications, you may see copays ranging from $5 to $40 per medication depending on the plan. Multiply that by 12 months to see the yearly difference.

If a plan does not cover one of your medications at all, ask your doctor whether a similar medication in the plan's formulary (approved drug list) would work for you. Sometimes switching to a covered alternative saves you hundreds per year. If no alternative exists and the plan does not cover your medication, that plan is not a good choice for you.

Know the difference between HMO and PPO plans

Most Medicare Advantage plans are either HMO (Health Maintenance Organization) or PPO (Preferred Provider Organization). The main difference is flexibility: HMO plans require you to use doctors in their network and usually require a referral to see a specialist. PPO plans let you see any doctor, but you pay more if you go out of network.

HMO plans typically have lower premiums and copays because they are more restrictive. PPO plans cost more but give you more freedom to choose doctors. If you travel frequently or see specialists outside your area, a PPO plan may be worth the extra cost. If you are happy with your current doctors and do not travel, an HMO plan usually saves you money.

Some areas have only HMO plans available, and some have only PPO. Check what is available in your zip code before you decide which type you prefer.

When and how to switch plans

You can change Medicare Advantage plans once per year during the Annual Enrollment Period, which runs from October 15 to December 7. Changes take effect on January 1. You can also switch to Original Medicare during this same window, though if you do, you must also choose a separate Part D drug plan.

If you move to a new state or county, you may be able to change plans outside the enrollment period. If your plan leaves your area or drops your doctor, you may also have a special enrollment period to switch. Call Medicare at 1-800-MEDICARE to ask whether you may have access to for an exception.

To switch plans, go to Medicare.gov, log into your account, and select a new plan during the enrollment period. You do not need to contact your current plan — Medicare handles the switch automatically. Your new coverage starts January 1.

Frequently Asked Questions

Can I switch back to my old plan if I do not like the new one?

Only during the next Annual Enrollment Period (October 15 to December 7). If you switch in January and realize by March that you made a mistake, you are locked in until the following October. This is why it is worth spending time on the comparison now — you cannot easily undo a bad choice mid-year.

What if my doctor leaves the plan's network after I sign up?

You have a special enrollment period to switch to a different plan if your doctor leaves the network. Call Medicare at 1-800-MEDICARE as soon as you learn your doctor is leaving, and they will tell you what options you have and whether you can switch outside the normal enrollment window.

Do all Medicare Advantage plans cover dental and vision?

Many plans include some dental and vision coverage, but it is usually limited — a cleaning or exam per year, not major work. Check the specific plan's coverage details on Medicare.gov. If you need significant dental or vision work, factor that into your cost comparison, or look for a plan that covers more of those services.

What happens if I travel outside my plan's service area?

HMO plans usually do not cover care outside their service area except emergencies. PPO plans cover out-of-network care at a higher copay. If you travel frequently or spend winters in another state, ask about plans that cover out-of-area care, or choose a PPO plan instead of an HMO.

Is there a penalty if I do not choose a Medicare Advantage plan?

No. You can stay on Original Medicare instead. However, if you later decide to switch to Medicare Advantage, you may face a higher premium if you have certain pre-existing conditions, depending on your state. It is worth comparing Original Medicare plus a Part D drug plan against your best Medicare Advantage option before you decide.
