There is no single "best" Medicare Advantage plan — the right choice depends on your doctors, medications, budget, and how much you travel
Medicare Advantage plans (also called Part C) are sold by private insurance companies and bundle your hospital, doctor, and prescription drug coverage into one plan. Each plan has its own network of doctors, different out-of-pocket costs, and different rules about which medications it covers. A plan that works well for someone in your town might not cover your cardiologist, or might charge more for your blood pressure medication. The "best" plan is the one that matches your specific situation.
The process of finding your plan involves checking three things: whether your doctors are in the plan's network, whether your medications are on the plan's formulary (the list of drugs it covers), and whether the monthly premium and out-of-pocket costs fit your budget. You will need to do this work yourself — Medicare does not rank plans or tell you which is "best" because the answer is different for every person.
Key Takeaways
- Call your current doctors before you enroll to confirm they accept the specific Medicare Advantage plan you are considering, because networks change every year.
- Check the plan's formulary (drug list) on Medicare.gov to see whether your medications are covered and what you will pay for each one.
- Compare the monthly premium, annual deductible, copays for doctor visits, and maximum out-of-pocket limit across the plans available in your area.
- Open enrollment runs from October 15 to December 7 each year, and changes take effect January 1 — you cannot switch plans outside this window except in specific situations.
- Your plan options and network change every year, so you must check your plan's coverage again each fall even if you were happy with it last year.
How to check whether your doctors are in the plan's network
Every Medicare Advantage plan maintains a list of doctors and hospitals it contracts with. A doctor in the network charges the plan's negotiated rate; a doctor outside the network either is not available to you, or costs much more. You cannot assume your current doctor is in the plan just because they were in last year — networks change, and doctors move or stop accepting Medicare Advantage.
Go to Medicare.gov, select "Find Care Providers" under the plan you are considering, and search for each of your doctors by name. Write down whether each one appears. Then call your doctor's office directly and ask: "Are you accepting new Medicare Advantage patients from [plan name]?" This step is essential because the online directory is sometimes out of date. If your main doctor is not in the plan, or if you see multiple specialists, check all of them before you enroll.
If your current doctors are not in a plan you otherwise like, ask whether they accept any other Medicare Advantage plans in your area. Your doctor's office staff can usually tell you which plans they participate in. This conversation often saves you from enrolling in a plan that will force you to change doctors mid-year.
How to check what your medications will cost
Each Medicare Advantage plan publishes a formulary — the official list of medications it covers and what you pay for each one. A drug might be covered by one plan but not another, or covered at different copay amounts. Some plans require you to try a cheaper drug first before they will cover the one your doctor prescribed (called a prior authorization). You need to check this before you enroll.
Go to Medicare.gov, find the plan you are considering, and look for the formulary link. Search for each of your medications by name. The formulary will tell you the copay amount, whether prior authorization is required, and whether the drug is on the plan's preferred or non-preferred tier (preferred drugs cost less). Write down the total you would pay for a month's supply of each medication.
If a medication you need is not covered, or costs much more than you expected, contact the plan directly and ask whether they will make an exception. Some plans will cover a non-formulary drug if your doctor requests it in writing, though this takes time. Do not assume you can switch to a different medication — talk to your doctor first about whether a covered alternative would work for you.
How to compare costs across plans
Medicare Advantage plans charge a monthly premium (what you pay to the insurance company), an annual deductible (what you pay out of pocket before the plan starts paying), copays for each doctor visit or service, and coinsurance (a percentage of the cost you pay after the deductible). They also have a maximum out-of-pocket limit — the most you will pay in a year before the plan covers everything at no cost.
Create a straightforward table with the plans you are considering and list the following for each one:
| Cost Type | Plan A | Plan B | Plan C |
|---|---|---|---|
| Monthly premium | |||
| Annual deductible | |||
| Copay for primary care visit | |||
| Copay for specialist visit | |||
| Maximum out-of-pocket limit |
You can find this information on Medicare.gov for each plan, or call the plan directly and ask. Do not just compare premiums — a plan with a low premium might have high copays that cost you more overall. Think about how often you see doctors and what you typically spend on medications in a year, then estimate your total cost under each plan.
What to consider if you travel or live part of the year in another state
Most Medicare Advantage plans are regional — they only cover care in a specific state or county. If you spend winters in Florida and summers in Maine, or if you travel frequently, a regional plan might leave you without coverage when you are away from home. Some plans offer out-of-network coverage for emergencies, but routine care is not covered.
If you travel, look for a plan that either covers your second home state, or choose a plan with strong out-of-network benefits. You can also ask the plan directly: "If I am in [state] for three months, what coverage do I have?" Some plans have agreements with other insurers in other states. If travel is important to you, this question should be part of your decision.
If you move permanently to another state, you can switch Medicare Advantage plans outside the normal enrollment window. Contact Medicare at 1-800-MEDICARE to report your move and learn what plans are available in your new location.
When open enrollment happens and how to enroll
Medicare's annual open enrollment for Medicare Advantage runs from October 15 to December 7. During this window, you can enroll in a new plan, switch from one plan to another, or drop Medicare Advantage and go back to Original Medicare. Changes take effect on January 1. Outside this window, you cannot change plans unless you have a may have access to life event — moving to a new state, losing other health coverage, or becoming newly may be able to access for Medicaid.
To enroll, go to Medicare.gov, log in with your Medicare account, and select the plan you want. You can also call 1-800-MEDICARE and speak to a representative who can walk you through the process. Some plans also allow you to enroll by phone directly with the insurance company. Enrollment takes about 15 minutes.
Mark October 15 on your calendar each year. Even if you are happy with your current plan, you should review it every fall because networks, formularies, and costs change. A plan that covered your doctor last year might not this year.
Questions to ask your doctor and the insurance plan
Before you enroll, have a conversation with your doctor about the plan you are considering. Ask: "Are you in the network for [plan name]? Will you continue to accept this plan next year? Are there any medications I take that this plan might not cover?" Your doctor's office has seen patients switch plans and can often warn you about problems.
Call the plan's customer service number and ask: "If I need a specialist, do I need a referral from my primary care doctor? What happens if I need care while I am traveling? How do I request prior authorization for a medication?" These questions reveal how straightforward or difficult the plan is to use in real life.
Frequently Asked Questions
Can I switch Medicare Advantage plans in the middle of the year?
No, except in specific situations. You can switch during open enrollment (October 15 to December 7) or if you move to a new state, lose other health coverage, or become newly may be able to access for Medicaid. If you make a mistake during enrollment or your circumstances change, contact Medicare at 1-800-MEDICARE to ask whether you may have access to for a special enrollment period.
What if my doctor leaves the plan's network after I enroll?
Contact the plan when ready and ask about your options. Some plans will let you continue seeing that doctor at the in-network rate for a limited time. If not, you may be able to switch to a different plan outside the normal enrollment window — this is considered a may have access to event. Keep records of when your doctor left the network.
Do all Medicare Advantage plans include prescription drug coverage?
Most do, but not all. Check the plan's summary to confirm it includes Part D (prescription drug coverage). If a plan does not include it, you will need to buy a separate Part D plan, which costs extra. It is usually cheaper to choose a plan that bundles drug coverage.
What if I cannot afford the monthly premium?
Some Medicare Advantage plans have a zero dollar premium — you pay nothing monthly, only copays when you use care. These plans are available in most areas. You can also ask about Extra Help, a federal program that pays premiums and copays for people with limited income. Call 1-800-MEDICARE to learn whether you may have access to.
How do I know if my plan's network is good quality?
Check whether your preferred doctors and hospitals are in the network. Look at the plan's summary to see how many primary care doctors and specialists are available in your area. You can also read online reviews from other patients, though remember that people who are very happy or very unhappy are more likely to post. Call the plan and ask how many patients they serve and how long the average wait time is for a new patient appointment.
