The Right Questions to Ask Before You Switch Medicare Plans

Ask these questions before you change plans during open enrollment or a may have access to life event

Switching Medicare plans is a real choice you can make, but the decision depends on details specific to your health, your doctors, and your prescriptions. Before you switch, you need to know whether your current doctors stay in-network with the new plan, what your out-of-pocket costs will actually be, and whether your medications are covered at the same price. The questions below are the ones that determine whether a switch saves you money or creates problems mid-year.

You can change plans during the annual Medicare Open Enrollment Period (October 15 through December 7 each year) or if you have a may have access to life event like moving, losing employer coverage, or a change in income. Outside those windows, you cannot switch unless your situation qualifies.

Key Takeaways

• Call your current doctors' offices directly to confirm they accept the new plan you are considering, because online directories are often outdated.
• Compare your total out-of-pocket costs for the year — premiums, deductibles, copays, and coinsurance — not just the monthly premium.
• Check whether each of your current medications is on the new plan's formulary and at what tier, because the same drug can cost $15 or $150 depending on the plan.
• Verify the coverage rules for any specialists you see regularly, including whether you need a referral and whether prior authorization is required.
• Ask your current plan what happens to any unused deductible or out-of-pocket costs if you switch mid-year, because you do not carry them over.

Will your doctors stay in-network with the new plan?

This is the question that matters most, and it is also the one most people get wrong. Medicare plan websites publish provider directories, but these directories are frequently outdated — doctors move, retire, or drop plans without the directory being updated for weeks or months. Calling the doctor's office is the only reliable way to know.

When you call, ask: "Do you currently accept [Plan Name] Medicare?" Get the answer directly from the scheduling staff, not from a voicemail or website. If the doctor does accept the plan, ask whether they are accepting new patients and whether they have any restrictions on the types of visits they see (some doctors limit telehealth, for example). Write down the date you called and the name of the person who answered, in case you need to reference it later.

If your doctor does not accept the new plan, ask whether they accept any other Medicare plans you are considering. Some doctors accept Medicare Advantage but not Original Medicare, or vice versa. If your main doctor is not in the new plan's network, you will either need to switch doctors or choose a different plan.

What will you actually pay out of pocket each year?

The monthly premium is only one piece of your costs. You also pay deductibles (the amount you pay before the plan starts sharing costs), copays (a fixed amount per visit), and coinsurance (a percentage of the cost). A plan with a lower premium might have a higher deductible or higher copays, which means you could pay more overall.

To compare plans fairly, add up: the monthly premium times 12, plus the deductible, plus what you expect to pay in copays and coinsurance based on how often you see doctors and what services you use. If you take multiple medications, add the annual cost of those too (see the next section). The total is what the plan actually costs you.

Medicare.gov has a plan comparison tool that shows premiums and deductibles side by side, but you will need to do the copay math yourself based on your own health. If you see a specialist four times a year and the copay is $50, that is $200 a year. If you have physical therapy twice a week for three months, multiply that out. The more detailed you are, the more accurate your comparison will be.

Are your medications covered, and at what cost?

Each Medicare plan has a formulary — a list of medications the plan covers. Not all medications are on every formulary, and the same medication can be in different "tiers" on different plans. A drug on Tier 1 might cost you $10, while the same drug on Tier 3 might cost you $75. Some plans require prior authorization, meaning the doctor has to get permission from the plan before you can fill the prescription.

Go to Medicare.gov and use the plan comparison tool to search for each medication you currently take. Write down the tier and the copay for each one. If a medication is not on the formulary at all, call the plan directly and ask whether there is a similar medication they do cover, or whether you can request an exception. Some plans will cover a non-formulary drug if your doctor writes a letter explaining why you need that specific one.

If you take expensive medications or multiple prescriptions, the difference in drug costs between plans can be hundreds of dollars a year. This is often where people find that the cheapest premium is actually the most expensive plan overall.

What are the rules for specialists and prior authorization?

If you see a cardiologist, rheumatologist, or any other specialist regularly, you need to know whether the new plan requires a referral from your primary care doctor and whether certain treatments or tests need prior authorization. Some plans let you see a specialist without a referral; others require one. Some cover an MRI or physical therapy only if the plan approves it in advance.

Call the new plan's customer service number and ask: "If I need to see a [specialist type], do I need a referral?" and "What services require prior authorization?" Write down the answers. Then call your specialist's office and ask the same questions about the new plan specifically. Specialists' offices deal with prior authorization all the time, and they can tell you whether the new plan is easy to work with or difficult.

If you need regular treatments like dialysis, chemotherapy, or home health care, ask the plan how those are covered and whether there are any limits on the number of visits or treatments per year. Some plans cover these services differently than others.

What happens to your deductible and out-of-pocket costs if you switch mid-year?

If you switch plans in the middle of the year, you do not carry over any of the deductible or out-of-pocket costs you have already paid to your old plan. You start fresh with the new plan's deductible on the day your coverage changes. This means if you have already paid $1,500 toward your old plan's deductible, you will owe the full deductible again on the new plan.

Before you switch, ask your current plan: "How much of my deductible have I met so far this year?" and "How much have I paid toward my out-of-pocket maximum?" Then compare that to the new plan's deductible. If you have already met most of your current deductible and the new plan's deductible is high, switching might cost you more money for the rest of the year, even if the new plan is cheaper overall.

The exception is if you switch during the annual Open Enrollment Period (October 15 through December 7). Your new coverage starts January 1, so you are starting fresh anyway and this is not a concern.

Does the plan cover the services and equipment you use?

Beyond doctor visits and medications, ask about coverage for services you actually use: mental health counseling, physical therapy, hearing aids, eyeglasses, dental work, or durable medical equipment like a wheelchair or oxygen. Medicare covers some of these things, but coverage varies widely by plan. Original Medicare covers some services that Medicare Advantage plans do not, and vice versa.

If you wear hearing aids or need regular dental work, for example, ask the new plan: "What is your coverage for [service]?" Get the specific copay or coinsurance amount. Some Medicare Advantage plans offer dental or vision coverage as an added benefit; others do not cover these at all. If these services matter to your health, the difference in coverage can be a reason to stay with your current plan or switch to a different one.

What is the plan's customer service reputation, and how do you reach them?

Before you switch, call the new plan's customer service line and see how long you wait and whether you can reach a person. Some plans have long wait times or only offer support during business hours. If you need to reach customer service frequently because of a chronic condition or complex medications, a plan with poor customer service will be frustrating to deal with.

You can also check online reviews and ask your doctor's office whether they have feedback about working with the plan. Some plans are known for approving prior authorizations quickly; others are known for denying them and requiring appeals. This information is not official, but it reflects real experiences from people who use the plan.

Frequently Asked Questions

Can I switch plans more than once a year?

No, unless you have a may have access to life event. The annual Open Enrollment Period is October 15 through December 7, and your new plan starts January 1. may have access to events include moving to a new state, losing employer coverage, getting married or divorced, or a significant change in income. If you have a may have access to event, you have 60 days to make a change.

What if I realize the new plan is not working after I switch?

You have a 45-day window after your new plan starts to change your mind and go back to your old plan, or to switch to a different plan. This is called the "disenrollment period." After 45 days, you are locked in until the next Open Enrollment Period unless you have a may have access to event.

Should I switch to save money on my premium if everything else is the same?

Not automatically. A lower premium often means higher copays, a higher deductible, or a smaller network of doctors. Compare your total out-of-pocket costs, not just the premium. If you have already met your current deductible mid-year, switching to a plan with a higher deductible will cost you more money for the rest of the year.

Do I need to tell my current plan I am switching?

No. Your new plan handles the paperwork. Your old coverage ends on December 31 (if you switched during Open Enrollment), and your new coverage starts January 1. You do not need to call your old plan to cancel, but you can if you want confirmation that the switch went through.

What if my doctor is in the new plan's directory but tells me they do not accept it?

This happens because directories are outdated. Ask your doctor's office to help you contact the plan directly to resolve it, or call the plan yourself and report the discrepancy. If the doctor truly does not accept the plan, you will need to either switch doctors or choose a different plan. Do not assume the directory is correct.
