The Medicare Preventive Benefits You Have Already Paid For

You pay a Part B premium every month. Buried inside it is a list of preventive services that cost you nothing extra, and most people on Medicare use only a fraction of them.

Not because they don't want to. Because nobody hands you the list, the names are confusing, and one of the appointments has a billing quirk that catches people out and puts them off going back.

What follows is the coverage, what's included, what's genuinely free, and where the charges creep in. What you should actually be screened for is a conversation with your doctor, not with an article.

Two Visits People Constantly Confuse

1. The Welcome to Medicare Preventive Visit

A one-time appointment available during your first 12 months on Part B. It reviews your medical history, gets you up to date on screenings and vaccines, and produces a written plan setting out which preventive services you need. Per Medicare, you pay nothing if your provider accepts assignment. Miss the 12-month window and this one doesn't come back.

2. The Yearly Wellness Visit

Available once you've had Part B for longer than 12 months, and then annually. Medicare confirms you pay nothing if the provider accepts assignment, and the Part B deductible doesn't apply. Its purpose is to build and update a personalized prevention plan.

Neither of these is a physical examination. That surprises people, and it's the root of most of the confusion in this area. A wellness visit is a planning conversation: history, risk factors, a schedule of what you're due. If you arrive expecting to be examined and treated, you'll either be disappointed or you'll end up being billed.

What Is Actually Covered

Medicare's preventive and screening services list is long. The main categories:

Source: Medicare.gov preventive and screening services. Eligibility and frequency vary by service and by individual risk factors; the full official guide sets out the specifics for each one.

The Condition That Does All the Work

Almost every "you pay nothing" statement carries the same qualifier: if the provider accepts assignment.

• Accepting assignment means the provider agrees to take the Medicare-approved amount as full payment.
• A provider who doesn't accept assignment can bill you more, and your free preventive service stops being free.
• Confirming it takes one question at the front desk when you book, and it's the single most useful thing in this article.

Details on how assignment affects what you pay are on Medicare's costs page.

Three Billing Traps

1. The Wellness Visit That Becomes a Diagnostic Visit

This is the big one. You go in for your free yearly Wellness visit, and partway through you mention your knee has been hurting. The doctor examines it. That portion is now diagnostic care, which is billable: deductible and coinsurance apply. You get a bill for an appointment you were told was free, and understandably conclude Medicare misled you.

2. Screening That Turns Into a Procedure

A screening colonoscopy is covered as prevention. If a polyp is found and removed during the same procedure, the billing category can change, and cost sharing may apply. Rules here have shifted over recent years, so ask the practice how they'll code it beforehand.

3. Frequency Limits

Many services are covered at set intervals: annually, every two years, every ten years depending on the service and your risk factors. Going earlier than the interval allows means the service may not be covered at all.

The fix for all three is the same and takes thirty seconds: when booking, ask "is this being billed as a preventive service, and does the doctor accept assignment?" If you also want to discuss a new symptom, ask whether that should be a separate appointment. It usually should.

How to Get the Most from the Yearly Wellness Visit

• Bring a current list of every medication and supplement, with doses.
• Bring your family medical history, particularly anything that emerged since you last discussed it.
• Bring the names and contact details of every other doctor you see.
• Ask for the written prevention plan and take it home. It tells you what you're due and when.
• Book any screenings that came out of it before you leave the building.
• Book next year's wellness visit at the same time. The appointment that gets skipped is the one nobody scheduled.

That written plan is the genuinely valuable output. It converts a vague sense that you should probably get some things checked into a dated list, which is a materially different thing.

A Timeline of When Things Become Available

The sequencing trips people up, because two of these have windows rather than being permanently available: For how these windows sit alongside Medicare's broader enrollment calendar, see The Three Medicare Enrollment Periods.

1. Months 1 to 12 on Part B

The Welcome to Medicare visit is available, and only during this window. It's the one benefit on this page with a hard expiry. If you've been on Part B under a year and haven't used it, that's the call to make this week.

2. From Month 13 Onward

The yearly Wellness visit becomes available, and then annually thereafter. Note it's 12 months from your last wellness visit rather than a calendar year, so booking in January one year and December the next creates a gap that can push the second one out of coverage.

3. Throughout, on Their Own Schedules

The screenings and vaccines run on their own frequency rules independent of the visits: some annual, some every two years, some far less often, several dependent on your risk factors rather than a fixed interval.

Which is why the written prevention plan from either visit is worth more than the visit itself. It's the only document that pulls all those separate schedules into one list with your name on it.

What Preventive Coverage Does Not Include

Worth being clear about the boundaries, because assumptions here get expensive:

• Routine physical examinations. Neither Medicare visit is one.
• Most routine dental, vision and hearing care under Original Medicare. Many Medicare Advantage plans include limited versions.
• Treatment. Prevention finds things; treating them falls under normal Part B or Part A cost sharing.
• Long-term custodial care, which sits outside Medicare entirely and is the largest unplanned exposure most retirees carry. Size it with the long-term care calculator.

The Script for Booking

Most of the value here comes down to asking three questions when you phone. Word for word:

• "I'd like to book my yearly Medicare Wellness visit. Is that what you'll be coding it as?" This confirms you and the practice are booking the same appointment, which is not a given.
• "Does the doctor accept Medicare assignment?" One question, and it determines whether the visit is free.
• "I've also got something I want to ask about. Should that be a separate appointment?" The answer is usually yes, and asking upfront turns an unexpected bill into a planned one.

If the practice can't answer the first two, that's worth knowing before you arrive rather than after. And if you're new to Medicare, the same call is the moment to ask whether the Welcome to Medicare visit is still available to you.

Why This Belongs in a Retirement Plan

Healthcare is one of the five Lenses Retirelens plans across, and it's the one where a small amount of attention pays disproportionately.

Preventive services are already paid for. Using them costs you time and nothing else, and the alternative, finding things later, is expensive in both money and options. That makes this one of the few genuinely free improvements available in a retirement plan.

It also interacts with the numbers. How long you plan for affects how much you need, and the longevity range calculator gives you a band rather than a single guess. What healthcare costs across that horizon is what the healthcare cost calculator is for.

It also connects to the other Lenses. Cutting future healthcare costs is Finance work as much as Health work, which is what the Finance Lens overview covers in more depth, and catching problems early instead of managing a crisis later is part of what keeps a Legacy Lens overview intact for the people it is planned for.

Frequently Asked Questions

What preventive services does Medicare cover?
A long list including cancer screenings, cardiovascular and diabetes screenings, bone mass measurement, several vaccines, depression and alcohol misuse screening, glaucoma screening, and the two wellness visits. Medicare.gov publishes the full list with frequency limits.

Do I pay anything for preventive services?
For most of them, nothing, provided the provider accepts assignment. That condition matters, so confirm it when you book.

What is the Welcome to Medicare visit?
A one-time preventive visit available during your first 12 months on Part B. It reviews your history, brings you up to date on screenings and vaccines, and produces a written prevention plan. Miss the window and it isn't available later.

What is the yearly Wellness visit?
An annual appointment available after you've had Part B for 12 months, to build and update a personalized prevention plan. You pay nothing if the provider accepts assignment, and the Part B deductible doesn't apply.

Is the Wellness visit a physical exam?
No. It's a planning conversation about history, risk factors and what you're due. Expecting a physical is the most common reason people come away confused or with an unexpected bill.

Why did I get a bill for a free visit?
Almost always because part of the appointment became diagnostic. Raising a new symptom during a preventive visit shifts that portion into billable care, where the deductible and coinsurance apply.

What does 'accepts assignment' mean?
The provider agrees to accept the Medicare-approved amount as full payment. Providers who don't accept assignment can bill you more, which is how a free preventive service stops being free.

How often can I get these screenings?
It varies by service and by your risk factors: some annually, some every two years, some less often. Going earlier than the interval allows can mean the service isn't covered.

Does Medicare Advantage cover the same preventive services?
Advantage plans must cover everything Original Medicare covers, and many add extras. Network rules apply, so confirm the provider is in network as well as accepting assignment. For the broader comparison beyond preventive care, see Medicare Advantage vs Original Medicare.

Should I have a separate appointment for health concerns?
Usually yes. Keeping the preventive visit and any diagnostic discussion separate is the cleanest way to avoid an unexpected bill, and it gives both conversations more time.

Where can I check what I'm due?
Your Medicare account lists preventive services and when you last used them. Medicare also publishes a printable guide to preventive services covering eligibility for each one.

Already Paid for, Rarely Used

There aren't many things in a retirement plan that improve your position at no cost. This is one of them, and the barrier isn't money or eligibility. It's that nobody ever handed you the list.

So the whole task is two phone calls. Book the wellness visit. Ask whether the provider accepts assignment. Take the written plan home and put the dates in the calendar.

That's the entire intervention, and it's free.

Health is one Lens of five. Project what healthcare costs across your retirement, then check where the other four stand.
