Medicare’s $0 Annual Wellness Visit Is Not a Physical — and a Surprise Bill Can Follow

The appointment itself can cost nothing. But if the conversation turns to a new health problem, you could end up paying for the rest.

You schedule your free Medicare checkup. While you are there, you mention that your knee has been bothering you. Weeks later, a bill shows up for a visit you thought was supposed to be free.

That is not exactly a scam. It is how the billing rules work, and many people do not learn that until they are already in the exam room.

Medicare covers a yearly wellness visit that can cost you $0. Yet a research letter published in the Journal of the American Board of Family Medicine found that fewer than 1 in 4 people in Original Medicare, also known as traditional Medicare, used the benefit during the 2020-2022 period it examined.

So many beneficiaries miss a free service, and some who do use it are surprised by a charge. Here is what the visit actually covers, what it does not, and how to keep it free.

1. What the visit is — and what it is not

The annual wellness visit is a planning session, not a full head-to-toe physical. Medicare.gov says you can get one every 12 months.

You owe nothing as long as your provider accepts assignment, meaning the office agrees to take Medicare’s approved amount as full payment. You also do not have to meet your Part B deductible first.

One important distinction trips people up: Medicare says clearly that this is not a routine physical. The provider may take basic measurements such as blood pressure, height and weight, review your medical and family history, and offer health advice.

That is different from the yearly physical many people remember from working years. The mismatch between what patients expect and what Medicare actually covers is where the confusion begins.

What to do: Treat it like a planning meeting for your health. Expect a discussion, not a full exam.

2. Services included that many people overlook

According to Medicare.gov, your provider will also:

• Review the medicines you are taking.
• Perform a cognitive assessment to look for signs of dementia, including Alzheimer’s disease.
• Screen for substance use risks and refer you for treatment if needed.
• Discuss advance directives, the documents that explain your wishes if you cannot speak for yourself.
• Give you a written list of screenings and vaccines you are due for.

A medication review can be valuable on its own if you take prescriptions from several doctors. If dementia is already affecting someone in your family, it is worth reading about how 1 in 4 Medicare patients with dementia receive risky drugs.

The advance-directive discussion can also save money. The Centers for Medicare & Medicaid Services says it waives your deductible and coinsurance for advance care planning once a year when it is done with the wellness visit. If you have that conversation at a separate appointment, you will owe deductible and coinsurance amounts.

3. How a second bill can appear the same day

This is where a free visit can become a paid one.

If you arrive for your wellness visit and then ask about a sore shoulder or a new rash, the doctor may examine and treat that issue. Once that happens, that portion of the appointment is no longer preventive care. It becomes a regular office visit.

CMS billing guidance allows doctors to bill separately for that service on the same day if the problem is significant, distinct from the wellness visit, and medically necessary. The claim is marked with a billing add-on known as modifier 25. In simple terms: one visit, two charges.

That is a legitimate billing rule, not a trick, and practices do not all handle it the same way. But when it happens, the extra service is not free.

Medicare.gov says that if additional services are provided during the same appointment, you may owe coinsurance and your Part B deductible may apply. The annual deductible is $283 in 2026. After you meet it, you usually pay 20% of the cost.

So if it is early in the year and you have not met your deductible, you could be responsible for the full Medicare-approved amount of that office visit. The front desk probably will not explain that rule in advance.

4. Tests that may cost extra

Medicare.gov says your provider may order other tests during the wellness visit if your health or medical history calls for them. That is allowed. Just do not assume every test ordered that day is covered by the $0 benefit.

The rule is simple: if a test or service falls outside the preventive benefit, you may owe coinsurance and the deductible. And if Medicare does not cover it at all — such as a routine physical, according to Medicare’s own example — the entire bill may be yours.

That is why asking for “my annual physical” can backfire. You may be asking for something Medicare will not pay for.

What to do: When a test or service is ordered, ask two questions. Is this part of my wellness visit? And if not, what will I owe? Some services really are free, and we listed them in “13 Things That Are Free With Medicare.”

5. Welcome to Medicare, the yearly visit, and Medicare Advantage

If you are new to Part B, your first preventive appointment is different. The Welcome to Medicare visit is a one-time checkup available during your first year on Part B.

It reviews your medical history and gets you up to date on screenings and vaccines. It is also free when your provider accepts assignment. It is not a full physical either, and the same caution about extra tests still applies.

Timing matters. Your first yearly wellness visit cannot happen within 12 months of enrolling in Part B or of your Welcome visit. You do not have to take the Welcome visit to qualify, though. Count the months before you make the appointment.

If you have Medicare Advantage, Medicare.gov says those plans must cover everything Original Medicare covers. Still, check whether your doctor is in your plan’s network. Going out of network usually means paying more, if the plan allows the visit at all.

6. What to say when you schedule, and what to do if a bill arrives

Many surprise bills start with confusion at the time of scheduling. Use the right wording:

• Say “Medicare annual wellness visit” when you call, not “physical.”
• Ask whether the office accepts assignment.
• If you want a separate problem addressed, ask whether it will be billed separately. Then decide whether to handle it during the wellness visit or schedule another appointment.

If a bill still arrives, do not pay it automatically. If you have Original Medicare, start with your Medicare Summary Notice, which lists what was billed to Medicare, and compare it with the provider bill. Ask the office whether the charge is for the wellness visit or for a separate service.

If you still believe the bill is wrong and you have Original Medicare, Medicare.gov says to appeal by the date listed on your notice. Circle the disputed charge on a copy, write out why you disagree, and send it to the address shown.

Ask the doctor’s office for any records that support your case. If you have Medicare Advantage, contact your plan and ask how its appeals process works.

The bottom line

Medicare’s yearly wellness visit is one of the program’s better benefits: a free sit-down to review medications, assess memory, and plan screenings. Yet many people with traditional Medicare never use it.

Use it — but know exactly what you are booking. Call it by its proper name, keep new medical issues separate unless you are prepared for a charge, and read every statement that follows. The visit is free. The misunderstanding is not.
