Medicare Preventive Services Covered at No Cost

Routine preventive care can help you catch health concerns early and keep routine care on track. But many beneficiaries are unsure which appointments, screenings, and vaccines Medicare covers without cost sharing. The details often depend on whether the service is classified as preventive, whether you have Original Medicare or a Medicare Advantage plan, and whether your provider accepts Medicare assignment.

Knowing what Medicare covers at no cost matters because cost surprises are one of the most common reasons seniors delay care or skip follow-up appointments entirely. The good news is that most preventive benefits were designed to be accessible. When your provider accepts Medicare assignment, many of these services carry no deductible or coinsurance, which removes a meaningful barrier to staying healthy.

Before scheduling, confirm your Part B status and ask the office how the appointment will be billed, especially if you are being evaluated for a specific concern. The following guide breaks down the services available at no cost. It covers the difference between the two wellness visits, the vaccines and screenings covered under Part B, and practical steps for creating a personal prevention plan you can bring to your doctor.

What Medicare Preventive Services Are Covered at No Cost

Medicare Part B covers a broad range of preventive care and screenings without cost sharing when you use a provider who accepts Medicare assignment. That means you generally do not pay the Part B deductible or coinsurance for an eligible preventive service under the applicable Medicare rules. You can review the basics in this guide to Medicare Part B, especially if you are new to Medicare.

Many covered preventive services have no cost sharing because they are recommended at grade A or B by the U.S. Preventive Services Task Force. Under the Affordable Care Act, these recommendations help determine which preventive services qualifying health coverage must cover without a deductible, copayment, or coinsurance. Medicare’s coverage still depends on the specific service, your eligibility, and how it is billed, so ask your provider whether the appointment is being provided as preventive care.

What does preventive care include?

Preventive care is designed to help you stay healthy and identify potential problems early, before symptoms lead to a diagnosis or more intensive treatment. Under Part B, the category includes several types of care:

• Doctor visits: The one-time Welcome to Medicare preventive visit and the Annual Wellness Visit help establish or update your prevention plan.
• Health screenings: Part B covers screenings for conditions such as cardiovascular disease, certain cancers, diabetes, glaucoma, and depression when Medicare’s eligibility and frequency requirements are met.
• Immunizations: Certain vaccines, including flu, shingles, and COVID-19 vaccines and boosters, may be covered at no cost under Part B when the coverage requirements are satisfied.

Examples of cardiovascular screening include blood pressure, cholesterol, and glucose measurements. Cancer screening benefits can include mammograms, colorectal cancer screening such as a colonoscopy, cervical cancer screening, lung cancer screening for eligible beneficiaries, and prostate-specific antigen testing. Other covered preventive services may include bone mass measurement for qualifying individuals, diabetes screening, glaucoma testing for people at risk, and depression screening. Eligibility, timing, and coverage details vary by service.

The key distinction is whether the care is preventive or diagnostic. Preventive care looks for risks or early signs when you do not have a specific medical complaint. Diagnostic care investigates a known symptom or concern and may be subject to deductible and coinsurance rules. Before your appointment, confirm that the provider accepts assignment and ask how the service will be classified and billed. You can also check the current list of Medicare preventive and screening services for service-specific requirements.

The Welcome to Medicare Visit vs. the Annual Wellness Visit

Medicare gives you two different preventive appointments at important points in your coverage. The Welcome to Medicare visit is a one-time appointment during your first year with Part B. The Annual Wellness Visit is a recurring appointment that helps you and your provider create and update a prevention plan.

They are not interchangeable, and neither appointment is meant to replace every other medical visit you may need. Understanding the timing and purpose of each one can help you schedule the right service and avoid expecting a full physical when the appointment is designed for prevention planning.

What happens during the Welcome to Medicare visit?

This initial appointment is designed to create a baseline after you enter Part B. Your provider may review your medical history, current health concerns, risk factors, and recommended preventive services. Because it is a physical-style visit, it can be a useful opportunity to discuss the screenings and immunizations that fit your age, health history, and eligibility.

Schedule it during your first 12 months of Part B if you have not already done so. Tell the office that you are requesting the Welcome to Medicare preventive visit, rather than assuming any routine appointment will be billed that way.

How does the Annual Wellness Visit differ?

The AWV is a yearly planning appointment. It centers on a health risk assessment and a personal prevention plan, so you can identify screenings, vaccines, and other preventive steps to discuss with your care team. Your provider can also update your medical and family history and review changes since your previous visit.

The AWV is not a head-to-toe physical exam. If you have a new symptom or a specific medical concern, explain that when scheduling. A diagnostic evaluation may be handled separately and may have different cost-sharing rules. For more detail, see this Medicare wellness visit guide.

Both appointments are valuable parts of Medicare Part B preventive care. Ask your provider which visit you are eligible for, confirm that the provider accepts assignment, and clarify whether any additional service will be billed outside the preventive appointment.

Cancer and Cardiovascular Screenings Medicare Covers at No Cost

Screenings are where preventive care can make a meaningful difference. They help your clinician look for early signs of disease before symptoms become obvious. Under Part B, many of these medicare preventive services are covered with no cost sharing when the service is preventive and your provider accepts Medicare assignment. You can review the current details at Medicare.gov’s preventive screening guide.

Cardiovascular disease screenings

Part B covers cardiovascular disease screening that can include blood pressure, cholesterol, and glucose measurements. These checks give your healthcare provider information about risk factors that may not cause noticeable symptoms. Your provider can explain which measurements are appropriate for you and how often they should be performed.

Cancer screenings that support early detection

Medicare covers several cancer screening services, subject to the eligibility and frequency rules that apply to each one. Covered examples include:

• Mammograms: Screening mammograms to check for breast cancer.
• Colorectal cancer screening: Services such as screening colonoscopy, when you meet Medicare’s coverage requirements.
• Cervical cancer screening: Screening services for eligible beneficiaries.
• Lung cancer screening: Screening for people who meet Medicare’s eligibility criteria.
• Prostate cancer screening: Screening that includes the prostate-specific antigen, or PSA, test for eligible men.

Eligibility can depend on factors such as age, risk, medical history, and when you last received a screening. Ask your provider to confirm that the appointment and service are being ordered and billed as preventive before you schedule it.

Other preventive screenings Part B may cover

Part B also covers additional preventive services for people who qualify. These may include bone mass measurement, diabetes screening, glaucoma testing for individuals at higher risk, and depression screening. A screening is intended to look for a condition before you have a related diagnosis or specific complaint. If your clinician is evaluating a known symptom or concern, the visit or test may instead be classified as diagnostic and different cost-sharing rules can apply.

Because coverage requirements vary by service, bring your questions to your provider and verify assignment before the appointment. That simple step helps you use the preventive benefits available through Part B while keeping the focus on early detection and informed follow-up.

Preventive Vaccines Medicare Covers (Flu, Shingles, and More)

Vaccines are an important part of Medicare preventive services, but coverage depends on which part of Medicare pays for the vaccine. Medicare Part B covers certain vaccines at no cost when you receive them from a provider who accepts Medicare assignment. That means the provider accepts Medicare’s approved amount as full payment for the covered service.

Part B-covered vaccines include:

• The seasonal flu shot
• The shingles vaccine
• COVID-19 vaccines and recommended boosters

For these vaccines, ask the provider or pharmacy to confirm that the claim will be submitted under Part B and that the provider accepts assignment. You can also review the current details for flu shots, shingles shots, and COVID-19 vaccines on Medicare.gov.

What about vaccines Medicare Part B does not cover?

Some vaccines are covered through Medicare Part D, which is prescription drug coverage, instead of Part B. This distinction matters because the coverage pathway, participating locations, and potential out-of-pocket costs can differ. A vaccine may be medically appropriate without being a Part B benefit.

Before you schedule a vaccine, ask, “Is this covered under Part B or Part D?” If it falls under Part D, check your prescription drug plan’s coverage. Then ask the pharmacy how the claim will be processed. If you have Medicare Advantage, your plan must cover the same preventive services as Original Medicare, although the process for finding an in-network provider may differ.

It is also helpful to separate preventive vaccination from diagnostic care. A routine vaccine is intended to help prevent illness. If you have questions about which coverage applies, a licensed Medicare advisor can help you understand what to verify before your appointment, so you can make a more informed choice without guessing.

How to Schedule Medicare Preventive Services, Step by Step

A simple scheduling routine can help you use your Medicare preventive services before an important appointment or screening slips through the cracks. Keep your Part B information available, ask how the visit will be billed, and bring a short checklist to each appointment.

1. Confirm that Part B is active. Check your Medicare card, online account, or enrollment records to verify that Medicare Part B is active. Write down your Part B effective date because it determines when you can schedule your one-time Welcome to Medicare preventive visit. If you are unsure which coverage you have, review your Medicare Part B details before calling the provider.
2. Book the Welcome to Medicare visit within your first 12 months of Part B. This one-time preventive visit is available during the first 12 months after your Part B coverage begins. Call your primary care provider and request the Welcome to Medicare preventive visit by name. Ask for an appointment early enough to fit within that 12-month window. You pay nothing when the provider accepts assignment.
3. Schedule an Annual Wellness Visit each year. After the initial Welcome to Medicare visit, reserve time each year for an Annual Wellness Visit. The AWV is a separate preventive appointment that focuses on a health risk assessment, your personal prevention plan, and updates to your medical and family history. It is not a full physical exam. Add a reminder to your calendar and ask your provider when you are eligible for the next visit. You can also read more about the Medicare wellness visit.
4. Ask how each service will be billed. When you schedule a screening, vaccine, or wellness visit, ask the office to confirm that it will be billed as a covered preventive service. Also ask whether the provider accepts Medicare assignment, meaning the provider accepts Medicare’s approved amount. These details matter because a service may have no cost sharing when it is preventive and assignment is accepted, while a diagnostic service or a provider who does not accept assignment may result in charges.
5. Keep a preventive checklist for every appointment. Before you go, list the services you have already received, the ones your provider recommended, and any follow-up dates. Include your Part B effective date, your last wellness visit, vaccines, screenings, and questions about eligibility. Bring the checklist to the appointment and update it afterward. If you want help organizing your coverage questions, you can schedule a Medicare consultation with a licensed Medicare agent.

Why You Might Still Get a Bill for a “Free” Preventive Service

Medicare preventive services are often available without a deductible or coinsurance, but “free” depends on how the visit is classified and how the provider bills Medicare. A charge does not always mean the service was excluded from coverage. It may mean that the appointment included diagnostic care or that the provider does not accept Medicare assignment.

Preventive care and diagnostic care are billed differently

Preventive care is intended to help you stay healthy or identify a condition early, before you have a known symptom or specific concern. Examples may include an eligible screening or a routine prevention-focused visit. Diagnostic care, in contrast, investigates a particular symptom, abnormal result, or medical concern. Once a service is considered diagnostic, Medicare cost-sharing rules may apply, including a deductible or coinsurance.

For example, a screening may begin as preventive care, but the provider may order additional tests because of a symptom or an abnormal finding. Those follow-up services can be billed as diagnostic. This distinction can be confusing, especially when the appointment was scheduled as a screening. Before the visit, ask the office which services are expected to be preventive and which could result in a separate charge. You can also ask what will happen if the provider finds something that requires further testing.

Assignment can affect what you owe

Even when a service is covered, your out-of-pocket cost can depend on whether the provider accepts Medicare assignment. An assigned provider agrees to accept Medicare’s approved amount for a covered service. The Medicare coverage information for preventive screening services explains that eligible services generally have no cost to you when the provider accepts assignment: review Medicare’s preventive screening coverage before your appointment.

If the provider does not accept assignment, the office may charge more than Medicare’s approved amount, subject to Medicare rules. Ask directly, “Do you accept Medicare assignment for this preventive service?” Confirm the answer with the billing office, not only the scheduling desk, and keep the name of the person who provided the information.

What if you have Medicare Advantage?

Medicare Advantage plans must cover the same preventive services as Original Medicare. However, plan networks, provider billing procedures, and authorization requirements can still affect how an appointment is handled. Check your plan materials or call the number on your member ID card before scheduling, particularly if you are seeing an out-of-network provider.

If a bill arrives, do not ignore it. Compare the bill with your Medicare Summary Notice or plan explanation of benefits, then ask the provider to review the billing code and classification. Confirming the preventive purpose of the appointment and the provider’s assignment status in advance is one of the simplest ways to reduce surprises.

Your Printable Medicare Preventive Services Checklist

Use this checklist before your next appointment to organize the preventive care covered through Medicare Part B. Bring it to your provider and ask which items apply to your age, health history, and eligibility. Coverage generally comes with no cost sharing when the service is preventive and your provider accepts Medicare assignment.

• Confirm your Part B coverage: Make sure you have Medicare Part B and choose a provider who accepts assignment, meaning the provider accepts Medicare’s approved amount.
• Schedule your Welcome to Medicare visit: If you have had Part B for less than 12 months, ask about the one-time Welcome to Medicare preventive visit. Medicare covers it once during your first 12 months of Part B when the provider accepts assignment.
• Put your Annual Wellness Visit on the calendar: After the initial visit, schedule an Annual Wellness Visit each year. This appointment updates your health risk assessment and prevention plan. It is not a full physical exam. You can also review the details in this guide to a Medicare wellness visit.
• Ask about cardiovascular screening: Confirm when you should check blood pressure, cholesterol, and glucose. These screenings can help identify cardiovascular and related health risks early.
• Review cancer screenings: Ask whether you are due for a mammogram, colorectal cancer screening such as a colonoscopy, or cervical cancer screening. Check for lung cancer screening if you meet the eligibility criteria, and ask about a prostate-specific antigen (PSA) test.
• Check additional preventive screenings: Depending on your circumstances, ask about bone mass measurement, diabetes screening, glaucoma testing for at-risk individuals, and depression screening.
• Review your vaccines: Ask your provider which Part B vaccines you need, including the annual flu shot, shingles vaccine, and current COVID-19 vaccines or boosters.
• Confirm the billing category: Before the appointment, ask the provider to confirm that each service will be billed as preventive rather than diagnostic. A diagnostic service investigates a specific medical concern and may involve deductible or coinsurance costs.

Keep the completed list with your health records and update it after each visit. If a screening leads to additional testing, ask whether that follow-up is preventive or diagnostic so you understand possible costs before receiving care.

Are preventive services free under Medicare?

Many covered preventive services are available without a deductible or coinsurance when they are provided under Medicare’s preventive coverage rules and your provider accepts assignment. However, you may owe a share of the cost if the visit or test becomes diagnostic, or if the provider does not accept Medicare’s approved amount.

What is the difference between preventive and diagnostic services?

Preventive services are intended to keep you healthy or find a condition before symptoms appear. Diagnostic services investigate a specific symptom, complaint, or known condition.
