How does Medicare Part B handle coverage for preventative screenings like mammograms?

Question

Charles Fletcher · Accepted Answer

Medicare Part B covers preventive screenings like mammograms as part of its focus on early detection and health maintenance, with specific rules on frequency, cost, and eligibility. Here’s how it works:

Screening Mammograms: These are covered for women aged 40 and older to detect breast cancer early, before symptoms appear.
Frequency: Part B fully covers one screening mammogram every 12 months (anytime after 11 months from your last one). If you’re new to Medicare, you also get a baseline mammogram covered between ages 35–39.

Cost: There’s no out-of-pocket cost—no coinsurance, copayment, or Part B deductible—as long as the provider accepts Medicare assignment (agrees to Medicare’s payment rates). This applies to 2D and 3D (tomosynthesis) screenings, though 3D coverage was clarified in updates around 2018 to match evolving standards.

Diagnostic Mammograms: If a screening finds something abnormal or you have symptoms (like a lump), Part B covers diagnostic mammograms to investigate further.
Frequency: No strict limit—covered as medically necessary, which could mean multiple in a year if your doctor orders them.

Cost: After meeting the Part B deductible ($240 in 2025), you pay 20% of the Medicare-approved amount. There’s no cap on how many are covered, but each one triggers that 20% coinsurance unless you have a Medigap plan to offset it.

Key Details: The mammogram must be done at a Medicare-approved facility (like a radiology center or hospital outpatient department). If it’s bundled with other services (e.g., a biopsy), additional costs might apply under Part B’s standard rules. Preventive coverage assumes you’re symptom-free—once it’s diagnostic, it shifts to a treatment framework.

This setup reflects Part B’s broader approach to preventive care: full coverage for annual screenings to catch issues early, with cost-sharing kicking in when it’s about diagnosis or follow-up. It’s a balance between encouraging checkups and managing expenses when care escalates.

Medicare Part B covers many preventive screenings, including mammograms, to help detect issues early. In most cases, screening mammograms are covered at no cost to you as long as your provider accepts Medicare assignment.

Generally, Medicare covers one screening mammogram every 12 months for women age 40 and older. If a diagnostic mammogram is needed (for example, due to symptoms or follow-up), you may be responsible for the Part B deductible and typically 20% coinsurance.

Bill Wheeler · Answer

Mamagrams are covered under preventive care but may be subject to a 20 percent copay. It depends on the circumstances and is referred by your doctor.

Jonathan Potter · Answer

If you just have Medicare and no supplement or no, Medicare advantage program than your mammogram would be no cost to you but if they do have to cut anything out during the procedure, then it would be considered a surgery and you would have to pay your deductible and a percentage after that.

Diagnostic Mammograms: Covered when medically necessary. After you meet your Part B deductible, you pay 20% of the Medicare-approved amount.

A baseline Mammogram is covered once in your lifetime, usually between the ages of 35-39. Screenings are covered once annually.  Diagnostic mammograms can be covered more than once a year if medically neccessary. 

Your doctor may recommend other services like 3-D imaging that Medicare does not cover. This could end up in additional costs for you. Make sure to ask your doctor about the reasons for these recommendations and what Medicare will actually cover.

Barbara Barnes, CMIP® · Answer

Yes, but you always need to have a discussion with your doctor when preventive tests are ordered, to be sure that they are coded for claims payment as ‘preventative’. 

If you’ve had a prior diagnosis of abnormal breast tissue, for instance, future mammograms that are performed to keep an eye on that issue will no longer be ‘preventative’ but rather ‘diagnostic’ in nature. 

The same is true of an A1c test for diabetes. As long as your A1c is normal, future tests to make sure that you haven’t developed diabetes should be coded as ‘preventative’ but as soon as you have a reading that indicates diabetes or even ore-diabetes, future tests will be diagnostic. 

Preventative tests are generally paid at 100% by Original Medicare and Medicare Advantage while diagnostic tests are generally subject to your deductible and paid at 80% with Original Medicare, or subject to the plan benefits and copayments with Medicare Advantage.

It’s much easier to check the codes before the test is done than it is to have them changed afterwards. Busy doctors can easily make errors in this type of order, so asking them before they write the order is a good idea.

How does Medicare Part B cover preventative screenings such as mammograms or colonoscopies? Part B should cover you 100% for those preventative screenings. Now, if they're considered diagnostic, there could be a 20% out-of-pocket cost. But it's always best to double-check with your insurance advisor or the doctor's office to make sure beforehand.

Rich Baker · Answer

If you have medicare from age 30-39, Medicare covers a baseline mammogram at no cost (as long as the doctor or facility accepts medicare assignment). After age 40, medicare covers a screening mammogram at no cost once every 12 months (again at a provider who has accepted medicare assignment). 

Diagnostic mammograms are subject to both the medicare part B Deductible and the 20% coinsurance. This is where supplemental coverage can help with those costs, depending on the type of coverage and the plan in question. Your agent can help you sort through your options.

Bruce Resnick · Answer

Per the CMS Medicare website:

Medicare Part B (Medical Insurance) covers:
A baseline mammogram once in your lifetime (if you’re a woman between 35-39).

Screening mammograms once every 12 months (if you’re a woman 40 or older).

Diagnostic mammograms more frequently than once a year, if medically necessary. 

Your costs in Original Medicare
Screening and baseline mammograms: You pay nothing for the test if your doctor or other health care provider accepts assignment.

Diagnostic mammograms: After you meet the Part B deductible, you pay 20% of the Medicare-approved amount when on original government Part B Medicare. 
If on a Supplement (Medigap) or a Medicare Advantage Plan your cost will probably be less then the 20% for diagnostic mammograms

Part B covers a lot of preventative screenings such that they are not subject to the deductible or coinsurance payments. If the mammogram is a screening, it meets this requirement. If it is diagnostic, the service is covered but subject to the deductible and coinsurance payments. The Medicare app “What’s Covered” is a great resource to quickly identify services that are covered and how deductibles and coinsurance apply.
