A mammogram is the best way to find breast cancer for most women of screening age.1 Original Medicare Part B (Medical Insurance) covers certain preventive services, including mammograms, but there are rules to know before scheduling a mammography.

What types of mammograms will Medicare cover?

There are 3 types of mammograms, and Part B covers them all:2

Baseline mammogram

A baseline mammogram is your first mammogram. It’s used to detect early signs of breast cancer and will be used as a comparison for future mammograms.

Screening mammogram

Screening mammograms are preventive exams to check for new signs of breast cancer. They’re typically performed once a year for women 40 and older with no symptoms or signs of breast cancer and considered at average risk for breast cancer.

Diagnostic mammogram

A diagnostic mammogram is used to look more closely at an abnormality in the breast tissue, such as a lump or a tumor. An x-ray picture of the breast will be taken to check for breast cancer. Diagnostic mammograms can also be used to follow up on a potential risk found during a screening mammogram.

How often does Medicare cover mammograms?

Medicare covers a baseline mammogram once in a woman’s lifetime between ages 35-39. Screening mammograms are covered once every 12 months for women 40 and older. If you need a diagnostic mammogram, Medicare will cover as many as you need if they’re deemed medically necessary.2

At what age does Medicare stop paying for mammograms?

There’s no cut-off age for Medicare coverage and mammograms. If you're enrolled in Original Medicare, Part B will pay for an annual screening mammogram and diagnostic mammograms if medically necessary.

Cost of mammograms with Medicare

Part B covers baseline and annual screening mammograms at 100% of the Medicare-approved amount if your doctor or health care provider accepts assignment. That means you pay $0 (no deductible or coinsurance) for one baseline mammogram between ages 35-39 and one screening mammogram each calendar year for women 40 and older.2

Diagnostic mammograms are covered at 80% of the Medicare-approved amount if you receive the service from a participating provider. That means you pay a 20% coinsurance after you meet your Part B deductible ($174.70 in 2024). What you pay out-of-pocket can depend on how much your doctor charges and other insurance you may have.2

Note: A Medicare Advantage (Part C) plan may help cover some of the costs of mammograms, such as deductibles and coinsurance.
