Medicare Part A (hospital insurance) helps cover the costs associated with any inpatient hospital breast cancer treatment, such as surgery and chemotherapy. Medicare Part B (medical insurance) helps cover the costs of your outpatient care and annual mammograms.

Medicare Part B covers mammograms

Medicare Part B covers mammograms in the following ways:

  • One screening mammogram every 12 months for women age 40 and older
  • One baseline mammogram for women ages 35-39
  • Additional diagnostic mammograms that are considered medically necessary may be covered for women of any age

Screening mammograms are covered in full by Medicare Part B, while women receiving a diagnostic mammogram will typically pay 20 percent of the Medicare-approved amount after meeting the Part B deductible.

The Medicare Part B deductible is $226per year in 2023.

Medicare Part A and Part B cover chemotherapy

Medicare covers chemotherapy and radiation treatment of breast cancer in different ways, depending on whether you are a hospital inpatient or if you receive treatment in an outpatient setting.

  • Medicare Part A provides coverage for chemotherapy treatment received in a hospital as an inpatient.

    You must meet your Part A deductible before Medicare coverage kicks in. The 2023 Medicare Part A deductible is $1,600 per benefit period.

  • Medicare Part B covers chemotherapy treatments that are performed at an outpatient facility, such as a doctor’s office or a freestanding clinic.

    You must meet your Part B deductible before Medicare will cover your chemotherapy costs. As mentioned above, the Part B deductible is $226 per year in 2023. After you meet your Part B deductible, you typically pay 20 percent of the Medicare-approved amount for chemotherapy.

Be sure to ask your doctor how Medicare will cover your chemotherapy treatments so that you have a good understanding of your potential costs.

Medicare Part B helps pay for anti-nausea and oral cancer drugs

Medicare Part B may provide some coverage for certain drugs taken for cancer, such as anti-nausea drugs used for symptoms of chemotherapy.

  • Oral cancer drugs
    Medicare Part B will help pay for oral cancer drugs if the drug is available in injectable form or if it is a prodrug of the injectable drug (it breaks down into the same active ingredient as the injectable drug).

    Medicare Part B will also cover new oral cancer medications as they are developed and become available.

  • Oral anti-nausea drugs
    Medicare Part B helps cover the costs of oral anti-nausea drugs if you take them before, during, or within 48 hours after receiving chemotherapy. Part B will also cover these drugs if they’re used as a replacement for an intravenous anti-nausea drug.

If Medicare Part B covers drugs you use to treat breast cancer or to alleviate nausea related to chemotherapy, you will pay 20 percent of the Medicare-approved amount for the drug.

If you receive prescription drug coverage through a Medicare Part D prescription drug plan or a Medicare Advantage plan, your plan may provide additional coverage for your cancer drugs.

Be sure to check with your plan provider for detailed coverage information.

Medicare Part A and Part B cover breast cancer surgery

Medicare covers many medically necessary surgical procedures. If you have a mastectomy and are admitted for an inpatient hospital stay, Medicare Part A will help cover your hospital costs.

  • If you have surgery to remove a breast affected by cancer (mastectomy), Part B will cover the procedure if performed in an outpatient setting, along with the cost of a post-surgical bra.
  • Part A of Medicare will cover surgically implanted breast prostheses following a mastectomy if performed in an inpatient hospital setting.

As with other covered items and services, your Medicare Part A and Part B deductibles and coinsurance apply.

Medicare Advantage plans cover breast cancer treatments and screenings

Medicare Advantage plans (Medicare Part C) are required to offer all of the same benefits that are covered by Original Medicare, combined into a single plan.

This means that the breast cancer screenings, treatments and drugs listed above are covered by Medicare Advantage plans in the same way that they are covered by Medicare Part A and Part B.

Some Medicare Advantage plans may also offer benefits that are not covered by Original Medicare.

Two out of every three cases of invasive breast cancer occur in women over the age of 55.1 And breast cancer accounts for the second-highest number of cancer-related deaths for U.S. women, behind only lung cancer.2

Don’t let your breast cancer screenings and treatment go without adequate medical attention and insurance coverage.
