Key Takeaways

  • Medicare Part B covers annual screening mammograms for women age 40 and older
  • Diagnostic mammograms are covered when medically necessary with applicable coinsurance
  • Medicare Advantage plans must cover mammograms at least as well as Original Medicare
  • Preventive screening mammograms are typically free with no deductible or copay
  • 3D mammography (tomosynthesis) is now covered under Medicare

Medicare Coverage for Screening Mammograms

Medicare Part B (Medical Insurance) provides coverage for screening mammograms once every 12 months for women age 40 and older. For women between ages 35-39, Medicare covers one baseline mammogram. The good news for beneficiaries is that when these screenings are received as preventive services, Medicare pays 100% of the Medicare-approved amount.

This means you pay nothing (no deductible or coinsurance) as long as your doctor or healthcare provider accepts assignment. Assignment means they agree to accept the Medicare-approved amount as full payment. Since 2015, Medicare has also covered 3D mammograms (digital breast tomosynthesis) at the same rate as standard 2D mammograms, giving beneficiaries access to this advanced technology that can detect cancer more effectively in women with dense breast tissue.

Diagnostic Mammogram Coverage Under Medicare

Unlike screening mammograms, diagnostic mammograms are performed when a woman has symptoms of breast disease or an abnormal finding on a screening mammogram. Medicare Part B covers diagnostic mammograms when they are medically necessary, but the coverage works differently than for preventive screenings.

For diagnostic mammograms, after you meet the Part B deductible ($240 in 2024), you typically pay 20% of the Medicare-approved amount. This coinsurance applies because diagnostic mammograms are not classified as preventive services. If you receive the diagnostic mammogram in a hospital outpatient setting, you may also have a copayment. It's worth noting that doctors might order diagnostic mammograms more frequently than once a year if medically necessary, and Medicare will cover these additional tests when properly documented as required for your care.

Medicare Advantage Plans and Mammogram Coverage

Medicare Advantage (Part C) plans are required by law to provide at least the same level of coverage as Original Medicare (Parts A and B). This means all Medicare Advantage plans must cover annual screening mammograms for women 40 and older and diagnostic mammograms when medically necessary.

Many Medicare Advantage plans offer additional benefits beyond what Original Medicare provides. Some plans may offer more frequent mammogram screenings or lower out-of-pocket costs for diagnostic mammograms. The specific costs and coverage details vary by plan, so it's important to check with your individual Medicare Advantage provider about their mammogram coverage policies. Some plans may require you to use in-network providers or obtain referrals from primary care physicians before getting mammograms. Review your plan's Evidence of Coverage document or call your plan's customer service line to understand your specific benefits.

Additional Breast Cancer Screenings and Services

Beyond standard mammograms, Medicare covers other breast cancer screening and diagnostic services. If a mammogram reveals suspicious findings, Medicare will cover additional tests like breast ultrasounds and MRIs when deemed medically necessary by your healthcare provider.

For women at high risk of developing breast cancer (with a family history, genetic predisposition, or previous breast cancer diagnosis), Medicare may cover more frequent screenings. Medicare also covers genetic counseling and BRCA gene testing for qualifying beneficiaries. These tests help determine if you have certain gene mutations that increase your risk of breast cancer. Medicare Part B also covers clinical breast exams when performed during a covered preventive visit like the Annual Wellness Visit. Understanding these additional benefits helps ensure you receive comprehensive breast cancer screening services under your Medicare coverage.

Conclusion

Medicare's coverage of mammograms provides essential access to life-saving early detection services for breast cancer. By understanding the differences between screening and diagnostic coverage, beneficiaries can better plan for potential costs and make informed healthcare decisions. Remember that while screening mammograms are fully covered with no out-of-pocket costs, diagnostic mammograms will involve some cost-sharing. Always keep records of your mammogram dates to ensure you maintain the recommended screening schedule, and don't hesitate to discuss any breast health concerns with your healthcare provider. Taking advantage of these covered preventive services is an important part of maintaining your health as you age.
