October is Breast Cancer Awareness Month, and Florida seniors may be overlooking an important Medicare benefit: routine screening mammograms can be covered at no out-of-pocket cost.
But there is an important distinction many Medicare beneficiaries don't realize.
While Medicare Part B covers eligible preventive mammograms without a deductible or coinsurance, additional testing to investigate a potential problem may involve out-of-pocket expenses.
Understanding the difference between a screening mammogram and a diagnostic mammogram can help Florida seniors make informed decisions about their healthcare.
With Breast Cancer Awareness Month activities taking place throughout Tampa Bay and Florida's Gulf Coast, October is an excellent opportunity to review your screening history and understand what Medicare covers.
Tampa Bay Communities Are Recognizing Breast Cancer Awareness Month
Breast Cancer Awareness Month brings renewed attention to screening, early detection, and access to treatment.
The City of Tampa recently listed the upcoming Fight Wright Against Breast Cancer Festival, scheduled for Saturday, October 24, 2026.
The community event will take place at Perry Harvey Sr. Park in downtown Tampa from 10 AM to 2 PM.
The event includes a breast cancer awareness walk, run, and festival activities. Attendance is free, and preregistration is not required. City of Tampa
For seniors in Tampa, Apollo Beach, Riverview, Brandon, Bradenton, Sarasota, and surrounding Gulf Coast communities, events like this highlight the importance of staying informed about preventive healthcare.
But understanding the Medicare benefits available for breast cancer screening is equally important.
1. Medicare Part B Covers Routine Screening Mammograms
Under Original Medicare, Part B covers routine screening mammograms for eligible women age 40 and older.
Medicare generally covers one screening mammogram every 12 months.
When the healthcare provider accepts Medicare assignment, beneficiaries pay:
$0 deductible
$0 coinsurance
$0 copayment for the covered screening
This means an eligible beneficiary can receive a routine screening mammogram without paying out of pocket for the test.
Medicare also covers one baseline mammogram for eligible women between ages 35 and 39.
These benefits are established under Medicare Part B and do not require someone to purchase an additional insurance policy. Medicare
2. Screening Mammograms and Diagnostic Mammograms Are Different
This is one of the most important distinctions to understand.
A screening mammogram is performed when someone does not have symptoms of breast cancer. Its purpose is to look for abnormalities that may require further evaluation.
A diagnostic mammogram is performed when a healthcare professional needs to investigate a specific concern.
Examples include:
A breast lump
Unusual breast pain
Nipple discharge
An abnormal screening mammogram
Another finding requiring closer examination
Both types of mammograms can be covered by Medicare.
However, they have different cost-sharing requirements.
3. Diagnostic Mammograms May Have Out-of-Pocket Costs
Under Original Medicare, diagnostic mammograms are covered when medically necessary.
After meeting the Part B deductible, beneficiaries generally pay 20% of the Medicare-approved amount.
This means someone who receives a routine screening mammogram at no cost could still owe money if their physician orders additional diagnostic imaging.
For example, imagine a Florida Medicare beneficiary receives a routine screening mammogram.
The screening identifies an area that requires closer evaluation.
Her doctor orders a diagnostic mammogram and possibly a breast ultrasound.
Although the initial screening may cost nothing, the follow-up services may involve deductible or coinsurance expenses.
Medicare covers medically necessary breast ultrasounds when ordered by an appropriate healthcare provider, but additional cost-sharing may apply. Medicare
An abnormal screening result does not automatically mean someone has cancer.
Additional imaging is often used to determine whether a finding requires further investigation.
4. Does Medicare Cover 3D Mammograms?
Many healthcare facilities now offer 3D mammography, also known as digital breast tomosynthesis.
This technology creates multiple images of breast tissue to help radiologists evaluate potential abnormalities.
Medicare covers qualifying 3D mammography services when applicable coverage and billing requirements are met.
However, whether a particular appointment is considered preventive screening or diagnostic imaging affects the potential cost.
Before scheduling, ask the imaging center whether the appointment will be billed as a screening or diagnostic mammogram.
Also confirm whether the facility accepts Medicare assignment or participates in your Medicare Advantage plan.
5. What About Medicare Advantage Plans?
Medicare Advantage plans must cover Medicare-covered preventive services, including eligible screening mammograms.
However, Medicare Advantage plans may have provider network requirements and different cost-sharing arrangements for diagnostic services.
For example, a beneficiary may receive a qualifying preventive screening without cost-sharing when the plan's requirements are satisfied.
But if additional diagnostic imaging becomes necessary, the plan may apply copayments or coinsurance.
Before scheduling, beneficiaries should verify that the imaging facility participates in their plan, whether referrals or authorization are required, and what their expected costs may be.
Never assume every imaging service is free simply because the original appointment was preventive.
6. How Often Should Older Women Receive Mammograms?
Medicare's coverage frequency and medical screening recommendations are not exactly the same thing.
Medicare allows eligible women age 40 and older to receive a covered screening mammogram once every 12 months.
However, the U.S. Preventive Services Task Force recommends screening mammograms every two years for women ages 40 through 74 who are at average risk.
For women age 75 and older, the Task Force states that current evidence is insufficient to determine the overall balance of benefits and harms of routine screening.
That does not mean Medicare stops covering mammograms at age 75.
Instead, older women should discuss their personal health, medical history, risk factors, and preferences with their healthcare providers to determine whether continued screening is appropriate. USPSTF
7. Florida Offers Additional Breast Cancer Screening Resources
The Florida Department of Health operates the Breast and Cervical Cancer Early Detection Program.
This program provides free or low-cost screening services for eligible women who meet requirements involving age, income, insurance status, and Florida residency.
The program primarily helps qualifying women who have limited or no insurance coverage.
It is not a replacement for Medicare benefits, but it can be an important resource for eligible family members who are not covered by Medicare.
Florida residents can contact local health departments for eligibility information.
For example, the Florida Department of Health lists local program contacts for Hillsborough, Pinellas, Pasco, Sarasota, and surrounding counties. Florida Department of Health
8. What Florida Seniors Should Ask Before Scheduling
Before your next mammogram, consider asking your healthcare provider or imaging center:
Is this appointment considered preventive screening or diagnostic testing?
Does my Medicare coverage pay the full cost of the procedure?
Does the imaging center accept Medicare assignment or participate in my plan?
If additional imaging is necessary, what could I owe?
Based on my age and medical history, how often should I be screened?
These questions can help you better understand your coverage while making informed healthcare decisions.
