Understanding Medicare Coverage for Mammograms

Medicare is a federal health insurance program that serves people age 65 and older, some younger people with disabilities, and people with end-stage renal disease. Within Medicare's coverage structure, mammograms—X-ray imaging of the breast used to detect cancer—receive specific coverage guidelines that differ based on your age and risk factors.

The Centers for Medicare & Medicaid Services (CMS) covers screening mammograms and diagnostic mammograms under different rules. A screening mammogram is performed when you have no symptoms and the test is meant to look for early signs of cancer. A diagnostic mammogram is performed when you have symptoms like pain, lumps, or discharge, or when a screening mammogram found something that needs further investigation.

Medicare Part B covers screening mammograms at no cost to you—meaning you pay nothing out of pocket for the test itself. This coverage applies once every 12 months for women age 40 and older. For women age 50 to 74, Medicare covers this screening annually. Women under 40 or over 74 may still receive coverage if their doctor refers them for medical reasons.

Understanding these coverage rules matters because knowing what Medicare will pay helps you plan your care and avoid unexpected bills. Many women are unaware that their screening mammograms cost nothing under Part B, and some delay getting mammograms because they assume they will have to pay.

Practical Takeaway: If you have Medicare Part B and are age 40 or older, you may receive one free screening mammogram annually. Diagnostic mammograms (those performed because of symptoms or abnormal findings) also have no cost-sharing under Part B when ordered by your doctor.

What Medicare Part B Covers and What It Doesn't

Medicare Part B is the medical insurance portion of original Medicare that covers doctor visits, outpatient services, and preventive care. When it comes to mammograms, Part B coverage is straightforward but has specific limitations you should understand.

Medicare Part B covers:

• One screening mammogram every 12 months for women age 40 and older
• All screening mammograms for women age 50 to 74 without any age limit
• Diagnostic mammograms when medically necessary, ordered by a physician
• Additional screening mammograms if your doctor documents medical reasons based on your personal or family history of breast cancer
• 3D mammography (tomosynthesis) when deemed medically necessary by your doctor
• Ultrasound of the breast when ordered to evaluate abnormal findings on a mammogram

Medicare Part B does not cover:

• Screening mammograms for women under age 40 without a doctor's referral for specific medical reasons
• Mammograms performed purely for cosmetic or non-medical purposes
• Routine screenings beyond one per 12-month period for standard screening purposes
• Services that are not ordered by a licensed physician or healthcare provider

The distinction between "screening" and "diagnostic" mammograms matters for your out-of-pocket costs. Screening mammograms have zero cost-sharing. Diagnostic mammograms—those performed because you have symptoms or abnormal results—also have no cost-sharing under Part B. However, if you have not met your Part B deductible for the year, you may be responsible for that deductible amount before coverage begins.

In 2024, the Medicare Part B annual deductible is $240. Once you meet this deductible, mammography services are covered with no additional copayment or coinsurance. This means after you pay $240 toward covered services in a calendar year, your mammogram is completely covered with no out-of-pocket cost.

Practical Takeaway: Check whether you have met your Part B deductible for the current calendar year before your mammogram appointment. If you have not met it, you may owe up to $240. After your deductible is met, your mammogram costs you nothing.

How to Receive Your Free Mammogram Through Medicare

Receiving a mammogram covered by Medicare involves several steps. Understanding this process helps you avoid confusion and ensures your visit goes smoothly.

First, you need to have Medicare Part B. Medicare Part B is the medical insurance component of original Medicare. If you have a Medicare Advantage plan (Part C) instead of original Medicare, your mammogram coverage may differ, and you should contact your plan directly for information about their coverage rules.

Second, schedule an appointment with a mammography facility that accepts Medicare. Most hospitals, imaging centers, and radiology clinics accept Medicare for mammograms. When you call to make your appointment, inform the facility that you have Medicare Part B. They will verify your coverage before your visit. You can search for Medicare-participating mammography facilities by using the Centers for Medicare & Medicaid Services provider search tool on Medicare.gov.

Third, bring your Medicare card to your appointment. The facility staff will check your card to confirm your coverage and ask for information about your Part B deductible status. Let them know if you have already met your deductible for the year or if you are unsure.

Fourth, discuss with your doctor whether you need a screening or diagnostic mammogram. If you are age 40 or older and have no symptoms, your doctor can order a screening mammogram. If you have symptoms like breast pain, a lump, or nipple discharge, or if a previous mammogram showed an abnormality, your doctor will order a diagnostic mammogram. Both types are covered at no cost after your deductible is met.

You do not need a referral from your primary care doctor to get a screening mammogram at most facilities, but you do need a doctor's order. Some imaging centers allow you to self-refer for screening, meaning you can call directly to schedule without a doctor's referral, as long as you have a standing doctor's order on file. However, this varies by facility and location.

Fifth, after your mammogram, the radiologist will review the images. The results are typically sent to you and your doctor within a few days. If the results are normal, you will receive a letter or call confirming this. If an abnormality is found, your doctor will contact you to discuss next steps, which may include a diagnostic mammogram, ultrasound, or other imaging.

Practical Takeaway: Call a Medicare-participating mammography facility, confirm they accept your Part B coverage, bring your Medicare card, and ensure your doctor has placed an order for the mammogram. You will receive results within days, typically at no out-of-pocket cost.

Special Situations: Age Groups and Risk Factors

Medicare mammogram coverage has nuanced rules based on your age and individual risk factors. Understanding where you fit in these categories helps clarify what coverage is available to you.

For women ages 40 to 49, Medicare Part B covers one screening mammogram every 12 months. However, this coverage is at the discretion of your doctor. Your healthcare provider must determine that a screening mammogram is medically reasonable and necessary. This typically means your doctor will order a screening mammogram if you have risk factors for breast cancer, such as a family history of breast cancer, genetic mutations like BRCA1 or BRCA2, or a personal history of atypical breast findings.

For women ages 50 to 74, Medicare Part B provides coverage for one screening mammogram annually without any documented risk factors required. This is straightforward coverage—you and your doctor can decide together that you want a screening mammogram, and Medicare will cover it once per 12 months.

For women age 75 and older, Medicare does not have a standard screening mammogram benefit. However, if your doctor orders a diagnostic mammogram for you because of symptoms or abnormal findings, Medicare will cover it. Some women over 75 also receive coverage if their doctor documents specific medical reasons for screening based on their health status or risk factors.

Women with a personal or family history of breast cancer may be entitled to more frequent mammograms. If you have such a history, discuss this with your doctor. They can document the medical reasons and order additional mammograms beyond the standard once-per-year screening. Medicare will cover these additional mammograms
