A mammogram is an x-ray test that can detect abnormalities in breast tissue. These tests detect breast cancer, regardless of size. This screening test should occur even if you have no symptoms.

But why is it so important? The answer is that nine out of 10 breast cancer cases can is cured with early detection, and acting as soon as possible is essential.

The US Preventive Services Task Force found that women aged 60 to 69 with regular mammograms had a 33% lower risk of dying from breast cancer. Read more to find out how Medicare covers this benefit.

What Can a Mammogram Detect?

While the most common use of a mammogram is early detection of breast cancer, they can also find other breast-related issues such as:

  • Cysts — A cyst is a fluid-filled sac. The breast absorbs fluid as part of the usual cycle of hormonal breast changes.
  • Fibroadenomas — A fibroadenoma is a smooth, firm breast lump of fibrous and glandular tissue.
  • Radial scar — A Radial scar is an abnormality in the breast tissue shaped like a star.
  • Microcalcifications — Spots of calcium salts that show white dots on a mammogram.
  • Ductal carcinoma in situ (DCIS) — With DCIS, the cells lining the milk ducts have become cancerous, putting you at high risk of invasive breast cancer.
  • Atypical ductal hyperplasia (ADH) — The cells lining the milk ducts are growing oddly.

Does Medicare cover mammograms?

Medicare Part B covers both analog and digital mammogram coverage every 12 months. In some cases, Medicare can cover them more frequently if you’re considered high-risk or your doctor deems it medically necessary.

Some items that can be considered high-risk factors are:

  • Family history of breast cancer
  • Personal history of breast cancer

Suppose you need a mammogram as a diagnostic test if you’ve already paid your annual Medicare Part B deductible. Medicare will pay 80% of the Medicare-approved amount; you can expect to pay the remaining 20% and up to a 15% excess charge.

Additional insurance options can assist with the costs associated with diagnostic mammograms and if you need treatment for cancer or other conditions discovered with a mammogram.

Medicare Advantage Coverage for Mammograms

Medicare Advantage plans are another name for Medicare Part C. These plans roll your Medicare Part A, Part B, and in many cases, Part D coverage into one program. These plans must cover the same benefits as Original Medicare health insurance and can have additional benefits.

Medicare Advantage plans will follow the same preventative screening schedule as Original Medicare. Preventive mammograms will be at no cost. If the mammogram is considered diagnostic, you’ll be required to pay the price outlined by the terms of your plan. Typically it’ll be a fixed, affordable copay.

Medicare Supplement Coverage for Mammograms

Medicare Supplement plans are gap coverage for a portion or all of your Medicare out-of-pocket costs. These Medigap insurance plans are the same no matter which company you enroll with. There are several plans to choose from, and your plan letter will determine your coverage level.

Medicare Supplement insurance will travel with you and cover you at any healthcare provider nationwide that accepts Medicare. In addition, you won’t need a referral to see a specialist.

How often do you get mammograms on Medicare?

Medicare offers 2D and 3D mammograms to female beneficiaries as a preventive health measure for the early detection of breast cancer every 12 months. The tomosynthesis or 3D mammograms are superior to their 2D counterparts.

How are mammogram tests administered?

A mammogram typically lasts 10 to 15 minutes and is performed in a radiology office or as an outpatient in a hospital radiology department. Mammography uses a mammogram machine, which uses low-dose x-rays to produce high-resolution images of breast structures.

Mammography can be analog, producing images printed on silver film or digital, allowing computer processing of the resulting images. Today, mammography is a digital technology, and mammograms exist to detect possible breast cancer.

This screening requires your consent before it’s administered; you are free to accept or refuse it. Now that we understand how a mammogram works, we’ll discuss Medicare and its relationship to mammography.

Mammograms use a machine designed to view breast tissue, and it takes X-rays at lower doses than the X-rays used to examine other body parts, such as the lungs or bones. The mammography camera has two plates that compress or flatten the breast to spread the tissue apart. This spreading of the tissue provides better-quality images and uses less radiation.

Diagnostic Mammogram versus Preventative Mammogram Screening

There are essential differences between types of mammograms.

  1. Screening mammograms are annual preventive exams; doctors may order a diagnostic mammogram if there are signs of breast cancer symptoms.
  2. A diagnostic mammogram is more detailed than a screening mammogram.

Screening mammograms take only 10 to 20 minutes, while diagnostic mammograms may take longer.
