A mammogram is a low-dose X-ray examination of breast tissue used to detect breast cancer before it is clinically palpable, as well as to evaluate a new lump or other abnormality. Screening mammograms are routine studies for asymptomatic women; diagnostic mammograms are targeted studies performed to work up a specific finding. Modern breast imaging is increasingly performed with digital breast tomosynthesis (3D mammography), which acquires multiple slice images of the breast and has been shown to detect more cancers and reduce recall rates. The U.S. Preventive Services Task Force recommends biennial screening mammography for women 40–74; other professional societies (ACS, ACR) recommend earlier and more frequent screening based on individual risk. The study itself takes 10–15 minutes, and results typically return within a few days.
費用に影響する要素
- 2D vs 3D imaging: digital breast tomosynthesis adds $50–$150 to the base charge at most facilities.
- Screening vs diagnostic indication: diagnostic mammograms are billed at higher CPT codes than screening mammograms and are typically subject to plan cost-sharing.
- Site of service: hospital outpatient imaging departments bill a facility fee that dedicated breast imaging centers may not.
- Need for additional views or ultrasound: dense breast tissue and equivocal findings often trigger additional imaging on the same day, each with its own CPT code.
- Radiologist interpretation: sometimes billed as a separate professional fee.
- Computer-aided detection (CAD) software: many facilities add a small CAD charge.
節約方法
- Confirm that your screening mammogram is billed as preventive care under ACA rules — it should have no cost-sharing on most commercial plans.
- If you are under 40 or otherwise not covered by preventive-care rules, request the cash/self-pay price; screening mammograms are routinely available for $50–$150 out of pocket at freestanding imaging centers.
- Ask whether a 2D exam is clinically sufficient; tomosynthesis is valuable for dense breast tissue but is not medically required for all patients.
- Look for local breast health initiatives; many states operate programs offering free or reduced-cost mammograms to uninsured and underinsured women (CDC NBCCEDP program).
- If a diagnostic study is ordered, ask the facility whether a bundled rate is available that includes any additional views.
- If you are insured, confirm that the imaging center and the interpreting radiologist are in-network before the appointment.
保険とカバレッジに関する注意事項
Under the Affordable Care Act, screening mammograms for women 40 and older are covered at no cost-sharing by most commercial plans; Medicare covers annual screening mammograms from age 40 at no cost-sharing under Part B. Under a 2023 update to the federal preventive services guidelines, coverage of diagnostic mammograms at no cost-sharing is mandated in a growing number of states, but is not yet universal across commercial plans. Women with dense breast tissue or elevated personal risk may be eligible for supplemental screening ultrasound or MRI; coverage of these modalities varies by plan and state. Medicaid coverage varies by state.
