October isn’t just about pumpkin spice lattes and Halloween costumes: it’s National Breast Cancer Awareness Month, and for healthcare providers nationwide, that means it’s time to double-check those billing codes, review coverage policies, and make sure patients get preventive care without surprises.
Reality check for 2025: about 1 in 8 women in the U.S. will develop breast cancer in their lifetime, and incidence continues to rise modestly in some age groups. Good news: early detection saves lives—and accurate, up-to-date billing helps patients access screenings while protecting your revenue cycle.
Let’s dive into 2025–2026 essentials: codes, payer policies, real-world examples, and practical workflows to keep your team confident and your claims clean.
2025–2026 updates you need to know (ICD-10, CPT/HCPCS, policy)
ICD-10-CM (effective 10/1 annually):
- Z12.31: Encounter for screening mammogram for malignant neoplasm of breast
- Z12.39: Encounter for other screening for malignant neoplasm of breast
- Z15.01: Genetic susceptibility to malignant neoplasm of breast (e.g., BRCA1/2)
- Z80.3: Family history of malignant neoplasm of breast
CPT/HCPCS for breast imaging:
- 77067: Screening mammography, bilateral (includes CAD)
- 77063: Screening digital breast tomosynthesis (DBT), bilateral—add-on to 77067
- 77065/77066: Diagnostic mammography, unilateral/bilateral
- G0279: Diagnostic DBT, unilateral or bilateral—add-on to 77065/77066
Policy highlights for providers:
- USPSTF final recommendation (2024, current for 2025–2026): Biennial mammography for women ages 40–74 (B grade). Many commercial payers align benefits with USPSTF A/B recommendations.
- Medicare: Annual screening mammogram at 40+ and one baseline between 35–39 with $0 cost-sharing when the provider accepts assignment (see details below).
- 2026 commercial plan change to watch: For plan years beginning in 2026, many group health plans must add first-dollar coverage (no cost-sharing) for additional imaging needed to complete a screening (e.g., diagnostic views, ultrasound, MRI per clinical need) and for patient navigation services related to breast and cervical screening. In 2025, coverage for additional imaging varies by plan—check payer policies.
Regulatory reminder:
- MQSA density notification rule is in effect nationwide. Make sure your patient letters and reporting workflows meet the FDA’s current content and timing requirements.
Medicare coverage (2025–2026): what to bill and what patients pay
- Annual screening mammogram: Women and other eligible beneficiaries aged 40+; $0 cost-sharing if the provider accepts assignment.
- Baseline screening: One between ages 35–39.
- Clinical breast exam: Covered as part of the pelvic and clinical breast exam benefit (G0101) every 24 months, or every 12 months if high risk.
- Diagnostic mammography: Covered when medically necessary; Part B deductible/coinsurance apply.
Tip: Distinguish screening vs. diagnostic at scheduling and registration. Screening = no symptoms, routine preventive. Diagnostic = signs/symptoms or abnormal prior imaging.
Real-world example #1: routine screening (Medicare, 2025)
Patient: 52-year-old, no symptoms.
- CPT: 77067; add 77063 if DBT performed
- ICD-10-CM: Z12.31
- Expected patient cost: $0 for screening when provider accepts assignment
- Documentation: Screening intent, last mammogram date, no symptoms
Diagnostic mammography: components, modifiers, and DBT add-on
When screening shifts to diagnostic:
- Use 77065 (unilateral) or 77066 (bilateral)
- Add G0279 for DBT performed in the diagnostic setting
- Modifiers:
- 26 = professional component
- TC = technical component
- No modifier when billing global service
Real-world example #2: abnormal screen—needs diagnostic
Patient: 45-year-old with abnormal screening result.
- CPT: 77066 (bilateral) or 77065 (unilateral) + G0279 if DBT performed
- ICD-10-CM: Link medical necessity (e.g., abnormal imaging finding)
- Documentation: Reference the abnormal screening, side/extent, and radiologist recommendation
- Coverage: Most payers cover diagnostic studies with medical necessity; Medicare coinsurance applies
The breast ultrasound bonus round
When clinically indicated:
- 76641: Ultrasound, breast, unilateral; complete (includes axilla when performed)
- 76642: Ultrasound, breast, unilateral; limited
Use when medically necessary (e.g., targeted evaluation of a palpable area or follow-up of an abnormality). Verify payer policy for concurrent use with tomosynthesis.
Make reminders do the heavy lifting (and boost MIPS performance)
Simple workflows raise screening rates and quality scores:
- Automate EHR recalls at 12 months from last mammogram
- Close care gaps with batch outreach (text/email/portal nudges)
- Use standing orders for screening-eligible patients
- Track MIPS Measure #112 (women 40–74 with a mammogram within 27 months) to protect incentives
Help patients navigate benefits—especially uninsured/underinsured
- Pre-visit: Share which breast screening services are preventive and typically $0 under Medicare and many commercial plans; clarify when diagnostic coinsurance may apply.
- Documentation: Be explicit—screening vs. diagnostic vs. symptom evaluation—to prevent denials.
- Programs: Direct eligible patients to the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) for free/low-cost screening and navigation. Many areas also offer Medicaid pathways for treatment when diagnosed through NBCCEDP.
Real-world example #3: uninsured patient
Maria qualifies for NBCCEDP.
- Your staff helps initiate enrollment and schedules her screening
- You coordinate with the program provider for imaging and follow-up
- You capture documentation for continuity and later primary care linkage
Result: Maria receives timely screening and navigation; your team strengthens community trust and continuity of care.
Common billing pitfalls (and easy wins)
- Screening vs. diagnostic mix-ups: Build scheduling scripts and order sets that capture clinical intent upfront.
- Missing components/modifiers: For diagnostic mammography, don’t forget G0279 when DBT is performed; apply 26/TC correctly.
- Documentation gaps: Include medical necessity for diagnostic studies and reference prior abnormal imaging when applicable.
- Frequency limits: If a patient insists on services outside coverage intervals, consider ABN workflows as appropriate.
- Density notifications: Ensure your letters and reports meet current MQSA requirements.
Resources that actually help
- CDC NBCCEDP “Find a Program” directory to connect patients with no-cost/low-cost screening and navigation
- Susan G. Komen and Breastcancer.org for multilingual patient education
- CMS resources for preventive service coverage, coding, and claims processing
- USPSTF final recommendation for screening (biennial, ages 40–74)
- Payer trend to watch: In 2026, many group health plans will add first-dollar coverage for additional imaging needed to complete a screening and for patient navigation services; in 2025, confirm plan-by-plan.
Making a real difference
Beyond codes and claims, your billing accuracy removes barriers to early detection. Streamlined workflows = fewer denials, faster payments, happier patients—and better outcomes.
The bottom line
Use 2025-ready codes and workflows now, and prep for 2026 coverage expansions for additional imaging and patient navigation. Get screening intent right at scheduling, code tomosynthesis correctly, and guide uninsured patients to NBCCEDP. That’s how you protect patients and your revenue cycle.
