Reversing a decision made late last year, health insurer Cigna said it will now cover breast screening exams performed with digital breast tomosynthesis (DBT).
Cigna had announced in November 2015 that it would only pay for DBT exams performed for diagnostic purposes, a policy decision it said was based on guidance from the U.S. Preventive Services Task Force (USPSTF). In April 2015, the USPSTF had published draft guidelines that concluded there was insufficient evidence to determine that DBT was clinically superior to traditional mammography for breast cancer screening.
However, Cigna said it elected to change the policy due to guidance earlier this month from the National Comprehensive Cancer Network, which recommended that physicians consider DBT exams as an option for patients' annual breast cancer screening. Cigna's new coverage policy applies to DBT services provided on or after August 23.











![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&fit=crop&h=112&q=70&w=112)
