This bill amends various chapters of the General Laws related to insurance, specifically focusing on diagnostic and supplemental breast examinations. It introduces a new section in Chapters 27-18, 27-19, 27-20, and 27-41, which defines terms such as "cost-sharing requirements," "diagnostic breast examinations," and "supplemental breast examinations." The bill mandates that group health plans and health insurance issuers providing coverage for these examinations cannot impose any cost-sharing requirements, meaning that patients will not have to pay deductibles, copayments, or coinsurance for these services.

The legislation aims to enhance access to necessary breast health screenings without financial barriers, thereby promoting early detection and treatment of breast cancer. The provisions will take effect on January 1, 2026, ensuring that individuals enrolled in these health plans can receive diagnostic and supplemental breast examinations without incurring additional out-of-pocket expenses.
