This bill amends various chapters of the General Laws related to insurance policies, specifically focusing on diagnostic and supplemental breast examinations. It introduces a new section in each chapter, defining 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, which includes deductibles, coinsurance, or copayments.

The provisions of this bill will take effect on January 1, 2026, ensuring that individuals enrolled in health plans will have access to necessary breast examinations without incurring additional out-of-pocket expenses.
