This bill amends various chapters of the General Laws related to insurance policies, specifically focusing on diagnostic and supplemental breast examinations. It introduces new sections in each chapter that define 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, ensuring that individuals enrolled in such plans can access necessary breast health services without financial barriers.

The provisions outlined in the bill will take effect on January 1, 2027, allowing time for insurance providers to adjust their policies accordingly.
