The proposed bill, titled "An Act relative to breast cancer equity and early detection," aims to enhance coverage for diagnostic examinations related to breast cancer across various health insurance policies in Massachusetts. It introduces new sections to multiple chapters of the General Laws, specifically Chapter 32A, Chapter 118E, Chapter 175, Chapter 176A, Chapter 176B, and Chapter 176G. Each section mandates that any insurance policy providing coverage for screening mammograms must also cover diagnostic examinations for breast cancer on terms that are not less favorable than those for screening mammograms. Additionally, the bill prohibits any increase in patient cost-sharing for these services to ensure equitable access to necessary medical care.

The bill defines diagnostic examinations for breast cancer as medically necessary evaluations to assess abnormalities detected during screening or based on an individual's medical history. It specifies that these examinations may include diagnostic mammography, breast magnetic resonance imaging, or breast ultrasound. The provisions of the act will take effect for all contracts entered into, renewed, or amended one year after the bill's effective date, thereby ensuring that individuals have access to comprehensive breast cancer screening and diagnostic services without increased financial burden.
