An Act relative to the diagnosis and treatment of breast cancer

This Massachusetts bill expands health insurance coverage for breast cancer screening and diagnostic services for women. It mandates that insurance plans cover baseline mammograms for women aged 35 to 40 and annual mammograms for those 40 and older, while also providing earlier screenings for younger women with specific risk factors like family history or dense breast tissue. The legislation requires coverage for advanced imaging options, such as ultrasound and MRI, when medically necessary due to abnormalities or high-risk conditions, and ensures these services are free of co-pays, deductibles, or dollar limits.
