The act makes changes to requirements for preventive care coverage by health insurers for breast cancer screening, including: Relocating in statute the high-risk breast cancer screening requirements; Defining and specifying criteria for the use of diagnostic breast examinations and supplemental breast examinations; and Clarifying that, in addition to regular breast cancer screening, diagnostic and supplemental breast examinations that are medically necessary and conducted within nationally recognized screening guidelines do not require cost sharing by the patient.(Note: This summary applies to this bill as enacted.)
