This bill, if passed, would amend current law to prohibit insurance companies from imposing any cost-sharing requirements for diagnostic and supplemental breast examinations. The bill defines diagnostic breast examinations as medically necessary examinations used to evaluate abnormalities seen or suspected from a screening examination for breast cancer or abnormalities detected by another means of examination. Supplemental breast examinations are defined as medically necessary examinations used to screen for breast cancer when there is no abnormality seen or suspected, based on personal or family medical history or additional factors that may increase the individual's risk of breast cancer. The bill applies to group health plans and individual health insurance coverage. This bill would take effect upon passage.
