The bill proposes amendments to the General Laws concerning "Accident and Sickness Insurance Policies," "Nonprofit Hospital Service Corporations," "Nonprofit Medical Service Corporations," and "Health Maintenance Organizations" to include a new section on diagnostic and supplemental breast examinations. The new sections define "cost-sharing requirements," "diagnostic breast examinations," and "supplemental breast examinations." Diagnostic breast examinations are medically necessary and appropriate examinations used to evaluate abnormalities seen or suspected from a screening examination for breast cancer or detected by other means. Supplemental breast examinations are medically necessary and appropriate examinations used to screen for breast cancer when no abnormality is seen or suspected, based on personal or family medical history, or other factors that may increase the individual's risk of breast cancer.

The bill mandates that group health plans and health insurance issuers offering group or individual health insurance coverage, which provide benefits with respect to screening, supplemental, and diagnostic breast examinations, shall not impose any cost-sharing requirements on the insured individuals. This means that individuals enrolled in such plans or coverage would not be subject to deductibles, coinsurance, copayments, or any other out-of-pocket expenses for these breast examinations. The bill is set to take effect upon passage, and its purpose is to ensure that cost is not a barrier for individuals seeking necessary breast cancer screening and diagnostic procedures.
