An Act amending the act of May 17, 1921 (P.L.682, No.284), known as The Insurance Company Law of 1921, in casualty insurance, further providing for coverage for mammographic examinations and breast imaging.

Added new entities, such as hospital plan corporations and professional health services plan corporations, to the list of plans required to cover mammograms.

Added Li-Fraumeni syndrome, Cowden syndrome, and Bannayan-Riley-Ruvalcaba syndrome (and family history of these) as qualifying risk factors for supplemental breast screening coverage.

Updated the definition of 'diagnostic breast examination' to explicitly include either standard or abbreviated breast magnetic resonance imaging.

Added a new subsection requiring insurers to verify that screening mammography service providers are properly licensed before payment.

Changed the effective date mechanism for policies not requiring federal filing from a flat 60-day delay to a 180-day delay after the effective date.
