Notwithstanding any other provisions in this Title to the contrary, no group policy of accident, health or hospitalization insurance, or of any group combination of these coverages, shall be issued by any insurer doing business in this state which by the terms of such policy group contract excludes or reduces the payment of benefits to or on behalf of an insured by reason of the fact that benefits have been paid under any other individually underwritten contract or plan of insurance for the same claim determination period. Any group policy provision in violation of this Section shall be invalid.
