Each group health insurance policy must contain in substance the following provisions:
(1) a provision that, in the absence of fraud, all statements made by applicants or the policyholder or by an insured person shall be considered representations and not warranties, and that a statement made for the purpose of effecting insurance may not void the insurance or reduce benefits unless contained in a written instrument signed by the policyholder or the insured person, a copy of which has been furnished to the policyholder or to the insured person or the beneficiary of the insured person;
(2) a provision that the insurer will furnish to the policyholder for delivery to each employee or member of the insured group, a statement in summary form of the essential features of the insurance coverage of the employee or member and to whom benefits are payable; if dependents are included in the coverage, only one certificate need be issued for each family unit;
(3) a provision that to the group originally insured may be added from time to time eligible new employees or members or dependents, as the case may be, in accordance with the terms of the policy.
