Ohio Revised Code Title XXXIX. Insurance § 3917.03

(A) The premium for the insurance shall be paid either from the funds contributed by the employer, union, association, or other person to whom the policy has been issued, or from funds contributed by the covered persons, or from both. Except as provided in division (B) of this section, a policy on which no part of the premium for the dependent's coverage is derived from funds contributed by the covered persons shall insure the dependents of all eligible employees or members, or a class or classes of dependents.

(B) A life insurer may exclude or limit the coverage on any dependent as to whom evidence of individual insurability is not satisfactory to the insurer.
