In the absence of a policy provision excluding coverage for otherwise covered individuals who have not individually enrolled with the policyholder and undertaken to pay all or a specified portion of the premium applicable to such individual, a blanket disability policy (but not a tuition refund policy) shall contain, in substance, a provision which provides that the described insurance covers all persons who fall within the categories of covered individuals defined in the policy, and that to the persons originally insured by the policy shall be added automatically all such persons as they come within the class of persons defined in the policy issued to the master policyholder.
