N.J. Stat. § 17B:27-30
Benefits of group health insurance, except benefits for loss of time on account of disability, may be provided for one or more members of the families or one or more dependents of persons who may be insured under a group policy referred to in section 17B:27-27, 17B:27-28 or 17B:27-29. Any group health insurance policy which contains provisions for the payment by the insurer of benefits for expenses incurred on account of hospital, nursing, medical, or surgical services for members of the family or dependents of a person in the insured group must, subject to payment of the appropriate premium, permit such family members or dependents to have coverage continued for at least 180 days after the death of the person in the insured group, subject to the policy provision as to termination of coverage with respect to family members or dependents for reasons other than the death of the person in the insured group.
All group health insurance policies which provide coverage for a family member or dependent of an insured on an expense incurred basis shall also provide that the benefits applicable for children shall be payable with respect to a newly-born child of that insured from the moment of birth. The coverage for newly-born children shall consist of coverage of injury or sickness including the necessary care and treatment of medically diagnosed congenital defects and birth abnormalities. If payment of a specific premium is required to provide coverage for a child, the policy may require that notification of birth of a newly-born child and payment of the required premium must be furnished to the insurer within 60days after the date of birth in order to have the coverage continue beyond such 60-day period.
All group health insurance policies which provide coverage on an expense incurred basis for the insured but do not provide coverage for a family member or dependent of the insured on an expense incurred basis, except such group policies as provide no dependent coverage whatsoever for the insured's class, shall nevertheless provide for coverage of newborn children of the insured which shall commence with the moment of birth of each child and shall consist of coverage of injury or sickness including the necessary care and treatment of medically diagnosed congenital defects and birth abnormalities, provided application and payment of the required premium are made to the insurer to include in said policy coverage for a newly-born child as described in the previous paragraph of this section within 60 days from the date of birth of a newborn child.
A policy under which coverage of a dependent of an employee or other member of the insured group terminates at a specified age shall, with respect to an unmarried child covered by the policy prior to the attainment of age 19, who is incapable of self-sustaining employment by reason of intellectual disability or physical handicap and who became so incapable prior to attainment of age 19 and who is chiefly dependent upon such employee or member for support and maintenance, not so terminate while the insurance of the employee or member remains in force and the dependent remains in such condition, if the insured employee or member has within 31 days of such dependent's attainment of the termination age submitted proof of such dependent's incapacity as described herein. The foregoing provision of this paragraph shall not require an insurer to insure a dependent who is a child with an intellectual disability or physical handicap of an employee or other member of the insured group where such dependent does not satisfy the conditions of the group policy as to any requirements for evidence of insurability or other provisions as may be stated in the group policy required for coverage thereunder to take effect. In any such case the terms of the policy shall apply with regard to the coverage or exclusion from coverage of such dependent.
