N.J. Stat. § 17:48A-7c
Every group and individual contract providing medical service benefits delivered, issued, executed or renewed in this State, or approved for issuance or renewal in this State by the Commissioner of Insurance on or after the effective date of this amendatory and supplementary act, shall offer coverage for maternity care without regard to marital status to subscribers or other persons covered thereunder for expenses incurred in pregnancy and childbirth. The maternity benefits shall be provided to the same extent as the benefits are provided in the contract for any other covered illness. If a fixed amount is specified in the contract for surgery, the fixed amount for a pregnancy-related surgical procedure shall be commensurate with the fixed amount payable for a surgical procedure of comparable difficulty and severity.
