N.J. Stat. § 26:2SS-16
A carrier which offers a managed care plan shall provide for an annual audit of its provider network by an independent private auditing firm. The audit shall be at the expense of the carrier and the carrier shall submit the audit findings to the commissioner. The commissioner shall make the results of the audit available on the department's website. If the audit contains a determination that a carrier has failed to maintain an adequate network of providers in accordance with applicable federal or State law, in addition to any other penalties or remedies available under federal or State law, it shall be a violation of this act and the commissioner may initiate such action as the commissioner deems appropriate to ensure compliance with this act and network adequacy laws.
