N.J. Stat. Ann. § 45:14B-33

If the third-party payor has reasonable cause to believe that the psychological treatment in question may be neither usual, customary nor reasonable, the third-party payor may request, and compensate reasonably for, an independent review of the psychological treatment by an independent professional review committee. The request shall be made in writing to the treating psychologist. No third-party payor having such reasonable cause shall terminate benefits without following the procedures set forth in section 4 of this act.
