Every insurer or organization for dental care which pays claims on the basis of fees for medical or dental care which are “usual and customary” shall submit to the Commissioner a complete description of the method it uses to determine those fees. Except as otherwise provided in NRS 239.0115, this information must be kept confidential by the Commissioner. The fees determined by the insurer or organization to be the usual and customary fees for that care are subject to the approval of the Commissioner as being the usual and customary fees in that locality. The provisions of this subsection apply to medical or dental care provided to a claimant under any contract of insurance.
