N.C. Gen. Stat. § 58-53-100

At the option of the insurer, such plans of benefits set forth in G.S. 58-53-90 and 58-53-95 may be provided under one policy. Instead of providing the plans of benefits set forth in G.S. 58-53-90 and 58-53-95, the insurer may elect to provide a policy of comprehensive medical expense benefits without first dollar coverage. Said policy shall conform to the requirements of G.S. 58-53-95; provided, however, that an insurer electing to provide such a policy shall make available the following deductible options: one hundred dollars ($100.00), five hundred dollars ($500.00), and one thousand dollars ($1,000). Alternatively, such a policy may provide for deductible options equal to the greater of the benefits deductible and the amount specified in the preceding sentence.
