Box 24  The 6 service lines in section 24 have been divided horizontally to accommodate submission of both the NPI number and BCBSNC identifier during the NPI transition, and to accommodate the submission of supplemental information to support the billed service. The top area of the six service lines is shaded and is the location for reporting supplemental information. It is not intended to allow the billing of 12 lines of service. Use of the supplemental information fields should be limited to the reporting of NDC codes. If reporting NDC codes, report the NDC qualifier “N4” in supplemental field 24a followed by the NDC code and unit information (UN = unit; GR = Gram; ML = Milliliter; F2 = International Unit).
