Billing Information Ordering Information

The HCPCS code for ERBITUX is J9055 (injection, cetuximab, 10 mg).

Use the following claim formats when ERBITUX is administered to patients on an outpatient basis and billed to health plans (10 mg=1 billing unit):

  • Physician office: CMS-1500 (paper format) or ASC 837P (electronic format)
  • Hospital outpatient: UB-04 (CMS-1450) (paper format) or ASC 837I (electronic format)

All of the coding information is applicable to outpatient procedures only. Typically, there is no need to further identify ERBITUX when billing with HCPCS code J9055.


The NDCs for ERBITUX, listed in the table below, are often necessary in addition to the appropriate J- or C-code when filing a claim for reimbursement.

100 mg/50 mL, single-use vial
100 mg vial=10 billing units
200 mg/100 mL, single-use vial
200 mg vial=20 billing units
5010 Electronic Transaction Coding
  • For electronic transactions, including 837P and 837I, the NDC is to be preceded with the qualifier N4 and followed immediately by the 11-digit NDC for payers who require it
  • This is typically followed by the NDC unit of measure: UN (units), F2 (international units), GR (gram), or ML (milliliter) of the amount administered

The examples given for the sample NDC 5010 format demonstrate NDC quantity reporting for 1 vial of ERBITUX. The actual amount of drug used can vary based on factors such as patient weight. Currently, reporting NDC quantity varies from payer to payer, so the provider should consult each specific payer to determine the required format.
