When billing Medicaid as secondary payer, a Carrier Code for each primary insurance may need to be reported on electronic and paper claims. The Carrier Code reported is used as an identifier for Medicaid to recognize the primary payer. Not all states require the use of a Carrier Code.

Each state Medicaid publishes their own list of carrier codes for primary insurances.
The Carrier Code is reported on the CMS-1500 and 837P electronic claim submission as follows:

On the 837P the Carrier Code value will be reported in:
Loop 2330B NM108 = PI
Loop 2330B NM109 = Carrier Code value
Loop 2430 SVD01 = Carrier Code value
