Billing J1050 to BCN

I need some help. Pt came into office, we provided injection and according to BCN "the claim has to show the correct national drug code, unit of measure and quantity for the item. I have called provider services and have gone on their website to see an example. If somebody could provide me with an example, I would appreciate it. For some reason, they're the only insurance that I'm having issues with. The other insurance companies have paid our claims.

Thank you!!!!!
