Contraception Injection Admin code for Coventry of DE

I am billing 96372 as admin for contraception like Depo, but only Coventry of DE is denying this code for missing primary code even though J1055 is billed. I talked with sveral reps and they are saying that per Coventry of DE fee schedule 96372 is not admin code for J1055 and vice versa. Can anyone help me to find a admin code which Coventry of DE accepts.
