My understanding is that 80300 should only be billed once as it encompasses an unset number of drugs. However, this code is being rejected at my clearinghouse as invalid. I am stumped. 80300 is the only new code I can find, info says it became active on 1/1/15 but it still won't go through. Same with the new code J1071 (testosterone cypionate). I am stumped. Hopefully someone will give us some insight.
