codes for bone grafting of the femoral and tibial tunnels with allograft.

Dr. did a joint debridement & partial synovectomy for failed ACL reconstruction, and bone graft of the tunnels with allograft bone, and hardware removal- deep. There was therefore no harvesting of bone. I don't know if there are codes for bone grafting of the femoral and tibial tunnels with allograft.

Any help would be appeciated
