When a cpt code, for example 21147 lefort 1, 3pc, states with bone graft, does dbx or dbm (demineralized bone matrix) constitute with bone graft. I bill for the professional/surgeon in this scenerio. I think that the dbx/dbm is a product that the facility will bill for (hcpcs) but does not constitute application/harvesting of bone graft. I have looked for information regarding this and haven't found anything concrete. Any thoughts, thanks!!!!
