Hi Guest! Great questions. D9612 – therapeutic parenteral drugs, two or more administrations, different medications So, not all medical insurers currently will process “D” codes. You are absolutely correct, “D” codes are HCPCS codes, and medical insurers do process other HCPCS codes, for example E0486 for custom made oral appliances to treat obstructive sleep apnea. So, we do see many medical insurers these days that will process “D” codes when there is not a direct CPT crosscode available, but not all unfortunately. It is certainly worth asking your insurer! As for 99070 – yes we do see insurers deciding to list that code as non-reimbursable for their companies, although it is still a valid CPT code. The “D” code may be your best bet for this case if they won”t accept an unspecified code! As for 21215, that is typically billed in 1 unit on the claim, and the entire fee for the grafting applied to it. Dental insurance coding for bone grafting is a bit different – with medical coding, it is simply split into a code for maxillary (upper jaw) bone grafts (21210) and mandibular bone grafts (21215). Hope this helps!
