Bone grafting CPT codes

21210 - Graft, bone; nasal, maxillary or malar areas (includes obtaining graft)

21215 - Graft, bone; mandible (includes obtaining graft)

**use modifier -52 for reduced services when bone is not obtained from patient

So, for the bone graft codes 21210 & 21215, if bone was not harvested from the patient, you'll want to use modifier 52 for reduced services.
Also for 21210 & 21215, if they were performed on the same date of service, you'll want to add modifier 51 on the lower priced of the two, to indicate multiple surgeries/procedure on the same date of service.

Also, if 99203 is billed on the same date as the 21210 & 21215, you'll want to add modifier 25 to indicate it is a separately identifiable E&M service performed on the same date as the procedure(s).
