Hi Michele!

D4277 - free soft tissue graft procedure (including donor site surgery), first tooth or edentulous tooth position in graft
D7950 - osseous, osteoperiosteal, or cartilage graft of the mandible or maxilla - autogenous or nonautogenous, by report


The codes listed above do not have direct crosscodes we are aware of, so you can either bill the "D" code on the medical claim (many insurers these days will process "D" codes when they are medically necessary services), or you can try the CPT code below and include a narrative report describing the procedure:
41899 - Unlisted procedure, dentoalveolar structures


Hope this helps!
