Hi Guest!

D7260 - oroantral fistula closure
can be crosscoded to:
30580 - repair fistula; oromaxillary

D7295 - harvest of bone for use in autogenous grafting procedure
can be crosscoded to:
21210 - Graft, bone; nasal, maxillary or malar areas (includes obtaining graft)
21215 - Graft, bone; mandible (includes obtaining graft)

The two codes above include obtaining the graft.

Otherwise:

20900 - bone graft any donor area

D7320 - alveoloplasty not in conjunction with extractions - four or more teeth or tooth spaces, per quadrant
can be crosscoded to:
