Hi Guest!

D7950 - osseous, osteoperiosteal, or cartilage graft of the mandible or maxilla - autogenous or nonautogenous, by report
Can be cross coded to:
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


As for the diagnosis code(s), this will depend on the reason/condition the patient is receiving the services. For example, is the patient has atrophy, here are some diagnosis coding options:

K08.21 - Minimal atrophy of the mandible
K08.22 - Moderate atrophy of the mandible
K08.23 - Severe atrophy of the mandible
K08.24 - Minimal atrophy of maxilla
K08.25 - Moderate atrophy of the maxilla
K08.26 - Severe atrophy of the maxilla

Or, if you have additional information on the patient's condition, let me know and I can offer you some coding options.

Hope this helps!
