Hi guest!

D6103 - bone graft for repair of peri-implant defect - does not include flap entry and closure

Can be crosscoded to:
21210 - Graft, bone; nasal, maxillary or malar areas (includes obtaining graft)
or
21215 - Graft, bone; mandible (includes obtaining graft)

Also, you will want to use modifier -52 for reduced services if the bone is not obtained from the patient.

As for the ICD-10 code to use, that is going to depend on the patient and their condition - basically, why is the service being performed?

For example, if it is due to atrophy, you may use one of the following codes:

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, for implant failures some options:
M27.61 - Osseointegration failure of dental implant
M27.62 - Post-osseointegration biological failure of dental implant
M27.63 - Post-osseointegration mechanical failure of dental implant
M27.69 - Other endosseous dental implant failure


Hope this helps, have a great day!
