Hi Leslie! Based on what you described, here are some possible 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 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 Also, for the procedure coding: D7953 – bone replacement graft for ridge preservation – per site 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 Hope this helps!
