Hi Guest! As for the procedure (CPT) codes for the services you listed: 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) or 21215 – Graft, bone; mandible (includes obtaining graft) **use modifier -52 for reduced services when bone is not obtained from patient D4240 – gingival flap procedure, including root planing – four or more contiguous teeth or tooth bounded spaces per quadrant The code listed above does not have direct crosscode 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 use the CPT code below and include a narrative report describing the procedure: 41899 – Unlisted procedure, dentoalveolar structures As for the diagnosis (ICD) code(s) – it all depends on your condition. Based on what you described, here are some possibilities, but i would certainly verify these with your doctor: K12.2 – Cellulitis and abscess of mouth T84.7XXA – Infection and inflammatory reaction due to other internal orthopedic prosthetic devices, implants and grafts, initial encounter K05.211 – Aggressive periodontitis, localized, slight K05.212 – Aggressive periodontitis, localized, moderate K05.213 – Aggressive periodontitis, localized, severe K05.311 – Chronic periodontitis, localized, slight K05.312 – Chronic periodontitis, localized, moderate K05.313 – Chronic periodontitis, localized, severe Hope this helps!
