Hi Guest!

D7960 - frenulectomy
can be crosscoded to:
41115 - Excision of lingual frenum (frenectomy)
40819 - Excision of frenum, labial or buccal (frenumectomy, frenulectomy, frenectomy)

D4263 - bone replacement graft - first site in quadrant
can be crosscoded to:
21210 - graft, bone; nasal, maxillary, or malar areas
21215 - graft, mandibular
**use modifier -52 for reduced services when bone is not obtained from patient

D4321 - provisional splinting - extracoronal

The code listed above does not have a 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


Hope this helps!
