Hi Guest! D7550 – partial ostectomy/sequestrectomy for removal of non-vital bone can be crosscoded to one of the following: 21025 – excision of bone, mandible 21026 – excision of facial bone(s) 41830 – alveolectomy incl. curettage As for the diagnosis code(s) – that depends on the patient”s condition/sympstoms. If you could reply to me with some detail about why the patient is receiving the service, I”m happy to provide you with some coding options.
