Hi RTilly! Thanks for the kind words! Great questions. The CPT code to use for sinus lifts: 21210 – Graft, bone; nasal, maxillary or malar areas (includes obtaining graft) **use modifier -52 for reduced services when bone is not obtained from patient The pre-authorization request is typically submitted by the provider instead of the patient, as they will need information like your NPI and Tax ID to process this request. While some insurers may require that the patient”s PCP initiates these types of requests to out of network providers, most medical insurers will accept the request from the dentist. Hope this helps!
