Hi m1z!
For the pre-authorization, most medical insurance companies will allow a patient to initial/submit a pre-authorization request if the practice does not do it on behalf of the patient. Unfortunately it is not uncommon for a dental practice to be unfamiliar with working with medical insurers (our software & systems help dental practices with this!). If your dental practice is unable to imitate the pre-authorization for you, you can ask your medical insurer to supply you with a patient's request for pre-authroization. These forms are sometimes available on their website as well!
Typically, in addition to the procedure codes below, they will also ask you for ICD-10 (diagnosis) codes. The diagnosis code(s) used will depend on the condition/symptoms, or in other words, why are the services being rendered! For example, for a shattered tooth, some coding options are:
S02.5XXA - Fracture of tooth (traumatic), initial encounter for closed fracture
S02.5XXB - Fracture of tooth (traumatic), initial encounter for open fracture
G89.11 - Acute pain due to trauma
But, it all depends on the condition, and if it was accidental injury/trauma, there are even codes to describe how it happened! For example, W00.0XXA stands for: Fall on same level due to ice and snow, initial encounter). If you'd like to provide me some additional details about the condition, I'm happy to offer you some coding options.
As for the procedure codes 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)
21215 - Graft, bone; mandible (includes obtaining graft)
**use modifier -52 for reduced services when bone is not obtained from patient
D7951 - sinus augmentation with bone or bone substitutes via a lateral open approach
can be crosscoded to:
21210 - graft, bone; nasal, maxillary, or malar areas
*use -52 modifier for reduced services when bone is not obtained from the patient
D6010 - surgical placement of implant body: endosteal implant
can be cross coded to:
21248 - Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); partial(3 or less)
D7210 - Extraction, erupted tooth requiring removal of bone and/or sectioning of tooth, and including elevation of mucoperiosteal flap if indicated
Extractions actually do not have direct crosscode - 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!
