Hi Guest!

Here are the CPT codes for bone grafts:

21210 - graft, bone; nasal, maxillary, or malar areas
or,
21215 - graft, mandibular

**use modifier -52 for reduced services when bone is not obtained from patient


As for CT scan:

70486 - Computed tomography, maxillofacial area; without contrast material

or, if it is a CBCT:
76102 - Radiologic examination, complex motion (ie, hypercycloidal) body section (eg, mastoid polytomography), other than with urography; bilateral


As for implants:
21248 - Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); partial(3or less)
21249 - Reconstruction of mandible or maxilla, endosteal implant (eg, blade, cylinder); complete (4 or more)


exams/office visits:
these are billed in medical as Evaluation & Management (E&M) codes - new patients 99201 through 99205, and established patients as 99211-99215.


For the diagnosis code(s), that all depends on that patient's condition/why the services are being done. For example, if these services are being done due to atrophy, here are some coding options:

K08.21 - Minimal atrophy of the mandible
K08.22 - Moderate atrophy of the mandible
K08.23 - Severe atrophy of the mandible
K08.24 - Minimal atrophy of maxilla
K08.25 - Moderate atrophy of the maxilla
K08.26 - Severe atrophy of the maxilla
