Subject: Use of Bone Grafts in Conjunction with Apicoectomies, Extractions and/or Implants
Reviewed: December 4, 2012
Important NoteThis Clinical Policy Bulletin expresses our determination of whether certain services or supplies are medically necessary. We have reached these conclusions based on a review of currently available clinical information including:
Aetna considers this surgical procedure to be dental-in-nature (DIN) oral surgery. Coverage may be available for DIN oral surgery procedures under either medical or dental plans. Necessity and appropriateness will be determined through review of corresponding diagnostics and a rationale if necessary. Need for bone grafts used in conjunction with apicoectomies, extractions and/or implants will be based on a clinical scenario in which normal healing cannot be expected.
Bone grafts have been used in conjunction with endodontic, oral surgery, implants and periodontal procedures for years. Studies have clearly demonstrated the potential to realize significant histological and clinical improvement following regenerative therapy. Studies have also demonstrated that the healing capacity of the body following these procedures is able to regenerate/repair lost hard and soft tissue. The use of bone grafts would not appear to be indicated in every clinical situation, depending on a variety of factors.
The vast majority of surgical sites heal without significant defects. In some situations, however, bone grafting can result in a long-term benefit. Large defects associated with apicoectomy/cyst removal extending outside of the tooth's alveolar space may benefit from bone graft-assisted regeneration. Bone grafts in extraction sockets are not routinely indicated. However, they have been shown to be beneficial in ridge preservation when implant replacement is intended.
There is also increasing evidence that bone grafting after third molar removal may be beneficial in reducing periodontal defects on the distal of second molars in a certain "high-risk" subpopulation (for example, age greater than 26 years and significant existing periodontal defects). Bone grafting may also be beneficial at the time of implant placement when the available width of bone at the site is not adequate.
Bone grafts are indicated only when they are medically necessary for the success of the procedure being performed, or when normal healing cannot be expected to eliminate the bony defect.
Ridge augmentation [code D7950] and sinus lift procedures [code D7951] are used in implant placement when sites are deficient in height or width. These codes are medical-in-nature codes and are reviewed as to medical necessity in their own right.
D7950 – Osseous, osteoperiosteal, or cartilage graft of the mandible or maxilla- autogenous or nonautogenous, by report
D7951 – Sinus augmentation with bone or bone substitutes
D7952 – Sinus augmentation via a vertical approach
D7953 – Bone replacement graft for ridge preservation – per site
D6104 – Bone graft at the time of implant placement
