Bone grafts and membranes that are performed as adjuncts to a primary procedure that is not a covered service are not eligible for benefits. Requests will be reviewed by dental directors and any adjunctive material related to a non-covered primary service (including bone grafts and use of membranes) may be denied as not a covered benefit.
Submissions for bone grafting performed with other periodontal soft tissue procedures should document the separate clinical necessity for the graft; specifically, bone grafts performed in conjunction with soft tissue grafting procedures are not considered for benefits and may be excluded.
Bone grafting is unlikely to be beneficial for broad horizontal interproximal defects; the policy states that broad horizontal interproximal defects do not respond well to bone graft procedures. Routine placement of bone grafts into extraction sites is also discouraged—routinely placing bone grafts into extraction sites may not be necessary for complete and adequate healing. Additionally, bone graft procedures associated with endodontic therapies or minor periradicular surgery may not be benefitted because such sites typically heal by secondary intention.

Provider Actions and Documentation Requirements
Prior review and general submission requirements
Requests for bone grafting procedures may require prior review by dental directors. Submitting dentists must include all clinical information related to the request: recent, dated radiographic images; a letter of rationale explaining the necessity of the bone graft and whether it is related to another service; a recent patient health history; and a recent dated periodontal chart (less than 12 months old) following ADA reporting guidelines.
- Include recent, dated radiographs (permanent files and properly oriented/ labeled)
- Include letter of medical necessity / rationale
- Include recent patient health history
- Include 6-point periodontal charting (within 12 months)
Required imaging and documentation
Submissions must include current (within 12 months) cone-beam computed tomography (CBCT) when applicable, intraoral/external photos, a clinical narrative and chart notes documenting the defect and treatment plan. Ensure CBCT and photos are dated and labeled; narrative should describe defect morphology (vertical, multi‑walled, narrow defects) and rationale for grafting.
- Current dated CBCT (within 12 months) may be required
- Current dated photos of the surgical site
- Clinical narrative detailing defect type and justification
- Chart notes documenting findings and treatment plan
Denial risk — defect types and non‑covered scenarios
Bone grafting is generally indicated for vertical, multi‑walled, or narrow defects and certain Class II furcation defects. Broad horizontal interproximal defects and routine placement into extraction sites typically do not respond well and may be denied. Bone grafts performed with soft tissue grafting or when the primary procedure is non‑covered are not eligible for benefit.
- Indicated: vertical, multi‑walled, narrow defects; Class II furcations
- Not favored: broad horizontal defects; routine grafting of extraction sites
- Not covered when primary procedure is non‑covered or when performed with soft tissue grafting
Clinical thresholds and biologic material limitations
Documentation must demonstrate a minimum periodontal pocket depth of 5 mm (current, within 12 months) for periodontal indications and include diagnostic‑quality, dated radiographs showing vertical bone defects. Biologic materials used for soft or osseous tissue regeneration may be limited or not covered when used with bone grafts (contract dependent).
- 6‑point periodontal charting showing ≥5 mm pocket depths (within 12 months)
- Diagnostic-quality radiographs demonstrating vertical defects (dated, oriented, labeled)
- Use of biologic materials may be limited per group contract
Provider actions — complete submission to prevent delays
When submitting bone graft requests, include all required materials together to avoid delays or denials. Missing current dated CBCT, photos, or narrative/chart notes are common reasons for inadequate documentation.
- Submit CBCT, photos, narrative, and chart notes together
- Ensure all imaging and charting are current and dated
- Failure to provide complete documentation may result in denial or additional requests for information
Background
Bone grafting is intended to replace missing alveolar bone of the maxilla or mandible resulting from periodontal disease and to treat periodontal or peri‑implant defects. Clinical selection favors defects that are most likely to respond to regenerative techniques—specifically vertical, multi‑walled or narrow defects and certain furcation defects (for example, Class II furcation defects), rather than broad horizontal bone loss.
Appropriate use requires sufficient clinical documentation: diagnostic‑quality, properly oriented and labeled radiographs (including CBCT when requested) demonstrating vertical bone defects and current periodontal charting. The policy requires a 6‑point periodontal chart dated within 12 months showing a minimum pocket depth of 5 mm to support the medical necessity of bone graft procedures.

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.
