Monitor payer policy activity
Defines clinical appropriateness, required documentation, and coding for bone grafting procedures related to periodontal and peri-implant defects, affecting dental providers and prior authorization reviewers under the plan.
No material clinical or coverage changes in this revision.
Coverage and Medical Necessity Criteria
Medical necessity criteria
Covered when ALL of the following are met (reviewed by dental professional):
see clinical indications 1-2
see clinical indications 3-4 and chunk 2
see clinical indications 5-6 and documentation guidance in chunk 2
see clinical indications 7,10,11
see clinical indication 8
Bone graft procedures are subject to coverage limitations and specific documentation requirements. When the primary procedure is not a covered service, all related adjunctive procedures, including bone grafts and use of membranes, are not a covered benefit. Requests for bone grafting procedures may be reviewed for appropriateness by a dental professional and require submission of complete clinical documentation for benefit determination, including recent, dated radiographic images, a letter of rationale, recent patient health history, and a recent periodontal chart (see documentation requirements).
Bone grafts are not considered for benefits when performed in conjunction with soft tissue grafting procedures. In addition, the use of biologic materials for soft or osseous tissue regeneration may not be benefitted when provided in conjunction with bone grafts, depending on group contract provisions.
Broad horizontal interproximal defects are generally not responsive to bone grafting and therefore may not meet medical necessity for benefit. Similarly, bone graft procedures performed in association with endodontic therapies or minor periradicular surgery may not be benefitted because these situations typically heal by secondary intention and do not require grafting.

| D4266 | Guided tissue regeneration - resorbable barrier, per site |
| D4267 | Guided tissue regeneration - non-resorbable barrier, per site |
| D4286 | Removal of non-resorbable barrier |
| D6103 | Bone graft for repair of peri-implant defect - does not include flap entry and closure |
| D6104 | Bone graft at time of implant placement |
| D7295 | Harvest of bone for use in autogenous grafting procedure |
Prior Authorization, Documentation, and Billing Guidance
Prior Authorization / Clinical Review
Prior authorization / clinical review: Requests for bone grafting procedures may be reviewed for appropriateness by a dental professional. Submitting dentists must include all relevant clinical information to support medical necessity.
- Include recent, dated radiographic images (diagnostic quality, properly oriented, labeled; pretreatment images demonstrating vertical bone defects when applicable).
- Include a letter of rationale explaining necessity of the bone graft and whether it is related to another service.
- Include recent patient health history and current (within 12 months) periodontal charting (6-point) indicating minimum pocket depth of 5mm when applicable.
PROVIDER ACTIONS — Submission and Documentation Requirements
Providers must submit complete documentation to support claims and prior authorization requests. Insufficient documentation may result in denial or delay.
- Recent, dated radiographs (periapical, bitewing, panoramic, or CBCT as appropriate).
- Photos, narrative operative notes, and chart notes as applicable.
- Letter of rationale describing defect type (vertical, multi-walled, narrow defect, class II furcation, etc.) and treatment plan.
Provider action — Non‑covered primary procedure makes adjunctive procedures non‑covered
When the primary (root) procedure is not a covered service, all related adjunctive procedures — including bone grafts and membranes — are not covered even if those adjunctive procedures would otherwise be covered when associated with a covered primary service.
- Adjunctive procedures performed solely in association with a non-covered primary procedure will be denied as not a covered benefit.
Provider action — Exclusions: broad horizontal interproximal defects and endodontic‑associated procedures
Bone grafts performed for broad horizontal interproximal defects or in association with endodontic therapies/minor periradicular surgery are generally not expected to provide benefit and may be denied.
- Broad horizontal interproximal defects are typically not appropriate for bone grafting.
- Bone grafts done in conjunction with endodontic procedures or minor periradicular surgery are unlikely to be covered.
Provider action — Clinical scope, documentation, and contract‑dependent limits
Additional provider notes: bone grafting is generally confined to vertical, multi‑walled or narrow defects, class II furcation defects, and limited to periodontal/peri‑implant defects (coverage may vary by group contract). Biologic materials for soft or osseous tissue regeneration and routine grafting of extraction sites may not be covered depending on contract terms.
- Documentation should include CBCT (when obtained), photos, narrative and chart notes as available.
- Bone graft procedures include post‑operative management for the immediate three months following surgery and any surgical re-entry for three years (group contract dependent).
- Bone grafts performed in conjunction with soft tissue grafting procedures are not considered for benefit.
Definitions and Standards
Background
Bone grafts are used to replace missing alveolar bone of the maxilla or mandible due to periodontal disease and to treat periodontal or peri-implant defects. Clinical indications favor grafting in vertical, multi-walled or narrow defects and certain furcation defects (for example, Class II furcation), where regeneration is more likely to succeed.
Coverage is generally limited to periodontal/peri-implant indications (group contract dependent). The policy emphasizes that documentation must demonstrate the anatomic defect (diagnostic-quality, properly oriented and labeled pretreatment radiographs within 12 months) and current (within 12 months) 6-point periodontal charting showing a minimum pocket depth of 5 mm. Other supporting materials such as CBCT, photos, narrative and chart notes may be requested for benefit determination.
OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
