Coverage and Medical Necessity Criteria
Medical necessity criteria for orthognathic surgery — Covered when ALL of the following are met
Covered when ALL of the following are met
Overall requirement
Qualifying deformity types
- Anteroposterior discrepancy: Maxillary/mandibular incisor relationship: overjet of 5 mm or more, or a 0 to negative value (norm 2 mm); OR maxillary/mandibular anteroposterior molar relationship discrepancy of 4 mm or more (norm 0 to 1 mm).incisor overjet >=5 mm OR molar AP discrepancy >=4 mm
Measured values represent ~2 or more standard deviations from published norms.
- Vertical discrepancy: Presence of a vertical facial skeletal deformity two or more standard deviations from published norms; OR open bite (no anterior vertical overlap OR unilateral/bilateral posterior open bite >2 mm); OR deep overbite with buccal or lingual soft tissue impingement; OR supra-eruption of a dentoalveolar segment due to lack of occlusion.vertical >=2 SDs OR posterior open bite >2 mm
- Transverse discrepancy: Presence of a transverse skeletal discrepancy two or more standard deviations from published norms; OR total bilateral maxillary palatal cusp to mandibular fossa discrepancy >=4 mm, or unilateral >=3 mm, given normal axial inclination of posterior teeth.transverse >=2 SDs OR bilateral >=4 mm OR unilateral >=3 mm
- Asymmetry: Anteroposterior, transverse, or lateral asymmetries greater than 3 mm with concomitant occlusal asymmetry.>3 mm asymmetry
The following procedures are considered not covered when performed solely to improve appearance in conjunction with orthognathic surgery: rhinoplasty for nose reshaping, osteoplasty for facial bone reductions for cosmetic reasons, genioplasty to improve the appearance of the chin, and rhytidectomy (face-lift). Augmentation to reshape or enhance facial features (for example, implants) performed solely for aesthetic purposes during orthognathic surgery is also considered not medically necessary and is excluded from coverage.
Services that are determined to be not medically necessary (or medically necessary services that are non-covered benefits) are excluded from payment. Providers may not charge the member for such services unless the member has been informed in advance and has agreed in writing to assume financial responsibility.
Orthognathic surgery performed in the absence of significant physical functional impairment is considered cosmetic and not medically necessary. Coverage is intended for surgical correction of dentoskeletal deformities when the deformity causes functional problems that cannot be adequately treated with dental or orthodontic care alone.
Services determined to be not medically necessary are not a guarantee for payment and may be excluded from coverage. Providers should verify benefits and eligibility for the member and obtain any required authorizations before proceeding; if a service is non-covered, the provider must obtain the member’s written agreement to be charged prior to delivering the service.

Prior Authorization, Documentation, and Billing Guidance
Prior authorization required for Medicare Advantage; recommended for Commercial
Prior authorization is required for Medicare Advantage plans and is recommended for Commercial Products; obtain authorization via the payer's online web-based tool for participating providers (see Related Policies).
Preauthorization via web-based tool required
Preauthorization for procedures referenced by this policy must be submitted through the payer's web-based tool for participating providers as described in the related Preauthorization via Web-Based Tool for Procedures policy.
Coverage limited to Phase 3 (surgery) with prior authorization
Only Phase 3 (the surgical procedure) is a covered benefit when prior authorization is obtained; Phases 1 (pre-operative monitoring), 2 (pre-operative records/stabilization), and Phase 4 (post-op after 90 days) are not covered and are the member's financial responsibility.
- Phase 1 — Pre-operative: noncovered (monitoring/work-up).
- Phase 2 — Pre-operative records/stabilization: noncovered (model surgery, tracings, device fabrication).
- Phase 3 — Surgery: covered with prior authorization; includes a 90-day post-operative period in the surgical fee.
- Phase 4 — Post-op after 90 days: noncovered (ongoing monitoring).
Required clinical documentation (films, photos, consultation, prediction tracing)
Submit the following preoperative clinical documentation to determine medical necessity: frontal and profile smiling photos; presurgical frontal and lateral cephalograms; panoramic film; consultation letter with diagnostic/treatment plan; and prediction tracing using the presurgical cephalogram. All required documentation must be completed within six (6) months of submitting the case for review.
- Frontal and profile smiling photographs
- Presurgical frontal and lateral cephalograms
- Panoramic film
- Consultation letter (diagnostic/treatment plan)
- Prediction tracing using presurgical cephalogram
- Documentation must be completed within 6 months of submission
Verify benefits and eligibility via member documents and provider call center
Verify member-specific benefits and eligibility with the provider call center; benefits are determined by the member's subscriber agreement, member certificate, and/or employer agreement which supersede this policy.
Denial risk if prior authorization is not obtained for Medicare Advantage
Failure to obtain required prior authorization for Medicare Advantage plans may result in claim denial; prior authorization is recommended for Commercial Products for participating providers.
Do not bill members for non‑covered or not medically necessary services without written consent
If services are determined to be not medically necessary (or are medically necessary but non-covered benefits), they may not be paid; providers may not bill the member unless the member has been informed and agreed in writing in advance to pay.
- Do not charge members for non-covered or not medically necessary services unless the member provided written advance agreement to pay.
- Refer to participation agreement(s) for applicable provisions.
Clinical Background
Orthognathic surgery corrects abnormalities of the maxilla and/or mandible that may be congenital, developmental, traumatic, or due to systemic or environmental causes. It is undertaken when the severity of a skeletal deformity causes significant functional impairment (for example, problems with occlusion, chewing, swallowing, speech, or pain) and cannot be adequately managed with dental or orthodontic treatment alone. Typical indications include anteroposterior, vertical, and transverse discrepancies and asymmetries; the clinical goal is to restore function through realignment of the jaw(s) and correction of dentoskeletal relationships. Preoperative planning and coordination with dental specialists are required, and the surgical procedure often involves osteotomies of the maxilla and/or mandible to normalize occlusion and improve functional outcomes.
Key Definitions
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.
