Summary
Aetna has issued a comprehensive clinical policy bulletin (CPB 0095) for orthognathic surgery that defines medical necessity criteria, documentation requirements, and coverage exclusions. The policy requires precertification before orthognathic surgery and clearly delineates covered skeletal deformities (masticatory dysfunction, airway defects, speech impairment with cleft) versus non-covered cosmetic procedures. Billing teams must implement precertification workflows and ensure orthognathic surgery is approved BEFORE any pre-surgical orthodontic treatment begins.
Action Required
REQUIREMENTS:
- Immediately (upon implementation): Billing and precertification teams must establish a mandatory precertification workflow for ALL orthognathic surgery cases (CPT 21083, 21084, 21085, 21088, 21141, 21142, 21143, 21145, 21146). Route all precertification requests to Aetna's Oral and Maxillofacial Surgery Unit.
- Before any orthognathic surgery claim is processed: Verify that precertification was obtained BEFORE pre-surgical orthodontic treatment was initiated. Deny claims if precertification approval predates orthodontic care start date.
- Update all patient eligibility verification forms and provider scheduling systems to flag orthognathic cases for mandatory precertification before any treatment begins.
- Provide providers with documentation checklist (skeletal deformity study models, pre-orthodontic imaging, detailed functional impairment description) to include with precertification requests.
- Reject and deny any orthognathic surgery claims performed for cosmetic purposes (including isolated mentoplasty/chin surgeries for genial hypoplasia, hypertrophy, or asymmetry).
- Implement billing rules to separate orthodontic treatment costs (pre- and post-surgical) as dental benefits—do NOT process under medical claims.
- Flag and deny any claims for experimental/investigational procedures: condylar positioning devices, low-level laser therapy for post-op management, manual lymphatic drainage, non-biodegradable osteosynthesis, 3D virtual treatment planning (CASNOS), or Kinesio taping.
- CONSEQUENCE: Failure to obtain precertification before orthodontic care or failure to verify precertification will result in claim denial per policy language.
