Orthognathic Surgery - Medicare Advantage

Covers orthognathic surgery (e.g., LeFort I/III, mandibular/mentum osteotomies with fixation, bone grafting and perioperative splinting) to correct severe skeletal/facial deformities and restore form and function. Applicable to patients with congenital, acquired (including post‑traumatic, neoplastic, or systemic disease–related) deformities causing functional impairments (airway obstruction, speech/swallowing deficits, sinus dysfunction, nutritional compromise, facial asymmetry), but requires documentation of permanency, clinical photographs/models, imaging when feasible, and meeting specific measurement thresholds (e.g., asymmetry >3 mm, bilateral discrepancy ≥4 mm, transverse/vertical ≥2 SD, posterior open bite >2 mm); CT/3D planning is integral and not separately reimbursable, and Medicare/Humana medical‑necessity criteria must be met.
