Coverage Summary

This Pennsylvania-specific policy (CS088PA.V) defines UnitedHealthcare Community Plan medical coverage criteria for Orthognathic (Jaw) Surgery. The policy status is CURRENT and applies only to members in the state of Pennsylvania; requests that do not meet the Pennsylvania criteria will be evaluated case-by-case with reference to Pennsylvania Exceptions and PA Code Title 55, Chapter 1101. The policy effective date is April 1, 2026 and the last review date is April 1, 2026.

Provider Actions & Prior Authorization

Documentation Required

Document skeletal measurements and functional impairment

Provider must document clinical measurements that meet the numeric thresholds and document one or more functional impairments to support reconstructive medical necessity. Required skeletal measurements include horizontal incisor overjet and molar relationship (anteroposterior), transverse measurements or asymmetry measurements, and vertical deviation/open bite findings. Functional impairments include masticatory and swallowing dysfunction (e.g., inability to bite or chew solid foods, choking on incompletely masticated foods, damage to soft tissue during mastication, malnutrition) or documented speech impairment due to the facial skeletal deformity.

Anteroposterior: horizontal incisor overjet ≥ 5 mm or 0 to negative value; molar discrepancy ≥ 4 mm (norm 0–1 mm)
Transverse: transverse skeletal discrepancy ≥ two standard deviations or total bilateral palatal cusp to mandibular fossa discrepancy ≥ 4 mm (or unilateral ≥ 3 mm)
Vertical/asymmetry: vertical deformity ≥ two standard deviations from norms, or open bite (no anterior vertical overlap or posterior open bite > 2 mm), deep overbite with soft tissue impingement, supraeruption
Functional impairments: masticatory/swallowing dysfunction (inability to bite/chew solid foods; choking on incompletely masticated foods; damage to soft tissue during mastication; malnutrition) or documented speech impairment

Prior Authorization

Prior authorization / case-by-case review

Requests for services that do not meet the Pennsylvania-specific criteria, or requests for members outside Pennsylvania, will be evaluated on a case-by-case basis. Follow Pennsylvania Exceptions and reference the Pennsylvania Code (Title 55, Chapter 1101) when applying state-specific determinations.

Applies to Pennsylvania only; see PA Code Title 55, Chapter 1101 for Pennsylvania Exceptions

Documentation Required

Exclude cosmetic-only indications

Providers must indicate if the procedure is primarily cosmetic. Procedures that correct an anatomical congenital anomaly without improving or restoring physiologic function are considered cosmetic and orthognathic surgery performed for cosmetic purposes only is not medically necessary per the policy and Pennsylvania code definitions.

Cosmetic procedures are those primarily to improve appearance; refer to 55 Pa. Code § 1141.2 and noncompensable services guidance in 55 Pa. Code § 1141.59
Orthognathic surgery for cosmetic purposes only is not considered reconstructive or medically necessary

Background & Evidence

Orthognathic surgery corrects skeletal abnormalities of the mandible and/or maxilla to improve facial form and function and may be performed for congenital anomalies, trauma, or disease; it is often combined with orthodontic therapy. Clinical guidance from the American Association of Oral and Maxillofacial Surgeons (AAOMS) and systematic reviews inform the policy: AAOMS provides numeric thresholds for anteroposterior, vertical, transverse discrepancies and asymmetries used in coverage criteria, and systematic reviews report that orthognathic surgery improves masticatory performance though it may not restore normal occlusion and that long-term stability evidence is variable.

Evidence	Findings
Systematic review (Bunpu et al., 2023)
Orthognathic surgery improves masticatory performance but may not reach normal occlusion; 21 studies included (1238 individuals); follow-up 2 weeks to 5 years.
Systematic review (Mulier et al., 2021)
Long-term stability variable; limited evidence with follow-up 5-15 years; recommendations for further prospective studies.
AAOMS Clinical Guidelines (2025)
Provides numeric thresholds for anteroposterior, vertical, transverse discrepancies and asymmetries used in coverage criteria (e.g., overjet ≥5 mm or 0 to negative; molar discrepancy ≥4 mm; vertical/transverse deviations ≥2 SD; bilateral palatal cusp to mandibular fossa ≥4 mm or unilateral ≥3 mm; asymmetry >3 mm).
