Medical Policy Bulletin

Title:Mentoplasty or Genioplasty

Policy #:11.14.01g

The Company makes decisions on coverage based on Policy Bulletins, benefit plan documents, and the member’s medical history and condition. Benefits may vary based on contract, and individual member benefits must be verified. The Company determines medical necessity only if the benefit exists and no contract exclusions are applicable.

When services can be administered in various settings, the Company reserves the right to reimburse only those services that are furnished in the most appropriate and cost-effective setting that is appropriate to the member’s medical needs and condition. This decision is based on the member’s current medical condition and any required monitoring or additional services that may coincide with the delivery of this service.

This Medical Policy Bulletin document describes the status of medical technology at the time the document was developed. Since that time, new technology may have emerged or new medical literature may have been published. This Medical Policy Bulletin will be reviewed regularly and be updated as scientific and medical literature becomes available. For more information on how Medical Policy Bulletins are developed, go to the About This Site section of this Medical Policy Web site.


Coverage is subject to the terms, conditions, and limitations of the member's contract.

When performed as a cosmetic service, mentoplasty or genioplasty is a benefit contract exclusion for all products of the Company and is not eligible for reimbursement consideration. However, mentoplasty or genioplasty is considered medically necessary and, therefore, covered to treat any of the following conditions:
  • Congenital craniofacial deformities such as, but not limited to, Pierre Robin syndrome
  • Craniofacial trauma with resultant facial asymmetry
  • Deformities related to radiation treatment and tumorous growths
  • Obstructive sleep apnea (OSA) that is documented by a physician with expertise in the area of sleep disordered breathing who definitively asserts that the proposed procedure is likely to significantly improve the identified abnormality. A diagnosis of OSA confirmed by sleep testing is required.
  • Lip incompetence that results in slurred speech, or xerostomia (dry mouth)
  • Systemic bone metabolic disorders that lead to speech and/or chewing dysfunction such as, but not limited to, fibrous dysplasia and acromegaly
  • Diseases that cause restriction of mandibular and chin development such as, but not limited to, rheumatoid arthritis
  • Craniofacial physiological function abnormalities, such as, but not limited to, facial fracture, iatrogenic disorder, or facial paralysis (e.g., Bell's palsy)

In exceptional circumstances where there is marked deformity resulting from severe local trauma, sequelae of radiation therapy, tumor, or severe congenital or acquired craniofacial anomaly, mentoplasty or genioplasty performed in the absence of additional maxillofacial procedures may be considered medically necessary and, therefore, covered. Photographs demonstrating the deformity may be required to determine coverage.


Mentoplasty or genioplasty performed solely to change the appearance of any portion of the face, without the expectation for improving physiologic functioning is considered a cosmetic service. Services that are cosmetic are a benefit contract exclusion for all products of the Company. Therefore, they are not eligible for reimbursement consideration.

Services performed due to recent trauma and/or accident may be eligible for coverage when performed within a year of the event or within a year of the time at which the member’s healing and/or skeletal and somatic maturation reasonably allows for repair and is intended to restore a member to a pre-trauma and/or pre-accident state, except when a specific benefit contract exclusion exists.


The individual's medical record must reflect the medical necessity for the care provided. These medical records may include, but are not limited to, records from the professional provider's office, hospital, nursing home, home health agencies, therapies, and test reports.

The Company may conduct reviews and audits of services to our members, regardless of the participation status of the provider. All documentation is to be available to the Company upon request. Failure to produce the requested information may result in a denial for the service.

All requests for mentoplasty or genioplasty require review by the Company and must include, but may not be limited to, color photographs and facial X-rays, letter of medical necessity from the provider, and results of any clinically indicated diagnostic studies to document the deformity.


Subject to the terms and conditions of the applicable benefit contract, mentoplasty or genioplasty is covered under the medical benefits of the Company's products when medical necessity criteria as listed in the medical policy are met.

Services that are cosmetic are a benefit contract exclusion for all products of the Company.


Mentoplasty and genioplasty are surgical procedures that alter the structure and appearance of an individual's chin. Mentoplasty, which is generally considered cosmetic in nature, reshapes the chin with an implant made of alloplastic material. Chin implants use a variety of materials, which may include silicone, metal, other man-made material, or allographic/tissue from an individual's own body. Implants with human tissue are semi-permanent because the tissue will age with time. Implants with metal or synthetic materials such as silicone or polythene are permanent.

Genioplasty involves the use of an inferior border osteotomy in order to advance or reduce the chin area. This procedure is most often performed for medical indications such as congenital deformities, craniofacial trauma with resultant facial asymmetry, and deformities related to radiation treatment and tumorous growths. A reduction genioplasty is permanent and may involve the removal of, or sliding of, bone tissue to reposition the chin point (i.e., osseous movement).

Mentoplasty or genioplasty is often performed during reconstructive surgical procedures to correct an underlying deformity (such as in the treatment of craniofacial deformities, craniofacial trauma, and surgically correctable causes of obstructive sleep apnea). Mentoplasty or genioplasty procedures are frequently performed in conjunction with other maxillofacial surgeries; however, they can sometimes be stand-alone procedures.

Although mentoplasty and genioplasty are designed to correct existing abnormalities or deformities of the chin to improve physiological function, they are sometimes solely cosmetic services to enhance the individual's appearance. Cosmetic services are those provided to improve an individual's physical appearance, from which no significant improvement in physiologic function can be expected. Emotional and/or psychological improvement does not constitute improvement in physiologic function.
