Medical Policy

Title:

Mentoplasty or Genioplasty

Policy #:

MA11.080c

Policy

When performed as a cosmetic service, mentoplasty or genioplasty is not covered by the Company because cosmetic services are not covered by Medicare. Therefore, it 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.

COSMETIC

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 and, therefore, not covered by the Company because cosmetic services are not covered by Medicare. Therefore, it is 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 not covered by Medicare.

REQUIRED DOCUMENTATION

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.

Guidelines

There is no Medicare coverage determination addressing mentoplasty or genioplasty; therefore, the Company policy is applicable.

BENEFIT APPLICATION

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

Services that are cosmetic are excluded for the Company's Medicare Advantage plans because they are not covered by Medicare. Therefore, they are not eligible for reimbursement consideration.

Description

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 semipermanent 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 the medical indications listed in the Policy section. A reduction genioplasty is permanent and may involve the removal of, or sliding of, bone tissue to reposition the chin point.

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.
