Radiofrequency tissue volume reduction (e.g., Somnoplasty® device) is a minimally invasive procedure that utilizes low-power, low-temperature radiofrequency energy to produce thermal lesions in the soft palate and base of the tongue as a treatment of obstructive sleep apnea (OSA). The objective of radiofrequency tissue volume reduction is to decrease the amount of redundant tissue. The procedure is performed in the physician's office using local anesthesia and takes approximately thirty minutes to complete. By means of a partially insulated electrode, radiofrequency energy is delivered into the area through the submucosal tissue to make one or several coagulation lesions. The treated tissue is naturally absorbed over the next four to eight weeks.
Standard surgical procedures (i.e., uvulopalatopharyngoplasty [UPPP] and maxillofacial procedures) have been found to improve symptoms in adults with clinically significant obstruction. Minimally invasive surgical procedures have limited efficacy with mild-to-moderate OSA and have not been shown to improve Apnea/Hypoxia Index or excessive daytime sleepiness in adults with moderate to severe OSA.
Radiofrequency volumetric tissue reduction of the tongue and/or palatal tissues, for the treatment of obstructive sleep apnea or upper airway obstruction, is considered investigational.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits, or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
Studies in peer-reviewed literature are lacking to determine if radiofrequency tissue volume reduction is as beneficial as medical management or other surgical procedures for the treatment of upper airway obstruction.
