Complete concentric collapse at the velopharynx on DISE excludes candidacy for HGNS.
Hypoglossal nerve stimulation (adolescents/Down syndrome)
Covered when ALL of the following are met
Complete concentric collapse excludes candidacy for HGNS.
When Covered (surgical management) — summary
Surgical procedures may be considered medically necessary when ALL of the following are met:
Conservative measures include weight loss, positional therapy, avoidance of alcohol/sedatives, oral appliances, and smoking cessation.
Orthognathic surgery not approved as first surgical therapy unless higher-level obstruction ruled out.
Incomplete positional data may be insufficient to support approval.
Policy updated 4/1/24 to align with FDA indications.
Requests for surgical interventions that are not explicitly listed as covered in this policy will be denied. In addition, treatment of snoring alone (in the absence of documented obstructive sleep apnea) is considered not medically necessary; therefore any surgical procedure performed solely to treat snoring is not covered.
The following procedures are considered investigational or not medically necessary for snoring alone and/or for treatment of UARS or OSA: laser-assisted palatoplasty (LAUP); radiofrequency volumetric tissue reduction (RFVTR, Somnoplasty) or coblation of the palatal tissues or tongue; radiofrequency reduction or coblation of nasal turbinates; palatal stiffening procedures and palatal implants (e.g., Pillar, CAPSO, injection of sclerosing agents); tongue base suspension; and injection snoreplasty. These interventions are either explicitly not medically necessary for simple snoring or are considered investigational for UARS/OSA.
For candidacy for hypoglossal nerve stimulation (HGNS), complete concentric collapse at the level of the velopharynx on drug-induced sedation endoscopy (DISE) is an exclusion. Individuals demonstrating complete concentric velopharyngeal collapse on DISE are not considered candidates for HGNS based on device trial data and protocol exclusions.
Expanded lists of procedures deemed not medically necessary or investigational include: laser-assisted uvulopalatoplasty (LAUP); RFVTR/Somnoplasty of palatal tissues, tongue base, or nasal turbinates; palatal stiffening operations and palatal implants (e.g., Pillar, CAPSO, sclerosing injections); tongue base suspension; and injection snoreplasty. The policy states these techniques are not appropriate treatments for isolated snoring and are investigational for UARS or OSA.
Surgical procedures intended solely to treat snoring in the absence of documented OSA are considered not medically necessary. Because snoring without documented obstructive sleep apnea is not a disease meeting the definition of medical necessity, any surgical intervention for simple snoring is excluded from coverage.
The policy reiterates that treatment of snoring without documented OSA is not medically necessary and lists specific non-covered or investigational palatal procedures (palatal stiffening, palatal implants including Pillar, CAPSO, and injection sclerotherapy) and certain radiofrequency procedures. Providers should not submit requests for these procedures when the indication is simple snoring, as they will be denied.

Prior Authorization, Documentation, and Denial Risks
Prior review required with current PSG and conservative therapy documentation
Prior review is required for surgical requests and must include current polysomnography data (initial study and any CPAP titration data) and documentation of conservative management and CPAP acclimation efforts as applicable. Generally, the sleep study upon which approval is requested must be less than 18 months old.
- Polysomnography data must include total sleep time, total RDI/AHI, average and lowest O2 saturation, duration of desaturations below 90%, obstructive event indices for supine and non‑supine positions with time supine, PLM index, and a summary table of results and titrations.
- BCBSNC may request supporting medical records and documentation of conservative therapy and acclimation efforts.
Submit complete PSG and records for prior authorization; affected codes listed
Prior authorization submissions must include the complete polysomnogram record (initial study and CPAP titration data when applicable) and supporting medical records; the policy’s Billing/Coding section lists the affected CPT and HCPCS codes (including recently added device-related HCPCS codes).
- CPT/HCPCS codes listed in the policy include applicable surgical codes and device codes (see Billing/Coding section).
- Billing/Coding was updated to add HCPCS codes C8007–C8013 effective 4/1/26 and multiple CPT codes related to hypoglossal nerve stimulation.
Require documented trial and failure of conservative therapies and CPAP acclimation
A documented good‑faith effort at conservative therapies and positive airway pressure (CPAP/BiPAP/DPAP) must be tried and failed prior to surgical coverage; CPAP acclimation efforts should be documented and supported in the medical record.
- Conservative measures include weight loss, positional therapy, avoidance of alcohol/sedatives, oral appliances, and smoking cessation.
- CPAP acclimation efforts, when necessary, should be attempted for a minimum of two months with documentation and compliance chip information before CPAP is considered a failure.
Conservative (non‑surgical) measures and PAP trial required before surgery
Non‑surgical measures and a good‑faith effort at positive airway pressure must be tried and failed before surgical management will be approved; surgery is reserved for individuals who have not responded to appropriate medical alternatives.
- Conservative medical therapy examples: weight loss, avoidance of alcohol/sedatives, positional changes, oral appliances, positive airway pressure, medically supervised smoking cessation.
- Surgery is not first‑line and should follow failure of these non‑surgical measures.
Required PSG parameters and medical record documentation
Submit current polysomnogram data for any surgical approval request; reports must include total sleep time, total RDI or AHI, average and lowest oxygen saturation, length of desaturations below 90%, supine vs non‑supine obstructive event indices with time supine, PLM index, and a summary table of results and titration data.
- Include the initial sleep study and any CPAP titration data; the Plan may require the complete polysomnogram record, not just a summary.
- Polysomnography that does not distinguish between supine and non‑supine events may be considered incomplete and insufficient to support a surgical request.
Include initial study, CPAP titration, MSLT and supporting records for surgical requests
For surgical approval requests, submit the initial sleep study, any CPAP titration data, and any MSLT performed, along with supporting medical records; the Plan may request the complete polysomnogram at its discretion.
- CPAP titration details must include optimum pressure, event index at that pressure, and total sleep time on CPAP.
- Supporting medical records should document conservative therapy attempts and CPAP acclimation efforts if applicable.
Requests for non‑covered or investigational procedures will be denied
Requests for procedures not listed as covered, or listed as investigational or not medically necessary (e.g., laser-assisted palatoplasty, RFVTR/Somnoplasty, palatal stiffening procedures, tongue base suspension, injection snoreplasty), will be denied.
- Treatment of snoring alone (without documented OSA) is not medically necessary and any surgical intervention for snoring alone will be denied.
- Specific listed procedures (see policy exclusions) are considered investigational or not medically necessary for OSA/UARS and are excluded.
Incomplete, missing, or outdated sleep study data may lead to denial
Surgical requests may be denied if required polysomnogram data or supporting records are not submitted or if the sleep study is older than policy allowance (generally must be <18 months); incomplete polysomnograms that fail to distinguish supine vs non‑supine events may be insufficient to support approval.
- Generally, the sleep study upon which approval is requested must be less than 18 months old.
- A PSG that does not distinguish between supine and non‑supine obstructive events may be considered incomplete and may not support a surgical request.
Clinical Background
Obstructive sleep apnea (OSA) is characterized by repetitive upper airway obstruction during sleep leading to fragmented sleep and excessive daytime sleepiness. OSA is associated with increased cardiovascular and cerebrovascular risks, including hypertension, arrhythmias, pulmonary hypertension and stroke. Upper airway resistance syndrome (UARS) is a related condition in which increased airway resistance produces respiratory effort-related arousals without meeting criteria for apnea or hypopnea.
