Defines coverage, coding, and clinical background for use of intraoral (dental) appliances to treat obstructive sleep apnea (OSA) for Medicare Advantage and commercial members; excludes appliances for non-OSA indications and several novel OSA devices.
No material clinical or coverage changes in this revision.
Coverage Criteria for Oral Appliances
Covered Oral Appliance Therapy
Covered when ALL of the following are met:
Includes custom fabricated and prefabricated devices (HCPCS E0486, E0485).
Additional visits beyond three are the member's responsibility unless an additional device is supplied.
Not Covered / Not Medically Necessary
The following devices/uses are not covered or are considered not medically necessary:
Relevant non-covered/not medically necessary codes cited include A7047 (oral interface for OPT/Winx), K1001 (positional device), and use of E1399 for unlisted non-invasive tongue stimulator devices.
Devices marketed solely for the treatment of snoring when not associated with obstructive sleep apnea are excluded from coverage. Over-the-counter (OTC) oral appliances are not covered because they have not demonstrated equivalent effectiveness to custom-fitted oral appliances for OSA. Oral appliances used to treat non-OSA dental conditions such as temporomandibular joint disorder (TMJ) or bruxism (tooth grinding) are also excluded from coverage for all product lines.
Medically necessary services that are nevertheless non-covered benefits may not be charged to the member unless the provider has informed the member in advance and the member has provided written agreement to continue the treatment at their own expense. Verify member-specific benefits and eligibility prior to providing services, since subscriber or employer agreements determine final coverage.
The following technologies are considered not medically necessary or have insufficient evidence to support coverage: nasal expiratory positive airway pressure (EPAP) devices (eg, PROVENT), oral pressure therapy systems (eg, Winx™), palate and mandible expansion devices (eg, DNA and mRNA appliances), daytime tongue stimulation devices (eg, eXciteOSA), and sleep-positioning trainers that use vibration (eg, NightBalance). When no specific code exists, claims for devices such as non-invasive tongue stimulators should be filed using the applicable unlisted DME code (eg, E1399). Specific HCPCS codes cited as not medically necessary include A7047 (oral interface used with OPT) and K1001 (electronic positional OSA treatment).
Services determined to be not medically necessary may be denied and, except where the member was informed and provided written agreement in advance, the provider may not bill the member for those services. Providers should follow participation agreements and verify whether a prior written financial agreement exists before charging members for non-covered or not medically necessary services.
Coding and Billing

| K1001 | Electronic positional obstructive sleep apnea treatment, with sensor, includes all components and accessories, any type |

Provider Actions and Billing Requirements
Prior Authorization
Prior authorization review is not required.
Verify Benefits and Eligibility
Verify member-specific benefits and eligibility with the payer prior to providing services. Benefits and eligibility are determined by the member's subscriber agreement, member certificate, or employer agreement and may supersede this policy. For information on member-specific benefits, call the provider call center.
First-line Therapy Context
CPAP is supported by evidence as more effective than oral appliances and is considered first-line therapy for treating obstructive sleep apnea (OSA). Oral appliances are an alternative for documented mild to moderate OSA when appropriate.
Non-covered Indications
Devices marketed for snoring not associated with sleep apnea, over-the-counter oral appliances, and oral appliances used to treat temporomandibular joint disease (TMJ) or bruxism are non-covered. Nasal expiratory positive airway pressure, oral pressure therapy, and palate/mandible expansion devices are considered not medically necessary.
Provider Documentation and Billing Notes
Fitting and appliance services (initial evaluation, oral/dental impressions, fabrication, initial fitting, patient education, teaching, and three follow-up visits) are considered inclusive in the global fee for the device; additional visits beyond the three follow-up visits are the member's responsibility unless an additional device is supplied. Cephalometric X-rays (with and without the appliance) may be billed separately as diagnostic testing services. Replacement and repairs are covered per the Durable Medical Equipment Repair and Replacement policy; medical review/preauthorization is not required for repair/replacement. The member is responsible for applicable DME copayments, coinsurance, and/or deductibles.

- Replacement and repairs follow the DME Repair and Replacement policy; no preauthorization required for repair/replacement
- Member responsible for applicable DME copayments, coinsurance, and deductibles
Clinical Background
Obstructive sleep apnea (OSA) is characterized by repeated episodes of upper airway collapse during sleep leading to hypoxemia and sleep fragmentation, which manifest clinically as snoring, excessive daytime sleepiness, and other functional impairments. OSA can have cardiovascular and pulmonary consequences. Oral appliances — including mandibular advancement/positioning devices and tongue-retaining devices — are treatment options, particularly for mild-to-moderate OSA, but continuous positive airway pressure (CPAP) is generally supported by evidence as the more effective first-line therapy.
