Confirm prior review rules and DME supplier eligibility for CPAP

Prior review requirements may apply per the member's Benefit Booklet and DME benefits; CPAP is covered under DME benefits. DME suppliers must meet the Plan's eligibility/credentialing requirements to be eligible for reimbursement.

• Check member Benefit Booklet for any prior review or benefit limitations for rental/purchase of CPAP equipment.
• Ensure DME supplier meets plan-defined eligibility/credentialing before billing for CPAP.

Attach medical necessity documentation for listed device/procedure codes

When submitting claims for devices or procedures listed in the policy, include documentation demonstrating medical necessity; inclusion of a code in the policy does not guarantee reimbursement.

• Custom fabricated OSA devices should be billed using E0486; include prescription and fabrication documentation when billing this code.
• Refer to the policy's Applicable Codes list (e.g., 42975, 94660, 95782–95811, A70xx series, E0485/E0486, E0561/E0562, E0601, G0398–G0400, K1027/K1037, S8040, 0964T–0966T) and attach supporting medical necessity evidence.

Submit current PSG and supporting records for surgical approvals

For any surgical approval request, submit current polysomnogram data (initial study, any CPAP titration data, and other studies performed) and supporting medical records; generally the sleep study used for approval must be less than 18 months old.

• Include the full PSG record (not just a summary) and supporting clinical notes.
• If prior surgical therapy exists, submit a repeat PSG when requested to support additional surgical therapy.

Document conservative therapy and CPAP titration/acclimation before alternatives

Conservative measures should be tried before initiating CPAP where appropriate, and CPAP titration plus documented acclimation and compliance efforts are required before alternative devices or surgery are covered.

• Document trials of weight loss, positional therapy, avoidance of alcohol/sedatives, and other conservative measures as clinically appropriate.
• Provide CPAP titration data and records of acclimation efforts (mask fitting, alternate interfaces, ramping, humidification, support) with compliance chip data.

Require CPAP trial and continuation attempts before oral appliance in severe OSA

Individuals with severe OSA should have an initial trial of CPAP and documented efforts to continue CPAP prior to switching to an oral appliance.

• Record CPAP trial details and attempts to maintain CPAP before authorizing oral appliance therapy for severe OSA.

Require failed conservative therapy and documented PAP attempts before surgery

Prior to surgical management, conservative measures appropriate to the clinical situation and a good-faith effort at positive airway pressure (CPAP/BiPAP) must be tried and failed; documentation of ongoing management by a sleep specialist for 3 months or greater may be required.

• Document attempts and failures of CPAP/BiPAP, including acclimation efforts and any compliance program participation.
• Include sleep specialist notes showing management for ≥3 months when relevant to a surgical request.

Ensure interpreter qualifications and include required clinical documentation elements

Documentation must confirm the testing modality and that the interpreting physician meets sleep medicine qualifications (ABSM certification, ABMS subspecialty certification, completion of required training pending first exam, or active staff membership of an AASM- or Joint Commission-accredited sleep center). Medical records must document symptoms (e.g., Epworth score), prior CPAP trials, device prescriptions, custom fabrication details for oral appliances, absence of TMJ/periodontal disease, and CPAP acclimation and compliance data.

• Include interpreter credentials per the four accepted verification options listed in the policy.
• Provide objective symptom documentation (e.g., pre-treatment Epworth >10 when relevant) and CPAP compliance chip readouts when claiming CPAP failure.

Provide complete medical records on request; letters alone may be insufficient

BCBSNC may request full medical records to determine medical necessity; letters of support alone are insufficient unless they contain all specific information needed for the medical necessity determination.

• When records are requested, provide complete study reports, clinician notes, device prescriptions, and compliance data rather than standalone letters.

Include required PSG report elements (TST, AHI/RDI, O2 metrics, desaturation durations)

Polysomnogram reports must include total sleep time; total RDI or AHI; average and lowest recorded oxygen saturation; for desaturations below 90%, the length of time at that saturation; obstructive event indices for supine and non-supine positions with total time supine; periodic limb movement index; and for CPAP titrations: optimum pressure, event index at that pressure, and total sleep time on CPAP.

• Ensure PSG report contains all listed elements when submitting for treatment authorization or surgical consideration.

Submit complete sleep study data; PSGs that omit positional event distinction may be insufficient

The Plan may require the complete polysomnogram data (not just summaries); a PSG that does not distinguish between supine and non-supine obstructive events may be incomplete and insufficient to support surgical requests.

• Provide full study records when requested and ensure positional event indices are reported to support surgical indications.

Denial risk when medical criteria or testing indications are not met

Treatments including CPAP, oral appliances, and surgical interventions will be denied when the policy's medical criteria and guidelines are not met; diagnostic testing for non-OSA conditions listed in the policy (e.g., bruxism, insomnia, restless leg syndrome, snoring without OSA) is not medically necessary.

• Do not submit claims for CPAP or other therapies unless objective criteria (AHI thresholds, symptom documentation, provider qualifications) in the policy are satisfied.
• Avoid requesting unattended sleep testing for conditions explicitly listed as not medically necessary.

CPAP and snoring-only treatments are noncovered if criteria unmet

CPAP is not covered when medical criteria and guidelines are not met; treatments for snoring without documented clinically significant OSA are considered not medically necessary and will be denied.

• Ensure diagnostic thresholds and required symptom documentation are met before requesting CPAP coverage.
• Do not bill for snoring-only interventions absent documented OSA per policy definitions.

Missing current PSG data may lead to denial of surgical requests

Surgical requests may be denied if current polysomnogram data (initial study, CPAP titration data, and other studies) are not submitted; generally the study upon which approval is requested must be less than 18 months old.

• Include the initial PSG, any CPAP titration study, and other relevant studies when requesting surgical authorization to avoid denial for incomplete documentation.
