Inspire HGNS denied as not medically necessary by Aetna?

Aetna's specific coverage criteria for inspire hgns are defined in its own published medical/coverage policy and the FDA-approved prescribing label. A successful appeal documents that your medical records satisfy each criterion those sources list — confirmed diagnosis, any required prior treatments (with dates and outcomes), and clinical severity. If the exact criteria weren't included with your denial, request them in writing; your appeal then maps each requirement to the matching fact in your chart.

## Why Aetna Denies Inspire HGNS on Medical-Necessity Grounds

Aetna's medical-necessity denials for Inspire hypoglossal nerve stimulation (HGNS) typically occur when the submitted clinical record does not document each criterion in Aetna's published clinical policy bulletin for this device. Aetna's policy for HGNS is specific and multi-part: it includes requirements related to the severity of obstructive sleep apnea, the adequacy and outcome of prior PAP therapy, anatomical characteristics, and in some cases the results of drug-induced sleep endoscopy (DISE). A denial at this stage usually means one or more of those criteria was either not addressed in the documentation or was documented in a way that did not satisfy the reviewer.

## Why This Denial Is Appealable

Medical-necessity denials based on Aetna's clinical policy are directly tied to the documentation submitted. If the clinical record supports Inspire and the denial reflects an incomplete submission — or a reviewer's misreading of the record — an appeal with complete, well-organized documentation succeeds regularly. Your prescribing physician and the implanting surgeon are essential partners in identifying exactly which criterion the reviewer found unsatisfied and correcting the record.

## Your Federal Appeal Rights

• Internal appeal (ACA §2719): File a written internal appeal. Aetna is required to have a physician reviewer with relevant specialty expertise conduct the review.
• Peer-to-peer review: The implanting surgeon or referring sleep specialist should request a peer-to-peer with Aetna's medical director. This call often resolves medical-necessity denials when the clinician can speak directly to the chart findings.
• External review: After exhausting internal appeals, request independent external review. The reviewer applies clinical standards, not Aetna's internal policy preferences.
• ERISA §503: For employer self-funded plans, demand the complete administrative record, including Aetna's clinical review notes.
• Expedited review: Available if delay poses significant health risk.
• Timeline: File external review within four months of the final internal adverse determination.

## Documentation to Gather

1. Sleep study records: Full polysomnography or home sleep testing results with interpretation, establishing the diagnosis and severity of obstructive sleep apnea. 2. PAP therapy trial documentation: Objective CPAP or BiPAP compliance data (downloaded from the device), clinical notes on adherence counseling, documented intolerance or failure. 3. Anatomical and DISE findings: If drug-induced sleep endoscopy was performed, include the operative or procedural report. If Aetna's policy requires specific anatomical findings, confirm those are documented by the surgeon. 4. Body habitus / BMI documentation: Aetna's policy includes anatomical and physical criteria — ensure the clinical record reflects the relevant findings as documented by the treating team. Do not rely on the appeal letter alone; the chart must support each criterion. 5. Prescriber and surgeon letters: A joint or coordinated letter from the sleep medicine physician and the ENT/implanting surgeon addressing each Aetna criterion by name, with specific chart citations. 6. Aetna's clinical policy bulletin: Read the current version carefully before writing the appeal. Match every criterion to a chart finding.

## Criteria-Mapping Structure

Obtain Aetna's current clinical policy bulletin for hypoglossal nerve stimulation. Create a table with every listed coverage criterion in the left column and the specific chart entry — date, clinician, finding — satisfying it in the right column. Where Aetna's policy references the FDA-approved prescribing information or indications, cross-reference those as well. Submit this table as an exhibit to the prescriber letters. This format transforms a narrative dispute into a checklist that the reviewer must address criterion by criterion.
