Inspire HGNS denied as not medically necessary by UnitedHealthcare?

UnitedHealthcare'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 UnitedHealthcare Denies Inspire HGNS on Medical-Necessity Grounds

UnitedHealthcare's medical-necessity review for hypoglossal nerve stimulation (Inspire HGNS) is one of the most common denial types for this device. The insurer applies a clinical coverage policy that sets out specific patient-selection criteria — typically addressing the severity of obstructive sleep apnea, prior treatment history, anatomical considerations, and specialist evaluation requirements. When documentation does not clearly map each chart finding to each policy criterion, UHC's reviewers will issue a medical-necessity denial rather than approve the claim.

## Why This Denial Is Appealable

A medical-necessity denial is a coverage determination, not a clinical judgment that closes the door permanently. Federal law gives you robust appeal rights:

• Internal appeal (ACA §2719 / ERISA §503): You have the right to a full-and-fair internal review. Submit your appeal within the timeframe printed on your denial letter (typically 180 days for ERISA plans).
• External review: After exhausting the internal process — or if UHC fails to respond within required timeframes — you may request an independent external review. Under ACA §2719, the external reviewer's decision is binding on the insurer. The external-review request window is generally within four months of the final internal denial.
• Expedited review: If your condition is urgent or ongoing treatment is at risk, request an expedited internal and/or external review. Expedited decisions are typically required within 72 hours.

## Documentation to Gather

A successful appeal depends on assembling a complete evidence package. Collect the following categories:

1. Diagnosis confirmation: Sleep study report (polysomnography or home sleep test) with the relevant severity indices, interpreted and signed by a qualified sleep specialist. 2. Prior treatment history: Detailed record of CPAP or other positive airway pressure therapy — dates initiated, adherence data (download from the device if available), documented reasons for failure or intolerance, and the prescriber's clinical notes reflecting each attempt. 3. Clinical severity and comorbidities: Chart notes documenting how untreated or undertreated sleep apnea is affecting the patient's health, including any cardiovascular, metabolic, or neurocognitive sequelae documented by the treating physician. 4. Specialist evaluation: Otolaryngology (ENT) evaluation confirming anatomical suitability and endorsing the device as appropriate for this patient. 5. Prescriber medical-necessity letter: A detailed letter from the ordering physician stating the clinical rationale, explaining why alternative therapies are inadequate for this patient, and — critically — mapping each of UHC's published coverage criteria to a specific chart finding.

## Criteria-Mapping Structure

Obtain the exact criteria from two sources: (a) the FDA-approved labeling/instructions for use for Inspire HGNS, and (b) UnitedHealthcare's current published medical policy for hypoglossal nerve stimulation. Then build a table:

| Policy Requirement | Supporting Chart Evidence | |---|---| | [Copy each criterion from UHC's policy verbatim] | [Cite the exact date, document, and finding from the chart] |

Every criterion must have an answer. If a criterion is met, show the evidence. If a criterion is ambiguous, have the prescriber address it explicitly in the medical-necessity letter. Reviewers and external review organizations give significant weight to thorough, structured documentation that leaves no criterion unanswered.
