Inspire HGNS denied as not FDA-approved for this use by Blue Cross Blue Shield?

Blue Cross Blue Shield'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 BCBS Denied Inspire HGNS as "Not FDA-Approved" — and Why You Can Challenge It

Inspire Upper Airway Stimulation (hypoglossal nerve stimulation, HGNS) received FDA premarket approval (PMA) as a Class III medical device for the treatment of moderate-to-severe obstructive sleep apnea in appropriate adult candidates. A denial from Blue Cross Blue Shield coded as "not FDA-approved" is therefore factually incorrect and is highly appealable. The most common root causes are: an outdated BCBS local medical policy that has not been updated since the device received approval; a claim coding error that caused the claim to be evaluated against the wrong policy; or a reviewer error. Because this denial rests on a verifiable factual error, it is one of the most straightforward to overturn.

## Federal Appeal Framework

ERISA §503 provides full-and-fair internal review rights for employer-sponsored plans, including the right to submit additional evidence and the right to know the specific basis for the denial. ACA §2719 adds independent external review. You generally have 180 days from the denial to file an internal appeal and approximately four months after the final internal denial to request external review. Expedited review (72-hour decision) is available when standard timelines would seriously jeopardize health.

## Your Concrete Appeal Steps

1. Obtain the FDA PMA approval documentation — go to accessdata.fda.gov, locate the PMA record for Inspire HGNS, and download the approval letter, approval order, and any applicable supplements. This is public-domain evidence and takes minutes to retrieve. 2. Obtain BCBS's denial policy — request in writing the specific BCBS medical policy under which the device was classified as not FDA-approved, and the policy's effective date. If the policy is outdated, that is grounds for the appeal itself. 3. Have your prescriber write a targeted letter — the letter should state that Inspire HGNS has received FDA PMA approval, identify the indication, and confirm that it is being used within that approved indication for your specific case. 4. File the formal internal appeal — submit it with the FDA approval documentation and the prescriber's letter, and explicitly state that the factual basis for the denial is incorrect. 5. Escalate to external review — if BCBS upholds the denial internally, file immediately for external review. An independent reviewer applying objective standards must acknowledge FDA approval.

## Documentation to Gather

• FDA PMA approval letter and approval order for Inspire HGNS (from accessdata.fda.gov)
• BCBS's denial letter and the specific policy cited
• Your prescriber's letter confirming approved indication and your diagnosis
• Sleep study confirming diagnosis
• CPAP intolerance records

## Criteria-Mapping Structure

In your appeal, lead with the FDA approval documentation. Create a one-page summary: BCBS's denial basis | FDA approval status | Supporting document. Then, anticipate that BCBS may shift to a medical-necessity argument once the FDA-approval objection is resolved — attach your clinical documentation preemptively so the appeal covers both grounds.
