Inspire HGNS denied for missing prior authorization 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 for "Prior Authorization Required" — and How to Respond

Blue Cross Blue Shield requires prior authorization (PA) before it will cover the implantation of Inspire Upper Airway Stimulation (hypoglossal nerve stimulation, HGNS). A denial coded as "prior authorization required" typically means that no PA was obtained before the procedure was performed, the PA was requested but denied on clinical grounds, or the claim was submitted with codes that did not match what was authorized. Because the device involves a surgical implant procedure with significant cost, BCBS's prior-authorization requirement is strictly enforced. However, the denial is appealable in every scenario — the strategy differs depending on which of these situations applies.

## Federal Appeal Framework

ERISA §503 guarantees full-and-fair internal review for most employer-sponsored plans. ACA §2719 adds independent external review after internal appeals are exhausted. You typically have 180 days from the denial to file an internal appeal and approximately four months after a final internal denial to request external review. Expedited review (72-hour decision) is available when delay would seriously jeopardize health — for example, if the procedure is urgently needed and has not yet been performed.

## Your Concrete Appeal Steps

1. Identify the specific PA failure — review the EOB and call BCBS member services to determine: Was there no PA request at all? Was there a PA request that was denied? Or was there an approved PA but a coding mismatch on the claim? 2. If no PA was sought and the procedure has already occurred, file for a retroactive authorization appeal. Submit full clinical documentation with a prescriber's medical-necessity letter and argue that the procedure met all medical-necessity criteria at the time it was performed. 3. If the PA was denied clinically, appeal the clinical determination. This becomes a medical-necessity appeal — gather your sleep study, CPAP-intolerance records, prescriber letter, and specialist evaluation, and address each BCBS clinical criterion in your appeal. 4. If codes mismatched, work with the surgeon's billing team to correct the claim, attach the original PA approval letter, and resubmit. 5. Escalate to external review if internal appeals are unsuccessful.

## Documentation to Gather

• Original PA request and BCBS's response (approval or denial letter)
• Sleep study report confirming diagnosis and severity
• CPAP trial records with dates, adherence data, and documented outcome
• Specialist evaluation (sleep medicine, ENT) confirming candidacy
• Prescriber's medical-necessity letter addressing each BCBS policy criterion for Inspire HGNS
• Itemized claim and EOB showing the codes submitted versus what was authorized

## Criteria-Mapping Structure

Obtain BCBS's current medical policy for Inspire HGNS from your plan's medical policy portal. Create a table with columns: BCBS PA criterion (verbatim) | Your documentation | Specific chart fact. Address every criterion. For the procedural/administrative dimension, add a section documenting exactly what PA was or was not in place and why the coverage should be granted despite the administrative issue. Clarity and completeness are your strongest tools.
