Inspire HGNS denied due to quantity / dose limits 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 Issues a Quantity-Limits Denial for Inspire HGNS

For an implantable device like Inspire HGNS, a quantity-limits denial most commonly arises in one of these situations: (1) a request for a replacement or revision device when UHC's policy limits the frequency of implantation or replacement; (2) a request for components (such as a replacement remote or battery replacement/recharge accessories) that exceed what the policy allows per time period; or (3) a billing issue where a single procedure was coded in a way that appears to exceed allowed units. Identifying which scenario applies is the first step in building the appeal.

## Why This Denial Is Appealable

Quantity-limits denials are appealable when clinical circumstances justify an exception to the standard limit:

• Internal appeal (ACA §2719 / ERISA §503): Submit a full-and-fair internal appeal within the timeframe on the denial letter. Clearly explain why the clinical situation requires a quantity or frequency beyond the standard limit.
• External review: If the internal appeal fails, request independent external review under ACA §2719. The reviewer's decision is binding on UHC. The external-review request window is generally within four months of the final internal denial.
• Expedited review: Available for urgent situations, such as a failed or recalled device requiring immediate replacement.

## Documentation to Gather

1. Identify the specific limit exceeded: Obtain UHC's current published medical policy for hypoglossal nerve stimulation and identify the exact quantity or frequency limit being applied. 2. Clinical justification for additional quantity: The prescriber should document in the chart — and in a dedicated letter — the specific clinical reason the standard quantity is insufficient. For replacements, document device malfunction, battery end-of-life, or revision necessity with supporting records. 3. Device records: If this is a replacement request, document the original implant date, device model, and the clinical finding that necessitates replacement or revision. 4. Specialist attestation: The implanting surgeon or sleep specialist should attest that the additional unit or replacement is medically necessary and not merely elective. 5. Prior authorization for the original device: Include records showing the original device was properly authorized and implanted per UHC's criteria, establishing that this is a legitimate continuation of medically necessary treatment.

## Criteria-Mapping Structure

Structure the exception argument around UHC's own policy language for quantity exceptions:

| Quantity Limit (from UHC policy) | Clinical Exception Justification | |---|---| | [State the specific limit verbatim from the policy] | [Clinical findings, dates, and prescriber attestation explaining why the exception is warranted] |

Also confirm with the billing provider that the procedure codes submitted are correct — in some cases, a quantity-limits denial results from a coding error rather than a true policy limitation, and a corrected claim resolves the denial without a formal appeal.
