Gas Top denied as experimental or investigational by Aetna?

Aetna's specific coverage criteria for gas top 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 Denied a Gastric Balloon as Experimental or Investigational

Aetna applies an "experimental or investigational" (E&I) label when it concludes that the evidence base for a treatment does not yet meet its internal standard for clinical effectiveness. For intragastric balloons, this denial can appear even though FDA-cleared devices exist in this category — Aetna's coverage determination is separate from FDA clearance and is driven by its own clinical policy.

This denial is worth appealing because FDA market clearance, peer-reviewed literature, and professional society endorsement can collectively rebut an E&I classification. The key is showing that the treatment meets the plan's own definition of "established" care for your specific diagnosis.

## Your Federal Appeal Rights

• Internal appeal (ACA §2719 / ERISA §503): You are entitled to a written explanation of precisely which evidence criteria the treatment failed. Submit your appeal within the window stated on your denial notice.
• External review: After exhausting internal appeals, request IRO review. The standard external-review deadline under ACA is within four months of a final adverse determination. IRO reviewers must be independent of Aetna.
• Expedited review: Available if delay would seriously jeopardize health. Request it in writing at the same time as your standard appeal.

## Building a Strong Appeal

### Documentation to Gather

1. FDA clearance documentation: Confirm the specific device prescribed carries FDA 510(k) clearance or PMA approval and include that designation in your appeal letter. 2. Professional society position: Obtain a statement or reference to a position paper from the applicable guideline organization (such as the American Society for Metabolic and Bariatric Surgery or equivalent) acknowledging intragastric balloons as a recognized treatment modality. 3. Peer-reviewed literature: Your prescriber can cite published systematic reviews or meta-analyses — without quoting statistics — to show the treatment has a recognized evidence base. 4. Prescriber medical-necessity letter: Should explain why established surgical or pharmacologic alternatives are not appropriate or sufficient for you, and why the balloon is the evidence-supported choice for your clinical situation. 5. Aetna's E&I policy definition: Pull Aetna's published criteria for what constitutes "experimental." Map each criterion to the available evidence. If FDA clearance alone should satisfy one criterion, say so explicitly.

### Criteria-Mapping Structure

List each element of Aetna's E&I definition verbatim. Opposite each element, provide a one-sentence response grounded in documented evidence (FDA status, guideline recognition, peer-reviewed literature). Do not leave any criterion unaddressed — a single unanswered element gives the reviewer a reason to uphold the denial.

## Key Message to Your Prescriber

The strongest E&I appeals come from prescribers who can articulate that: (a) the device is FDA-cleared for the intended use, (b) a recognized professional society has accepted this modality in its guidance, and (c) the treatment is not being used outside of its cleared indication. Generic "I believe this is necessary" letters are insufficient — specificity about evidence status wins these appeals.
