Gas Top denied as non-formulary 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 Non-Formulary

For device-based treatments like intragastric balloons, a "non-formulary" denial signals that the specific product or the procedure itself is not included in Aetna's covered benefits list for your plan, or that it sits on a tier requiring additional authorization. Unlike drug formulary tiers, device coverage is governed by your plan's medical benefit and its associated clinical policy — not a pharmacy benefit.

This denial type does not necessarily mean the treatment can never be covered. It often means you must use the formulary exception or medical-necessity pathway to establish that your clinical circumstances justify coverage despite the default non-formulary status.

## Your Federal Appeal Rights

• Formulary exception request: Before filing a formal appeal, request a formulary (or coverage) exception in writing. Your prescriber must attest that all covered alternatives are clinically inappropriate for you.
• Internal appeal (ACA §2719 / ERISA §503): If the exception is denied, escalate to a formal internal appeal. Submit within the deadline on your denial notice.
• External review: After the internal appeal, you have the right to IRO review. The four-month external-review window runs from the final internal denial date.
• Expedited review: Request expedited processing if clinical urgency applies.

## Building a Strong Appeal

### Documentation to Gather

1. Plan benefit document (SPD/EOC): Obtain your Summary Plan Description or Evidence of Coverage. Confirm whether intragastric balloons are explicitly excluded or simply unlisted. An unlisted item is not the same as a categorical exclusion. 2. Covered-alternative contraindication or failure: Aetna will ask why you cannot use a covered alternative. Your prescriber must document, with chart support, that covered alternatives are medically inappropriate, were tried and failed, or carry risks that outweigh benefits for your specific situation. 3. Prescriber medical-necessity letter: Must specifically address why the non-formulary device is required rather than any covered substitute, citing your clinical history and current condition. 4. Prior treatment history with dates and outcomes: Demonstrates that the pathway to this treatment was clinically appropriate and that lower-tier options were exhausted. 5. Diagnosis and comorbidity documentation: Supports the urgency argument and distinguishes your case from an elective preference.

### Criteria-Mapping Structure

Identify the formulary exception criteria in Aetna's policy for your plan type. Map each criterion to a specific chart document. Pay particular attention to the "all covered alternatives are contraindicated or ineffective" requirement — this is where most non-formulary exceptions succeed or fail. If your prescriber cannot document at least one covered alternative as inadequate, the exception will likely be denied regardless of other factors.

## Key Message to Your Prescriber

Non-formulary appeals hinge on the comparative argument: not just that the requested treatment is good, but that the covered alternatives are insufficient for this patient. A letter that explains the specific clinical reason why each covered alternative was considered and rejected — with chart-supported reasoning — is far more persuasive than one that simply states the requested device is the best option.
