BRCA Single Gene denied as non-formulary by Aetna?

Aetna's specific coverage criteria for brca single gene 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 Denies BRCA Single-Gene Testing as Non-Formulary

While "non-formulary" terminology typically applies to pharmacy benefits, Aetna's laboratory and diagnostic-testing benefits sometimes apply an analogous tier structure — preferring contracted laboratories or specific test configurations and classifying out-of-network or non-preferred laboratory submissions as non-covered or requiring additional authorization. A non-formulary denial for BRCA single-gene testing may also reflect that the ordering provider submitted to a laboratory not included in Aetna's preferred laboratory network, or that the specific test code used does not match Aetna's covered test configuration.

## Federal Appeal Rights

Under ACA §2719, non-formulary or non-covered-service denials on non-grandfathered plans are appealable through internal review and then independent external review by an IRO. ERISA self-funded plans carry equivalent rights under ERISA §503. The external-review window is generally four months from the final internal denial. Expedited review is available where clinical urgency applies.

## Appeal Process and Timeline

1. Identify the specific basis — request written clarification on whether the denial is based on the laboratory, the test code, or the test configuration. 2. Check Aetna's preferred laboratory directory and determine whether retesting at a preferred laboratory is clinically feasible and appropriate. 3. File the internal appeal if retesting is not feasible or appropriate, with documentation supporting coverage at the submitted laboratory. 4. Request an exception to the preferred-laboratory requirement if use of the specific laboratory was medically justified (e.g., the laboratory holds the only clinically validated assay for a specific variant, or the sample was already processed). 5. Escalate to external review if the internal appeal is denied.

## Documentation to Gather

• Explanation of the laboratory choice: a clinician or genetic counselor statement explaining why the specific laboratory was used and why a preferred-laboratory alternative was not appropriate.
• Clinical records establishing medical necessity: full personal and family history, genetic counseling notes, and ordering clinician letter as described under the medical-necessity appeal type.
• Test requisition and result documentation: the laboratory order form and any results received, to establish what was performed and why.
• Network exception request documentation: if applicable, a formal network exception or gap-in-network request, particularly if the required test is not available from a preferred laboratory.

## Criteria-Mapping Strategy

Obtain Aetna's Laboratory Management Clinical Policy and its preferred-laboratory exception criteria. Map the clinical circumstances — particularly any unique-assay or sample-integrity rationale — against each exception criterion. If the denial is purely administrative (wrong test code or laboratory code), a corrected claim or administrative resubmission may resolve it without a formal appeal.
