BRCA Single Gene denied as not medically necessary 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 for Medical Necessity

Aetna's medical-necessity standard for BRCA single-gene testing requires that the patient's personal and/or family history meet the clinical criteria specified in its published Clinical Policy Bulletin. Denials typically occur because the submitted documentation does not clearly establish that the patient meets those criteria, not because the test is inherently non-covered. This is one of the most correctable denial types when the appeal includes complete, organized clinical history.

## Federal Appeal Rights

Medical-necessity denials for genetic testing are subject to the full appeal process under ACA §2719 (non-ERISA plans) and ERISA §503 (self-funded plans). After the internal appeal, you may request independent external review by an IRO within four months of the final internal denial. The IRO applies the plan's own medical-necessity criteria and is not bound to defer to Aetna's initial determination. Expedited review is available when a treatment decision is time-sensitive.

## Appeal Process and Timeline

1. Request the denial letter specifying which medical-necessity criterion was not met. 2. Pull Aetna's Clinical Policy Bulletin for BRCA testing and map the unmet criterion against your clinical record. 3. File the internal appeal with the gap in documentation filled; pre-service appeals must be decided within 30 days. 4. Escalate to external review if denied again, within four months.

## Documentation to Gather

• Complete personal and family history: a three-generation pedigree or equivalent narrative detailing cancer diagnoses in first- and second-degree relatives, with ages at diagnosis, cancer types, and bilateral or multiple-primary status where applicable.
• Genetic counseling notes: documentation of a formal genetic counseling session or a clinician's risk assessment is frequently required; confirm what Aetna's policy specifies.
• Oncology/pathology records: for affected patients, tumor type, stage, receptor status, and any prior genetic testing results that inform why additional testing is ordered.
• Ordering clinician medical-necessity letter: a narrative linking the patient's specific history to the applicable NCCN, ASCO, or USPSTF guideline criteria for testing, without quoting specific numeric thresholds — instead, reference that the patient's history meets the criteria as described in the current guideline.
• Prior test results (if any): to confirm this test addresses a distinct clinical question.

## Criteria-Mapping Strategy

Download Aetna's current Clinical Policy Bulletin for hereditary BRCA testing. Create a side-by-side table listing each criterion alongside the specific patient record or history element that satisfies it. Submit the pedigree, counseling notes, and medical-necessity letter as indexed exhibits. Appeals that mirror the policy's own language and provide complete documented evidence for each criterion consistently achieve the best outcomes.
