Breast Pump denied as duplicate or overlapping therapy by Aetna?

Aetna's specific coverage criteria for breast pump 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 Your Breast Pump as Duplicate Therapy

A duplicate-therapy denial for a breast pump typically means Aetna's records show that a similar item of durable medical equipment (DME) was already provided or billed within a defined coverage period. This can happen due to a billing error, a prior rental that was converted to a purchase, or a legitimate need for a replacement device that Aetna's system has not recognized as distinct from a prior authorization. It is important to understand that under the ACA, non-grandfathered health plans are required to cover breastfeeding support and supplies — including breast pumps — without cost-sharing. A duplicate-therapy denial applied to a federally mandated benefit warrants a direct challenge.

## Your Federal Appeal Rights

• Internal appeal: Submit your appeal within the window stated on your Explanation of Benefits. Aetna must respond within 30 days (pre-service) or 60 days (post-service).
• External review (ACA §2719): After a final internal denial, you have approximately four months to request independent external review. This right applies to coverage disputes over federally mandated preventive benefits.
• ACA preventive-services mandate: Cite the ACA's preventive-services requirement (HRSA Women's Preventive Services Guidelines) as the coverage basis. A "duplicate" characterization must be reconciled with this obligation.
• Expedited review: If the denial affects an ongoing breastfeeding need with clinical urgency, request expedited review.

## What to Gather

1. Prior authorization and billing records — obtain EOBs and claims history to identify exactly what prior pump or DME was billed, when, and under what code. 2. Documentation distinguishing the current request — if the current pump is a replacement (due to damage, malfunction, changed clinical need, or a subsequent pregnancy), your clinician or supplier should document why it is not duplicative. 3. Supplier letter — written confirmation from the DME supplier of what was previously provided and why a new device is required. 4. Clinician's letter — if a replacement is medically necessary due to a clinical condition (e.g., NICU admission, low milk supply requiring a hospital-grade pump), the prescribing clinician should document the distinct medical necessity. 5. Aetna's DME policy — obtain the current policy on breast pump coverage and identify the replacement or duplicate criteria.

## Criteria-Mapping Structure

Identify the specific provision Aetna used to classify this as a duplicate. For each condition listed in that provision, note the chart or billing fact that distinguishes the current request. If the denial stems from a billing error, attach corrected claims documentation.

## Bottom Line

Duplicate-therapy denials on a federally mandated benefit like a breast pump are among the more straightforward appeals. Clear documentation showing either that no prior device was provided, that the prior device was distinct, or that a replacement is clinically warranted will typically resolve the denial.
