LVAD DT denied due to quantity / dose limits by Aetna?

Aetna's specific coverage criteria for lvad dt 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 Applied a Quantity Limit to Your LVAD Destination Therapy — And Why You Can Appeal

For LVAD destination therapy, a quantity-limit denial is unusual in the sense that LVADs are not dispensed like medications — but Aetna's coverage policies can impose limits on related components, replacement parts, implant supplies, or can apply policy restrictions that function as quantity-based constraints (for example, limiting coverage to a single implant event or restricting the number of approved device exchanges). Understanding exactly what Aetna's limit covers, and why your clinical situation requires what is being requested, is the foundation of a successful appeal.

## Why This Denial Is Appealable

Quantity-limit denials are appealed on medical-necessity grounds: the patient's clinical circumstances require what is being requested, and applying the limit causes clinical harm. If the request involves a device exchange, component replacement, or a second implant event due to device malfunction, infection, or clinical need, your appeal should document in detail why the additional quantity is medically necessary and not duplicative.

## Federal Appeal Framework

• Internal appeal: File a written internal appeal within the timeframe stated in the denial letter. For urgent cardiac situations, an expedited appeal must be decided within 72 hours.
• External review (ACA §2719): After exhausting the internal appeal process, an independent IRO external review is available. This window is generally open within four months of the final internal denial.
• Expedited external review: Available for urgent situations alongside an expedited internal appeal.
• ERISA §503: Employer-sponsored plans must conduct a full-and-fair review incorporating all submitted clinical evidence.

## Documentation to Gather

• Clinical indication for the additional quantity: chart records specifically documenting why the request exceeds Aetna's standard limit — device failure, infection, thrombus, component malfunction, or other medically necessary indication
• Device and implant records: serial numbers, implant dates, and (if applicable) documentation of the prior device's performance or failure
• Cardiology and surgical notes: supporting the clinical necessity of the requested intervention
• Prescriber medical-necessity letter: written by the implanting cardiac surgeon or heart failure cardiologist, explicitly explaining why the quantity limit should not apply to this patient's situation
• Aetna's coverage policy: identify the exact language in Aetna's clinical policy bulletin that establishes the limit, and address it directly
• Applicable guideline organization position: reference to the relevant professional society guideline organization (without citing specific numbers) supporting the approach your team is recommending

## Criteria-Mapping Structure

Your appeal letter should open by identifying the specific quantity limitation Aetna applied, then provide a point-by-point clinical justification for why your situation falls outside the standard application of that limit. Each paragraph should cite a specific chart document and date. The goal is to show that applying the limit in your case is not consistent with medically necessary care as defined by the applicable clinical standard. Attach all referenced records as labeled exhibits.
