TAVR Low Risk denied due to quantity / dose limits by Aetna?

Q: How long do I have to appeal a Aetna TAVR Low Risk denial?

Internal appeal window: Typically 180 days from the denial date. External review window: Typically 60–120 days after the final internal denial. The clock starts from the date on the denial letter.

Quantity-limit denials usually flip when the appeal documents the clinically appropriate dose for the patient's weight, kidney function, or escalation schedule, citing the FDA label or specialty-society guideline.

US health-plan appeal rights

Cite: Most US health plans have appeal rights under either the ACA, ERISA, or Medicare/Medicaid rules

Most US health plans are required by federal law to give you both an internal appeal (where the insurer reconsiders) and an external review (where an independent reviewer decides). The exact timelines and processes depend on what kind of plan you have — marketplace / employer group, self-funded, Medicare Advantage, or Medicaid MCO — but in every case there's a window after the denial during which you have the right to fight it.

What Aetna typically requires

Aetna's specific coverage criteria for tavr low risk 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.

The Aetna angle on TAVR Low Risk

## Why Aetna Issues a Quantity-Limits Denial for TAVR

A quantity-limits denial for a structural heart procedure like TAVR most commonly arises when Aetna's system records a prior TAVR, a prior surgical aortic valve replacement, or a related structural heart intervention, and flags the current request as exceeding the number of covered interventions per policy period. It can also arise when the request involves components (e.g., additional valve sizing devices, imaging adjuncts) that are counted separately under the plan's benefit structure.

This denial is appealable when clinical circumstances justify the procedure. A patient who previously underwent TAVR and now requires a repeat procedure (valve-in-valve TAVR) is in a distinct clinical situation that most coverage policies recognize separately. Similarly, if the quantity limit is being applied in error — for example, counting a prior SAVR against a TAVR limit — that administrative error can be corrected on appeal.

## Federal Appeal Rights

You have the right to a full internal appeal under ERISA §503 or ACA §2719, followed by independent external review. The external review window is generally within four months of the final denial — confirm the exact date from your denial letter. Expedited review is available when delay poses a health risk.

## Appeal Process and Timeline

1. Clarify the basis of the quantity-limits denial: What prior procedure is Aetna counting, and what is the stated limit? Request the exact policy language. 2. Determine whether the limit is being applied in error (e.g., counting a different procedure type) or whether your case genuinely involves a repeat intervention. 3. File a Level 1 internal appeal with documentation demonstrating either the error or the medical necessity of a repeat/valve-in-valve procedure. 4. Escalate to external review if the internal appeal is denied.

## Documentation to Gather

Procedure history: Complete records of all prior cardiac valve procedures with dates, procedure types, and diagnoses — to establish exactly what has been performed and whether Aetna is applying its count correctly.
Current diagnosis and necessity: Echocardiographic and clinical documentation establishing the indication for the current TAVR request — including evidence of valve failure, re-stenosis, or a new clinical indication if this is a repeat procedure.
Structural heart team letter: A detailed letter from your interventional cardiologist and cardiothoracic surgery team explaining why this procedure is medically necessary and, if applicable, why it is clinically distinct from any prior intervention.
Applicable guidelines: Your physician can reference current ACC/AHA guidance on valve-in-valve procedures or repeat structural interventions to support the clinical rationale.
Benefit plan language: Obtain the exact quantity-limits provision from your Summary Plan Description or Evidence of Coverage document.

## Criteria-Mapping Structure

Create a chronological procedure history table and map it against Aetna's quantity-limit rule verbatim. If the limit is being applied to the wrong procedure type, make that error explicit with supporting documentation. If this is a medically justified repeat procedure, present a separate clinical-necessity argument showing that the current intervention meets all coverage criteria independent of the quantity-limit provision.
