TAVR Low Risk denied for failing step therapy by Aetna?
Step-therapy denials usually flip when the appeal documents that prior alternatives were tried and failed, or were contraindicated, or aren't safe for the patient.
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 May Deny TAVR for Low Surgical Risk Under Step Therapy
A step-therapy denial for TAVR is uncommon but can occur when Aetna's policy requires documentation that less-invasive or less-resource-intensive options were considered and found inadequate before approving a major structural heart procedure. In practice, this most often means Aetna wants evidence that medical management of aortic stenosis was appropriately trialed or evaluated and that the patient's condition has progressed to the point where a procedural intervention is required. It can also reflect an Aetna requirement that SAVR be considered before TAVR in certain risk profiles.
This denial is appealable because aortic stenosis — particularly severe aortic stenosis — has no proven pharmacologic therapy that reverses or halts disease progression. Current professional society guidelines do not recommend indefinite medical management as a step before procedural intervention in patients who meet criteria for valve replacement. The treating structural heart team's documentation that medical management is not an appropriate alternative is a strong basis for appeal.
## Federal Appeal Rights
You have the right to a full internal appeal under ERISA §503 or ACA §2719. If the internal appeal is denied, you may request independent external review, typically within four months of the final denial — confirm the exact date from your denial letter. Expedited review is available when clinical urgency applies.
## Appeal Process and Timeline
1. Obtain the step-therapy requirement in writing — the denial letter must specify what prior step(s) Aetna requires and which criteria are unmet. 2. Determine whether a step-therapy exception applies — most state and federal step-therapy laws include exceptions when the required step is contraindicated, clinically inappropriate, or has already been tried. 3. File a Level 1 internal appeal with a letter from your structural heart team explaining why medical management is not an appropriate prior step for your clinical situation. 4. Escalate to external review if denied.
## Documentation to Gather
- Disease severity and natural history documentation: Echocardiographic reports and clinical notes confirming the severity and trajectory of aortic stenosis, establishing why deferral for additional medical management would be harmful.
- Medical management history: Any records of prior attempts at symptom management, heart failure therapy, or other medical interventions — including outcomes — so Aetna can see what has been tried.
- Prescriber letter on step-therapy exception: A detailed letter from your cardiologist and structural heart team explaining why the step-therapy requirement is clinically inappropriate for your situation, and citing the relevant professional society guidelines that endorse procedural intervention at your severity level.
- SAVR vs. TAVR comparison: If Aetna is requiring SAVR as a prior step, include the surgical risk assessment and a clinical explanation of why TAVR is the appropriate procedural choice for your anatomy and risk profile.
- Applicable guidelines: Your physician can reference current ACC/AHA valvular heart disease guidelines to support the position that medical management is not a recognized prior step for severe, symptomatic aortic stenosis.
## Criteria-Mapping Structure
Obtain Aetna's exact step-therapy criteria and map each requirement against your clinical record. For each required step, either show it has been completed (with dates and outcomes) or provide the clinical rationale — supported by your physician's letter and guideline references — for why that step is not appropriate in your case. A step-by-step rebuttal format is essential for both internal reviewers and external review organizations.
