TAVR Low Risk denied as not medically necessary by Aetna?

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.

## Why Aetna Denies TAVR for Low Surgical Risk on Medical-Necessity Grounds

A medical-necessity denial means Aetna's reviewer concluded that TAVR is not required for your specific clinical situation — often because the documentation submitted did not clearly establish that your aortic stenosis has reached the severity threshold Aetna's policy requires, that alternative interventions are inadequate, or that your clinical profile matches the criteria in Aetna's coverage policy for low-surgical-risk TAVR. This is the most common denial type for structural heart procedures and is also among the most successfully appealed.

Medical-necessity denials turn on documentation quality. If your records are complete and your treating team documents their clinical reasoning explicitly, the vast majority of these denials can be reversed at internal appeal.

## Federal Appeal Rights

You have full internal appeal rights under ERISA §503 or ACA §2719, followed by independent external review if the internal appeal is denied. The external review window is generally within four months of the final internal denial — confirm the precise deadline from your denial letter. Expedited review is available when clinical urgency requires faster action.

## Appeal Process and Timeline

1. Request the full denial rationale and a copy of Aetna's applicable clinical policy bulletin for TAVR. 2. Identify the specific unmet criterion — Aetna must tell you exactly why it denied medical necessity. 3. File a Level 1 internal appeal with updated, criterion-targeted documentation. 4. Escalate to external review if the internal appeal is upheld.

## Documentation to Gather

• Diagnosis and severity confirmation: Recent echocardiogram and, if applicable, cardiac CT or catheterization reports establishing the severity of aortic stenosis. Ensure the report explicitly states the severity classification.
• Symptom burden: Clinical notes documenting symptoms (chest pain, syncope, heart failure symptoms) that confirm the patient is symptomatic — a key threshold in most coverage policies.
• Surgical risk assessment: Formal risk calculation and written recommendation from your cardiothoracic surgery team, confirming low surgical risk and the team's recommendation for TAVR.
• Anatomy documentation: Cardiac CT with explicit comment on valve anatomy, annular sizing, and vascular access confirming TAVR technical feasibility.
• Prescriber medical-necessity letter: A detailed letter from your interventional cardiologist and/or structural heart team explaining why TAVR meets Aetna's own stated criteria, citing specific chart facts.

## Criteria-Mapping Structure

Obtain Aetna's exact medical-necessity criteria from its clinical policy bulletin — available on Aetna's website or by request. Then build a table: left column lists each Aetna criterion verbatim; middle column states the corresponding fact from your records with the source document and date; right column flags any criterion that may need additional documentation. Submit this table with your appeal letter so the reviewer can confirm compliance without having to search through voluminous records.
