Aetna's Policy Overview

Aetna (CVS Health) requires prior authorization for both Vyndaqel and Vyndamax across all plan types in Washington—including HMO, PPO, and Medicaid managed care plans. The medications are classified as specialty drugs on higher formulary tiers, typically requiring copays of $100-500+ per month depending on your specific benefit design.

Where to find official policies: Aetna publishes drug-specific coverage criteria in their Clinical Policy Bulletins and annual pharmacy drug guides. These documents outline exactly what Aetna considers "medically necessary" for tafamidis coverage.

Medical Necessity Requirements

Coverage at a Glance

Requirement What It Means Documentation Needed
ATTR-CM Diagnosis Confirmed transthyretin amyloid cardiomyopathy PYP scan grade 2-3 + AL exclusion labs
NYHA Class Heart failure class I-III only Clinical notes confirming functional status
Specialist Oversight Cardiology involvement required Prescription from or consultation with cardiologist
Prior Authorization Pre-approval mandatory Complete PA form with all supporting docs
Specialty Pharmacy CVS Specialty or approved network Must use designated specialty pharmacy

Core Eligibility Criteria

Aetna's medical necessity standards for tafamidis are strict but clearly defined:

1. Confirmed ATTR-CM Diagnosis

  • Diagnostic imaging: Technetium-99m PYP bone scintigraphy showing grade 2 or 3 myocardial uptake
  • AL amyloidosis exclusion: Negative serum/urine immunofixation and normal free light chain ratio
  • Genetic testing: Required to distinguish wild-type from hereditary ATTR-CM

2. Heart Failure Classification

  • Covered: NYHA functional class I, II, or III
  • Excluded: NYHA class IV patients are not eligible for coverage
  • Documentation: Clinical notes must clearly state current NYHA class

3. Specialist Requirements

  • Prescription must be from or in consultation with a cardiologist
  • Provider must demonstrate expertise in ATTR-CM management
  • Ongoing monitoring plan required

Step Therapy & Exceptions

Unlike many medications, tafamidis doesn't have traditional step therapy requirements since there's no generic equivalent. However, Aetna may require documentation that:

  • Standard heart failure medications are inappropriate due to ATTR-CM pathophysiology
  • Patient has specific contraindications to conventional therapies
  • Tafamidis is the only appropriate ATTR-targeted therapy

Medical Exception Pathway: If you have contraindications to standard HF treatments, your cardiologist should document these clearly in the prior authorization request, including specific reasons why conventional therapies won't address the underlying amyloid deposits.

Quantity Limits & Dosing

Aetna enforces strict quantity limits aligned with FDA-approved dosing:

  • Vyndamax: 30 capsules per 30 days (61 mg once daily)
  • Vyndaqel: 120 capsules per 30 days (four 20 mg capsules = 80 mg once daily)
  • No combination therapy: Cannot be used with other ATTR-specific treatments like acoramidis
  • Renewal requirements: Continued coverage requires documentation of clinical benefit every 6-12 months

Required Diagnostics

Essential Test Results

Your prior authorization must include recent results from:

Cardiac Imaging:

  • Echocardiogram or cardiac MRI showing features consistent with infiltrative cardiomyopathy
  • PYP scan results with grade 2 or 3 uptake (most critical requirement)

Laboratory Studies:

  • Serum and urine immunofixation electrophoresis (must be negative)
  • Serum free light chains with normal kappa/lambda ratio
  • Basic metabolic panel and liver function tests
  • NT-proBNP or BNP levels

Genetic Testing:

  • TTR gene sequencing results (required for all patients)
  • Family history documentation if hereditary variant identified
Tip: Ensure all diagnostic tests are recent (typically within 6 months) and clearly document the exclusion of AL amyloidosis, as this is a common reason for denial.

Specialty Pharmacy Requirements

Tafamidis is only available through Pfizer's VYNDA Network, which includes CVS Specialty Pharmacy. You cannot fill this prescription at regular retail pharmacies.

Network Requirements:

  • Must use an Aetna-contracted specialty pharmacy that's also in the VYNDA Network
  • CVS Specialty is typically the preferred option for Aetna members
  • Home delivery is standard; no retail pickup available

Enrollment Process:

  1. Your doctor submits the CVS Specialty Amyloidosis Enrollment Form
  2. CVS Specialty verifies insurance benefits and prior authorization
  3. Patient completes financial assistance applications if needed
  4. Medication is shipped directly to your home

Evidence Documentation

Medical Necessity Letter Checklist

Your cardiologist's letter should address each of these points:

Clinical Problem:

  • Patient's specific ATTR-CM variant (wild-type or hereditary)
  • Current NYHA functional class and symptoms
  • Impact on quality of life and prognosis

Diagnostic Evidence:

  • PYP scan interpretation and grade
  • AL amyloidosis exclusion methodology
  • Genetic testing results

Treatment Rationale:

  • Why tafamidis is medically necessary for this patient
  • Expected clinical benefits (reduced mortality, fewer hospitalizations)
  • Monitoring plan for assessing response

Guideline Support: Reference current evidence such as:

  • FDA prescribing information for approved indications
  • Heart failure society guidelines supporting ATTR-CM treatment
  • Published clinical trial data (ATTR-ACT study)

Washington-Specific Resources

Office of the Insurance Commissioner:

Key Advantage: Washington's external review process uses independent medical specialists who can override Aetna's denial even if it technically meets their policy criteria, provided the treatment is medically appropriate.

Note: The combination of internal appeals (44% success) and external review (27% additional success) means persistent patients have approximately a 58% cumulative chance of overturning denials.

Common Denial Reasons & Fixes

Denial Reason How to Overturn
"Not medically necessary" Submit detailed cardiologist letter addressing specific clinical need
"Experimental/investigational" Cite FDA approval and published clinical trial data
"Non-formulary drug" Request formulary exception with medical necessity documentation
"Insufficient diagnostic evidence" Provide complete PYP scan report and AL exclusion labs
"NYHA Class IV" Document current functional status if class has improved
"Missing specialist oversight" Include cardiology consultation notes and ongoing care plan

Costs & Patient Support

Annual Cost: Vyndamax typically costs around $260,000 per year without insurance. With Aetna coverage, your out-of-pocket costs depend on your specific plan's specialty drug benefits.

Financial Assistance Options:

  • Pfizer VyndaLink Program: Copay assistance and patient navigation services
  • Medicare Part D: 2025 redesign caps annual out-of-pocket costs at $2,000
  • State programs: Washington Apple Health (Medicaid) may provide additional coverage
  • Foundation grants: Organizations like the HealthWell Foundation offer assistance for qualifying patients
