Set Your Goal: Understanding What Approval Requires

Amvuttra (vutrisiran) is a specialized RNA interference therapy that requires prior authorization from Aetna CVS Health due to its high cost (~$476,000 annually) and specific indications. Your success depends on demonstrating that you meet FDA-approved criteria for either:

  • hATTR polyneuropathy: Hereditary transthyretin amyloidosis with nerve damage
  • ATTR cardiomyopathy: Heart muscle disease caused by transthyretin protein deposits

Coverage Requirements at a Glance

Requirement hATTR Polyneuropathy ATTR Cardiomyopathy Documentation Needed
Diagnosis Genetic test + biopsy/imaging Echo + imaging + genetic test Lab reports, pathology
Specialist Neurologist Cardiologist Provider credentials
Disease Stage PND ≤IIIb or NIS+7 I-II NYHA I-III with HF evidence Clinical scores, notes
Prior Therapy Document failures/intolerance Standard HF therapy tried Treatment records

Your partnership with your doctor is crucial because Aetna requires specialist-attested medical necessity that goes far beyond a simple prescription request.

Visit Preparation: Gathering Your Medical History

Before meeting with your neurologist or cardiologist, compile a comprehensive timeline of your symptoms and treatments. This preparation will help your doctor craft a compelling prior authorization request.

Symptom Timeline Checklist

For Polyneuropathy (hATTR-PN):

  • □ When did numbness/tingling start and where?
  • □ How has weakness progressed (walking, grip strength)?
  • □ Autonomic symptoms (digestive issues, blood pressure changes)
  • □ Family history of similar symptoms or known TTR mutations

For Cardiomyopathy (ATTR-CM):

  • □ Heart failure symptoms (shortness of breath, swelling)
  • □ Exercise tolerance changes (stairs, walking distance)
  • □ Hospitalizations for heart problems
  • □ Response to standard heart failure medications

Treatment History Documentation

Create a detailed record of:

  1. Previous medications tried with dates, doses, and reasons for stopping
  2. Side effects experienced with specific examples
  3. Other specialists seen and their recommendations
  4. Diagnostic tests completed (genetic testing, biopsies, imaging)
Tip: Bring copies of your most recent lab results, genetic test reports, and imaging studies to your appointment. This saves time and ensures accuracy in your prior authorization submission.

Building Your Evidence Kit

Your doctor needs specific documentation to meet Aetna's medical necessity criteria. Help them gather this evidence by requesting copies of key documents.

Essential Documentation Checklist

Diagnostic Evidence:

  • □ TTR genetic testing results showing pathogenic variant
  • □ Tissue biopsy reports (if available) confirming amyloid deposits
  • □ Cardiac imaging (echo, MRI) showing typical ATTR patterns
  • □ Bone scintigraphy (Tc99-PYP scan) results

Clinical Assessment:

  • □ Neurological exam findings and scoring (mNIS+7, PND stage)
  • □ Cardiac function tests (ejection fraction, NT-proBNP)
  • □ Functional assessments (6-minute walk test, NYHA class)
  • □ Quality of life questionnaires

Treatment Documentation:

  • □ Records of failed therapies (patisiran, tafamidis, others)
  • □ Contraindications to alternative treatments
  • □ Current medication list and responses

Requesting Medical Records

When contacting your doctor's office for records, use this script:

"I'm working with Dr. [Name] to request prior authorization for Amvuttra from my insurance. Could you please provide copies of my [genetic testing results/cardiac imaging/neurological assessments] from [date range]? I need these for my insurance submission."

Medical Necessity Letter Structure

Your doctor's letter of medical necessity is the cornerstone of your prior authorization request. Here's how to help them structure it effectively:

Letter Template Components

1. Patient Identification & Diagnosis

  • Clear statement of FDA-approved indication
  • ICD-10 codes (E85.1 for hATTR, I43 for cardiomyopathy)
  • Genetic testing confirmation with specific TTR variant

2. Clinical Rationale

  • Current disease stage and functional impact
  • Progression despite standard care
  • Why Amvuttra is medically necessary now

3. Prior Treatment History

  • Specific medications tried with dates and outcomes
  • Side effects or contraindications to alternatives
  • Documentation of treatment failures

4. Monitoring Plan

  • Quarterly assessments planned
  • Vitamin A supplementation protocol
  • Safety monitoring schedule
From our advocates: We've seen the strongest approvals when doctors include specific functional measures (like "patient can no longer walk more than 50 feet without assistance, down from 200 feet six months ago") rather than general statements about disease progression. Numbers tell a compelling story.

Supporting Your Doctor's Preparation

Offer to help by:

  • Providing a chronological symptom diary with specific dates and impacts
  • Gathering family medical history including any known TTR mutations
  • Compiling treatment response summaries from your perspective as the patient

When Counterforce Health analyzes successful prior authorization requests, we consistently see that the most effective letters combine clinical objectivity with specific, measurable impacts on daily functioning.

Supporting Your Doctor's Peer-to-Peer Review

If your initial prior authorization is denied, Aetna offers peer-to-peer review where your doctor can discuss your case directly with an Aetna medical director.

How to Request Peer-to-Peer Review

Your doctor can request this by:

  1. Calling Aetna's provider line at the number on your insurance card
  2. Requesting "peer-to-peer discussion with medical director"
  3. Providing your member ID and denial reference number

Preparation Support You Can Provide

Before the Call:

  • Compile a one-page case summary with key dates and test results
  • List your availability windows in case the doctor needs to reach you
  • Prepare specific examples of functional decline

Key Points for Your Doctor to Emphasize:

  • FDA indication match: Clear alignment with approved uses
  • Specialist expertise: Board certification in neurology/cardiology
  • Treatment urgency: Risk of irreversible progression without treatment
  • Alternative failures: Specific reasons other options won't work

Sample Talking Points

"This patient has confirmed hATTR polyneuropathy with documented progression despite standard care. TTR genetic testing shows [specific variant], and functional assessments demonstrate worsening neuropathy scores. Without disease-modifying therapy, we expect continued irreversible nerve damage."

After Your Visit: Staying Organized

Once your doctor submits the prior authorization, staying organized helps you track progress and prepare for potential appeals.

Documentation System

Create a simple filing system:

  • Insurance folder: Denial letters, EOBs, member ID cards
  • Medical folder: Test results, doctor notes, treatment records
  • Correspondence folder: Emails, fax confirmations, appeal submissions

Portal Monitoring

Most patients can track their prior authorization status through:

  • Aetna member portal or mobile app
  • Provider office patient portal
  • CVS Caremark specialty pharmacy if applicable

Check these regularly and save screenshots of status updates.

Communication Log

Keep a simple log of:

  • Date and time of calls to Aetna
  • Representative names and reference numbers
  • Promised follow-up dates
  • Action items for you or your doctor

Respectful Persistence: Following Up Effectively

Aetna typically processes prior authorizations within 30 days, but complex cases may take longer. Here's how to follow up appropriately:

Follow-Up Timeline

Week 1-2: Allow initial processing time Week 3: Contact your doctor's office to confirm submission Week 4: If no response, call Aetna member services Week 5+: Consider expedited review if medically urgent

Effective Communication Scripts

When calling Aetna: "I'm calling to check the status of prior authorization request [reference number] for Amvuttra submitted by Dr. [Name] on [date]. Can you provide an update on the timeline for decision?"

When following up with your doctor: "I wanted to check if you've received any response from Aetna about my Amvuttra prior authorization. Is there anything additional they've requested that I can help gather?"

When to Escalate

Consider escalating if:

  • No response after 45 days (beyond standard timeline)
  • Requests for information that was already submitted
  • Your condition is worsening while waiting
