Patient Profile: Who Qualifies for Hemgenix

Hemgenix (etranacogene dezaparvovec) is FDA-approved for adults with severe or moderate hemophilia B who meet specific criteria. Here's what Aetna CVS Health requires in Florida:

Coverage at a Glance

Requirement What It Means Where to Find It Source
Prior Authorization Required for all plans Aetna provider portal Aetna PA List 2024

Age Requirement ≥18 years Patient records FDA Label

Typical Patient Profile

A 28-year-old man with severe hemophilia B (Factor IX activity 0.8%) who has been on prophylactic Factor IX concentrate for 8 years. Despite optimal dosing, he continues to experience 3-4 breakthrough bleeding episodes annually, affecting his work as a teacher. His treatment center has documented over 200 exposure days with current therapy showing inadequate bleed control.

Pre-Authorization Preparation

Step 1: Gather Required Documentation

Clinical Records (30-60 days before submission):

  • Confirmed hemophilia B diagnosis with genetic testing results
  • Factor IX activity level ≤2% (without replacement therapy)
  • Complete bleeding history with dates and severity
  • Infusion logs showing ≥150 exposure days to Factor IX prophylaxis
  • Documentation of treatment failure (breakthrough bleeding despite optimal prophylaxis)

Laboratory Requirements:

  • Negative inhibitor test (Bethesda assay <0.6 BU within 30 days)
  • Liver function tests (ALT, AST, alkaline phosphatase, bilirubin)
  • Complete blood count with platelet count ≥50,000/microL
  • Creatinine and hepatitis B/C, HIV screening
  • Hepatic imaging (ultrasound or elastography within 3 months)
Tip: Start gathering documentation 30 days early. Missing labs are the most common cause of PA delays.

What We'd Do Differently

Key Takeaways from Successful Cases:

  1. Start early: Begin documentation gathering 60 days before planned treatment
  2. Use specialized centers: Partner with established hemophilia treatment centers familiar with gene therapy PAs
  3. Complete submissions: Incomplete documentation causes 70% of delays
  4. Leverage support: Counterforce Health helps turn denials into targeted appeals with evidence-backed rebuttals
  5. Know your rights: Florida's external review process has overturned many specialty drug denials
From our advocates: "We've seen Hemgenix appeals succeed when providers submit comprehensive bleeding diaries alongside pharmacy records. One case was initially denied for 'insufficient exposure days' but approved on appeal when we provided detailed infusion logs from three different pharmacies that Aetna hadn't previously received. The key was demonstrating the complete treatment history."
