Coverage Requirements & Eligibility

Humana's Medicare plans in Florida require prior authorization for Hemgenix, the $3.5 million gene therapy for adults with hemophilia B. Here's what you need to qualify:

Medical Necessity Criteria

Core Requirements:

  • Adults ≥18 years with severe/moderately severe hemophilia B
  • Factor IX activity ≤2% of normal
  • Currently on prophylactic Factor IX therapy OR history of serious bleeding episodes
  • No neutralizing antibodies (inhibitors) to Factor IX
  • Commitment to long-term monitoring plan

Documentation Must Include:

  • Baseline Factor IX activity levels (using consistent laboratory methods)
  • Complete bleeding history with dates and severity
  • Prior Factor IX prophylaxis records showing frequency and dosing
  • Liver function tests (ALT, AST, ALP, bilirubin)
  • Genetic confirmation of hemophilia B diagnosis
  • Treatment center certification for administration and monitoring
Note: Humana's Clinical Pharmacy Review (HCPR) evaluates each case individually. Missing documentation is the most common reason for initial denials.

Renewal Triggers: When to Start Early

Unlike traditional medications, Hemgenix is a one-time gene therapy—but insurance coverage may still require periodic renewals or re-evaluations, especially if you switch plans or if your insurer updates their policies.

Start Renewal Process When:

Immediate Triggers:

  • Plan change notification (switching Humana plans or leaving Humana)
  • Annual formulary updates (typically January 1st)
  • Coverage determination expires (some plans set time limits)
  • Loss of efficacy requiring additional Factor IX therapy

Proactive Timeline:

  • 90 days before plan year end: Check next year's formulary
  • 60 days before coverage expires: Begin renewal documentation
  • 30 days before deadline: Submit complete renewal packet

Warning Signs to Act Fast

  • Increased bleeding episodes (>2 in 6 months)
  • Factor IX levels dropping below therapeutic range
  • Need for prophylactic Factor IX ≥6 months per year
  • Liver enzyme elevations requiring intervention

Evidence Updates for Renewal

Your renewal documentation must demonstrate continued medical necessity and successful treatment outcomes.

Clinical Response Documentation

Factor IX Monitoring:

  • Current Factor IX activity levels (same lab/assay as baseline)
  • Trend analysis showing sustained therapeutic levels
  • Documentation of any level fluctuations and clinical impact

Bleeding Episode Tracking:

  • Complete log since last approval
  • Severity, location, and treatment required
  • Comparison to pre-Hemgenix bleeding patterns
  • Any emergency department visits or hospitalizations

Quality of Life Measures:

  • Joint health assessments
  • Physical activity improvements
  • Reduced prophylaxis burden
  • Patient-reported outcomes

Safety Monitoring Updates

Required Annual Assessments:

  • Liver enzymes (ALT, AST, ALP, total bilirubin)
  • Abdominal ultrasound results
  • Alpha-fetoprotein (AFP) levels
  • Any adverse events or complications
From Our Advocates: One patient's renewal was initially delayed because their treatment center submitted Factor IX levels from a different laboratory than baseline. Using consistent testing methods throughout monitoring strengthens your case and avoids unnecessary delays.

FAQ

How long does Humana prior authorization take for Hemgenix in Florida? Standard review takes up to 30 days, but expedited review is available within 72 hours if your doctor certifies urgent medical need.

What if Hemgenix isn't on my Humana formulary? You can request a formulary exception with supporting clinical documentation. Your hematologist must demonstrate medical necessity and lack of suitable alternatives.

Can I appeal if Humana requires step therapy first? Yes. If you've already failed Factor IX prophylaxis or have contraindications, your doctor can request a step therapy exception with proper documentation.

Does Florida have special protections for gene therapy coverage? Florida follows federal Medicare guidelines for gene therapy coverage, with additional state external review protections for denied claims.

How often do I need to renew Hemgenix coverage? Since it's a one-time therapy, renewal typically occurs only with plan changes or if coverage criteria are updated. Monitor your plan's annual formulary changes.

What happens if I switch from Humana to another insurer? The new insurer may require their own prior authorization process. Start early and coordinate with your treatment center to avoid coverage gaps.
