From Our Advocates

"We've seen Fabrazyme appeals succeed when families provide comprehensive genetic testing results and a detailed specialist letter explaining why enzyme replacement is medically necessary. The key is demonstrating that the diagnosis meets Florida Blue's specific criteria and that alternative treatments aren't appropriate for the patient's genetic variant. Most well-documented cases resolve at the internal appeal level."

Renewal Requirements

When to Reauthorize

Fabrazyme typically requires reauthorization every 12 months, though this varies by plan.

Continuation Criteria

For reauthorization approval, you must meet all of the following:

  1. Prior approval history: Authorization within past 2 years OR paid claim within 90 days from previous plan
  2. Ongoing specialist care: Continued prescription by qualified Fabry specialist
  3. Clinical benefit: No evidence of toxicity or treatment failure
  4. Continued medical necessity: Still meets Fabry disease criteria

What Changes Might Affect Renewal

  • New alternative therapies: Florida Blue may require consideration of newly approved options
  • Updated guidelines: Medical policy changes could affect criteria
  • Clinical status changes: Significant improvement or decline might impact coverage

Common Problems and Solutions

"Prior Authorization Pending Too Long"

If no response within timeline:

  • Call Florida Blue at number on ID card

"Wrong Specialty Pharmacy Used"

Solution: Ensure your provider orders Fabrazyme through Florida Blue's approved specialty pharmacy network (Accredo or CVS/Caremark).
