Set Your Goal: What Approval Requires

Getting Fabrazyme covered by Humana requires meeting specific medical criteria and following their prior authorization process. Here's what you and your doctor need to accomplish together:

Coverage Requirements at a Glance

Requirement What It Means Where to Find It
Confirmed Fabry Disease Pathogenic GLA gene mutation + enzyme deficiency Mayo Clinic genetic testing
Specialist Prescriber Geneticist, nephrologist, cardiologist, or metabolic specialist Provider directory on Humana.com
Prior Authorization Pre-approval required before dispensing Humana PA portal
Medical Necessity Letter Detailed clinical rationale from prescriber Template in Sanofi billing guide
Age Requirement ≥2 years old (FDA approval) FDA label via Drugs.com

Your partnership with your healthcare provider is crucial because Humana requires the prescriber to submit all prior authorization requests—pharmacies cannot initiate the process.


Visit Prep: Document Your Journey

Before your appointment, create a comprehensive timeline that will help your doctor build a strong case for medical necessity.

Symptom Timeline Checklist

Document these Fabry disease manifestations with dates:

  • Neurological: Burning pain in hands/feet (acroparesthesias), heat/cold intolerance
  • Kidney: Protein in urine, decreased kidney function, frequent urination
  • Heart: Chest pain, irregular heartbeat, shortness of breath
  • Skin: Dark red spots (angiokeratomas), decreased sweating
  • Gastrointestinal: Abdominal pain, diarrhea after eating
  • Other: Hearing loss, dizziness, fatigue

Treatment History Summary

Prepare a list of:

  1. Previous medications tried (including migalastat/Galafold if applicable)
  2. Outcomes and side effects experienced
  3. Functional impact on daily activities, work, or school
  4. Family history of Fabry disease or related symptoms
Tip: Bring a written summary to your appointment. This ensures nothing gets missed and helps your doctor document medical necessity accurately.

Evidence Kit: Labs and Medical Records

Your doctor will need specific diagnostic evidence to support the prior authorization request. Here's what to gather:

Required Diagnostic Tests

For Males:

  • Alpha-galactosidase A enzyme assay (blood test showing low/absent activity)
  • GLA gene sequencing for variant identification
  • Elevated globotriaosylsphingosine (Lyso-Gb3) levels if available

For Females:

  • GLA gene sequencing (primary diagnostic test—enzyme levels can be normal)
  • Lyso-Gb3 levels for additional support
  • Family history documentation if available

Supporting Clinical Evidence

  • Imaging results: Echocardiogram, kidney ultrasound, brain MRI
  • Lab values: Kidney function tests, urinalysis showing protein
  • Biopsy results: If tissue samples show Gb3 accumulation
  • Previous treatment records: Documentation of other therapies tried

The Mayo Clinic offers comprehensive Fabry testing that includes both enzyme assays and genetic sequencing.


Medical Necessity Letter Structure

Your doctor's medical necessity letter is the cornerstone of your prior authorization request. Here's what it should include:
