What This Guide Covers

This guide helps patients with Fabry disease and their healthcare providers navigate Humana's prior authorization process for Fabrazyme (agalsidase beta) in California. Whether you're dealing with an initial request or appealing a denial, we'll walk you through each step with specific forms, timelines, and scripts that work.

Fabrazyme is an enzyme replacement therapy that costs approximately $1,100 per 5-mg vial and $7,600 per 35-mg vial when paying cash. Most patients need this infusion every two weeks, making insurance coverage essential for accessing this life-changing treatment.

From our advocates: We've seen families spend months going back and forth with incomplete paperwork, only to get approved within days once they submitted the right genetic testing results and specialist letter. The key is front-loading all documentation rather than responding to requests piecemeal.

Before You Start: Verify Your Coverage

Step 1: Confirm Your Plan Type

Log into MyHumana to verify whether you have:

  • Medicare Advantage (Part C): Most common for Humana members
  • Medicare Part D: Prescription drug coverage
  • Commercial/Employer plan: Different rules may apply

Important: Fabrazyme is typically covered under Medicare Part B as an infusion drug (medical benefit) rather than Part D, using HCPCS code J0180.

Step 2: Check Network Status

Verify your prescriber is in-network and confirm which specialty pharmacy you'll use:

  • CenterWell Specialty Pharmacy (Humana-owned, preferred): 1-800-486-2668
  • CVS Specialty (network provider)
  • Accredo (network provider)

Use Humana's pharmacy finder to confirm current network status.
