What This Guide Covers

This comprehensive guide helps patients with mucopolysaccharidosis type I (MPS I) and their healthcare teams navigate Aetna CVS Health's prior authorization process for Aldurazyme (laronidase) in Texas. Whether you're facing an initial request, denial appeal, or annual renewal, you'll find the specific forms, timelines, and strategies needed for approval.

Aldurazyme is the only FDA-approved enzyme replacement therapy for MPS I, making it essential for patients with this rare genetic disorder. At approximately $1,113 per vial (manufacturer WAC pricing as of January 2025), proper insurance coverage is critical for accessing this life-changing treatment.

Before You Start: Verify Your Coverage

Step 1: Confirm Your Plan Type

Call Aetna member services at 1-800-872-3862 with your member ID to verify:

  • Whether you have commercial, Medicare Advantage, or Medicaid coverage
  • If Aldurazyme falls under medical benefit (typical) or pharmacy benefit
  • Your deductible, copay, and out-of-pocket maximum
  • Whether CVS Specialty Pharmacy is required for dispensing

Step 2: Check Formulary Status

Aldurazyme appears on Aetna's 2025 precertification list as a Tier 4/5 specialty drug requiring prior authorization. It's typically covered under the medical benefit for infusion therapies rather than as a traditional pharmacy formulary drug.

Note: Texas residents with employer-sponsored ERISA plans follow federal appeal rules, while state-regulated plans follow Texas Department of Insurance guidelines.
