Answer Box: Renewing Naglazyme (Galsulfase) Coverage with Aetna (CVS Health) in Florida

Aetna requires annual prior authorization renewal for Naglazyme (galsulfase) with documented clinical response to therapy. Start your renewal 60-90 days before expiration to avoid treatment gaps. Key requirements include: (1) confirmation of clinically positive response showing improvement, stabilization, or slowing of MPS VI progression, (2) medical chart documentation from within the past 12 months, and (3) objective evidence like 6-minute walk test improvements or reduced urinary GAG levels. Submit through Aetna's provider portal or complete their Naglazyme precertification form. If denied, you have 180 days to appeal through Florida's internal and external review process.

Renewal Triggers: When to Start

Start your Naglazyme renewal process 60-90 days before your current authorization expires. Aetna typically provides initial and renewal authorizations for up to 12 months, requiring annual reauthorization.

Early Warning Signs to Begin Renewal:

  • Authorization expires within 90 days
  • You've received 6+ months of continuous therapy
  • Recent lab work shows treatment response
  • Upcoming specialist appointments scheduled
Tip: Set calendar reminders 90 days before your authorization expiration date. Treatment gaps can lead to rapid clinical deterioration in MPS VI patients.

Evidence Update Requirements

Aetna's renewal criteria focus on documented clinical response to therapy. Your renewal must demonstrate that you've experienced improvement, stabilization, or slowing of disease progression.

Required Clinical Evidence:

Evidence Type What's Required How Often
Functional Assessment 6-minute walk test (6MWT) showing improvement or stabilization Every 6-12 months
Stair Climbing Test 3-minute stair climb showing maintained or improved capacity Every 6-12 months
Urinary GAG Levels Reduction or stabilization compared to baseline Every 6 months
Clinical Visit Notes Documentation of patient seen within past 12 months Annual minimum
Adverse Event Monitoring Record of infusion reactions and management Ongoing

Response Monitoring Parameters:

  • Respiratory function: Spirometry (FVC, FEV1), oxygen saturation
  • Cardiac assessment: Echocardiogram showing stable or improved left ventricular function
  • Mobility measures: Joint range of motion, endurance testing
  • Quality of life: Sleep studies, pain assessments

Renewal Packet Essentials

Your renewal submission must include comprehensive documentation proving continued medical necessity.

Core Documents Checklist:

  • ✅ Completed Aetna Naglazyme precertification form
  • ✅ Recent clinical visit notes (within 12 months)
  • ✅ Functional assessment results (6MWT, stair climbing)
  • ✅ Laboratory reports (urinary GAGs, baseline comparisons)
  • ✅ Specialist letter confirming clinical response
  • ✅ Infusion center documentation of treatment adherence

Medical Necessity Letter Structure:

Your physician's letter should address:

  1. Current clinical status compared to pre-treatment baseline
  2. Objective improvements in functional capacity or biomarkers
  3. Treatment adherence and infusion tolerance
  4. Risk of discontinuation citing published evidence of clinical decline
  5. Monitoring plan for continued assessment
Clinician Corner: Include specific metrics like "6MWT improved from 180m to 320m over 12 months" rather than general statements about "clinical improvement."

Timeline and Decision Windows

Understanding Aetna's decision timelines helps you plan effectively and avoid treatment interruptions.

Standard Timeline:

  • Submission to decision: 30-45 days for standard reviews
  • Expedited reviews: ≤72 hours for urgent medical situations
  • Appeals process: 30 days for internal appeals, additional time for external review

Key Dates to Track:

  1. 90 days before expiration: Begin gathering renewal documents
  2. 60 days before expiration: Submit complete renewal packet
  3. 30 days before expiration: Follow up if no decision received
  4. 15 days before expiration: Request expedited review if needed
  5. Expiration date: File appeal if denied

If Coverage Lapses

Treatment interruption can cause rapid clinical deterioration in MPS VI patients. If your coverage lapses, take immediate action to minimize therapy gaps.

Emergency Supply Options:

  • Manufacturer assistance: Contact BioMarin RareConnections at 1-800-NAGLAZYME for emergency supply programs
  • Specialty pharmacy support: Work with CVS Specialty or Accredo to identify temporary coverage options
  • Hospital compassionate use: Request emergency vials through your infusion center's compassionate use protocols

Bridge Therapy Considerations:

No standardized bridging therapy exists for Naglazyme gaps. Focus on:

  • Maintaining supportive care (respiratory, cardiac monitoring)
  • Resuming therapy as quickly as possible
  • Baseline re-evaluation before restarting treatment
From our advocates: "One family avoided a 3-week treatment gap by immediately contacting BioMarin's patient assistance program when their renewal was initially denied. The manufacturer provided temporary supply while the appeal was processed, preventing potential clinical deterioration."

Annual Plan Changes to Monitor

Stay informed about changes that could affect your Naglazyme coverage each plan year.

What to Verify Annually:

  • Formulary status: Confirm Naglazyme remains covered
  • Tier placement: Check if copay/coinsurance amounts changed
  • Prior authorization requirements: Review any new criteria
  • Preferred infusion sites: Verify your infusion center remains in-network
  • Specialty pharmacy network: Confirm CVS Specialty or alternative remains preferred

Plan Design Changes to Watch:

  • Step therapy requirements for new patients
  • Quantity limits or dosing restrictions
  • Site-of-care requirements (hospital vs. outpatient infusion)
  • Age-related coverage limitations
