Renewal Triggers: When to Start Early

UnitedHealthcare typically approves Fabrazyme for 12-month periods, requiring annual reauthorization. However, several situations should prompt you to begin the renewal process earlier than the standard 30-day window:

Start 60-90 Days Early If:

  • Your initial approval required multiple appeals or peer-to-peer reviews
  • You've experienced treatment interruptions or adherence challenges
  • Your clinical status has changed significantly (new symptoms, organ involvement)
  • You're approaching the $2,000 annual out-of-pocket maximum under Medicare Part D
  • Your UnitedHealthcare plan is changing for the next year

Warning Signs to Watch:

  • Pharmacy notifications about "prior authorization expiring soon"
  • Changes in your formulary tier placement (check your 2025 plan documents)
  • New step therapy requirements appearing in plan updates
Note: UnitedHealthcare's 2025 formulary changes include new deductible requirements for specialty medications, which may affect your out-of-pocket costs even if coverage continues.

Evidence Update: What Documentation You'll Need

Your renewal submission must demonstrate continued medical necessity and treatment response. UnitedHealthcare's enzyme replacement therapy policy requires specific clinical evidence updated within the past 6-12 months.

Required Clinical Documentation:

Laboratory Evidence:

  • Plasma globotriaosylceramide (GL-3) levels showing normalization or improvement
  • Renal function tests: GFR, 24-hour urine protein, creatinine clearance
  • Complete blood count and comprehensive metabolic panel
  • Antibody testing results (anti-agalsidase beta IgG/IgE, neutralizing antibodies)

Clinical Assessment:

  • Physical exam findings and interval history
  • Cardiac function evaluation (echocardiogram or MRI if clinically indicated)
  • Pain scores and quality of life assessments
  • Growth and development documentation (for pediatric patients)

Treatment Response Documentation:

  • Evidence of disease stabilization or improvement
  • Medication adherence records (≥85% compliance required)
  • Adverse event monitoring and management
  • Any dose adjustments and clinical rationale

Adherence Requirements

UnitedHealthcare's policy specifically requires documentation of at least 85% adherence to Fabrazyme therapy. Consistently lower adherence over two months may trigger medical director review. Work with your specialty pharmacy to maintain detailed infusion records and document any missed doses with medical justification.

Renewal Packet: Must-Include Documents

Core Documents Checklist:

  • Completed UnitedHealthcare prior authorization form (current version)
  • Updated letter of medical necessity from your prescribing specialist
  • Recent laboratory results (within 6 months)
  • Clinical progress notes from past 6-12 months
  • Pharmacy fill history demonstrating adherence
  • Current insurance card and member ID

Letter of Medical Necessity Structure:

Your specialist should address these key points:

  1. Confirmed Fabry disease diagnosis with genetic or biochemical testing results
  2. Current clinical status and disease progression
  3. Treatment response with specific biomarker improvements
  4. Continued medical necessity despite any clinical changes
  5. Alternative therapy considerations and why Fabrazyme remains optimal
Clinician Corner: Reference UnitedHealthcare's enzyme replacement therapy policy directly in your letter. Include specific policy criteria the patient meets, such as "confirmed α-galactosidase A deficiency with clinical manifestations of Fabry disease" and cite the policy number for easy reviewer reference.

If Coverage Lapses: Bridge Options

Coverage gaps can occur even with careful planning. Here are your options if Fabrazyme approval lapses:

  1. Contact your prescribing physician to initiate emergency appeals process
  2. File expedited internal appeal with UnitedHealthcare if medical urgency exists
  3. Apply for manufacturer bridge therapy through Sanofi Patient Connection
  4. Document medical necessity for continued treatment without interruption

Sanofi Bridge Program:

Sanofi offers temporary supply assistance for patients experiencing coverage interruptions. To access:

  • Contact Sanofi Patient Connection directly
  • Provide documentation of coverage gap and medical necessity
  • Typical bridge supply: 30-60 days while appeals are processed
  • Requires valid prescription and proof of insurance denial

Emergency Appeal Process:

Michigan patients can request expedited external review through DIFS if treatment delay would cause serious harm. Your physician must provide a written statement that interrupting Fabrazyme could jeopardize your health.

When coverage gaps occur, platforms like Counterforce Health can help streamline the appeal process by automatically generating targeted, evidence-backed appeals that address your specific denial reasons and align with UnitedHealthcare's policy requirements.
