Understanding Renewal Triggers

Most Blue Cross Blue Shield Michigan prior authorizations for specialty medications like Galafold expire after 12 months. However, renewal triggers can vary based on your specific plan and clinical circumstances.

Key Renewal Indicators

Start early if you notice:

  • Authorization expiration date approaching (check your approval letter)
  • Pharmacy notification about upcoming PA expiration
  • Changes in your kidney function (eGFR declining toward 30 mL/min/1.73m²)
  • New cardiac symptoms or progression
  • Insurance plan changes for the new year
Tip: Set a calendar reminder 90 days before your PA expires. This gives adequate time for lab work, specialist visits, and potential appeals if needed.

Signs You Should Start Immediately

Contact your specialist right away if:

  • Your eGFR has dropped below 45 mL/min/1.73m² (may affect eligibility)
  • You've experienced significant side effects
  • You're switching from enzyme replacement therapy to Galafold
  • Your insurance plan is changing carriers

Evidence Update Requirements

Successful Galafold renewal requires demonstrating continued medical necessity and appropriate response to therapy. Blue Cross Blue Shield Michigan typically requires updated clinical evidence within the past 3-6 months.

Required Laboratory Tests

Test Purpose Frequency Normal Response
Alpha-galactosidase A activity Enzyme function monitoring Annually Stable or improved activity
Lyso-Gb3 levels Disease biomarker Annually Stable or decreasing
Serum creatinine/eGFR Kidney function Every 3-6 months Stable function (eGFR ≥30)
Urinalysis with protein Kidney involvement Every 3-6 months Stable or improved proteinuria
Echocardiogram Cardiac assessment Annually Stable wall thickness, function

Clinical Response Documentation

Your specialist should document:

  • Symptom improvement: Pain levels, gastrointestinal symptoms, quality of life
  • Functional status: Exercise tolerance, daily activities
  • Adherence: Confirm you're taking Galafold every other day as prescribed
  • Tolerability: Any side effects and management strategies
Note: If your lyso-Gb3 levels have increased, your doctor should verify medication adherence and assess for disease progression before renewal submission.

Building Your Renewal Packet

A complete renewal packet significantly improves approval chances and reduces processing delays.

Must-Include Documents

Clinical Documentation:

  1. Updated specialist evaluation (within 3 months)
  2. Laboratory results (complete panel as listed above)
  3. Medication adherence records from specialty pharmacy
  4. Prior authorization renewal form (BCBSM-specific)

Supporting Evidence: 5. Treatment response summary comparing baseline to current status 6. Adverse event log (if applicable) 7. Quality of life assessment (patient-reported outcomes)

Letter of Medical Necessity Structure

Your specialist's renewal letter should follow this framework:

Paragraph 1: Patient identification and confirmed GLA variant amenability Paragraph 2: Current clinical status and objective improvements Paragraph 3: Laboratory trends and biomarker responses Paragraph 4: Continued medical necessity and treatment goals Paragraph 5: Risk of therapy interruption and alternative limitations

Clinician Corner: Include specific numerical improvements when possible (e.g., "Patient's exercise tolerance improved from 2 to 6 blocks walking distance" or "Lyso-Gb3 decreased from 45 to 32 ng/mL over 12 months").

When Coverage Lapses

Despite careful planning, coverage gaps can occur. Here's how to minimize therapy interruption:

Immediate Steps if Authorization Expires

  1. Contact Amicus Assist (1-877-4AMICUS) for potential bridge coverage
  2. File expedited appeal if renewal was denied
  3. Request emergency supply from specialty pharmacy
  4. Document medical urgency with your specialist

Bridge Coverage Options

Manufacturer Support: Amicus Therapeutics patient assistance programs may provide temporary medication access during coverage transitions.

Emergency Prescription: Some specialty pharmacies can provide a limited emergency supply while appeals are processed.

Important: Never stop Galafold abruptly without specialist guidance. Missing doses can affect treatment efficacy and disease progression.

Missed Dose Guidelines

If you miss a dose due to supply issues:

  • Within 12 hours: Take the missed dose
  • More than 12 hours late: Skip and resume at next scheduled day
  • Never double dose or take on consecutive days

The key is showing objective evidence that therapy interruption would harm the patient's condition."

FAQ

How long does BCBSM Galafold renewal take in Michigan? Standard processing is 14 business days for complete submissions. Incomplete packets may take 30+ days due to additional information requests.

What if my kidney function has declined below eGFR 30? Galafold is not recommended with severe renal impairment. Your specialist may need to transition you to enzyme replacement therapy and document this medical necessity.

Can I request expedited renewal review? Yes, if therapy interruption would seriously jeopardize your health. Your doctor must provide a letter documenting the urgency.

Does BCBSM require step therapy for Galafold renewals? Typically no for renewals if you're already responding well. However, new PA criteria could change annually—verify current requirements.

What if my specialist is no longer in-network? You may need a referral to an in-network metabolic specialist or request a network exception to continue with your current doctor.

How do I know if my GLA variant is still considered amenable? Amenability doesn't change, but verify your genetic testing is properly documented in your medical record for renewal submissions.
