Medical Necessity Requirements

Cigna requires objective confirmation of Pompe disease and specialist oversight for Myozyme coverage. The drug is FDA-approved for both infantile-onset and late-onset Pompe disease.

Coverage at a Glance

Requirement What It Means Documentation Needed Source
Confirmed Diagnosis Pompe disease (ICD-10: E74.02) GAA enzyme assay + genetic testing FDA Label
Specialist Prescriber Metabolic, genetic, or neuromuscular specialist Prescriber credentials/board certification Cigna PA Policy
Prior Authorization Required for all plans Completed PA form + clinical documentation Cigna PA Forms
Dosing Compliance 20 mg/kg IV every 2 weeks Weight-based calculation documentation FDA Label

Step Therapy and Exceptions

Good news: Cigna does not require step therapy for Myozyme in confirmed Pompe disease cases. There are no clinically appropriate alternatives that patients must try first.

Medical Exception Pathways

If your plan initially requires step therapy (rare but possible), you can request an exception by documenting:

  • Lack of therapeutic alternatives for enzyme replacement in Pompe disease
  • Disease severity requiring immediate treatment
  • Contraindications to any suggested alternative therapies

Submit exception requests using Cigna's formulary exception process with specialist support.

Dosing and Quantity Limits

Cigna typically approves Myozyme at FDA-labeled dosing: 20 mg/kg IV every 2 weeks. Higher doses (40 mg/kg) require additional medical justification.

Standard Coverage Parameters

  • Maximum dose: 20 mg/kg every 14 days
  • Annual limit: 26 infusions per year
  • Vial calculations: Based on current weight and 50-mg vial size
  • Renewal requirements: Updated weight, clinical response documentation

Dose Adjustment Process

When weight changes require dose modifications:

  1. Document new weight with measurement date
  2. Recalculate total mg dose (weight × 20 mg/kg)
  3. Submit updated PA with revised vial count
  4. Provide clinical justification for any dose increases
Tip: Pediatric patients may need frequent dose adjustments as they grow. Plan for quarterly PA updates to avoid coverage gaps.

Required Diagnostic Documentation

Strong diagnostic documentation is crucial for Myozyme approval. Cigna requires objective proof of Pompe disease through laboratory testing.

Diagnostic Testing Pathway

First-Line Testing:

  • GAA enzyme activity via dried blood spot (DBS) or leukocyte assay
  • Elevated creatine/creatinine ratio (supportive evidence)
  • Urine glucotetrasaccharide (Glc4) levels

Confirmatory Testing:

  • GAA gene sequencing identifying pathogenic variants
  • Two disease-causing mutations (autosomal recessive inheritance)
  • Genetic counseling documentation

Documentation Checklist

  • Laboratory reports showing reduced GAA activity
  • Genetic test results with pathogenic variant identification
  • Clinical notes describing symptoms and disease progression
  • Specialist evaluation confirming Pompe diagnosis
  • Family history if applicable
  • Cardiac/pulmonary function studies showing disease impact

Specialty Pharmacy Requirements

Most Cigna plans require Myozyme to be dispensed through Accredo specialty pharmacy rather than retail pharmacies.

Accredo Enrollment Process

  1. Prescriber enrollment: Complete Accredo provider registration
  2. Patient enrollment: Create MyAccredoPatients account
  3. Benefits verification: Accredo confirms PA status and coverage
  4. Delivery coordination: Schedule shipments to infusion site

Site of Care Considerations

Approved Infusion Settings:

  • Hospital outpatient infusion centers
  • Specialty infusion clinics
  • Home infusion (with appropriate monitoring)

Network Requirements:

  • Verify infusion provider is in Cigna's medical network
  • Confirm site can receive Accredo deliveries
  • Ensure emergency management capabilities for infusion reactions
Important: Using out-of-network specialty pharmacies can result in denial or significantly higher out-of-pocket costs.

Evidence to Support Your Case

When submitting PA requests or appeals, include evidence-based support for Myozyme therapy in Pompe disease.

Key Clinical Guidelines

  • FDA prescribing information establishing efficacy and safety
  • Pompe disease management guidelines from specialty societies
  • Published clinical trials demonstrating improved outcomes
  • Real-world evidence of functional improvements

Medical Necessity Letter Components

Your specialist should address:

  1. Specific Pompe disease subtype (infantile vs. late-onset)
  2. Disease progression and current functional status
  3. Expected benefits of enzyme replacement therapy
  4. Lack of alternative treatments
  5. Monitoring plan for safety and efficacy
  6. Dosing rationale based on current weight
