Plan Types & Implications

Humana operates primarily Medicare Advantage (Part C) and Medicare Part D plans in New York, with some commercial employer-sponsored options. For Opfolda (miglustat), the key distinctions are:

  • Medicare Advantage: Includes both medical and prescription coverage; specialty drugs like Opfolda fall under the medical benefit when administered in clinical settings
  • Part D Only: Standalone prescription coverage; Opfolda would be covered as a specialty pharmacy benefit
  • Network Requirements: Most Humana plans require you to use in-network providers and CenterWell Specialty Pharmacy for specialty medications
Note: Opfolda is only effective when used with Pombiliti (cipaglucosidase alfa), so both medications must be coordinated through your treatment team.

Formulary Status & Tier Placement

Opfolda (miglustat) is covered on Humana's 2024 formulary but with significant restrictions:

Coverage Detail Status Source
Formulary Tier Tier 5 (Specialty Drugs) Humana Drug Lists
Prior Authorization Required Humana Formulary
Step Therapy May apply (verify with plan) Plan-specific
Quantity Limits Typically "30 for 30 days" Standard specialty limits

Alternative agents that may be preferred include other enzyme replacement therapies like Nexviazyme or Lumizyme, though these treat the same condition through different mechanisms.

Prior Authorization Requirements

Required Documentation Checklist

Your prescriber must submit a comprehensive prior authorization package including:

  • Completed PA form via CoverMyMeds or fax to 877-486-2621
  • Clinical diagnosis with ICD-10 codes for late-onset Pompe disease
  • Patient eligibility: Age ≥18 years, weight ≥40 kg
  • Current therapy status: Documentation that patient is not adequately improving on current enzyme replacement therapy
  • Combination therapy plan: Prescription for both Opfolda and Pombiliti with proper timing (Opfolda taken 1 hour before each Pombiliti infusion)
  • Dosing rationale: Weight-based dosing (195 mg for 40-<50 kg; 260 mg for ≥50 kg)
  • Supporting labs/tests: Enzyme assays, genetic testing, or other diagnostic confirmation

Medical Necessity Criteria

Humana typically approves Opfolda when the following criteria are met:

  1. Confirmed diagnosis of late-onset Pompe disease
  2. Inadequate response to current enzyme replacement therapy, documented over at least 6 months
  3. Appropriate candidate for combination therapy (no contraindications)
  4. Prescriber expertise (preferably from a specialist familiar with lysosomal storage disorders)
Clinician Corner: Include specific enzyme levels, functional assessments (6-minute walk test, pulmonary function), and quality of life measures in your medical necessity letter. Reference FDA labeling and published clinical trial data.

Specialty Pharmacy Network

All Opfolda prescriptions must be routed through CenterWell Specialty Pharmacy, Humana's preferred specialty partner. Here's the process:

Prescription Routing Steps

  1. E-prescribe directly to CenterWell Specialty Pharmacy
  2. Include all NCPDP fields required for specialty claims
  3. Coordinate with Pombiliti prescriptions for proper timing
  4. Patient enrollment in CenterWell's patient support program
Tip: CenterWell provides medication synchronization services to ensure both Opfolda and Pombiliti arrive together for each treatment cycle.

Cost-Share Structure

As a Tier 5 specialty drug, Opfolda carries significant cost-sharing:

  • Deductible: May apply depending on your specific plan
  • Coinsurance: Typically 25-33% for specialty tiers
  • Out-of-pocket maximum: Protects against catastrophic costs (2024 limit: $8,300 for Medicare Part D)

Potential Cost Assistance

  • Amicus Assist: Manufacturer's patient support program - verify eligibility at AmicusTherapeutics.com
  • Medicare Extra Help: Low-income subsidy program for Part D costs
  • State pharmaceutical assistance programs in New York
