Understanding Humana's Requirements

Myozyme (alglucosidase alfa) is a high-cost enzyme replacement therapy for Pompe disease that requires prior authorization across all Humana plans. The medication costs approximately $1,026 per 50-mg vial, making it one of the most expensive treatments in Humana's specialty drug portfolio.

Read Your Denial Letter

Your denial letter contains critical information that determines your next steps. Look for these key elements:

Denial Reason Codes

  • PA001: Prior authorization not obtained
  • STEP: Step therapy requirements not met
  • NFORM: Non-formulary drug (requires exception)
  • LIMIT: Quantity or frequency limits exceeded
  • MEDNE: Not medically necessary per plan criteria

Critical Deadlines

  • Internal Appeal: 60 days from denial date for Medicare Advantage
  • Expedited Appeal: Request immediately if health at risk
  • External Review: 127 days from final internal denial (Michigan-specific)
Tip: Humana's denial letters often include specific clinical criteria that weren't met. Use this information to strengthen your appeal by directly addressing each point.

Common Fixable Issues

Before filing a formal appeal, check if your denial stems from correctable administrative issues:

Denial Reason Quick Fix Action Required
Missing diagnosis code Billing correction Provider resubmits with correct ICD-10
Incomplete PA form Documentation gap Submit missing clinical notes or test results
Wrong specialty pharmacy Network issue Transfer prescription to Humana-preferred pharmacy
Dosing discrepancy Clinical clarification Provider letter explaining FDA-approved dosing
Step therapy not documented Prior treatment records Submit documentation of failed therapies

At Counterforce Health, we help patients and providers identify these common gaps and turn insurance denials into successful appeals. Our platform analyzes denial letters and creates targeted, evidence-backed responses that address each payer's specific requirements.

First-Level Internal Appeal

Required Documentation

Your internal appeal should include:

  1. Completed appeal form (available on Humana member portal)
  2. Medical necessity letter from prescribing physician
  3. Complete medical records showing Pompe disease diagnosis
  4. Genetic testing results confirming GAA gene mutations
  5. Enzyme activity test showing GAA deficiency
  6. Functional assessments (pulmonary function, muscle strength, 6-minute walk test)
  7. Documentation of disease progression or functional decline

Submission Methods

  • Online: Through Humana member portal (fastest)
  • Fax: 877-486-2621 (standard appeals fax line)
  • Mail: Address provided in your denial letter
  • Phone: Call member services to initiate verbal appeal

Timeline: Standard appeals receive decisions within 30 days; expedited appeals within 72 hours if urgent medical need is documented.

Peer-to-Peer Review Strategy

If your initial appeal is denied, request a peer-to-peer review where your doctor speaks directly with Humana's medical director.

Scheduling the Call

  • Provider initiates: Your doctor's office calls Humana provider services
  • Typical wait time: 24-48 hours to schedule
  • Call duration: Usually 10-15 minutes
  • Participants: Your doctor and Humana medical director

Key Talking Points for Your Doctor

  1. Confirmed Pompe diagnosis with genetic and enzyme testing
  2. Evidence of functional decline with specific measurements
  3. Failed or inappropriate alternatives (if step therapy applies)
  4. FDA approval and standard of care rationale
  5. Monitoring plan for treatment response
From Our Advocates: In our experience helping patients navigate Pompe disease appeals, peer-to-peer calls are most successful when the prescribing physician has current functional assessments and can cite specific declines in forced vital capacity or 6-minute walk distance. Medical directors respond well to objective, measurable data rather than general statements about disease progression.

Michigan External Review Process

If Humana denies your internal appeal, Michigan law gives you the right to an independent external review through the Department of Insurance and Financial Services (DIFS).

Timeline and Process

  • Deadline: 127 days from Humana's final internal denial
  • Standard Review: Decision within 60 days
  • Expedited Review: Decision within 72 hours (with physician letter stating urgent need)

Medical Necessity Letter Checklist

Your physician's medical necessity letter should address these specific criteria:

Clinical Documentation

  • Confirmed diagnosis: Genetic testing showing two pathogenic GAA gene variants
  • Enzyme deficiency: GAA activity <1% normal (infantile) or <40% normal (late-onset)
  • Functional impairment: Documented muscle weakness, respiratory dysfunction, or cardiac involvement

  • Dosing justification: 20 mg/kg every 2 weeks per FDA labeling
  • Site of care: Experienced infusion center due to anaphylaxis risk
  • Monitoring plan: Regular assessments of respiratory and motor function
