Pre-Authorization Preparation

Before submitting your prior authorization, ensure you have complete diagnostic and clinical documentation. Humana requires both biochemical and genetic confirmation of Type 1 Gaucher disease.

Required Diagnostic Testing

Enzyme Deficiency Testing:

  • Beta-glucosidase leukocyte (BGL) test showing markedly reduced enzyme activity
  • Available from most commercial labs
  • Low enzyme activity confirms Gaucher disease diagnosis

Genetic Confirmation:

  • GBA1 gene mutation analysis identifying two pathogenic mutations
  • Full sequencing recommended (over 450 known mutations)
  • Single mutation indicates carrier status only

Clinical Documentation Checklist

✓ Diagnosis confirmation: Enzyme assay results and genetic testing
✓ ICD-10 codes: E75.22 (Gaucher disease)
✓ Clinical presentation: Organomegaly, cytopenias, bone involvement
✓ Specialist involvement: Hematologist or metabolic disease specialist
✓ Prior therapies: Documentation of any previous treatments tried
✓ Treatment plan: Proposed dosing (2.5-60 U/kg per FDA label)

Tip: The FDA label for Cerezyme recommends 2.5 units/kg IV three times weekly up to 60 units/kg every two weeks, individualized based on disease severity and patient response.

If You're Denied: The Appeals Process

Required Documentation:

  • Completed appeal form

North Carolina-Specific Appeals Rights

Important: Medicare Advantage members cannot use North Carolina's Smart NC external review system. Instead, follow federal Medicare appeals processes.

  • External Review through Smart NC: 120 days to request after final internal denial
  • Contact: Smart NC at 1-855-408-1212
  • Process: Independent Review Organization (IRO) decision within 45 days
  • Expedited: 72-hour decision for urgent cases

For Medicare Advantage Plans

Federal appeals process applies:

  1. Humana Reconsideration (internal appeal)
  2. Independent Review Entity (IRE) - usually MAXIMUS
  3. Administrative Law Judge (ALJ) hearing
  4. Medicare Appeals Council
  5. Federal court (if applicable)

Alternative Options and Cost Support

Other Enzyme Replacement Therapies

If Cerezyme is denied, consider these FDA-approved alternatives:

  • Elelyso (taliglucerase alfa): Often preferred by payers for lower cost
  • Vpriv (velaglucerase alfa): Similar efficacy profile to Cerezyme

Oral Substrate Reduction Therapy

Cerdelga (eliglustat): For eligible adults with Type 1 Gaucher disease who cannot receive IV therapy

Financial Assistance

  • Sanofi Patient Assistance: Copay support and free drug programs
  • National Gaucher Foundation: Grant assistance available
  • State pharmaceutical assistance programs: Check North Carolina eligibility
From Our Advocates: We've seen cases where initial Cerezyme denials were overturned after submitting more comprehensive genetic testing results and detailed clinical progression notes. The key is demonstrating clear medical necessity with complete documentation rather than rushing the initial submission.

Common Denial Reasons and Solutions

Insufficient diagnostic evidence Submit complete enzyme assay and genetic testing
Step therapy not completed Document contraindications or failures with preferred agents
Non-participating provider Transfer care to Humana network specialist
Dosing outside guidelines Justify with clinical evidence and specialist recommendation
