How Long Does It Take to Get Cerezyme (Imiglucerase) Approved by Humana in New York? Complete Timeline Guide

Answer Box: Getting Cerezyme Approved by Humana in New York

Timeline: 2-3 weeks total if all documentation is complete. Humana requires prior authorization with step therapy to Elelyso or Vpriv first, unless medically contraindicated. Fastest path: Have your prescriber submit a complete PA with enzyme/genetic testing, step therapy documentation, and medical necessity letter via Humana's electronic portal. Start today: Confirm your plan type (Part B vs Part D) and gather diagnostic records. New York residents have strong appeal rights through the Department of Financial Services if denied.

What Affects Your Approval Timeline

Several factors determine how quickly Humana approves Cerezyme (imiglucerase) for Gaucher disease in New York:

Benefit Type: Part B vs Part D Coverage

Cerezyme coverage depends on where you receive treatment:

  • Part B (Medical): Infused at a clinic or hospital; typically requires 30 days for standard PA decisions
  • Part D (Pharmacy): Home infusion through specialty pharmacy; 72-hour standard for drug determinations
Note: Most Humana Medicare Advantage plans in New York classify Cerezyme as a Part B drug requiring specialty pharmacy distribution through CenterWell.

Documentation Completeness

Humana's PA approval hinges on having complete clinical documentation upfront:

Required Documentation Purpose Timeline Impact
Enzyme testing (β-glucocerebrosidase <15% normal) Confirms Type 1 Gaucher diagnosis Missing: +7-14 days
Genetic testing (biallelic GBA1 variants) Alternative diagnostic confirmation Missing: +7-14 days
Step therapy documentation Shows trial/failure of Elelyso or Vpriv Missing: +14-30 days
Medical necessity letter Justifies Cerezyme over alternatives Missing: +7-10 days

Step Therapy Requirements

Humana requires step therapy to preferred enzyme replacement therapies (Elelyso or Vpriv) before approving Cerezyme, unless you have:

  • Documented failure or intolerance to preferred agents
  • Medical contraindication
  • Prior successful treatment with Cerezyme

Pre-Submission Preparation (0-2 Days)

Gather Essential Documentation

For patients: Collect these items before your prescriber submits the PA:

  • Insurance card and member ID
  • Complete medical records from your hematologist or Gaucher specialist
  • Lab results confirming enzyme deficiency or genetic testing
  • Documentation of any prior enzyme replacement therapy trials

For prescribers: Prepare a comprehensive submission including:

Diagnosis Confirmation Checklist

✓ Enzyme testing: β-glucocerebrosidase activity <15% of normal in leukocytes, fibroblasts, or dried blood spot
✓ Genetic testing: Biallelic pathogenic variants in GBA1 gene (if enzyme testing unavailable)
✓ Clinical manifestations: Document splenomegaly, anemia, thrombocytopenia, or bone disease
✓ ICD-10 codes: E75.22 (Gaucher disease) with appropriate specificity

Step Therapy Documentation

Document attempts with preferred agents:

  • Elelyso (taliglucerase alfa): Dates of treatment, dosing, clinical response, reasons for discontinuation
  • Vpriv (velaglucerase alfa): Same documentation as above
  • Medical necessity for Cerezyme: Specific clinical rationale why preferred agents are inappropriate
Clinician Corner: Your medical necessity letter should address: (1) confirmed Type 1 Gaucher diagnosis with enzyme/genetic testing, (2) specific clinical manifestations requiring ERT, (3) documented trial and clinical outcome with Elelyso/Vpriv or contraindication rationale, (4) dosing plan within FDA range (2.5-60 units/kg), and (5) monitoring plan with treatment goals.

Submission to Initial Review (1-5 Days)

Humana's Review Process

Once submitted, Humana follows federal Medicare timelines:

Standard Prior Authorization:

  • Part D drugs: 72 hours from complete submission
  • Part B drugs: Up to 30 calendar days (often faster with electronic submission)

Expedited Review (when delay could seriously jeopardize health):

  • Part D: Within 24 hours for urgent drug requests
  • Part B: Within 72 hours

What Reviewers Check First

Humana's clinical reviewers prioritize:

  1. Diagnosis verification: Confirmed Type 1 Gaucher disease
  2. Step therapy compliance: Evidence of preferred agent trial or valid exception
  3. Dosing appropriateness: Within FDA-approved range
  4. Site of care: Confirms benefit type (Part B vs Part D)

Common Delays

  • Incomplete enzyme testing: Missing specific enzyme activity values
  • Vague step therapy documentation: "Patient failed Elelyso" without clinical details
  • Missing specialist consultation: Some plans prefer Gaucher specialist involvement

Decision Window & Outcomes

Typical Approval Timeline

Based on Humana's 2025 commitments, expect:

Submission Type Decision Timeline Distribution Timeline Total Time
Complete electronic PA 1 business day (95% by 2026) 7-10 business days 2-3 weeks
Standard paper PA Up to 30 days 7-10 business days 4-6 weeks
Expedited request 24-72 hours 5-7 business days 1-2 weeks

After Approval: Specialty Pharmacy Distribution

Humana requires Cerezyme dispensing through CenterWell Specialty Pharmacy. Timeline after PA approval:

  • Initial fill: 7-10 business days (includes benefit verification and shipping coordination)
  • Refills: 5-7 business days
  • No retail pharmacy options: Must use designated specialty network
From Our Advocates: "We've seen the biggest time savings when prescribers submit complete electronic PAs with all step therapy documentation attached upfront. One patient's approval went from a typical 3-4 week process to just 8 days because the hematologist included detailed Elelyso trial notes and specific clinical rationale for switching to Cerezyme."
