What Affects Vimizim Approval Timing

Several factors influence how quickly Humana processes your Vimizim (elosulfase alfa) prior authorization in Georgia:

Benefit Type & Plan Structure

  • Medicare Advantage: Vimizim is covered under Part B (medical benefit) with standard PA timelines of up to 14 days
  • Commercial plans: Follow similar timelines but may have plan-specific variations
  • Medicaid: Different pathway through Georgia Medicaid with separate approval criteria

Complexity of Clinical Criteria Vimizim requires extensive documentation due to its orphan drug status and high cost (~$700K-$2.1M annually). Humana's coverage policy mandates:

  • Confirmed MPS IVA (Morquio A syndrome) diagnosis
  • Deficient GALNS enzyme activity or biallelic pathogenic mutations
  • Baseline functional assessments
  • Specialist prescriber attestation

Documentation Completeness Incomplete submissions trigger additional information requests, adding 3-7 days to the process. The most common missing elements include genetic testing results, baseline 6-minute walk tests, and detailed prior therapy documentation.

Pre-Submission Preparation (0-2 Days)

Essential Documentation Checklist

Before your specialist submits the PA request, gather these required documents:

Document Type Specific Requirements Where to Obtain
Diagnosis Confirmation GALNS enzyme activity test results showing deficiency Genetics lab/specialist
Genetic Testing Biallelic pathogenic GALNS mutations (if enzyme test unavailable) Molecular genetics lab
Clinical Assessment ICD-10 E76.3, symptom documentation, imaging Specialist notes
Baseline Measures 6-minute walk test (≥30 meters), pulmonary function if applicable Clinic assessment
Insurance Verification Member ID, plan type, formulary status Humana provider portal

Coding & Billing Preparation

  • HCPCS Code: J1322 (injection, elosulfase alfa, 1 mg)
  • ICD-10: E76.219 (Mucopolysaccharidosis IVA)
  • NDC: 61771-100-01 (Vimizim 5mg/5mL vial)
Tip: Have your specialist's office verify Humana coverage and PA requirements using the prior authorization search tool before gathering documentation.
