How to Get Aldurazyme (Laronidase) Covered by Humana in Ohio: Coding, Appeals, and Authorization Guide

Quick Answer: Getting Aldurazyme (Laronidase) Covered by Humana in Ohio

Aldurazyme requires prior authorization from Humana with genetic confirmation of MPS I, baseline assessments, and specialist documentation. Fastest path: Submit complete PA request with ICD-10 code E76.01-E76.03, HCPCS J1931, genetic testing results, and baseline uGAG levels. If denied, you have 65 days to appeal internally, followed by automatic external review. Start today: Contact your MPS specialist to gather genetic testing results and baseline measurements, then submit via Humana's PA portal with complete medical records.

Coding Basics: Medical vs. Pharmacy Benefit

Aldurazyme (laronidase) typically falls under the medical benefit for Humana plans since it's administered via IV infusion in clinical settings. This affects both coding and authorization pathways:

Medical Benefit Path:

  • Requires HCPCS J-code billing (J1931)
  • Prior authorization through medical management
  • Claims submitted by infusion centers or hospitals
  • Uses medical deductible and coinsurance

Key Difference: Unlike oral medications processed through pharmacy benefits, Aldurazyme requires medical coding and facility-based administration, making proper HCPCS coding essential for coverage.

ICD-10 Mapping for MPS I

Accurate diagnosis coding is critical for Humana approval. Use these specific ICD-10 codes based on MPS I subtype:

MPS I Subtype ICD-10 Code Documentation Keywords
Hurler syndrome (severe) E76.01 Severe cognitive impairment, early onset, developmental delay
Hurler-Scheie syndrome (intermediate) E76.02 Intermediate severity, variable cognitive involvement
Scheie syndrome (attenuated) E76.03 Mild/attenuated, preserved intelligence, later onset
MPS I unspecified E76.0 Use only if subtype cannot be determined

Documentation Words That Support Coding:

  • "Genetic testing confirms IDUA gene mutations"
  • "Alpha-L-iduronidase enzyme deficiency"
  • "Elevated urinary glycosaminoglycans (uGAG)"
  • "Dysostosis multiplex on imaging"
  • "Progressive multi-organ involvement"
Tip: Always specify the MPS I subtype in clinical documentation. Generic coding (E76.0) may trigger additional review requests from Humana.

Product Coding: HCPCS, NDC, and Units

HCPCS J-Code

J1931: Injection, laronidase, 0.1 mg

  • Each billable unit = 0.1 mg of laronidase
  • Standard dosing: 0.58 mg/kg weekly via IV infusion

NDC Code

58468-0070-01: Aldurazyme 2.9 mg/5 mL single-dose vial

Units Calculation

Formula: Total dose (mg) ÷ 0.1 mg = Billable units

Example: 50 kg patient receiving 0.58 mg/kg

  • Total dose: 50 kg × 0.58 mg/kg = 29 mg
  • Billable units: 29 mg ÷ 0.1 mg = 290 units

Humana Limits:

  • Maximum: 667 billable units every 7 days
  • Maximum: 92 vials every 28 days

Administration Coding

Use these CPT codes for infusion:

  • 96365: IV infusion, first hour
  • 96366: IV infusion, each additional hour

Clean Request Anatomy

A complete Humana PA request for Aldurazyme should include:

Patient Information Section

Patient: [Name, DOB, Humana ID]
Diagnosis: Mucopolysaccharidosis I, Hurler syndrome (E76.01)
Prescriber: [MPS specialist with credentials]

Clinical Documentation

  1. Genetic confirmation: IDUA gene testing results showing biallelic pathogenic mutations
  2. Enzyme testing: Alpha-L-iduronidase deficiency confirmation
  3. Baseline assessments:
    • Urinary glycosaminoglycan (uGAG) levels
    • For patients ≥6 years: FVC, 6-minute walk test, joint ROM
    • For patients 6 months-6 years: cardiac status, growth velocity
  4. Current clinical status: Multi-organ involvement documentation

Product Details

Drug: Aldurazyme (laronidase)
NDC: 58468-0070-01
HCPCS: J1931
Dose: 0.58 mg/kg IV weekly
Units per infusion: [calculated based on weight]
Duration: 12 months

Frequent Coding Pitfalls

Unit Conversion Errors

Wrong: Billing 29 units for a 29 mg dose Right: Billing 290 units (29 mg ÷ 0.1 mg per unit)

Mismatched Diagnosis Codes

Wrong: Using E76.0 (unspecified) when subtype is known Right: Use specific codes E76.01, E76.02, or E76.03

Missing Start Dates

Always include:

  • Treatment start date
  • Authorization period requested (typically 12 months)
  • Next review date

Incomplete Baseline Documentation

Common omissions:

  • uGAG levels not documented
  • Age-appropriate assessments missing
  • Genetic testing results not attached

Verification with Humana

Before submitting your PA request:

  1. Check formulary status: Verify Aldurazyme is on your specific Humana plan's formulary
  2. Confirm PA requirements: Review current Humana prior authorization lists (verify with source linked)
  3. Validate codes: Cross-check HCPCS J1931 is accepted for your plan type
  4. Review limits: Confirm current quantity limits haven't changed

Submission Methods:

  • Humana PA web portal (preferred)
  • Fax submission with tracking
  • Provider portal direct upload

Appeals Process in Ohio
