The Requirements Checklist to Get Naglazyme (galsulfase) Covered by Humana in Virginia

Answer Box: Getting Naglazyme (galsulfase) Covered by Humana in Virginia

Naglazyme (galsulfase) requires prior authorization from Humana with standard reviews taking up to 30 days and expedited reviews within 72 hours if physician-certified as urgent. Virginia patients have strong appeal rights through the State Corporation Commission's external review process if denied.

Fastest path to approval:

  1. Confirm MPS VI diagnosis with enzyme assay (arylsulfatase B deficiency) and genetic testing
  2. Submit PA via Humana's provider portal or fax to 877-486-2621
  3. Include baseline functional assessments (6-minute walk test, stair climbing capacity)

First step today: Gather insurance card, MPS VI diagnostic results, and contact your prescriber to initiate the PA process.

Who Should Use This Guide

This comprehensive checklist is designed for Virginia patients with MPS VI (Maroteaux-Lamy syndrome) and their healthcare teams seeking Humana coverage for Naglazyme (galsulfase) enzyme replacement therapy. You'll also find this useful if you've received a denial and need to understand the appeal process.

Expected outcome: Following this guide systematically increases your chances of initial approval and provides a clear roadmap for appeals if needed. Virginia's external review process has helped many patients overturn wrongful denials for specialty medications.


Member & Plan Basics

Coverage Verification

Before starting the PA process, confirm these essential details:

  • Active Humana coverage with current member ID
  • Plan type: Most commonly Medicare Advantage/Part D in Virginia
  • Formulary status: Naglazyme may be non-formulary, requiring exception requests
  • Deductible status: High-cost specialty drugs may apply to deductible
Tip: Call Humana member services at 1-800-457-4708 to verify your specific plan's coverage details and PA requirements.

Authorization Requirements

Humana requires prior authorization for high-cost enzyme replacement therapies like Naglazyme to confirm medical necessity. Filling without approval risks full patient cost responsibility, which can exceed $100,000 annually.


Clinical Criteria Requirements

Primary Indication

ICD-10 Code E76.29 (Other mucopolysaccharidoses) must be supported by:

Diagnostic Requirement Documentation Needed Source
Enzyme Assay Arylsulfatase B activity <10% normal in leukocytes/fibroblasts Naglazyme diagnostic criteria
Genetic Testing Pathogenic ARSB gene mutations (biallelic) MPS VI genetic testing
Clinical Features Corneal clouding, skeletal dysplasia, hepatosplenomegaly FDA label requirements

Baseline Functional Assessments

Required before treatment initiation:

  • 6-minute walk test (6MWT): Measures endurance capacity
  • 3-minute stair climb test: Counts stairs ascended
  • Pulmonary function tests: FEV1, FVC measurements
  • Urinary GAG levels: Elevated dermatan sulfate and chondroitin sulfate
Note: These baseline measurements are critical for demonstrating treatment response during renewal reviews.

Dosing Requirements

  • Standard dose: 1 mg/kg IV weekly
  • Administration: Hospital or infusion center setting
  • HCPCS code: J1458 (1 unit = 1 mg)

Coding & Billing Information

Essential Codes

Code Type Code Description
ICD-10 E76.29 Other mucopolysaccharidoses (MPS VI)
HCPCS J1458 Injection, galsulfase, 1 mg
NDC 68135-0020-01 Naglazyme 5 mg/5 mL vial

Billing Units

Calculate units based on patient weight: 30 kg patient = 30 units of J1458 per weekly infusion.

Provider Letter of Medical Necessity

Your prescriber's letter should include:

Clinical History:

  • MPS VI diagnosis confirmation with enzyme/genetic results
  • Symptom progression and functional limitations
  • Prior treatments attempted (if applicable)

Treatment Rationale:

  • Why Naglazyme is medically necessary
  • Expected clinical benefits
  • Monitoring plan with objective measures

Supporting Evidence:

  • FDA labeling for MPS VI indication

  • Treatment goals and success metrics

Required Attachments

Submission Process

Submission Methods

  1. Online: Humana Provider Portal (preferred)
  2. Fax: 877-486-2621
  3. Phone: 866-421-5663 (Mon-Fri, 7am-7pm CT)

Form Requirements

Use Humana's Medicare PA forms available through the Prior Authorization Search Tool. Search "Naglazyme" or "J1458" for drug-specific requirements.

Common Rejection Causes

  • Incomplete diagnostic documentation
  • Missing baseline functional assessments
  • Incorrect ICD-10 coding
  • Prescriber not recognized as appropriate specialist

Specialty Pharmacy Coordination

Many Humana plans require specialty pharmacy dispensing for Naglazyme. Your prescriber will need to:

  1. Select preferred vendor from Humana's network
  2. Complete transfer paperwork with patient demographics and insurance information
  3. Coordinate delivery to infusion site
  4. Verify receipt and proper storage before administration
Tip: Establish this coordination early in the PA process to avoid delays once approval is received.

Common Denial Prevention Tips

Five Critical Pitfalls to Avoid

  1. Insufficient diagnostic proof: Ensure both enzyme assay AND genetic testing results are included
  2. Missing baseline assessments: 6MWT and stair climb tests are typically required
  3. Inappropriate prescriber: Must be genetics, endocrinology, or metabolic specialist
  4. Incomplete dosing justification: Include patient weight and mg/kg calculation
  5. Poor clinical narrative: Letter must clearly link MPS VI symptoms to treatment need

Appeals Process in Virginia

If your initial PA is denied, Virginia provides robust appeal rights through the State Corporation Commission Bureau of Insurance.

Internal Appeals (Humana)

  • Deadline: 65 days from denial notice
  • Timeline: 30 days for standard review, 72 hours for expedited
