Policy Overview: How BCBS Virginia Covers Naglazyme

Anthem Blue Cross Blue Shield Virginia, which covers approximately 43% of the commercial insurance market in the state, requires prior authorization for Naglazyme (galsulfase) across all plan types—HMO, PPO, and Medicaid managed care products. As of July 2024, medications billed under the medical benefit require enhanced clinical necessity review, reflecting stricter oversight of high-cost specialty therapies.

Plan Coverage Scope:

  • Commercial HMO and PPO plans
  • Virginia Medicaid managed care (through Anthem HealthKeepers Plus)
  • Self-funded employer plans using Anthem networks
  • Coverage varies for out-of-state Blues plans (verify with member services)

The drug is classified as a specialty medication requiring dispensation through Anthem's designated specialty pharmacy network, with specific site-of-care requirements for infusion administration.

Indication Requirements: Proving Medical Necessity

Naglazyme coverage hinges on documenting a confirmed diagnosis of Mucopolysaccharidosis VI (Maroteaux-Lamy syndrome) and demonstrating functional impairment that warrants enzyme replacement therapy.

Core Diagnostic Requirements:

  • Enzyme Assay: Documented deficiency of arylsulfatase B (ARSB) enzyme activity in leukocytes or fibroblasts
  • Genetic Testing: Molecular confirmation of pathogenic mutations in the ARSB gene
  • Clinical Manifestations: Evidence of MPS VI symptoms including skeletal abnormalities, corneal clouding, or cardiopulmonary involvement
  • ICD-10 Code: E76.29 (Other mucopolysaccharidoses)

The FDA-approved indication specifically covers patients with MPS VI who demonstrate clinical evidence of disease progression and functional limitations.

Step Therapy & Exceptions

Unlike many specialty medications, Naglazyme typically doesn't require step therapy since it's the only FDA-approved enzyme replacement therapy for MPS VI. However, BCBS Virginia may require documentation that supportive care measures have been optimized.

Documentation to Include:

  • Current supportive therapies (physical therapy, orthopedic interventions, pulmonary care)
  • Rationale for why enzyme replacement is necessary beyond supportive care
  • Evidence that delay would result in irreversible disease progression

Required Diagnostics & Documentation

BCBS Virginia's prior authorization process demands comprehensive clinical documentation submitted through the Availity Essentials portal.

Baseline Functional Assessments

6-Minute Walk Test (6MWT):

Stair Climbing Assessment:

Laboratory Requirements

  • Urinary glycosaminoglycan (GAG) levels
  • Liver function tests (baseline and monitoring)
  • Echocardiogram or pulmonary function tests if cardiac/pulmonary involvement

Site of Care & Specialty Pharmacy Requirements

BCBS plans, following models like Blue Shield of California, typically require Naglazyme infusions at preferred sites of service to control costs while ensuring safety.

Preferred Sites:

  • Home infusion (when clinically appropriate)
  • Physician office-based infusion centers
  • Independent ambulatory infusion centers

Hospital Outpatient Requires Special Authorization:

  • History of severe infusion reactions (anaphylaxis, seizures)
  • Medical complexity requiring enhanced monitoring
  • Initiation or re-initiation after 6+ month gap
  • Physical/cognitive impairment without home caregiver support

Billing Requirements:

  • HCPCS Code: J1458 (per 1 mg of galsulfase)
  • NDC numbers must match approved specialty pharmacy dispensation
  • Site-of-care documentation required for reimbursement
Clinician Corner: Medical Necessity Letter Checklist

Your prior authorization letter should include: (1) Confirmed MPS VI diagnosis with enzyme/genetic testing results, (2) Baseline functional assessments (6MWT, stair climbing), (3) Clinical rationale citing FDA labeling and treatment guidelines, (4) Weight-based dosing calculation (1 mg/kg weekly), (5) Monitoring plan for efficacy and safety, (6) Expected treatment duration and reassessment intervals.

Evidence to Support Medical Necessity

When documenting medical necessity, reference authoritative sources that payers recognize:

Primary Evidence Sources:

  • FDA prescribing information for approved indications
  • Clinical trial data showing functional improvements
  • Professional society guidelines (when available)
  • Peer-reviewed literature supporting enzyme replacement therapy in MPS VI

Key Clinical Data Points:

  • Naglazyme demonstrated statistically significant improvements in 6MWT and stair climbing in pivotal trials
  • Treatment effects sustained over 72+ weeks of therapy
  • Safety profile established in clinical studies with manageable infusion reactions

Appeals Process in Virginia

If BCBS Virginia denies your Naglazyme prior authorization, Virginia's robust external review process provides a pathway to independent medical review.

Internal Appeals (First Step)

  • Timeline: Submit within 180 days of denial notice
  • Process: Contact BCBS member services or submit through provider portal
  • Documentation: Include additional clinical evidence, peer-reviewed literature, specialist consultation

External Review Through Virginia SCC

After exhausting internal appeals, Virginia's State Corporation Commission Bureau of Insurance provides independent review:

Process Overview:

  • Eligibility: Virginia-issued commercial plans; denials based on medical necessity
  • Timeline: Request within 120 days of final internal denial
  • Forms: Submit SCC Form 216-A with supporting documentation

  • Contact: SCC External Review line at 1-877-310-6560

Success Factors:

  • Comprehensive clinical documentation
  • Independent specialist opinions
  • Evidence-based medical literature
  • Clear demonstration of functional impairment and treatment need

Common Denial Reasons & Solutions

FAQ

How long does BCBS Virginia prior authorization take for Naglazyme? Standard prior authorization decisions are typically made within 72 hours for urgent requests and 15 days for standard requests. Complex cases requiring additional clinical review may take longer.

What if Naglazyme isn't on my BCBS formulary? Submit a formulary exception request with comprehensive medical necessity documentation. Include evidence that no formulary alternatives exist for MPS VI treatment.

Can I request expedited appeals in Virginia? Yes, expedited external reviews are available if your physician certifies that waiting could seriously jeopardize your health. Decisions are made within 72 hours.

Does step therapy apply if I've tried treatments in another state? Document all prior therapies regardless of location. BCBS should recognize appropriate prior trials when supported by medical records.

What happens if my appeal is denied? Virginia's external review decision is binding on the insurer. If unsuccessful, consult with healthcare attorneys about potential legal options or explore alternative funding sources.

How often do I need reauthorization for Naglazyme? Most plans require reauthorization every 6-12 months with updated functional assessments and clinical response documentation.

From Our Advocates: We've seen families succeed with Naglazyme appeals by focusing on objective functional measures rather than just diagnostic criteria. One family's case was approved after providing detailed 6-minute walk test results showing significant impairment, combined with a specialist letter explaining how enzyme replacement therapy was the only treatment option to prevent further functional decline. The key was presenting quantitative evidence that clearly demonstrated medical necessity.
