Blue Cross Blue Shield Virginia Policy Overview

Anthem Blue Cross Blue Shield Virginia, which serves about 43% of the commercial insurance market in the state, requires prior authorization for Elaprase (idursulfase) across all plan types—HMO, PPO, and POS. The policy applies to both pediatric and adult patients with Hunter syndrome (MPS II).

Key Policy Elements:

  • Prior authorization mandatory for all Elaprase prescriptions
  • Weight-based quantity limits strictly enforced
  • Enzymatic and genetic confirmation required
  • Infusion monitoring plan must be documented
  • Annual reauthorization based on clinical response

You can find the most current prior authorization requirements on Anthem's Virginia provider portal, which updates PA lists multiple times per year (typically March, May, July, and November).

Medical Necessity Requirements

Core Eligibility Criteria

Blue Cross Blue Shield Virginia considers Elaprase medically necessary when all of the following are met:

Diagnostic Requirements:

  • Confirmed diagnosis of Hunter syndrome (MPS II) with both:
    • Deficient iduronate-2-sulfatase (I2S) enzyme activity
    • Pathogenic variant in the IDS gene identified through genetic testing
  • Clinical symptoms consistent with MPS II (developmental delays, respiratory issues, hepatosplenomegaly, skeletal abnormalities)

Treatment Justification:

  • Patient is appropriate candidate for enzyme replacement therapy
  • No contraindications to IV infusion therapy
  • Established infusion monitoring and emergency response plan
Note: Unlike some other lysosomal storage disorders, there are no FDA-approved alternatives to Elaprase for Hunter syndrome, which strengthens the medical necessity case.

Step Therapy and Exceptions

Good news for Hunter syndrome patients: Blue Cross Blue Shield Virginia typically does not require step therapy for Elaprase because it's the only FDA-approved enzyme replacement therapy for MPS II. However, insurers may still require documentation that:

  • Conservative management alone is insufficient
  • Patient would benefit from enzyme replacement therapy
  • Family understands the lifelong nature of treatment

Medical Exception Pathways: If any step therapy requirements are imposed, exceptions can be granted for:

  • Contraindication to required first-line therapy
  • Previous trial and failure of required medication
  • Drug interaction concerns
  • Age-related considerations

Weight-Based Dosing and Quantity Limits

Strict Dosing Protocol

Elaprase dosing is strictly weight-based at 0.5 mg/kg once weekly. This cannot be exceeded and forms the basis for quantity limit approvals.

Dosing Calculation Steps:

  1. Use patient's most recent weight in kilograms
  2. Multiply weight by 0.5 mg/kg for total weekly dose
  3. Divide total dose by 2 mg/mL (concentration) for volume needed
  4. Divide volume by 3 mL/vial to determine vials required

Example: 40 kg patient = 20 mg weekly dose = 10 mL volume = 3.33 vials (round down, dispose unused)

Critical: Insurance will deny requests exceeding 0.5 mg/kg/week or lacking current weight documentation. Update weight measurements every 6-12 months for reauthorization.

Coverage at a Glance

Requirement What It Means Documentation Needed Source
Prior Authorization Required for all prescriptions PA form via Anthem portal Anthem PA Requirements
Enzymatic Testing I2S enzyme deficiency Laboratory report showing low/absent activity Duke Test Catalog
Genetic Confirmation IDS gene mutation Molecular testing report Cincinnati Children's Guidelines
Weight Documentation Current weight for dosing Recent clinic notes or growth charts FDA Prescribing Information
Infusion Plan Safety monitoring protocol Detailed infusion procedures Elaprase Dosing Guidelines

Required Diagnostic Documentation

Essential Test Results

Enzymatic Testing:

  • I2S enzyme activity assay from blood, serum, or dried blood spot
  • Results showing severely reduced or absent enzyme activity
  • Urine GAG testing (elevated dermatan sulfate and heparan sulfate)

Genetic Confirmation:

  • IDS gene sequencing report identifying pathogenic variant
  • Molecular testing from CLIA-certified laboratory
  • Family history documentation if available

Clinical Documentation:

  • Complete medical history with MPS II symptoms
  • Physical examination findings
  • Developmental assessments (if pediatric patient)
  • Pulmonary function tests and cardiac evaluations
Tip: Submit both enzymatic and genetic test reports together. Insurance often denies requests with only one type of confirmation.

Infusion Site and Monitoring Requirements

Safety Protocol Mandates

Blue Cross Blue Shield Virginia requires detailed infusion monitoring plans due to Elaprase's FDA boxed warning for anaphylaxis. Your plan must include:

Required Safety Measures:

  • Trained personnel present during all infusions
  • Immediate access to emergency resuscitation equipment
  • Patient observation during and up to 24 hours post-infusion
  • Written emergency response procedures

Infusion Settings:

  • Hospital outpatient infusion center (preferred)
  • Certified home infusion with qualified nursing
  • Specialty pharmacy infusion suite

Administration Protocol:

  • 3-hour infusion duration (may reduce to 1 hour if well-tolerated)
  • Start at 8 mL/hr, increase by 8 mL/hr every 15 minutes
  • Maximum rate: 100 mL/hr
  • Use 0.2 μm filter and low-protein-binding infusion set

FAQ

Q: How long does Blue Cross Blue Shield prior authorization take in Virginia? A: Standard PA decisions are made within 15 business days. Expedited reviews (for urgent medical needs) are completed within 72 hours.

Q: What if Elaprase is not on my plan's formulary? A: You can request a formulary exception by demonstrating medical necessity and lack of therapeutic alternatives. Since Elaprase is the only FDA-approved treatment for Hunter syndrome, this strengthens your case.

Q: Can I appeal if my child is denied coverage? A: Yes. The same appeals process applies to pediatric patients. Virginia offers special protections for children's healthcare needs.

Q: What happens if I miss the appeal deadline? A: Contact the Virginia Bureau of Insurance immediately. In some cases, exceptions may be granted for good cause, especially if you can demonstrate the delay wasn't your fault.

Q: Does step therapy apply if I've tried treatments in another state? A: Yes, previous treatment trials from other states count toward step therapy requirements. Ensure you have documentation of prior therapies and outcomes.

Q: How often do I need reauthorization? A: Typically annually, but may be more frequent if your clinical status changes or if you experience significant weight changes requiring dose adjustments.

From Our Advocates: We've seen families succeed by being proactive about documentation. One family we worked with (details anonymized) gathered all their genetic testing, enzyme assays, and clinical notes before even requesting prior authorization. When the initial request was denied for "insufficient documentation," they had everything ready for the appeal and got approval within two weeks. The key was having comprehensive records organized and ready to submit.
