How to Use This Decision Tree

This guide helps patients and clinicians navigate Blue Cross Blue Shield's prior authorization process for Aldurazyme (laronidase) in Virginia. Work through each section based on your current situation—whether you're preparing an initial request, appealing a denial, or gathering documentation.

Important: Blue Cross Blue Shield operates 33 independent plans. In Virginia, Anthem Blue Cross Blue Shield holds the largest market share at approximately 43%. While core requirements are similar across Blue plans, specific forms and submission processes may vary by your exact plan.

Eligibility Triage: Do You Qualify?

Likely Eligible ✅

You probably qualify for coverage if you have:

  • Confirmed MPS I diagnosis through genetic testing (IDUA gene mutations) or enzyme assay showing α-L-iduronidase deficiency
  • Documented disease severity with baseline assessments of organ involvement
  • Age-appropriate indication (Aldurazyme is approved for all MPS I subtypes: Hurler, Hurler-Scheie, and Scheie)
  • Infusion center access with appropriate monitoring capabilities

Possibly Eligible ⚠️

You may need additional documentation if:

  • Diagnosis is based only on clinical symptoms without biochemical confirmation
  • Missing baseline pulmonary function tests, echocardiogram, or other severity markers
  • Previous enzyme replacement therapy was interrupted without clear restart rationale
  • Requesting dosing outside FDA-approved parameters

Not Yet ❌

Coverage is unlikely without:

  • Confirmed MPS I diagnosis (other mucopolysaccharidosis types require different treatments)
  • Documentation of medical necessity for enzyme replacement therapy
  • Appropriate specialist involvement (typically genetics, metabolic medicine, or pediatrics)

If "Likely Eligible": Document Checklist

Required Clinical Documentation

Diagnostic Confirmation:

  • Enzyme assay results showing α-L-iduronidase deficiency
  • Genetic testing confirming IDUA gene mutations
  • Elevated urinary glycosaminoglycans (GAGs) - specifically dermatan sulfate and heparan sulfate

Baseline Disease Assessment:

  • Pulmonary function tests
  • Echocardiogram and cardiac evaluation
  • Hepatosplenomegaly assessment (imaging if indicated)
  • Joint range of motion evaluation
  • Ophthalmologic examination
  • Audiologic evaluation

Treatment Plan:

  • Comprehensive infusion monitoring protocol
  • Pre-medication strategy (antihistamines/antipyretics)
  • Emergency management plan for infusion reactions
  • Long-term monitoring schedule

Submission Process

  1. Contact your BCBS plan to confirm current prior authorization requirements
  2. Submit through provider portal or fax completed forms with all supporting documentation
  3. Include prescription with specific dosing: 0.58 mg/kg weekly IV infusion
  4. Attach specialist letter detailing medical necessity and treatment goals

If "Possibly Eligible": Tests to Request

Missing Diagnostic Elements

If your diagnosis needs strengthening:

  • Enzyme assay: Request α-L-iduronidase activity measurement in blood or dried blood spot
  • Genetic testing: IDUA gene sequencing to identify specific mutations
  • Family studies: Testing of parents/siblings if indicated for genetic counseling

Baseline Assessments

Essential evaluations that insurers typically require:

  • Pulmonary function: Spirometry and sleep study if sleep apnea suspected
  • Cardiac assessment: Echocardiogram, EKG, and blood pressure monitoring
  • Skeletal evaluation: Joint mobility assessment and imaging if indicated
  • Neurologic screening: Developmental assessment and MRI if cognitive involvement

Timeline for Reapplication

  • Allow 2-4 weeks for genetic testing results
  • Schedule baseline assessments within 30 days of test completion
  • Resubmit PA request within 60 days of obtaining complete documentation

If "Not Yet": Preparing Exception Requests

Alternative Diagnoses

If you have a different mucopolysaccharidosis type:

  • MPS II (Hunter syndrome): Requires idursulfase (Elaprase)
  • MPS VI (Maroteaux-Lamy): Requires galsulfase (Naglazyme)
  • MPS IVA (Morquio A): Requires elosulfase alfa (Vimizim)

Building Your Exception Case

For off-label use or unusual circumstances:

  1. Literature review: Gather peer-reviewed studies supporting your specific indication
  2. Expert opinion: Obtain second opinion from MPS specialist
  3. Compassionate use: Consider manufacturer patient assistance programs
  4. Clinical trial options: Research ongoing studies through ClinicalTrials.gov

If Denied: Virginia Appeal Path

Level 1: Internal Appeal

Timeline: Submit within 180 days of denial notice Process: BCBS reviews denial with additional documentation Expected response: 30 days for standard review, 72 hours for expedited

Level 2: External Review

Virginia's external review process provides independent oversight through the State Corporation Commission Bureau of Insurance.

Eligibility: Must exhaust internal appeals (except for cancer treatment) Timeline: Submit Form 216-A within 120 days of final internal denial Decision timeframe: 45 days standard, 72 hours expedited Cost: Free to patients

Submission methods:

  • Fax: (804) 371-9915
  • Email: [email protected]
  • Mail: State Corporation Commission, Bureau of Insurance – External Review, P.O. Box 1157, Richmond, VA 23218

Expedited Appeals

For urgent medical situations, your physician can complete Form 216-C certifying that treatment delay would seriously jeopardize your health.

From our advocates: "We've seen the strongest approval success when families work closely with an MPS specialist who can provide comprehensive baseline assessments and detailed treatment rationales. The key is demonstrating both the confirmed diagnosis and the medical necessity for enzyme replacement therapy. While the process can feel overwhelming, Virginia's external review system provides an important safety net if initial requests are denied."

FAQ: Blue Cross Blue Shield Aldurazyme Coverage

Q: How long does BCBS prior authorization take in Virginia? A: Standard PA decisions typically take 14-30 days. Expedited requests (when medically urgent) should receive response within 72 hours.

Q: What if Aldurazyme isn't on my plan's formulary? A: You can request a formulary exception with documentation of medical necessity. The process is similar to standard PA but may require additional justification.

Q: Can I request expedited appeal if my child needs treatment urgently? A: Yes. Your physician must complete Form 216-C certifying that delay would jeopardize health. Virginia processes expedited external reviews within 72 hours.

Q: Does step therapy apply to Aldurazyme? A: Unlikely, since Aldurazyme is the only FDA-approved enzyme replacement for MPS I. However, plans may require documentation that hematopoietic stem cell transplant isn't appropriate.

Q: What's the success rate for Aldurazyme appeals in Virginia? A: Specific success rates aren't published, but appeals with complete diagnostic documentation and specialist support have higher approval rates.

Q: Are there financial assistance programs available? A: Yes. Sanofi's patient assistance program may help with copays and coverage gaps. Contact them directly for eligibility requirements.
