Why Myths About Rare Disease Coverage Persist

When you're dealing with an ultra-rare condition like Mucopolysaccharidosis VII (MPS VII), misinformation spreads quickly through patient communities and even healthcare offices. Unlike common medications where coverage patterns are well-established, specialty enzyme replacement therapies like Mepsevii face unique approval challenges that generate confusion.

The complexity of Aetna's prior authorization process, combined with New Jersey's specific appeal regulations, creates a perfect storm for myths to take root. Well-meaning friends, online forums, and even some healthcare staff may share outdated or incorrect information about what it takes to get this $2,941-per-vial treatment approved.

Understanding the facts—backed by actual policy documents and state regulations—can save you months of delays and unnecessary stress. Let's separate myth from reality.

Common Myths vs. Facts

Myth 1: "If my doctor prescribes Mepsevii, Aetna has to cover it"

Fact: Prior authorization is required for all Mepsevii prescriptions through Aetna CVS Health, regardless of medical necessity. Your specialist must submit specific diagnostic documentation including enzyme assay results, genetic testing, and elevated urinary GAG levels before any coverage decision is made.

Myth 2: "I need to try other treatments first (step therapy)"

Fact: Mepsevii is the only FDA-approved enzyme replacement therapy for MPS VII. There are no alternative ERTs to "step through." However, Aetna still requires comprehensive documentation of your MPS VII diagnosis and clinical symptoms before approval.

Myth 3: "Appeals take over a year in New Jersey"

Fact: New Jersey's timeline is actually quite efficient. Internal appeals with Aetna take 30-45 days for standard requests (72 hours for expedited). External review through IHCAP takes 45 days maximum, with expedited reviews completed within 48 hours for urgent cases.

Myth 4: "Only pediatric patients get approved"

Fact: Mepsevii is FDA-approved for both pediatric and adult patients with MPS VII. Age is not a determining factor for coverage—meeting diagnostic criteria and demonstrating clinical need are what matter.

Myth 5: "If I'm denied once, I can't reapply"

Fact: You can file multiple prior authorization requests if your clinical status changes or if additional documentation becomes available. New Jersey law also protects continued coverage during appeals for drugs previously covered.

Myth 6: "Generic alternatives are just as effective"

Fact: There are no generic versions of Mepsevii. It's a recombinant human β-glucuronidase enzyme specifically manufactured by Ultragenyx for MPS VII treatment. No biosimilar alternatives exist.

Myth 7: "I have to pay for external appeals"

Fact: While New Jersey charges a $25 filing fee for IHCAP external reviews, this fee is refunded if you demonstrate financial hardship. The insurance company bears all other costs of the review process.

Myth 8: "CVS Specialty will automatically dispense once approved"

Fact: Accredo is the exclusive specialty pharmacy for Mepsevii dispensing and home infusion services, not CVS Specialty. Your prescription will be routed to Accredo regardless of your plan's typical specialty pharmacy.

What Actually Influences Approval

Based on Aetna CVS Health's actual policy requirements, approval hinges on four key factors:

1. Definitive MPS VII Diagnosis

  • Enzyme assay showing β-glucuronidase deficiency
  • Genetic testing confirming pathogenic GUSB gene mutations
  • Both tests are typically required, not either/or

2. Elevated Biomarkers

  • Urinary GAG excretion at minimum 2-fold above age-appropriate normal levels
  • Documentation must be from a certified laboratory
  • Baseline levels establish treatment monitoring benchmarks

3. Specialist Involvement

  • Prescription must come from or involve consultation with a metabolic disease specialist
  • Lysosomal storage disorder expertise is specifically valued
  • General pediatricians or internists may need specialist co-signature

4. Clinical Manifestations

  • Evidence of MPS VII symptoms: skeletal deformities, hepatosplenomegaly, joint limitations
  • Functional assessments (6-minute walk test, pulmonary function)
  • Documentation of disease progression or current impairment

Counterforce Health specializes in turning these complex requirements into targeted, evidence-backed appeals that align with each payer's specific criteria. Their platform analyzes denial letters against plan policies to identify exactly which documentation gaps need addressing.

Avoid These Preventable Mistakes

1. Submitting Incomplete Diagnostic Documentation Don't assume your specialist's office has submitted everything. Request copies of your enzyme assay results, genetic testing reports, and urinary GAG levels. Aetna's reviewers need to see specific numerical values, not just "abnormal" notations.

2. Missing the Specialist Requirement If your current prescriber isn't recognized as a metabolic specialist, get a consultation note or co-signature from someone who is. This single oversight causes many preventable denials.

3. Ignoring Dosing Limits Aetna's policy caps Mepsevii at 4 mg/kg every two weeks. Requests exceeding this limit face automatic denial unless exceptional circumstances are documented with literature support.

4. Failing to Document Clinical Need "Patient has MPS VII" isn't enough. Include functional assessments, organ measurements, and specific symptoms that demonstrate why enzyme replacement therapy is medically necessary now.

5. Missing Appeal Deadlines You have 180 days from Aetna's denial to file an internal appeal, and 4 months from the final internal denial to request external review through IHCAP. Mark these dates immediately when you receive denial notices.

New Jersey Protections

From Our Advocates: We've seen cases where families assumed they had to stop Mepsevii during the appeal process, not realizing New Jersey law protects continued coverage for rare disease treatments. One family we worked with maintained their child's therapy throughout a 3-month appeal that ultimately succeeded, avoiding potentially irreversible disease progression.

Coverage Documentation

Frequently Asked Questions

How long does Aetna prior authorization take for Mepsevii in New Jersey? Standard prior authorization decisions typically take 30-45 days. Expedited requests for urgent medical situations are processed within 72 hours.

What if Mepsevii isn't on Aetna's formulary? You can request a formulary exception by demonstrating medical necessity and lack of suitable alternatives. Since Mepsevii is the only ERT for MPS VII, exception requests often succeed with proper documentation.

Can I request an expedited appeal if my condition is worsening? Yes. If waiting for a standard appeal decision would jeopardize your health, both Aetna's internal process and New Jersey's IHCAP offer expedited reviews with much shorter timelines.

Does step therapy apply if I've tried treatments outside New Jersey? Treatment history from other states is considered in coverage decisions. Document all prior therapies, their outcomes, and reasons for discontinuation to support your Mepsevii request.

What counts as medical necessity for Mepsevii? Medical necessity requires confirmed MPS VII diagnosis, elevated urinary GAGs, clinical symptoms of the disease, and specialist recommendation. Progressive functional decline or organ involvement strengthens the case.
