How to Get Mepsevii (vestronidase alfa-vjbk) Covered by Cigna in Washington: PA Forms, Appeals, and State Protections

Answer Box: Your Path to Mepsevii Coverage in Washington

Cigna covers Mepsevii (vestronidase alfa-vjbk) for confirmed MPS VII but requires prior authorization. For Washington residents, strong state appeal protections make denials often overturnable. First step today: Have your metabolic specialist submit Cigna's Mepsevii CCRD PA form via CoverMyMeds with genetic/enzyme test results. If denied, Washington's binding external review by an Independent Review Organization (IRO) gives you a second chance with medical experts—and many rare disease denials get overturned when properly documented.

Plan Types & Network Implications

Commercial vs. Self-Funded Plans Your Cigna plan type determines which Washington protections apply. Fully insured commercial plans follow Washington state law, giving you access to the state's powerful external review process. Self-funded/ERISA employer plans use federal external review through MAXIMUS instead.

Tip: Call Cigna at the number on your ID card and ask: "Is my plan fully insured in Washington or self-funded/ERISA?" This determines your appeal rights.

HMO vs. PPO Considerations

  • Cigna HMO: May require referrals to metabolic specialists
  • Cigna PPO/EPO: Direct access to specialists, but verify the metabolic geneticist is in-network

For MPS VII, you'll need ongoing care from a metabolic specialist familiar with lysosomal storage disorders—typically at a major medical center like Seattle Children's or University of Washington.

Formulary Status & Tier Placement

Mepsevii appears on Tier 4 (specialty tier) with prior authorization across most Cigna formularies. This means:

  • Higher cost-sharing than standard medications
  • Mandatory prior authorization before any coverage
  • Specialty pharmacy requirement (typically Accredo)
Plan Type Tier PA Required Step Therapy
Cigna Commercial Tier 4 Yes No
Cigna Medicare Specialty Tier Yes No
Cigna Oscar Tier 4 Yes No

No Step Therapy Required Unlike many specialty drugs, Mepsevii doesn't require trying other medications first because it's the only FDA-approved enzyme replacement therapy specifically for MPS VII.

Prior Authorization Requirements

Cigna's policy IP0449 outlines specific medical necessity criteria for Mepsevii:

Required Documentation:

  • Confirmed MPS VII diagnosis via enzyme assay showing deficient β-glucuronidase activity OR molecular genetic testing showing biallelic pathogenic GUSB gene variants
  • Specialist involvement: Prescribed by or in consultation with a geneticist, endocrinologist, or metabolic disorder subspecialist
  • Appropriate dosing: Maximum 4 mg/kg IV every 2 weeks (per FDA labeling)

Approval Duration: 1 year when criteria are met

Specialty Pharmacy Setup

Accredo is Cigna's Preferred Partner Most Cigna plans require Mepsevii to be dispensed through Accredo Specialty Pharmacy. The process involves:

  1. Provider submits prescription and clinical documentation to Accredo
  2. Benefits verification confirms coverage and patient cost-share
  3. Patient enrollment includes financial assistance screening
  4. Shipment coordination to home, clinic, or infusion center
Note: Accredo often helps enroll eligible patients in manufacturer copay assistance programs to reduce out-of-pocket costs.

Patient Enrollment Steps:

  • Accredo contacts you within 1-2 business days of prescription receipt
  • Complete patient profile and shipping preferences
  • Discuss injection training or infusion coordination if needed
  • Review financial assistance options

Cost-Share Basics

Typical Tier 4 Specialty Costs:

  • Deductible: Often applies before coverage begins
  • Coinsurance: Usually 25-40% after deductible
  • Out-of-pocket maximum: Varies by plan, typically $3,000-$8,000 annually

Financial Assistance Options:

  • Manufacturer copay cards (commercial insurance only)
  • Patient assistance programs for qualifying income levels
  • Foundation grants for rare disease medications
  • State programs may be available for certain situations
Important: Medicare and Medicaid patients cannot use manufacturer copay cards but may qualify for other assistance programs.

Common Denial Reasons & Solutions

Denial Reason Solution Required Documentation
Unconfirmed MPS VII diagnosis Submit enzyme assay and genetic testing Lab reports showing <10% normal β-glucuronidase activity
Lack of specialist involvement Provide specialist credentials and consultation notes CV or board certification of metabolic specialist
Dosing concerns Verify weight-based calculation Current weight and dose justification
Missing clinical rationale Submit detailed treatment plan Specialist note explaining expected benefits

Strengthening Your Case:

  • Include baseline functional assessments (6-minute walk test, pulmonary function)
  • Document multi-organ involvement typical of MPS VII
  • Provide evidence of disease progression without treatment
  • Reference FDA approval and lack of alternative therapies

Washington Appeals Process

Washington residents have particularly strong protections when Cigna denies rare disease medications.

Internal Appeals (Required First Step)

  • Deadline: 180 days from denial
  • Process: Call Cigna member services to initiate
  • Timeline: 30 days for standard review, 72 hours for urgent
  • Review: Different physician than original reviewer

External Review by IRO (Washington's Secret Weapon) For fully insured Cigna plans, Washington's Independent Review Organization process often succeeds where internal appeals fail.

  • Deadline: 120 days from final internal denial
  • Process: Contact Washington Office of Insurance Commissioner at 1-800-562-6900
  • Timeline: 20 days for standard review, 72 hours for expedited
  • Binding: IRO decision is legally binding on Cigna
From our advocates: We've seen several rare disease denials overturned at the Washington IRO level when families submitted comprehensive genetic testing, specialist letters detailing disease progression, and evidence that the medication is standard of care with no alternatives. The key is thorough documentation that addresses medical necessity head-on.

Self-Funded Plans (Federal External Review) If your Cigna plan is self-funded/ERISA:

  • External review through MAXIMUS (1-888-866-6205)
  • 4-month deadline from final internal denial
  • 45 days for standard review

Sources: Washington appeal regulations and Federal external review

When to Escalate

Contact Washington Office of Insurance Commissioner if:

  • Cigna fails to respond within required timeframes
  • You need help determining if your plan is state-regulated
  • You want assistance preparing an external review request
  • You suspect improper denial practices

Washington OIC Consumer Line: 1-800-562-6900

The OIC provides template appeal letters and can walk you through the external review process step-by-step.

Legal Considerations: For complex cases involving significant financial hardship or treatment delays, consider consulting with an attorney experienced in ERISA or Washington insurance law.

FAQ

What if Mepsevii isn't on my Cigna formulary? You can request a formulary exception through Cigna's appeals process. Washington residents have strong external review rights if the exception is denied. Include specialist documentation of medical necessity and lack of covered alternatives.

Can I get expedited review for Mepsevii appeals? Yes, if your metabolic specialist documents that treatment delay would "seriously jeopardize" your health or ability to regain function. Both Cigna internal appeals and Washington IRO reviews offer expedited timelines.

Does Washington's external review apply to all Cigna plans? Only for fully insured plans regulated by Washington state. Self-funded employer plans use federal external review through MAXIMUS. Call Cigna to confirm your plan type.

What counts as medical necessity for Mepsevii? Cigna requires confirmed MPS VII diagnosis via enzyme testing or genetic analysis, plus specialist involvement. Document baseline functional status and expected treatment benefits.

How much does Mepsevii cost with Cigna coverage? As a Tier 4 specialty drug, expect 25-40% coinsurance after deductible. Manufacturer copay assistance may significantly reduce costs for eligible commercial plan members.
