Policy Overview: How Cigna Covers Sylvant

Cigna manages Sylvant (siltuximab) as a specialty medication requiring prior authorization across all plan types—HMO, PPO, and Medicare Advantage. The drug is typically processed through Express Scripts/Accredo Specialty Pharmacy, Cigna's preferred specialty pharmacy network.

Plan Coverage Variations:

  • Commercial plans: Subject to formulary tier placement and PA requirements
  • Medicare Advantage: May have additional quantity limits and step therapy protocols
  • Medicaid managed care: Follows state Medicaid guidelines with Cigna-specific PA forms
Note: Self-funded employer plans follow ERISA rules but often use similar PA criteria. Check your Summary Plan Description for specific coverage details.

Indication Requirements: What Counts as Medical Necessity

Cigna's medical necessity criteria for Sylvant align with FDA labeling and require strict documentation of the following:

FDA-Approved Indication

Sylvant is approved for treating HIV-negative and HHV-8-negative idiopathic multicentric Castleman disease (iMCD). Off-label use typically requires additional justification and may face higher denial rates.

Required Clinical Documentation

According to Cigna's prior authorization requirements:

  • HIV status: Documented negative HIV test results
  • HHV-8 status: Documented negative human herpes virus-8 test results
  • Disease confirmation: Multicentric vs. unicentric Castleman disease classification
  • Patient weight: Current weight in kilograms for dosing calculations
  • Chronic condition verification: Documentation of ongoing, long-term treatment need

Step Therapy & Exceptions

Based on available Cigna formulary documents, step therapy requirements for Sylvant are not explicitly documented in standard formulary materials. However, this doesn't guarantee step therapy won't apply to your specific plan.

Medical Exception Pathways

If step therapy is required, you can request exceptions for:

  • Contraindications to preferred alternatives
  • Previous treatment failures with required therapies
  • Documented intolerance to step therapy medications

Submit exception requests through the same PA portal with supporting clinical documentation.

Quantity and Frequency Limits

Standard Dosing Protocol

Sylvant is dosed at 11 mg/kg intravenously every 3 weeks until treatment failure. Cigna's quantity limits typically align with this FDA-approved dosing schedule.

Coverage Considerations

  • Weight-based calculations: Ensure accurate patient weight documentation
  • Infusion frequency: Every 3 weeks (may extend to every 6 weeks based on clinical response)
  • Duration limits: Most plans don't impose arbitrary duration caps for rare disease treatments, but periodic reviews are common
Tip: Include a treatment plan timeline in your PA submission showing expected duration and monitoring schedule.

Required Diagnostics and Documentation

Essential Laboratory Tests

Before each infusion during the first 12 months, then every 3 cycles thereafter:

  • Absolute neutrophil count: ≥1.0 × 10⁹/L
  • Platelet count: ≥75 × 10⁹/L initially, ≥50 × 10⁹/L for retreatment
  • Comprehensive metabolic panel
  • Liver function tests

Diagnostic Confirmation Requirements

  1. Lymph node biopsy: Excisional biopsy showing characteristic iMCD histopathology
  2. HIV testing: Documented negative results
  3. HHV-8 testing: Documented negative results
  4. Imaging studies: CT or PET scans showing multicentric lymphadenopathy ≥1 cm

Site of Care and Specialty Pharmacy Requirements

Administration Settings

Sylvant must be administered by qualified healthcare professionals under medical supervision in appropriate clinical settings:

  • Hospital outpatient infusion centers
  • Oncology clinics with infusion capabilities
  • Specialty infusion centers

Pharmacy Routing

  • Preferred: Accredo Specialty Pharmacy (Cigna's national specialty pharmacy)
  • Alternative: Other approved specialty pharmacies in Cigna's network
  • Buy-and-bill: Some practices may purchase and bill directly (requires specific authorization)

Contact Information

Timeline

  • Standard review: 30 days for decision
  • Expedited review: 72 hours for urgent cases
  • IRO decision: Binding on Cigna if coverage is approved
From our advocates: We've seen cases where initial Sylvant denials were overturned on external review when prescribers included comprehensive diagnostic documentation and cited the lack of alternative FDA-approved treatments for iMCD. The key was demonstrating that all diagnostic criteria were met and that the requested therapy aligned precisely with FDA labeling.

Denial Reason How to Overturn Required Documentation
Missing HIV/HHV-8 status Submit negative test results Laboratory reports with dates
Insufficient diagnostic proof Provide biopsy confirmation Pathology report showing iMCD features
