Medical Necessity Documentation

Clinician Corner: Medical Necessity Letter Checklist

Your specialist's letter should include:

Patient Information

  • Confirmed diagnosis of idiopathic multicentric Castleman disease
  • HIV-negative and HHV-8-negative status with test dates
  • Previous treatments tried and outcomes
  • Current disease status and symptoms

Clinical Rationale

  • Why Sylvant is medically necessary for this patient
  • Expected benefits based on published evidence
  • Risks of delaying or withholding treatment
  • Lack of suitable alternatives

Supporting Evidence

  • FDA labeling for multicentric Castleman disease
  • Published clinical trials and case series
  • Consensus guidelines from hematology/oncology societies

Diagnostic Requirements

Pathology Confirmation

  • Excisional lymph node biopsy preferred
  • Characteristic histologic features of Castleman disease
  • HHV-8 LANA-1 immunohistochemistry (negative)
  • Rule out lymphoma and other mimickers

Laboratory Requirements

  • HIV testing (negative result required)
  • HHV-8 DNA PCR (negative or low level)
  • Baseline labs: CBC, CMP, inflammatory markers
  • Pre-infusion monitoring per protocol

Site of Care Requirements

Sylvant must be administered in settings with full resuscitation capability due to risk of severe infusion reactions.

Approved Settings

  • Hospital outpatient departments: Preferred for initial infusions
  • Qualified infusion centers: Must have emergency protocols
  • Home infusion: Generally not appropriate due to safety requirements

Safety Requirements

  • Resuscitation equipment and medications available
  • ACLS-trained staff present during infusion
  • Established protocols for managing severe reactions
  • Rapid access to emergency care if needed

Cigna may apply site-of-care steerage to prefer non-hospital settings when safe and available, but safety requirements typically favor institutional settings for Sylvant.

Cost and Financial Assistance

Manufacturer Support

Sylvant Support offers:

  • Insurance navigation assistance
  • Copay assistance for eligible commercial patients
  • Patient assistance programs for uninsured/underinsured
  • Coordination with specialty pharmacies like Accredo

Pennsylvania Resources

  • Pennsylvania Insurance Department: Consumer assistance for appeals
  • Pennsylvania Health Law Project: Free legal help for complex cases
  • Pennie marketplace: Assistance for exchange plan issues
From our advocates: We've seen patients reduce their Sylvant costs from thousands to under $100 per month by combining manufacturer copay assistance with successful prior authorization appeals. The key is starting the financial assistance application early in the PA process, not waiting for approval.
