What Affects Approval Timing

Several factors influence how quickly Aetna (CVS Health) approves Sylvant (siltuximab) for multicentric Castleman disease:

Benefit Structure: Sylvant is typically covered under your medical benefit as a physician-administered infusion, not your pharmacy benefit. This means it goes through medical prior authorization rather than pharmacy PA, which can affect processing times.

Clinical Complexity: Since multicentric Castleman disease is rare, reviewers need clear documentation proving:

  • HIV-negative and HHV-8-negative status
  • Confirmed iMCD diagnosis with supporting pathology
  • Evidence that other treatments aren't appropriate

Documentation Completeness: The most common cause of delays is incomplete submissions. Missing lab results, unclear diagnosis codes, or insufficient prior therapy documentation can add 7-14 days to your timeline.

Note: Aetna reports that more than 95% of eligible prior authorizations are approved within 24 hours when all required documents are submitted correctly.

Pre-Submission Preparation (0-2 Days)
