What Affects Sylvant Approval Timing

Several factors influence how quickly UnitedHealthcare approves Sylvant (siltuximab) in North Carolina:

Documentation completeness is the biggest factor. Complete submissions with all required lab results, pathology reports, and clinical notes process within 1-5 business days. Missing documentation can extend approval by 5-10 additional days for information requests.

Step therapy requirements may apply to your UnitedHealthcare plan. If step therapy is required, you'll need documented failure or contraindications to tocilizumab or rituximab-based regimens before Sylvant approval.

Plan type affects processing. Medicare Advantage plans follow Medicare Part B step therapy programs (effective January 2025), while commercial plans use OptumRx's clinical review system.

Medical urgency can accelerate review. If your oncologist documents worsening symptoms or disease progression, expedited review provides decisions within 72 hours.
