When to Start Your Synagis Renewal

Aetna CVS Health requires fresh prior authorization for each RSV season - approvals do not automatically carry over year to year. Illinois follows typical RSV season timing from November through March, though exact dates may vary based on local surveillance data.

Renewal Triggers

Start your renewal process when:

  • 2-4 weeks before RSV season begins (typically late October for November start)
  • Your child remains in a qualifying high-risk category
  • Clinical status documentation is within 6 months
  • Previous season's authorization is expiring
Tip: Set a calendar reminder for September 15th each year to begin gathering renewal documentation, even though submission won't occur until October.

2025 Season Changes & Discontinuation

Critical Update: Multiple sources confirm that palivizumab will be discontinued December 31, 2025. This makes the 2024-2025 RSV season potentially the final opportunity for Synagis coverage.

What This Means for Renewal

  • This may be your last renewal - plan accordingly with your care team
  • Increased step therapy requirements - Aetna now requires trying Beyfortus (nirsevimab) first unless contraindicated
  • Transition planning needed for future RSV seasons using alternative prophylaxis

Illinois Department of Healthcare and Family Services has already announced that "palivizumab is no longer routinely recommended for use and will be discontinued as of December 31, 2025."

Updated Evidence Requirements

For seasonal renewal, you'll need to demonstrate continued medical necessity with current clinical documentation.

Clinical Documentation Checklist

For Chronic Lung Disease of Prematurity:

  • Proof of ongoing oxygen, diuretics, or steroids within past 6 months
  • Current pulmonology notes documenting continued risk
  • Growth and development assessment

For Congenital Heart Disease:

  • Cardiology evaluation within 6 months
  • Current medications for heart failure or pulmonary hypertension
  • Surgical history and planned interventions

For All High-Risk Categories:

  • Updated weight for dosing calculations (15 mg/kg monthly)
  • Confirmation of age eligibility at season start
  • Documentation that Beyfortus was not given this season
Clinician Corner: Medical necessity letters should explicitly state: (1) specific high-risk diagnosis with ICD-10 code, (2) why the child remains at substantially increased risk for severe RSV, (3) current therapies demonstrating ongoing medical complexity, and (4) that nirsevimab is contraindicated or unavailable if requesting step therapy exception.

Renewal Documentation Checklist

Required Documents

  • Aetna prior authorization form (obtain from provider portal)
  • Updated specialist notes (cardiology/pulmonology within 6 months)
  • Current medication list showing ongoing treatments
  • Growth chart with current weight for dosing
  • Previous season summary (doses received, dates, any adverse events)
  • Insurance verification confirming active Aetna coverage

Supporting Evidence

  • Birth history (gestational age, NICU course if applicable)
  • Recent hospitalizations or emergency visits
  • Laboratory results if relevant to underlying condition
  • Step therapy exception request if Beyfortus contraindicated

From our advocates: One Illinois family successfully overturned an Aetna Synagis denial by providing detailed cardiology notes showing worsening pulmonary hypertension between seasons. The external review physician agreed that continued prophylaxis was medically necessary despite the child aging out of typical criteria. While outcomes vary, thorough documentation of evolving clinical status significantly improves appeal success rates.
