Who Should Use This Guide

This guide helps Michigan residents with Cigna coverage who need Rapivab (peramivir) for acute influenza treatment. You'll need this if:

  • Your doctor prescribed IV peramivir for influenza within 48 hours of symptom onset
  • You can't take or have failed oral antivirals like Tamiflu (oseltamivir)
  • You received a Cigna denial for peramivir coverage
  • You're a healthcare provider submitting prior authorization for patients

Expected outcome: Following this checklist significantly improves approval odds and reduces processing delays. If initially denied, the appeals process in Michigan has strong patient protections with binding external review.

Member & Plan Basics

Verify Your Coverage

  • Active Cigna membership in Michigan required
  • Check your member ID card for plan type (commercial, Medicare Advantage, Medicaid)
  • Confirm your plan includes prescription drug coverage
  • Note your deductible status—high-deductible plans may require meeting deductible first

Authorization Requirements

Cigna requires prior authorization for Rapivab across most plan types. The medication is typically:

  • Non-formulary or high-tier formulary placement
  • Subject to step therapy (must try preferred alternatives first)
  • Quantity limited to single-dose treatment courses
Tip: Call Cigna member services at the number on your card to confirm your specific plan's requirements before starting the PA process.

  • Documented allergy or intolerance to oral alternatives
  • Hospitalized patient requiring IV access

Dosing and Duration

  • Treatment course is single dose only

Coding Requirements

HCPCS Billing Code

  • "Hospitalized patient with IV access already established"

Treatment plan: "Single-dose IV peramivir 600 mg over 15-30 minutes per FDA labeling"

Supporting evidence: Reference CDC influenza antiviral guidelines and FDA approval for neuraminidase inhibitor class.

Specialty Pharmacy Coordination

Cigna's Preferred Vendors

Rapivab may be dispensed through:

  • Accredo Specialty Pharmacy (Express Scripts network)
  • Hospital/clinic pharmacy for immediate administration
  • Approved infusion centers

Coordination Steps

  1. Verify coverage before ordering from specialty pharmacy
  2. Coordinate delivery to infusion site or clinic
  3. Confirm administration timing within 48-hour window
  4. Document receipt and preparation for billing
Note: Since Rapivab requires IV administration by healthcare professionals, most patients receive treatment at clinics or hospitals rather than home infusion.

After Submission: What to Expect

Confirmation and Tracking

  • Record confirmation number from submission
  • Check status every 3-5 business days via provider portal
  • Document all communications with date, time, and representative name

Possible Outcomes

  • Approved: Coverage authorized for specified quantity/duration
  • Denied: Receive written denial with specific reasons
  • Pending: Additional information requested

If Additional Information Requested

Respond within 14 days to avoid automatic denial. Common requests:

  • More detailed clinical notes
  • Lab results confirming influenza
  • Documentation of failed prior therapies
  • Peer-to-peer review with medical director

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
Symptom onset >48 hours Provide timeline showing ≤48h Clinic notes with precise onset time
No trial of oral antivirals Document contraindications Allergy history, previous prescriptions
Not medically necessary Clinical justification letter Hospital admission, severity indicators
Missing flu diagnosis Submit lab confirmation Rapid flu test, clinical diagnosis
Quantity limits exceeded Confirm single-dose request Prescription for 600mg x1 dose only

Five Common Pitfalls to Avoid

  1. Late submission: Submit PA before 48-hour treatment window closes
  2. Incomplete step therapy: Document all preferred alternatives tried
  3. Missing clinical details: Include specific symptom onset date/time
  4. Wrong diagnosis code: Use most specific ICD-10 for flu type
  5. Inadequate justification: Explain why IV route is medically necessary

Appeals Process for Michigan Residents

Internal Appeals (Cigna)

  • Filing deadline: 180 days from denial notice
  • Standard appeal: 30-day decision timeline
  • Expedited appeal: 24-48 hours if health at risk

Expedited Appeals for Flu Treatment

For urgent influenza treatment needs:

  1. Request expedited internal appeal with physician letter
  2. Emphasize 48-hour treatment window in all communications
  3. File expedited external review if internal appeal denied
  4. Get physician attestation that delay would harm patient health
From our advocates: In our experience helping Michigan patients, Cigna influenza antiviral denials are often overturned on appeal when providers clearly document the medical necessity for IV treatment and the inability to use oral alternatives. The key is thorough documentation of why the patient specifically needs IV peramivir rather than oral options.

Q: What if Rapivab isn't on my Cigna formulary? A: You can request a formulary exception by demonstrating medical necessity and that preferred alternatives aren't suitable. Include clinical documentation supporting IV peramivir over oral options.

Q: Can I get expedited approval for influenza treatment? A: Yes, if your doctor certifies that delay would seriously jeopardize your health. The 48-hour treatment window for flu antivirals often qualifies for expedited review.

Q: Does step therapy apply if I tried oral antivirals outside Michigan? A: Yes, previous trials from any location count toward step therapy requirements. Provide prescription records and clinical notes documenting the trials and outcomes.

Q: What's the cost of Rapivab with Cigna coverage? A: Costs vary by plan. Cash prices typically range $900-$1,000 per dose. Check your specific copay/coinsurance amounts and whether you've met your deductible.
