Blue Shield of California requires prior authorization for Rapivab (peramivir) with strict criteria: symptoms ≤48 hours, documented intolerance to oral antivirals (Tamiflu, Relenza, Xofluza), and positive flu test. Submit PA via fax with clinical documentation. If denied, file internal appeal within plan deadlines, then request California's Independent Medical Review (IMR) through DMHC. Success rates for specialty drug appeals can exceed 50% with proper documentation.

First step today: Contact your doctor to document why oral antivirals won't work and ensure symptom timeline is ≤48 hours.

Step-by-Step: Fastest Path to Approval

1. Confirm Timing (Patient + Doctor)

Document exact flu symptom onset date. Rapivab must be given within 48 hours for coverage approval. If you're past this window, focus on documenting severe symptoms or complications.

2. Gather Prior Treatment History (Patient)

List all previous antiviral medications tried, including:

  • Dates of use
  • Reasons for stopping (side effects, ineffectiveness)
  • Supporting documentation from pharmacy records

3. Schedule Urgent Provider Visit (Patient)

Call your doctor's office and explain you need urgent evaluation for IV flu treatment. Mention the 48-hour requirement for insurance coverage.

4. Clinical Documentation (Doctor)

Your provider must document:

  • Positive influenza test (rapid antigen or PCR)
  • Why oral antivirals are inappropriate
  • Symptom severity and timeline
  • Risk factors for complications

5. Submit Prior Authorization (Doctor's Office)

Fax completed PA request with supporting documentation. Blue Shield typically responds within 24-72 hours for urgent requests.

6. Administration Coordination (Patient + Doctor)

Once approved, coordinate with an infusion center, hospital, or clinic capable of IV administration within the approval timeframe.

7. Follow-Up Documentation (Patient)

Save all approval letters, EOBs, and treatment records for potential appeals or future treatments.

Contraindication Documentation

Clear evidence why oral options won't work:

  • Persistent vomiting preventing oral medication absorption
  • Swallowing difficulties or feeding tube complications
