Set Your Goal: What Approval Requires

Your partnership with your doctor is crucial for getting Rapivab (peramivir) covered by Aetna CVS Health. This IV antiviral requires prior authorization because it's typically reserved for specific situations where oral or inhaled alternatives aren't suitable.

Coverage Requirements at a Glance

Requirement What It Means Documentation Needed
Prior Authorization Must be approved before dispensing Aetna PA form
Symptom Timeline ≤48 hours from flu onset Medical record with symptom start date
Alternative Failure Cannot use oral/inhaled antivirals Clinical notes explaining contraindications
FDA Indication Acute uncomplicated influenza, age ≥6 months Diagnosis with ICD-10 code
Single Dose 600mg IV for adults (weight-based for pediatrics) Dosing rationale in prescription

Your role: Come prepared with detailed symptom history and be ready to explain why you can't take Tamiflu (oseltamivir) or other alternatives. Your doctor's role is to document medical necessity and submit the prior authorization request.

Tip: Aetna processes most prior authorizations within 24 hours when complete documentation is provided. Missing information causes delays.

Visit Preparation: Document Your Case

Before your appointment, gather this information to help your doctor build the strongest possible case:

Symptom Timeline Documentation

  • Exact date and time symptoms began
  • Specific symptoms: fever, body aches, cough, fatigue
  • Severity: How symptoms impact daily activities
  • Temperature readings if available

Previous Treatment History

  • Other antivirals tried and outcomes (if any prior flu episodes)
  • Current medications that might interact with oral antivirals
  • Allergies or intolerances to oseltamivir, zanamivir, or baloxavir
  • Gastrointestinal issues preventing oral medication absorption

Medical Conditions

  • Chronic conditions that complicate oral antiviral use
  • Recent procedures affecting medication absorption
  • Swallowing difficulties or feeding tube dependence
  • Respiratory conditions preventing inhaled medication use

Building Your Evidence Kit

Work with your healthcare team to compile supporting documentation:

Laboratory Evidence

  • Positive influenza test (rapid antigen or PCR)
  • Recent lab work showing overall health status
  • Kidney function tests if relevant for dosing

Clinical Guidelines Support

Your doctor should reference these in the medical necessity letter:

Medication History Summary

  • Complete list of current prescriptions
  • Documentation of failed oral antivirals from previous flu episodes (if applicable)
  • Contraindications to standard flu treatments

Medical Necessity Letter Structure

Your doctor will need to write a comprehensive letter of medical necessity. Here's what should be included:

Essential Components

Patient Information:

  • Full name, date of birth, insurance ID
  • Contact information and prescriber details

Clinical Justification:

  • Diagnosis: Acute uncomplicated influenza with ICD-10 code
  • Symptom onset: Exact date/time (must be ≤48 hours)
  • Why alternatives aren't suitable: Specific medical reasons
  • Treatment urgency: Risks of delayed antiviral therapy

FDA Indication Statement: "Rapivab (peramivir) is FDA-approved for treatment of acute uncomplicated influenza in patients 6 months and older who have been symptomatic for no more than 2 days."

Dosing and Administration:

  • Adult dose: 600mg IV single infusion over 15-30 minutes
  • Pediatric dose: 12mg/kg (maximum 600mg) for ages 6-12 years
  • Renal adjustments if applicable

Sample Language for Common Scenarios

For severe nausea/vomiting: "Patient presents with severe nausea and vomiting preventing oral medication retention. Oral oseltamivir is not appropriate due to inability to maintain oral intake."

For respiratory compromise: "Patient's respiratory status precludes use of inhaled zanamivir. IV peramivir is medically necessary for effective antiviral therapy."

Supporting Peer-to-Peer Reviews

If the initial prior authorization is denied, your doctor can request a peer-to-peer review with an Aetna medical reviewer.

How to Help Your Provider

  • Offer flexible availability for the peer-to-peer call timing
  • Provide a concise case summary highlighting key points:
    • Exact symptom timeline
    • Specific contraindications to alternatives
    • Clinical urgency factors

Peer-to-Peer Process

  1. Provider contacts Aetna customer service to request peer-to-peer review
  2. Medical reviewer (physician) discusses case with your doctor
  3. Clinical justification presented in real-time
  4. Decision typically made during or immediately after the call
Note: Peer-to-peer reviews are separate from formal appeals and can often resolve denials more quickly.

After-Visit Documentation

Keep organized records of all communications and submissions:

What to Save

  • Copy of prior authorization request and all attachments
  • Confirmation numbers from online submissions
  • Fax confirmation sheets if submitted by fax
  • Provider portal screenshots showing submission status

Follow-Up Communication

  • Message your provider through the patient portal if you have additional information
  • Update symptom progression if condition changes while waiting for approval
  • Report any urgent developments that might warrant expedited review

Respectful Persistence and Follow-Up

Appropriate Follow-Up Cadence

  • 24-48 hours: Check submission status via provider portal
  • 72 hours: Contact provider's office if no response from Aetna
  • 5-7 days: Follow up on any additional documentation requests
  • 10 days: Escalate to formal appeal if still denied

How to Escalate Politely

To your provider's office: "I wanted to follow up on the Rapivab prior authorization submitted on [date]. My symptoms began on [date], so we're approaching the 48-hour window for optimal effectiveness. Could you please check the status or initiate a peer-to-peer review?"

To Aetna customer service: "I'm calling about prior authorization request #[number] for Rapivab. This is time-sensitive flu treatment, and I'd like to understand the review timeline."
