Who Should Use This Guide

This guide is designed for patients with Humana coverage in Pennsylvania who need Rapivab (peramivir) for acute influenza treatment, as well as their healthcare providers. You'll find this most helpful if:

  • Your doctor has prescribed Rapivab but Humana requires prior authorization
  • You've received a denial for Rapivab coverage and need to appeal
  • You can't tolerate oral antivirals like oseltamivir (Tamiflu) or zanamivir (Relenza)
  • You need IV antiviral therapy due to severe symptoms or inability to keep oral medications down

Expected outcome: With proper documentation showing symptom onset within 48 hours and medical justification for IV therapy over oral alternatives, approval rates are generally favorable when clinical criteria are met.

Member & Plan Basics

Coverage Requirements

Requirement Details Source
Prior Authorization Required for all Humana plans Humana PA Lists
Benefit Channel Medical benefit (Part B), not pharmacy Humana Provider Resources
HCPCS Code J2547 (per 1 mg) Medicare billing requirements
Step Therapy Must try/fail oral antivirals first Humana formulary policies

Plan Type Considerations

Medicare Advantage members: Your appeals follow federal Medicare timelines, not Pennsylvania state processes. You have 60 days to file internal appeals and can request expedited review for urgent cases.

Commercial plan members: Follow Humana's internal appeal process first, then Pennsylvania's external review program if needed.

Clinical Criteria for Rapivab Coverage

FDA-Approved Indications

Rapivab is approved for acute, uncomplicated influenza in patients 6 months and older when:

  • Symptom onset is within 48 hours
  • Patient has been symptomatic for no more than 2 days

Humana's Medical Necessity Requirements

Based on Humana's prior authorization criteria, coverage typically requires:

  1. Documented influenza diagnosis with appropriate ICD-10 coding (J09-J11)
  2. Symptom onset within 48 hours with specific timeline documentation
  3. Medical contraindication to oral antivirals, such as:
    • Severe nausea/vomiting preventing oral intake
    • Gastrointestinal malabsorption disorders
    • Documented allergy or intolerance to oseltamivir or zanamivir
    • NPO (nothing by mouth) status
Clinician Corner: Document the specific medical reason why oral antivirals aren't appropriate. Generic statements like "patient prefers IV" won't meet medical necessity criteria.

Step Therapy Requirements

Humana requires documentation that oral alternatives have been:

  • Tried and failed due to side effects or lack of efficacy
  • Medically contraindicated due to patient-specific factors
  • Clinically inappropriate based on severity or absorption issues

Coding and Billing Requirements

ICD-10 Diagnosis Codes

Code Description When to Use
J09 Influenza due to identified novel virus Lab-confirmed novel strain (H5N1, etc.)
J10 Influenza due to other identified virus Lab-confirmed seasonal flu
J11 Influenza, virus not identified Clinical diagnosis without lab confirmation

HCPCS and Billing

  • Primary code: J2547 (peramivir, per 1 mg)
  • Standard adult dose: 600 mg (bill as 600 units)
  • Pediatric dosing: 12 mg/kg, maximum 600 mg
Note: Always use the most specific ICD-10 code available. If you have lab confirmation, never use J11.

Documentation Packet Essentials

Medical Necessity Letter Components

Your provider's letter should include:

  1. Patient demographics and insurance information
  2. Clear diagnosis with onset timeline
  3. Symptom documentation showing severity
  4. Prior treatment history including oral antiviral trials/contraindications
  5. Clinical rationale for IV therapy
  6. Dosing plan per FDA labeling

Required Attachments

  • Clinical notes documenting symptom onset
  • Laboratory results (if available)
  • Documentation of oral antiviral contraindications
  • Previous treatment records
  • Rapivab prescribing information
From Our Advocates: We've seen the strongest approvals when providers include specific dates and times for symptom onset, along with detailed documentation of why the patient can't keep oral medications down due to severe nausea or vomiting. Generic statements about "patient preference" typically result in denials.

Submission Process

Step-by-Step Submission

  1. Provider completes the Humana Medicare Prescription Drug Coverage Determination form
  2. Gather documentation including medical necessity letter and clinical notes
  3. Submit via fax to 877-486-2621 or through Humana's provider portal
  4. Confirm receipt and obtain confirmation number
  5. Track status through provider portal or by calling Humana
  6. Receive determination within 72 hours (24 hours for expedited)
  7. Proceed with treatment if approved, or initiate appeals process if denied

Emergency Situations

For urgent cases where delay would jeopardize patient health:

  • Prior authorization is not required for true emergencies
  • Document the emergency nature clearly
  • Submit PA retrospectively with emergency justification

Appeals Process in Pennsylvania

Internal Appeals (Required First Step)

Medicare Advantage members:

  • File within 60 days of denial
  • Standard review: 30 days
  • Expedited review: 72 hours for urgent cases
  • Submit through Humana member portal or by mail

Commercial members:

  • Follow Humana's internal process first
  • Timeline varies by plan type

Pennsylvania External Review

After exhausting internal appeals, Pennsylvania residents can access the state's Independent External Review Program:

Key benefits of Pennsylvania's program:

  • 50% success rate in 2024 - about half of appealed denials were overturned
  • 45-day timeline for standard reviews
  • 72-hour timeline for expedited reviews
  • 4-month window to file after final internal denial

How to file:

  1. Obtain Final Adverse Benefit Determination letter from Humana
  2. Submit external review request via Pennsylvania Insurance Department website
  3. Include all supporting documentation
  4. Independent Review Organization (IRO) reviews case
  5. Decision is binding on Humana
Tip: Pennsylvania's external review program has shown strong results for specialty medications when proper clinical documentation is provided.

Common Denial Reasons & Solutions

Denial Reason Solution Documentation Needed
Symptom onset >48 hours Provide precise timeline documentation Clinical notes with exact symptom start time
No contraindication to oral antivirals Document specific medical reasons Allergy history, GI issues, inability to swallow
Step therapy not met Show oral antiviral trials/failures Previous prescription records, side effect documentation
Not medically necessary Strengthen clinical justification Detailed provider letter with guideline references
Missing lab confirmation Provide diagnostic results when available Flu test results, viral cultures

Peer-to-Peer Review Strategy

If initially denied, request a peer-to-peer review where your provider can discuss the case directly with Humana's medical director. This often resolves coverage issues when clinical complexity isn't clear from documentation alone.
