Who Should Use This Checklist

This guide is designed for:

  • Parents and caregivers of high-risk infants and children needing RSV prevention
  • Healthcare providers submitting prior authorization requests to Blue Cross Blue Shield plans in California
  • Families facing denials who need to understand the appeal process

Expected outcome: With proper documentation meeting Blue Shield's clinical criteria, most eligible patients receive approval. If initially denied, California's robust appeal system provides strong consumer protections with high overturn rates.

Member & Plan Basics

Coverage Requirements

  • Active Blue Cross Blue Shield coverage in California (Blue Shield of California or Anthem Blue Cross)
  • Prior authorization mandatory - no exceptions for emergency administration
  • Deductible applies - Synagis is typically covered as a specialty medication after deductible is met
  • Plan type variations: HMO plans may require specialist referrals; PPO plans typically allow direct access to pediatric specialists
Note: Different rules apply for Federal Employee Program or Medi-Cal members - verify specific requirements through your plan's member portal.

Clinical Criteria Requirements

Indication and Label Status

Synagis is FDA-approved for prevention of serious RSV lower respiratory tract disease in specific high-risk pediatric populations:

Qualifying High-Risk Categories:

  • Premature infants born at <32 weeks gestation with continued oxygen requirements
  • Chronic lung disease of prematurity requiring medical support (corticosteroids, diuretics, supplemental oxygen)
  • Hemodynamically significant congenital heart disease requiring cardiac intervention
  • Immunocompromised patients under 24 months (solid organ transplant, HSCT, chemotherapy)
  • Down syndrome meeting other qualifying criteria
  • Post-surgical cardiac patients recovering from bypass or ECMO

Step Therapy Requirements

Critical requirement: Patient must not have received nirsevimab (Beyfortus) during the current RSV season. This represents Blue Shield's step therapy approach, with Beyfortus considered first-line for eligible infants.

Dosing and Duration

  • Standard dose: 15 mg/kg administered intramuscularly once monthly
  • Maximum: 5 doses per RSV season (November through March typically)
  • Extended dosing: Up to 6 doses may be approved for patients undergoing cardiac bypass or ECMO during RSV season

Coding and Billing Requirements

Primary Codes

  • HCPCS/CPT Code: 90378 (RSV monoclonal antibody, 50 mg each)
  • Administration: 96372 (therapeutic injection) if billing separately
  • NDC: 60574-4114-01 (50 mg/0.5 mL vial)

ICD-10 Diagnosis Codes

Common qualifying diagnoses:

  • P07.3: Preterm newborn, gestational age 28-36 weeks
  • P27.1: Bronchopulmonary dysplasia originating in perinatal period
  • Q20-Q28: Congenital malformations of circulatory system
  • D80-D89: Immunodeficiency disorders

Billing Units Calculation

  • 1 unit = 50 mg
  • Calculate total mg needed (patient weight × 15 mg/kg)
  • Divide by 50 mg and round up to next whole unit
  • Example: 6 kg child needs 90 mg = 2 units (100 mg total)

Documentation Packet

Provider Note Elements

Your clinical documentation must include:

  1. Patient demographics and insurance information
  2. Qualifying diagnosis with supporting evidence
  3. Gestational age (if applicable) and birth history
  4. Current clinical status and ongoing medical needs
  5. Previous RSV prophylaxis history (including nirsevimab)
  6. Weight-based dosing calculation
  7. Treatment plan through RSV season

Medical Necessity Letter Components

A comprehensive letter should address:

  • Medical problem: Specific high-risk condition placing patient at severe RSV risk
  • Clinical rationale: Why Synagis is medically necessary based on AAP guidelines
  • Prior treatments: Any previous RSV prophylaxis or hospitalizations
  • Contraindications: Why alternatives (like nirsevimab) are inappropriate
  • Expected outcomes: Prevention of RSV hospitalization and complications

Required Attachments

  • Recent clinic notes from pediatrician
  • Cardiology consultation (for cardiac patients)
  • Pulmonology records (for chronic lung disease)
  • Hospital discharge summaries (if applicable)
  • Growth charts and current vital signs
  • Laboratory results supporting diagnosis

Submission Process

Correct Forms and Portal Access

  • Primary method: Blue Shield Provider Connection portal (AuthAccel system)
  • Form verification: Always use current prior authorization forms - updated monthly
  • Portal access: Providers can track status and receive determinations online

Required Fields That Cause Rejections

Common submission errors to avoid:

  • Missing patient weight for dosing calculation
  • Incomplete diagnosis coding
  • Failure to document nirsevimab status
  • Missing specialist consultation notes
  • Incorrect NDC or billing codes
Tip: Double-check that all required fields are completed before submission. Incomplete forms cause automatic rejections and restart the review timeline.

Specialty Pharmacy Requirements

Blue Cross Blue Shield typically requires Synagis distribution through contracted specialty pharmacies.

Preferred Vendors

  • Verify current preferred pharmacy network through member portal
  • Some plans allow physician office administration with proper billing
  • Buy-and-bill may be permitted for established pediatric practices

Transfer and Shipment Process

  1. Prescription routing to designated specialty pharmacy
  2. Prior authorization must be approved before shipment
  3. Temperature-controlled delivery to clinic or patient home
  4. Administration scheduling coordinated with healthcare provider

After Submission: What to Expect

Timeline and Status Tracking

  • Standard review: 3-5 business days for routine requests
  • Expedited review: 24-72 hours for urgent clinical situations
  • Status updates: Available through provider portal
  • Written notification: Mailed to provider and patient

Documentation to Maintain

  • Confirmation numbers for all submissions
  • Review correspondence and determination letters
  • Appeal deadlines if denial occurs
  • Reauthorization dates for subsequent doses

Common Denial Reasons & Prevention

Denial Reason Prevention Strategy Documentation Needed
Outside high-risk criteria Provide specialist consultation Cardiology/pulmonology notes
Prior nirsevimab use Document contraindication Clinical rationale letter
Incomplete medical records Submit comprehensive packet All qualifying documentation
Dosing/weight discrepancies Verify calculations Current weight measurements
Missing step therapy Document failed alternatives Prior treatment history

Five Critical Pitfalls to Avoid

  1. Submitting without specialist consultation for cardiac/pulmonary patients
  2. Missing nirsevimab documentation - must address current season status
  3. Incomplete dosing justification - weight and calculation errors
  4. Generic clinical notes - need RSV-specific risk documentation
  5. Wrong submission pathway - using outdated forms or incorrect portal

Independent Medical Review (IMR)

  1. Eligibility: Must complete internal appeal first (unless urgent)

From our advocates: "We've seen families successfully overturn Synagis denials by providing comprehensive cardiology documentation showing hemodynamically significant heart disease. The key was demonstrating that the child met specific AAP criteria that the plan initially overlooked. California's IMR process gave them a fair review by cardiac specialists who understood the medical necessity."
