Plan Types & Coverage Differences

Aetna CVS Health covers Synagis across HMO, PPO, and EPO plans, but the referral requirements and cost-sharing vary significantly.

Plan Type Referral for Specialist? Prior Authorization Network Restrictions
HMO Yes - PCP referral required Required for all plans In-network only
PPO No referral needed Required for all plans In/out-of-network (higher cost out-of-network)
EPO No referral needed Required for all plans In-network only
Note: Even with PPO or EPO plans where no referral is needed to see a pediatric pulmonologist or cardiologist, Aetna still requires prior authorization for Synagis regardless of your plan type.

For HMO members, coordinate with your primary care provider first to ensure proper referrals are in place before requesting Synagis from a specialist.

Formulary Status & Tier Placement

Synagis appears on Aetna's specialty drug formulary but with significant restrictions. As of 2024, Aetna considers Synagis medically necessary only when Beyfortus (nirsevimab) is not appropriate due to contraindication, intolerance, or ineffective response.

Key formulary details:

  • Tier placement: Specialty tier (typically tier 4 or 5)
  • Preferred alternative: Beyfortus is Aetna's preferred RSV prophylaxis agent
  • Seasonal restrictions: Maximum 5 doses per RSV season (November-March)
  • Duplicate therapy: Cannot receive both Synagis and Beyfortus in the same season

The shift toward Beyfortus reflects cost considerations—Synagis costs approximately $1,820 per 50mg vial compared to Beyfortus's lower acquisition cost.

Prior Authorization Requirements

All Aetna plans mandate precertification for Synagis through their Statement of Medical Necessity process.

Medical Necessity Criteria

Prematurity:

  • Gestational age <29 weeks, 0 days AND
  • Chronological age <12 months at start of RSV season

Chronic Lung Disease of Prematurity:

  • Gestational age <32 weeks, 0 days AND
  • Required >21% oxygen for first 28 days after birth AND
  • Either chronological age <12 months at first RSV season OR <24 months at subsequent season with ongoing medical support (chronic steroids, diuretics, supplemental oxygen) in prior 6 months

Required Documentation

Your pediatrician must provide:

  • Birth records showing gestational age
  • NICU discharge summary with oxygen therapy details
  • Current medical status and ongoing interventions
  • Clear justification why Beyfortus is not appropriate
  • ICD-10 diagnosis codes
Tip: Gather all birth and NICU records before starting the authorization process. Missing documentation is the most common cause of delays.

Specialty Pharmacy Routing

Aetna typically routes Synagis through CVS Specialty Pharmacy, though you may have options depending on your specific plan.

  1. Pediatrician completes prior authorization
  2. Upon approval, prescription can be sent to:
    • CVS Specialty Pharmacy (most common)
    • Physician's office for in-office administration
    • Approved retail pharmacy (limited)

CVS Specialty provides patient enrollment forms and coordinates delivery timing with your child's monthly dosing schedule.

Administration logistics:

  • Monthly intramuscular injections during RSV season
  • Dose calculation: 15mg/kg body weight
  • Must be administered by healthcare provider

Cost-Share Dynamics

Synagis falls under specialty drug cost-sharing, which varies significantly by plan design.

Typical cost-sharing patterns:

  • Specialty copay: $50-$150 per month
  • Specialty coinsurance: 20-40% after deductible
  • Annual out-of-pocket maximum: Applies to limit total yearly costs
Important: These are educational examples only. Check your specific plan's Summary of Benefits and Coverage for exact cost-sharing amounts.

Appeals Process in New York

From our advocates: We've seen families successfully overturn Synagis denials by providing detailed birth records and clear documentation of why Beyfortus wasn't suitable.

FAQ

How long does Aetna prior authorization take for Synagis in New York? Standard review takes 30-45 days, but expedited review is available within 72 hours for urgent cases where delay would jeopardize your child's health.

What if Synagis is denied as "not medically necessary"? File an internal appeal with additional clinical documentation. If upheld, request external review through NY Department of Financial Services, which has a 45-50% success rate for medication appeals.

Can I get Synagis if my child already received Beyfortus this season? Generally no. Aetna policy prohibits duplicate RSV prophylaxis in the same season unless there's documented treatment failure or contraindication.

Does step therapy apply to Synagis? Yes, Beyfortus is considered first-line therapy. You must demonstrate contraindication, intolerance, or ineffectiveness of Beyfortus to qualify for Synagis coverage.

What's the difference between HMO and PPO coverage for Synagis? Both require prior authorization, but HMO members need PCP referrals to see specialists who can prescribe Synagis. PPO members can go directly to pediatric subspecialists.

How much will Synagis cost with Aetna coverage? Cost-sharing varies by plan but typically involves specialty drug copays ($50-150) or coinsurance (20-40% after deductible). Check your specific plan's formulary for exact amounts.

Can I appeal if my child turns 12 months during RSV season? Yes, if your child met eligibility criteria at the start of RSV season, coverage should continue through the full season regardless of birthday timing during the season.

What documentation helps most in appeals? Birth records showing exact gestational age, NICU discharge summaries with oxygen requirements, current medical status from specialists, and clear explanation why Beyfortus is inappropriate.

When navigating complex prior authorization requirements, having the right documentation and understanding payer-specific workflows makes all the difference. Counterforce Health's platform helps families and clinicians identify denial reasons and draft targeted appeals using evidence that aligns with each insurer's specific policies and procedures.
