What This Guide Covers

This guide helps families and healthcare providers navigate Humana's prior authorization process for Zolgensma (onasemnogene abeparvovec) in North Carolina. Zolgensma is a one-time gene therapy for spinal muscular atrophy (SMA) with a list price of approximately $2.125 million, making insurance coverage essential for most families.

We'll walk you through every step, from initial documentation to appeals, including North Carolina's unique Smart NC external review process that gives you additional protection when dealing with denials.

Before You Start: Plan Verification

Confirm Your Humana Plan Type

Different Humana plans have varying requirements:

  • Medicare Advantage: Standard 30-day review for pre-service decisions
  • Commercial plans: Follow state-mandated timelines (typically 15 business days)
  • Medicaid: Specific state formulary requirements apply

Call Humana member services at the number on your insurance card to confirm your exact plan type and benefits.

Verify Network Status

Zolgensma must be administered at a Humana in-network hospital or infusion center. The medication is covered under your medical benefit, not pharmacy benefit, and requires specialized administration capabilities.

Check Formulary Status

Humana's 2024 formulary lists Zolgensma as a specialty drug requiring prior authorization across all plan types. The medication is typically covered but subject to strict medical necessity criteria.

Gather Required Documentation

Laboratory Requirements:

  • Anti-AAV9 antibody titer ≤ 1:50

  • Complete blood count with platelets
  • All labs must be recent (typically within 30 days)

Clinical Assessment:
