Who Should Use This Guide

This guide helps patients with spinal muscular atrophy (SMA) and their healthcare providers navigate Humana's prior authorization process for Evrysdi (risdiplam) in North Carolina. You'll need this if:

  • Your doctor has prescribed Evrysdi for confirmed SMA
  • You have Humana Medicare Advantage, Medicare Part D, or commercial insurance
  • You're facing a prior authorization requirement or denial
  • You need to understand North Carolina's external review rights

Expected outcome: With complete documentation, Humana approves most medically necessary requests. Their Medicare Advantage denial rate is approximately 3.5%—among the lowest of major insurers—when proper documentation is provided.

Member & Plan Basics

Coverage Requirements

Prior Authorization: Required for all Humana plans covering Evrysdi. The medication typically appears on Humana's Prior Authorization and Notification List as a Tier 5 specialty drug.

Plan Types Covered:

  • Humana Medicare Advantage (Part C)
  • Humana Medicare Part D stand-alone plans
  • Humana commercial plans (employer-sponsored)

Cost Considerations: Evrysdi's list price approaches $340,000 annually, making it subject to highest-tier cost-sharing. Medicare Part D beneficiaries may qualify for catastrophic coverage after reaching the annual out-of-pocket threshold.

Note: New Humana members have a 90-day grace period for ongoing treatments started before enrollment, but prior authorization is still required for continued coverage.

Clinical Criteria for Approval

Primary Requirements

Requirement Documentation Needed Source
SMA Diagnosis Genetic testing showing SMN1 gene deletion ICD-10: G12.0, G12.1
Age Eligibility Pediatric and adult patients FDA labeling
Motor Function Baseline assessments (CHOP INTEND, HFMSE) Clinical documentation
Specialist Care Neurologist or SMA specialist involvement Provider notes

Genetic Testing Requirements

Medicare covers SMN1 deletion confirmation testing without prior authorization under CPT codes 81329 (dosage analysis) and 81320 (targeted mutation). The test must show:

  • Homozygous deletion of SMN1 gene exon 7 (with or without exon 8 deletion)
  • SMN2 copy number if available (affects prognosis but not coverage)
  • Genetic counseling documentation recommended

No Step Therapy Required

Unlike some insurers, Humana doesn't mandate trying Spinraza or Zolgensma first if Evrysdi is clinically appropriate as initial therapy. However, document any prior SMA treatments and outcomes.

Required Documentation Packet

Medical Necessity Letter Components

Your prescriber should include these elements in the letter of medical necessity:

Patient Information:

  • Current age and weight (for dosing calculations)
  • SMA type and severity
  • Current motor function status
  • Functional decline or stability goals

Clinical Justification:

  • Genetic testing results confirming SMA
  • Motor assessments (baseline and recent)
  • Why Evrysdi is preferred over alternatives
  • Treatment goals and monitoring plan

Supporting Evidence:

Required Attachments

  • Genetic testing report (SMN1 deletion confirmation)
  • Recent motor function assessments
  • Specialist consultation notes
  • Prior treatment records (if applicable)
  • Current weight documentation (for dosing)
  • Pregnancy test results (females of reproductive age)

Submission Process

Step-by-Step Submission

  1. Gather Documentation (1-2 days)
    • Collect all required clinical records
    • Ensure genetic testing is complete and recent
  2. Complete Prior Authorization Form
    • Access through Humana's provider portal
    • Use current form version (verify date)
    • Include all required fields to prevent automatic rejections
  3. Submit Complete Package
    • Standard review: 72 hours from complete submission
    • Expedited review: 24 hours if urgent medical need
    • Request confirmation number and save it
  4. Verify Submission
    • Check portal status within 24 hours
    • Confirm all documents were received
    • Note any missing information requests
Tip: Submit early in the week (Tuesday-Thursday) for faster processing, as weekends can delay review timelines.

Specialty Pharmacy Requirements

Network Requirements

Evrysdi must be dispensed through Humana's specialty pharmacy network. CenterWell Specialty Pharmacy (formerly Humana Specialty Pharmacy) is the preferred vendor, but other network options may be available.

Services Provided:

  • Home delivery coordination
  • Clinical monitoring support
  • Financial assistance program navigation
  • Dosing and administration education

Prescription Transfer Process

  1. Verify network status of chosen specialty pharmacy
  2. Transfer prescription from retail pharmacy if needed
  3. Coordinate delivery to preferred location
  4. Confirm receipt and proper storage instructions

Using an out-of-network specialty pharmacy will result in automatic coverage denial.

From our advocates: We've seen several North Carolina patients successfully overturn Evrysdi denials through Smart NC's external review process, particularly when the initial denial cited "experimental" status despite FDA approval. The key was submitting comprehensive clinical trial data and FDA prescribing information to demonstrate established efficacy.

Common Denial Reasons & How to Fix Them

Denial Reason Solution Documentation Needed
Missing genetic confirmation Submit SMN1 deletion test results Lab report showing homozygous SMN1 exon 7 deletion
Inadequate motor assessment Provide baseline and recent scores CHOP INTEND, HFMSE, or other validated scales
Dosing documentation gaps Include current weight and calculation Recent clinic visit with weight documentation
"Experimental" designation Challenge with FDA approval evidence FDA prescribing information and clinical trial data
Duplicate therapy concern Clarify treatment history Records showing Spinraza/Zolgensma discontinuation or rationale

When to Request Peer-to-Peer Review

If initial documentation doesn't resolve the denial, request a peer-to-peer review between your prescribing physician and Humana's medical director. This is particularly effective for:

  • Complex cases with multiple comorbidities
  • Unusual dosing requirements
  • Questions about treatment sequencing
