Step-by-Step: Prior Authorization Process

1. Confirm Coverage Status (Patient/Family)

Timeline: 1-2 business days
Action: Call Humana Member Services at the number on your insurance card to verify Zolgensma coverage under your specific plan and confirm current PA requirements.

2. Genetic Testing Documentation (Clinic)

Timeline: 2-4 weeks
Required: SMN1 gene deletion or mutation confirmation from a certified laboratory. Your neurologist will order this if not already completed.

3. Baseline Medical Assessments (Clinic)

Timeline: 1-2 weeks
Required: Anti-AAV9 antibody testing (must be negative), complete blood count, liver function tests, and motor function assessment.

4. Medical Necessity Letter (Neurologist)

Timeline: 3-5 business days
Must include: Confirmed diagnosis with ICD-10 code, genetic test results, patient age verification, treatment urgency rationale, and steroid pre-medication plan.

5. Prior Authorization Submission (Clinic)

Timeline: Same day
Method: Submit through Humana provider portal with all documentation attached. Verify current submission process with Humana.

6. Initial Decision (Humana)

Timeline: 30 days standard, 72 hours expedited
Follow-up: If no response within timeline, contact Humana to check status and request expedited review if medically urgent.

7. Appeal if Denied (Patient/Clinic)

Timeline: Must start within 65 days
Process: Submit internal appeal with additional evidence, request peer-to-peer review, or escalate to Washington external review.

When Alternatives Make Sense

Before pursuing appeals or exceptions for Zolgensma, consider whether alternative SMA treatments might be more accessible through your Humana plan. Alternatives may be appropriate when:

  • Age restrictions apply: Zolgensma is FDA-approved only for patients under 2 years
  • Positive AAV9 antibodies: Contraindication for gene therapy
  • Family preference: Some families prefer ongoing treatments over one-time gene therapy
  • Coverage barriers: When prior authorization repeatedly fails and urgent treatment is needed

Counterforce Health specializes in turning insurance denials into successful appeals by identifying the specific denial basis and crafting evidence-backed rebuttals aligned to each plan's requirements.

Typical SMA Treatment Alternatives

Spinraza (Nusinersen)

Mechanism: Intrathecal injection that modifies SMN2 pre-mRNA splicing
Administration: Loading doses followed by maintenance every 4 months
Coverage: Covered by Humana with prior authorization
Age range: No upper age limit

Evrysdi (Risdiplam)

Mechanism: Oral SMN2 splicing modifier taken daily
Administration: Liquid formulation, can be given at home
Coverage: Generally formulary-covered with step therapy requirements
Age range: 2 months and older

Note: Humana requires that patients cannot use multiple SMA disease-modifying therapies concurrently unless specifically approved through exception process.

Pros and Cons of Treatment Options

Zolgensma Advantages

  • One-time treatment: No ongoing injections or daily medication
  • Proven efficacy: Significant motor improvements in clinical trials
  • Convenience: Single infusion eliminates long-term treatment burden

Zolgensma Considerations

  • Age restriction: Must be under 2 years old
  • Cost barrier: $2.1 million list price creates coverage challenges
  • Pre-treatment requirements: Extensive testing and steroid pre-medication needed

Alternative Therapy Benefits

  • Broader eligibility: Spinraza and Evrysdi have fewer age restrictions
  • Established coverage: More predictable insurance approval pathways
  • Flexibility: Can switch between therapies based on response

Alternative Therapy Limitations

  • Ongoing treatment: Requires lifelong commitment to injections or daily medication
  • Access challenges: Spinraza requires specialized administration sites
  • Variable response: Not all patients achieve optimal motor improvements

Exception Strategy for Non-Formulary Status

If Zolgensma isn't covered under your Humana formulary, request a formulary exception rather than accepting denial. Your neurologist must demonstrate that:

Medical Necessity Criteria

  1. All formulary alternatives would be less effective for your child's specific presentation
  2. Covered alternatives would cause adverse effects based on individual risk factors
  3. Standard step therapy has failed or is contraindicated

Supporting Evidence to Include

  • Genetic testing results showing specific SMN1 mutations
  • Motor function assessments demonstrating rapid progression
  • Age documentation showing urgency due to treatment window
  • Literature citations supporting gene therapy for your child's SMA type
  • Contraindications to alternative therapies if applicable

Submit exception requests through the same Humana provider portal used for prior authorization, ensuring all clinical documentation supports medical necessity.

Appeals Playbook for Humana in Washington

Internal Appeal (First Level)

Timeline: 65 days from denial notice
Decision time: 30 days standard, 72 hours expedited
Submit to: Humana Member Services or provider portal
Required: Original denial letter, additional medical evidence, updated physician letter

Expedited Appeal Process

When to use: Treatment delay could seriously harm health
Timeline: 72-hour decision requirement
Contact: Humana Member Services with urgent medical justification

External Review (Washington State)

Timeline: 180 days after final internal denial

Contact: Washington OIC Consumer Advocacy at 1-800-562-6900
Decision: 30 days standard, 72 hours expedited

From our advocates: We've seen families successfully overturn Zolgensma denials by submitting peer-reviewed studies showing gene therapy's superiority for their child's specific SMA type, combined with documentation that alternative therapies failed to prevent motor decline. The key is matching clinical evidence to the plan's own medical necessity criteria.

Washington's external review process assigns an Independent Review Organization (IRO) with SMA specialists who can override Humana's denial if medical necessity is established. This process has helped many families access cutting-edge treatments initially denied by insurers.

Switching Between SMA Therapies

Coordination Requirements

If your child is currently on Spinraza or Evrysdi, switching to Zolgensma requires:

  • 6-12 month minimum between stopping current therapy and starting gene therapy
  • Documentation of current treatment response through motor function assessments
  • Updated medical necessity justification for switching therapies
  • Coordination between current treating team and gene therapy center

Provider Communication

Your neurologist should document:

  • Response to current therapy (improvements, stabilization, or decline)
  • Clinical rationale for switching to one-time gene therapy
  • Safety considerations for treatment transition
  • Monitoring plan during therapy switch

Re-Trying for Zolgensma Later

If initial prior authorization fails, you can resubmit with additional evidence. Document during any alternative therapy trial:

What to Track

  • Motor function changes with standardized assessments (HFMSE, CHOP-INTEND)
  • Adverse effects from current treatments
  • Quality of life impacts from ongoing therapy requirements
  • Disease progression despite alternative treatments

Resubmission Strategy

  • Wait 30-60 days before resubmitting unless clinical urgency requires sooner
  • Address specific denial reasons with targeted evidence
  • Include new clinical data showing inadequate response to alternatives
  • Request peer-to-peer review with Humana's medical director

Counterforce Health helps families and providers build stronger resubmission cases by analyzing denial patterns and crafting appeals that directly address payer concerns with clinical evidence.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn
"Not medically necessary" Submit peer-reviewed studies, FDA labeling, and specialty society guidelines supporting gene therapy for your child's SMA type
"Alternative therapies available" Document failures, intolerances, or contraindications to Spinraza/Evrysdi with clinical evidence
"Age criteria not met" Provide birth certificate and medical records confirming age under 2 years
"Missing genetic testing" Submit certified laboratory report showing SMN1 deletion/mutation
"Positive AAV9 antibodies" Retest after appropriate interval if initial test was false positive
"Non-formulary drug" File formulary exception with medical necessity documentation
