Why Myths About Evrysdi Coverage Persist

Confusion around Evrysdi (risdiplam) coverage stems from the drug's complexity—it's an oral SMN2 splicing modifier for spinal muscular atrophy (SMA) that can cost up to $340,000 annually. With Humana's Medicare Advantage plans covering many Pennsylvania residents, misinformation spreads quickly through online forums and support groups.

The reality is that Humana requires prior authorization for Evrysdi, but their denial rate for Medicare Advantage is relatively low at 3.5% when proper documentation is provided. Understanding the facts can mean the difference between approval and a lengthy appeals process.

Common Myths vs. Facts

Myth 1: "If my neurologist prescribes Evrysdi, Humana must cover it"

Fact: Prior authorization is mandatory regardless of the prescriber's specialty. Humana requires specific documentation including genetic confirmation of SMA and baseline motor function assessments before approving coverage.

Myth 2: "I can't get Evrysdi if I've tried Spinraza or Zolgensma"

Fact: Previous SMA treatments don't automatically disqualify you. However, you'll need clear documentation showing continued disease progression or medical necessity for switching therapies. Many appeals succeed when prescribers explain why Evrysdi is appropriate despite prior treatments.

Myth 3: "Appeals take forever and rarely work"

Fact: Humana must respond to appeals within 7 days (standard) or 72 hours (expedited). Pennsylvania's new external review program, launched in 2024, overturns approximately 53% of denied claims, making it one of the most effective appeal routes in the country.

Myth 4: "Generic testing from any lab is sufficient"

Fact: Insurers require comprehensive genetic testing confirming biallelic SMN1 mutations and SMN2 copy number from recognized laboratories. Incomplete genetic reports are a leading cause of denials.

Myth 5: "I need to exhaust all other SMA treatments first"

Fact: While some plans require step therapy, Evrysdi can be first-line treatment when clinically appropriate. The key is demonstrating medical necessity through proper documentation, not following a rigid treatment sequence.

Myth 6: "Medicare Advantage plans have the same rules as traditional Medicare"

Fact: Humana's Medicare Advantage plans have their own formulary and prior authorization requirements, which may differ from traditional Medicare Part D. Always check your specific plan's coverage policies.

What Actually Influences Approval

Understanding Humana's actual approval criteria helps separate fact from fiction:

Required Documentation

  • Genetic confirmation: Laboratory report showing biallelic SMN1 mutations and SMN2 copy number
  • Clinical assessment: Baseline motor function evaluation using validated scales (Hammersmith Functional Motor Scale, CHOP INTEND)
  • Prescriber statement: Medical necessity letter from neurologist or neuromuscular specialist
  • Patient factors: Age, weight for dosing calculations, and current functional status

Coverage Criteria

According to Humana's prior authorization requirements, approval typically requires:

  • Confirmed SMA diagnosis through genetic testing
  • Age-appropriate motor function documentation
  • Clear treatment goals and monitoring plan
  • Justification if other SMA therapies have been tried
Counterforce Health helps patients and clinicians navigate these complex requirements by analyzing denial letters and crafting targeted appeals with the right evidence and documentation. Their platform identifies specific denial reasons and provides point-by-point rebuttals aligned to each plan's policies.

Avoid These Critical Mistakes

These five errors cause most preventable denials:

1. Incomplete Genetic Testing Documentation

Mistake: Submitting partial genetic reports or older testing results. Fix: Ensure genetic testing includes complete SMN1 and SMN2 analysis from a certified laboratory with clear confirmation of SMA diagnosis.

2. Missing Baseline Motor Assessment

Mistake: Lacking current motor function evaluation from a specialist. Fix: Schedule evaluation with neurologist or neuromuscular specialist who can provide standardized motor function scores.

3. Inadequate Medical Necessity Letter

Mistake: Generic letters that don't address patient-specific factors. Fix: Request detailed letter explaining why Evrysdi is medically necessary for your specific situation, including any contraindications to alternatives.

4. Ignoring Prior Treatment History

Mistake: Not addressing previous SMA therapies or treatment failures. Fix: Document response to prior treatments, reasons for discontinuation, and rationale for Evrysdi therapy.

5. Missing Appeal Deadlines

Mistake: Waiting too long to file appeals or missing Pennsylvania's 4-month external review window. Fix: Mark all deadlines immediately upon receiving denial letters and file appeals promptly.

Quick Action Plan: 3 Steps to Take Today

Step 1: Gather Essential Documentation (Today)

Contact your neurologist's office to request:

  • Complete genetic testing reports
  • Recent motor function assessments
  • Previous SMA treatment records
  • Current clinical notes with SMA diagnosis

Step 2: Initiate Prior Authorization (This Week)

Have your prescriber submit a prior authorization request through Humana's provider portal including all required documentation. Humana must respond within 72 hours for standard requests or 24 hours for expedited requests.

Step 3: Prepare for Potential Appeal (Within 30 Days)

From our advocates: "We've seen cases where initial denials were overturned simply by providing more detailed motor function documentation. One family received approval after their neurologist submitted updated CHOP INTEND scores showing disease progression, even though the initial request was denied for 'insufficient clinical justification.'"
