Why Myths About Exondys 51 Coverage Persist

Families facing Duchenne muscular dystrophy often encounter conflicting information about getting Exondys 51 (eteplirsen) covered by UnitedHealthcare. These myths persist because the approval process is genuinely complex, involving genetic testing requirements, specialist credentials, and strict functional criteria that change over time.

UnitedHealthcare's denial rates for specialty medications exceed industry averages, making initial denials common even for eligible patients. Understanding the facts—rather than relying on outdated information or assumptions—can mean the difference between coverage and costly appeals.

At Counterforce Health, we help patients and clinicians navigate these complex approval processes by turning insurance denials into targeted, evidence-backed appeals. Our platform identifies specific denial reasons and drafts point-by-point rebuttals aligned to each payer's own coverage policies.

Common Myths vs. Facts

Myth 1: "If my neurologist prescribes Exondys 51, UnitedHealthcare has to cover it."

Fact: UnitedHealthcare requires prior authorization with specific criteria, including genetic confirmation of exon 51-amenable mutations, ambulatory status without assistive devices, and either an NSAA score >17 or time-to-rise <7 seconds. Simply having a prescription isn't enough.

Myth 2: "Any pediatric neurologist can prescribe Exondys 51 for UnitedHealthcare coverage."

Fact: The prescriber must be a neurologist with expertise in DMD treatment or work in consultation with such a specialist. General pediatric neurology experience may not meet UnitedHealthcare's requirements.

Myth 3: "Since Exondys 51 is FDA-approved, step therapy doesn't apply."

Fact: UnitedHealthcare can still require documentation of prior corticosteroid therapy and may apply quantity limits or site-of-care restrictions even for FDA-approved medications.

Myth 4: "If UnitedHealthcare denies my appeal, I'm out of options in Illinois."

Fact: Illinois residents have robust external review rights through independent physician reviewers. You have 4 months from the final denial to request external review, and the process is free.

Myth 5: "I can't get coverage if my child has already tried gene therapy."

Fact: UnitedHealthcare's 2025 criteria allow coverage for patients who previously received gene therapy if they show documented functional decline from loss of muscle strength or motor function.

Myth 6: "Appeals take forever and rarely work."

Fact: Illinois requires fast timelines for external reviews—decisions within 5 business days once materials are received. External reviews overturn 40-60% of denials nationally when proper clinical evidence is presented.

Myth 7: "I need a lawyer to appeal UnitedHealthcare denials."

Fact: Illinois provides free consumer assistance through the Department of Insurance (877-850-4740) and Attorney General's Health Care Bureau (877-305-5145) to help with appeals and external reviews.

What Actually Influences UnitedHealthcare Approval

Genetic Documentation Requirements

UnitedHealthcare requires genetic testing confirming exon 51-amenable mutations. Approximately 13% of DMD patients have mutations amenable to exon 51 skipping, so this genetic confirmation is non-negotiable.

Functional Assessment Criteria

Patients must demonstrate ambulatory function through either:

  • North Star Ambulatory Assessment (NSAA) score greater than 17, OR
  • Time to rise (TTR) of less than 7 seconds

Medical records must confirm ambulatory status without assistive devices (no cane, walker, or wheelchair).

Prescriber Credentials

The neurologist must have documented expertise in DMD treatment. MDA clinic affiliations and board certifications in neuromuscular medicine strengthen applications.

Monitoring Requirements

UnitedHealthcare requires baseline and ongoing monitoring:

  • Annual cardiac assessment (echocardiogram or cardiac MRI)
  • Renal function tests (serum creatinine, urinalysis)
  • Documentation of continued ambulatory status for renewals

Avoid These Critical Mistakes

1. Submitting Incomplete Genetic Documentation

Don't assume genetic testing from years ago meets current requirements. UnitedHealthcare needs specific confirmation of exon 51 amenability, not just a DMD diagnosis.

2. Missing Electronic Submission Deadlines

As of August 2025, UnitedHealthcare requires electronic submission through their provider portal. Fax submissions are no longer accepted for most prior authorizations.

3. Waiting Too Long to Start Renewals

Begin the renewal process 60-90 days before expiration. Coverage gaps can occur if renewal submissions are delayed.

4. Ignoring Illinois-Specific Appeal Deadlines

Illinois has a shorter external review window than many states—you must request external review within 4 months of the final denial, not the federal 180-day standard.

5. Appealing Without Addressing Specific Denial Reasons

Generic appeals rarely succeed. Address each denial reason with targeted clinical evidence that directly references UnitedHealthcare's own policy criteria.

Your 3-Step Action Plan

Step 1: Verify Prescriber Qualifications Today

Contact your neurologist's office to confirm they meet UnitedHealthcare's requirement for DMD expertise. If not, request a consultation with a qualified specialist or MDA clinic.

Step 2: Gather Required Documentation

Collect these essential documents before submitting:

  • Genetic testing report confirming exon 51-amenable mutation
  • Recent functional assessments (NSAA or time-to-rise tests)
  • Baseline cardiac and renal function tests
  • Documentation of ambulatory status without assistive devices

Step 3: Submit Through Electronic Portal

Use UnitedHealthcare's electronic prior authorization system rather than fax. The electronic system provides immediate confirmation and tracking numbers.

From our advocates: Families who succeed with UnitedHealthcare often coordinate closely with their specialty pharmacy to ensure all documentation addresses the insurer's specific policy requirements. Having the pharmacy review your submission packet before the provider submits can catch missing elements that commonly cause denials.

Illinois-Specific Appeal Rights
