When to Start Your Renewal Process

Timing Windows That Matter

Your Exondys 51 prior authorization typically expires after 12 months. Don't wait until the last minute—UnitedHealthcare's review process can take 15-30 business days, and you may need time to gather additional documentation if requested.

Start 60-90 days early if:

  • You've had coverage gaps or denials before
  • Your clinical status has changed (new cardiac issues, mobility changes)
  • You're switching between UnitedHealthcare plan types (Commercial to Medicare Advantage, etc.)
  • Your neurologist has changed or retired

Start 30-45 days early if:

  • Your previous renewals went smoothly
  • Your clinical status is stable
  • All required documentation is readily available
Tip: Set a calendar reminder for 90 days before your authorization expires. Most denial letters include the expiration date, or you can check through the UnitedHealthcare member portal.

Signs You Should Start Early

Watch for these renewal triggers that may complicate your case:

  • New cardiac abnormalities on recent echocardiogram
  • Changes in walking ability or time to rise measurements
  • Missed infusions or treatment interruptions
  • Switch to a new neurologist or treatment center
  • Changes to your UnitedHealthcare plan (formulary updates, benefit changes)

2025 Policy Changes You Need to Know

UnitedHealthcare updated its Exondys 51 coverage criteria in 2025, with changes effective May 1, 2025 for Community Plans and July 1, 2025 for Exchange Plans. Here's what changed:

Updated Motor Function Requirements

Previous requirement: General ambulatory status
New requirement: Time to rise (TTR) of less than 7 seconds, documented in clinical notes

This expands coverage slightly from the previous "Gower's test" language but requires specific measurement documentation.

Expanded Exclusion List

The 2025 policy explicitly prohibits concurrent use with:

  • Amondys 45 (casimersen)
  • Viltepso (viltolarsen)
  • Vyondys 53 (golodirsen)
  • New: Cipla's generic versions of exon-skipping therapies

State-Specific Exceptions

If you live in Florida, Kansas, Louisiana, or Mississippi (Community/Medicaid plans) or Massachusetts, Nevada, or New York (Exchange plans), your state may have different rules that supersede UnitedHealthcare's standard policy.


Required Documentation Checklist

Based on UnitedHealthcare's 2025 renewal requirements, gather these documents for your renewal:

Clinical Documentation

  • Neurologist evaluation (within 6 months) confirming continued DMD diagnosis
  • Time to rise test results showing <7 seconds
  • Treatment response documentation (6-minute walk test, functional assessments)
  • Infusion adherence records from specialty pharmacy or infusion center

Laboratory and Monitoring

  • Annual cardiac assessment (echocardiogram or cardiac MRI within 12 months)
  • Renal function tests (serum creatinine, urinalysis within 12 months)
  • Updated prescription with current dosing based on weight

Administrative Requirements

  • Genetic testing confirmation of exon 51 amenable mutation (if not on file)
  • Prior authorization renewal form completed by prescriber
  • Insurance verification that your plan still covers Exondys 51
Clinician Corner: The medical necessity letter should emphasize continued clinical benefit, even if functional measures remain stable rather than improved. Document any slowing of disease progression compared to natural history expectations.

If Your Coverage Lapses: Bridge Options

If your renewal is delayed or denied, you have several options to maintain access to Exondys 51:

Emergency/Continuity Supply

Contact OptumRx specialty pharmacy immediately to request a temporary bridge supply while coverage is restored. Many specialty pharmacies have established protocols for rare disease medications.

What to say: "I need an emergency fill for Exondys 51 while my prior authorization renewal is being processed. This is for a progressive rare disease and interruption could cause permanent harm."

Manufacturer Support Programs

Sarepta Therapeutics offers patient assistance through their Exondys 51 support program. They may provide temporary supply during coverage gaps.

Appeal While Continuing Treatment

In North Carolina, you can often continue receiving treatment during the appeals process, especially for life-sustaining medications. Discuss this with your healthcare team and insurance coordinator.

From our advocates: "We've seen patients successfully maintain Exondys 51 access during coverage transitions by immediately contacting both the specialty pharmacy and manufacturer support program. The key is acting quickly—don't wait to see if the issue resolves itself."

FAQ

How long does UnitedHealthcare PA renewal take in North Carolina? Standard renewals take 15-30 business days. Urgent requests (when delay could harm health) are processed within 72 hours.

What if my neurologist is no longer in-network? UnitedHealthcare may grant a continuity of care exception, allowing you to continue with your current neurologist during transition. Request this immediately when you learn of network changes.

Can I request expedited renewal if my authorization is about to expire? Yes, if interruption would seriously jeopardize your health. Document the urgency and submit through your healthcare provider with supporting clinical evidence.

Does North Carolina's external review cover self-funded employer plans? Not automatically, but some self-funded plans opt into North Carolina's external review system. Smart NC can help determine your plan's eligibility.

What happens if I miss doses during a coverage gap? Contact your neurologist immediately. They may recommend adjusting your restart protocol and will need to document any treatment interruption in future renewal requests.
