Answer Box: Getting Amondys 45 Covered by UnitedHealthcare in North Carolina

Amondys 45 (casimersen) requires prior authorization from UnitedHealthcare, with genetic testing confirming DMD amenable to exon 45 skipping as the primary requirement. Submit PA through OptumRx with complete genetic documentation, specialist records, and infusion plan. If denied, appeal within 60 days to OptumRx (fax: 1-844-403-1028), then use North Carolina's Smart NC external review (1-855-408-1212) for binding decisions within 45 days. First step today: Contact your neurologist to request genetic testing results and begin PA submission through the UnitedHealthcare provider portal.

Why North Carolina State Rules Matter

North Carolina's insurance laws provide crucial protections that work alongside UnitedHealthcare's policies. North Carolina General Statute § 58-50-61 mandates clear step therapy exception processes, requiring insurers to grant exceptions when preferred drugs are contraindicated, ineffective, or cause intolerable side effects.

For Amondys 45 specifically, this matters because there are no direct alternatives for exon 45 skipping. If UnitedHealthcare denies coverage citing step therapy requirements for other DMD treatments (like corticosteroids), North Carolina law requires they consider medical exceptions based on clinical evidence.

Line-of-business differences are important to understand:

  • Commercial plans: Follow North Carolina's 72-hour standard for step therapy exceptions, 24 hours for urgent cases
  • Medicare Advantage: Subject to CMS timelines (7 days standard, 72 hours expedited)
  • Medicaid managed care: Separate appeals process through NC Medicaid, not Smart NC
Note: Self-funded employer plans (ERISA plans) may not be subject to all North Carolina protections, but UnitedHealthcare's internal policies still apply.

UnitedHealthcare Prior Authorization Requirements

UnitedHealthcare requires prior authorization for Amondys 45 through OptumRx. Based on similar exon-skipping agents, expect these key requirements:

Coverage at a Glance

Requirement What It Means Where to Find It Source
Prior Authorization Must be approved before dispensing OptumRx portal or CoverMyMeds OptumRx PA Guidelines
Genetic Testing DMD with mutation amenable to exon 45 skipping FDA-approved genetic assays FDA Approval Documentation
Specialist Requirement Neurologist or neuromuscular specialist Provider credentials verification UnitedHealthcare Provider Directory
Infusion Plan Weekly IV administration plan Site of care documentation UHC Injection/Infusion Policy
Monitoring Plan Regular assessments of function/safety Clinical monitoring protocols Provider documentation

Site of Care Considerations

UnitedHealthcare covers both home and clinic infusion for specialty drugs in North Carolina. Home infusion is often preferred and uses specific HCPCS codes like S9329 for administration services. No explicit restrictions mandate clinic over home for Amondys 45, but verify patient-specific benefits through the provider portal.

Step Therapy and Medical Exceptions

North Carolina law requires UnitedHealthcare to provide step therapy exceptions when:

  1. The preferred drug is contraindicated
  2. The preferred drug produced inadequate response or intolerable adverse effects
  3. The preferred drug is expected to be ineffective based on clinical evidence

For Amondys 45, document these key points:

  • No other exon 45 skipping therapy exists
  • Patient has specific genetic mutation requiring this mechanism
  • Alternative DMD therapies (corticosteroids, other exon-skipping drugs) target different pathways

Medical Exception Timeline

  • Standard: 72 hours for step therapy exception decisions
  • Urgent: 24 hours when delay would jeopardize health or function

Patient Phone Script for UnitedHealthcare

"Hello, I'm calling about prior authorization for Amondys 45, also called casimersen, for my [child/family member] with Duchenne muscular dystrophy. We have genetic testing confirming an exon 45 mutation. Can you tell me the current status of our PA request submitted on [date]? If it's denied, I'd like to understand the specific reasons and start the appeal process immediately."

Clinician Peer-to-Peer Request Script

"I'm requesting a peer-to-peer review for [patient name]'s Amondys 45 denial. This patient has genetically confirmed DMD with an exon 45 mutation amenable to skipping. There are no therapeutic alternatives for this specific genetic variant. The FDA granted accelerated approval based on dystrophin upregulation data. I can provide the genetic testing, functional assessments, and clinical rationale for why this specific antisense therapy is medically necessary."

Medical Necessity Letter Template

"[Patient] has genetically confirmed Duchenne muscular dystrophy with a mutation amenable to exon 45 skipping, documented by [genetic test details]. Amondys 45 (casimersen) is the only FDA-approved therapy targeting this specific genetic variant through phosphorodiamidate morpholino oligomer (PMO) antisense technology. Alternative DMD therapies target different pathways and are not effective for this patient's specific genetic profile. Weekly intravenous administration is planned at [site of care] with appropriate monitoring per FDA labeling requirements."

FAQ

How long does UnitedHealthcare prior authorization take in North Carolina? Standard PA decisions take up to 45 days. Expedited reviews (when delay risks health) are completed within 72 hours. Use expedited processes whenever clinically appropriate.

What if Amondys 45 is non-formulary on my UnitedHealthcare plan? Non-formulary drugs can still be covered through the prior authorization process with strong medical necessity documentation. Focus on the lack of formulary alternatives for exon 45 skipping.

Can I request an expedited appeal in North Carolina? Yes. Both UnitedHealthcare and Smart NC offer expedited reviews when delays would jeopardize health or function. Document the urgency clearly in your request.

Does step therapy apply if my child failed treatments outside North Carolina? Yes, documented treatment failures from other states count toward step therapy requirements. Ensure all prior therapy attempts are well-documented in medical records.

What's the difference between UnitedHealthcare's internal appeals and Smart NC external review? Internal appeals are reviewed by UnitedHealthcare/OptumRx staff. Smart NC external review uses independent clinical reviewers and provides binding decisions that UnitedHealthcare must follow.

How does North Carolina's continuity of care law help with Amondys 45? North Carolina General Statutes § 58-67-88 provides up to 90 days of continued coverage during provider network changes or plan transitions for ongoing specialty therapy, potentially extendable for complex treatments.
