Renewing Amondys 45 (Casimersen) Approval with Cigna in Florida: Complete Timeline and Documentation Guide
Answer Box: Renewing Amondys 45 Coverage with Cigna in Florida
Cigna approves Amondys 45 (casimersen) renewals for 6-month periods in Florida, requiring proof of continued walking ability (300+ meters in 6 minutes), ongoing specialist care, and stable kidney function. Start your renewal 30-45 days before expiration to avoid treatment gaps. Submit through Cigna's CoverMyMeds portal with updated chart notes, walk test results, and lab values. If coverage lapses, request an emergency 31-day supply immediately while appealing through Florida's external review process.
First step today: Contact your neurologist to schedule your 6-minute walk test and updated pulmonary function assessment at least 6 weeks before your current approval expires.

Renewal Triggers: When to Start the Process
Cigna's Amondys 45 approvals in Florida operate on 6-month cycles, not annual renewals like many other specialty drugs. This shorter window means you'll need to stay proactive about timing.
Key Renewal Triggers
Start 45 days early if:
- Your last 6-minute walk test showed declining distance (even if still above 300 meters)
- You've had any respiratory infections or hospitalizations
- Your pulmonary function tests are trending downward
- You're approaching the transition from ambulatory to non-ambulatory status
Start 30 days early for routine renewals when:
- Your walking ability remains stable
- No significant health changes since last approval
- All monitoring labs are within normal ranges
Note: Unlike some specialty drugs where "stable disease" is sufficient, Cigna specifically requires continued ambulatory function for Amondys 45 renewals. This means you must still be able to walk independently.
Warning Signs to Start Early
Watch for these indicators that suggest you should begin renewal paperwork immediately:
- Forced vital capacity dropping below 60% (though 50% is the cutoff)
- Any kidney function changes on quarterly labs
- Difficulty completing your usual daily activities
- New cardiac symptoms requiring evaluation
Evidence Update: What Cigna Needs to See
Cigna's renewal criteria focus on three core areas: continued clinical benefit, safety monitoring, and specialist oversight. Here's what documentation must demonstrate:
Functional Status Requirements
6-Minute Walk Test Results:
- Must show ability to walk at least 300 meters independently
- Test should be performed within 30 days of renewal submission
- Include comparison to previous test results
- Document any assistive devices used (if any)
Pulmonary Function:
- Forced vital capacity must remain ≥50% predicted
- Submit spirometry results from past 3 months
- Include trends from previous assessments
Safety Monitoring Documentation
Kidney Function Labs (every 3 months):
- Serum cystatin C levels
- Urine protein-to-creatinine ratio
- Urinalysis with microscopy
Monthly Monitoring:
- Urine dipstick results
- Any signs of proteinuria or hematuria
- Documentation of how any abnormalities were addressed
Tip: DMD patients often have reduced muscle mass affecting creatinine levels, which is why Cigna specifically requires cystatin C rather than standard creatinine measurements.
Specialist Oversight Verification
Your renewal must include documentation that care continues under:
- Board-certified neurologist
- Neuromuscular specialist, OR
- Muscular Dystrophy Association (MDA) clinic physician
The specialist must provide updated clinical notes addressing:
- Current functional status
- Response to therapy over the past 6 months
- Any adverse events or complications
- Plan for continued monitoring

Bridge Therapy Reality Check
Important limitation: There are no alternative DMD therapies that provide the same exon 45 skipping mechanism as Amondys 45. Express Scripts' 2025 formulary specifically notes "no alternatives recommended" for this indication.
Focus on rapid renewal rather than therapy switching:
- Manufacturer patient assistance programs may provide temporary supply
- Clinical trial enrollment (if available and appropriate)
- Out-of-pocket purchase as absolute last resort (costs exceed $300,000 annually)
Florida-Specific Escalation Steps
If emergency supply is denied:
- File expedited internal appeal with Cigna (decision required within 15 days)
- Contact Florida Department of Financial Services at 1-877-693-5236
- Request external review if internal appeal fails (decision within 72 hours for urgent cases)

FAQ: Common Renewal Questions
Q: How long does Cigna take to process Amondys 45 renewals in Florida? A: Standard renewals take 5-7 business days for complete submissions. Incomplete applications requiring additional information may take 10-14 days. Expedited reviews for urgent situations are completed within 72 hours.
Q: What happens if my 6-minute walk distance drops below 300 meters? A: This typically results in denial since continued ambulatory function is required for renewal. However, you can appeal with documentation of other clinical benefits or if the decline is temporary due to illness or injury.
Q: Can I get Amondys 45 covered if it's not on Cigna's formulary? A: Yes, through formulary exception requests. You'll need strong medical necessity documentation and evidence that no covered alternatives are appropriate for exon 45-amenable DMD.
Q: What if my specialist moves or is no longer available? A: Establish care with a new qualified specialist (neurologist, neuromuscular specialist, or MDA clinic physician) before your renewal is due. The new specialist will need to review your case and provide updated medical necessity documentation.
Q: Are there any manufacturer assistance programs for Amondys 45? A: Sarepta Therapeutics offers patient assistance programs. Contact their patient services at 1-888-SAREPTA (1-888-727-3782) to discuss eligibility and application processes.
Q: What lab monitoring is required during Amondys 45 therapy? A: Kidney function monitoring includes monthly urine dipstick tests and quarterly serum cystatin C and urine protein-to-creatinine ratio measurements. Regular monitoring is essential due to potential kidney toxicity risks.
Q: Can I request an expedited renewal review? A: Yes, if you have urgent medical circumstances or if delays could jeopardize your health. Contact Cigna member services to request expedited processing and provide supporting documentation from your specialist.
Q: What should I do if Cigna requests a peer-to-peer review? A: Your specialist will need to speak directly with a Cigna medical director. Prepare them with your complete medical history, current functional status, and evidence supporting continued therapy necessity.
