How to Get Amondys 45 (casimersen) Covered by Cigna in California: Complete Prior Authorization, Appeals, and Forms Guide
Answer Box: Getting Amondys 45 Covered by Cigna in California
Cigna covers Amondys 45 (casimersen) for Duchenne muscular dystrophy patients under 14 years old with confirmed exon 45-amenable gene mutations, but requires prior authorization via Coverage Policy IP0137. Fastest path: Have your neuromuscular specialist submit genetic test results showing "exon 45 skipping amenable" mutation, recent 6-minute walk test (≥300 meters), and forced vital capacity ≥50% through Cigna's provider portal or CoverMyMeds. Standard approval takes 5-10 business days; expedited reviews complete in 24-72 hours. If denied, California residents can appeal internally within 180 days, then request Independent Medical Review through the DMHC—which is free and binding on Cigna.

Plan Types & Network Requirements
Cigna HMO vs PPO Coverage Differences
In California, Cigna offers both HMO and PPO plans with different network requirements that can impact your access to Amondys 45:
Cigna HMO (Cigna HealthCare of California, Inc.):
- Must use in-network providers and assigned medical group
- Requires PCP referrals for specialist care
- Prior authorization flows through your medical group
- No out-of-network coverage except emergencies
Cigna PPO (Cigna Health and Life Insurance Company):
- Can see any in-network provider without referrals
- Out-of-network options available at higher cost
- Direct specialist access for prior authorization
- More flexibility but higher premiums
Note: Both plan types require prior authorization for Amondys 45, but the coordination process differs. HMO members work through their assigned medical group, while PPO members can have any contracted specialist submit the request.
Network Provider Requirements
For Amondys 45 infusions, you'll need access to:
- Neuromuscular specialist (required for prescribing and monitoring)
- Infusion center (home infusion preferred; outpatient hospital acceptable)
- Accredo specialty pharmacy (Cigna's contracted partner)
Verify your providers are in-network before starting treatment by calling Cigna member services or checking the online provider directory.
