FAQ: Emflaza Coverage in California

How long does Aetna prior authorization take in California? California law requires decisions within 72 hours for standard requests and 24 hours for urgent cases. If Aetna doesn't respond within these timeframes, the request is automatically approved.

What if Emflaza is non-formulary on my plan? You can request a medical exception if Emflaza is medically necessary and formulary alternatives are inappropriate. Document why prednisone/prednisolone cannot be used.

Can I request an expedited appeal? Yes, if delay could seriously jeopardize your health. Your physician must provide a written statement of medical urgency. Expedited appeals are decided within 72 hours.

Does step therapy apply if I failed steroids in another state? Yes, documented steroid failure from any provider counts toward step therapy requirements. Ensure you have medical records showing the trial and reason for discontinuation.

What's the success rate for appeals in California? DMHC data shows approximately 73% of Independent Medical Review cases result in patients receiving requested treatment.

How much will Emflaza cost with Aetna coverage? Costs vary by plan design. Emflaza is typically on specialty tier (Tier 4-5) with higher copays or coinsurance. Check your specific plan documents for exact amounts.

Can I use manufacturer copay assistance? PTC Therapeutics offers patient support programs. Check eligibility and restrictions with your specific Aetna plan, as some government programs may limit copay card use.

What if I'm already on Emflaza and Aetna changes formulary? California continuity-of-care laws may protect ongoing therapy. If Emflaza was previously covered and is moved to PA or removed, coverage may continue as long as your prescriber deems it appropriate.
