FAQ

Q: How long does Aetna CVS Health prior authorization take for Rylaze in Texas? A: Standard PA decisions are made within 30 days. Expedited requests (when delay would jeopardize health) must be decided within 72 hours per Texas law.

Q: What if Rylaze is not on Aetna's formulary? A: Request a formulary exception with the same clinical documentation. Non-formulary status doesn't prevent coverage if medically necessary.

Q: Can I request an expedited appeal if my PA is denied? A: Yes, if treatment delay would seriously jeopardize your health. Mark your appeal "URGENT" and provide clinical justification.

Q: Does step therapy apply if I failed E. coli asparaginase outside Texas? A: No, documented hypersensitivity from any location should qualify you for Rylaze coverage without step therapy requirements.

Q: What happens if my internal appeal is denied? A: You can request external review by a Texas Independent Review Organization (IRO) within 4 months. The IRO decision is binding on Aetna.

Q: How much does Rylaze cost without insurance? A: Retail prices can exceed $5,800 per dose. Contact Jazz Cares for patient assistance programs.

Q: Can Rylaze be given at home? A: Generally no. Most insurers require administration in medically supervised outpatient settings due to monitoring requirements for potential severe reactions.

Q: What if I have an ERISA self-funded employer plan? A: These plans follow federal appeal rules, not Texas IRO process. Contact your HR department to understand your specific appeal rights.

From our advocates: We've seen families succeed by being very specific about the hypersensitivity reaction details—exact dates, symptoms, treatments given, and hospital discharge summaries. One family's appeal was initially denied because they wrote "allergic reaction" but was approved when they resubmitted with emergency department records showing anaphylaxis requiring epinephrine. Documentation specificity makes the difference.

The appeals process can feel overwhelming, but understanding Aetna's specific requirements and Texas law provides multiple pathways to coverage. For complex cases involving repeated denials, specialized appeal services like Counterforce Health can help craft targeted responses that address each payer's specific coverage criteria and procedural requirements.
