Frequently Asked Questions

How long does Aetna (CVS Health) prior authorization take in New York? Standard reviews take up to 15 business days once complete documentation is received. Expedited reviews are completed within 72 hours when delay poses serious health risk.

What if Zokinvy is non-formulary on my plan? Request a formulary exception with documentation that no formulary alternatives exist for HGPS or your specific progeroid laminopathy. This is typically approved given Zokinvy's unique indication.

Can I use a pharmacy other than CVS Specialty? Most Aetna plans require CVS Specialty for Zokinvy. You can request an out-of-network exception if another specialty pharmacy is clinically necessary, but this requires additional documentation.

Does step therapy apply if I've been stable on Zokinvy? Generally no. Counterforce Health has seen that most payers don't impose step therapy for Zokinvy renewals when patients are clinically stable, as no therapeutic alternatives exist for the FDA-approved indications.

What happens if my external appeal is denied? New York external appeal decisions are binding on insurers. If overturned in your favor, Aetna must cover the treatment and refund your appeal fee.
